  • Why are my USB 2.0 devices crashing Windows XP?

    - by BenAlabaster
    Background on the machine I'm having a problem with: The machine was inherited and appears to be circa 2003 (there's a date stamp on the power supply which leads me to this conclusion). I've got it set up as a Skype terminal for my 2 year old to keep in touch with her grandparents and other members of the family - which everyone loves. It has a generic ATX motherboard with no identifying markings other than one stamp that says "Rev.B". CPU-Z identifies the motherboard model as VT8601 but doesn't provide me with any manufacturer name. On board it has 1 x 10/100 LAN, 2 x USB 1.0, VGA, PS/2 for KB and mouse, parallel port, 2 x serial ports, 2 x IDE, 1 x floppy, 2 x SDRAM slots, 1 x CPU housing that is seating a 1.3GHz Intel Celeron CPU, 3 x PCI, 1 x AGP - although you can only use 2 of the PCI slots if you use the AGP slot due to the physical layout of the board. It's got 768Mb PC133 SDRAM - 1 x 512Mb & 1 x 256Mb installed as well as a D-LINK WDA-2320 54G Wi-Fi network card and a generic USB 2.0 expansion board containing 3 x external + 1 x internal USB connectors. It has a DVD+/-RW running as master on IDE1 and a 1.44Mb 3.5" floppy drive connected to the floppy connector. It has an 80Gb Western Digital hard drive running as master on IDE0. All this is sitting in a slimline case. I don't know the wattage of the PSU, but can post this later if this proves to be helpful. The motherboard is running a version of Award BIOS for which I don't have the version number to hand but can again post this later if it would be helpful. The hard disk is freshly formatted and built with Windows XP Professional/Service Pack 3 and is up to date with all current patches. In addition to Windows XP, the only other software it's running is Skype 4.1 (4.2 hangs the whole machine as soon as it starts up, requiring a hard boot to recover). It's got a Daytek MV150 15" touch screen hooked up to the on board VGA and COM1 sockets with the most current drivers from the Daytek website and the most current version of ELO-Touchsystems drivers for the touch component. The webcam is a Logitech Webcam C200 with the latest drivers from the Logitech website. The problem: If I hook any devices to the USB 2.0 sockets, it hangs the whole machine and I have to hard boot it to get it back up. If I have any devices attached to the USB 2.0 sockets when I boot up, it hangs before Windows gets to the login prompt and I have to hard boot it to recover. Workarounds found: I can plug the same devices into the on board USB 1.0 sockets and everything works fine, albeit at reduced performance. I've tried 3 different kinds of USB thumb drives, 3 different makes/models of webcams and my iPhone all with the same effect. They're recognized and don't hang the machine when I hook them to the USB 1.0 but if I hook them to the USB 2.0 ports, the machine hangs within a couple of seconds of recognizing the devices were connected. Attempted solutions: I've seen suggestions that this could be a power problem - that the PSU just doesn't have the wattage to drive these ports. While I'm doubtful this is the problem [after all the motherboard has the same standard connector regardless of the PSU wattage], I tried disabling all the on board devices that I'm not using - on board LAN, the second COM port, the AGP connector etc. through the BIOS in what I'm sure is a futile attempt to reduce the power consumption... I also modified the ACPI and power management settings. It didn't have any noticeable affect, although it didn't do any harm either. Could the wattage of the PSU really cause this problem? If it can, is there anything I need to be aware of when replacing it or do I just need to make sure it's got a higher wattage than the current one? My interpretation was that the wattage only affected the number of drives you could hook up to the power connectors, is that right? I've installed the USB card in another machine and it works without issue, so it's not a problem with the USB card itself, and Windows says the card is installed and working correctly... right up until I connect a device to it. The only thing I haven't done which I only just thought of while writing this essay is trying the USB 2.0 card in a different PCI slot, or re-ordering the wi-fi and USB cards in the slots... although I'm not sure if this will make any difference - does anyone have any experience that would suggest this might work? Other thoughts/questions: Perhaps this is an incompatibility between the USB 2.0 card and the BIOS, would re-flashing the BIOS with a newer version help? Do I need to be able to identify the manufacturer of the motherboard in order to be able to find a BIOS edition specific for this motherboard or will any version of Award BIOS function in its place? Question: Does anyone have any ideas that could help me get my USB 2.0 devices hooked up to this machine?

  • RAM module randomly stopped working

    - by nhinkle
    My laptop is a Dell Inspiron e1505. It came with 2x512 MB of RAM installed, and about a year and a half ago I decided to upgrade it to 2x1 GB. I bought two 1GB memory modules from newegg and installed them, and all worked fine. Just last night my laptop was working fine; this morning I booted up and there was a BIOS warning saying "amount of system memory has changed". I tried reseating the modules, but that didn't fix it. Then I removed each one individually, and determined that one of the sticks appears to no longer be working. This happened very abruptly - I hadn't noticed any problems which might have been indicative of impending failure. Does anybody have any clue what may have caused this, and if there's any hope of making it work again? The memory only had a 30 day warranty, so I can't RMA it.

  • HP ML150 G6 upgrading RAM/CPU beyond specs?

    - by Morten Green Hermansen
    I am being told that some limits on some HP servers can be crossed. Do any of you have any experience with that? A ML150/G6 is limited to 48GB RAM but I have been talking to a German company that guaranties me that this server will be able to be upgraded to 384GB RAM (using 32GB memory modules and 2 CPUs) http://www.compuram.de/en/memory,HP+%28-Compaq%29,Server,Proliant,ML150+G6.htm Can this really be true? The server that I have is using E5504 CPUs but will I be able to upgrade to any CPU that is using a LGA1366 socket? All from a low wattage L5640 all the way to the 6 core, high wattage versions like an X5650? (If cooling and power is adequate ofcause). Is there any limitation with powerregulators and chipset (Intel 5500). I am looking forward to any reply. Thanks in advance and best regards, - Morten Green Hermansen, Fanitas

  • Why is my Asus P5PL2-E using 640MB of RAM (out of 4GB) ? [closed]

    - by Tom
    Possible Duplicate: Windows XP and RAM 3.5GB+ I've recently installed 4GB of RAM on my server, which is running Windows XP SP2 32-bit and My Computer showed that only 3.37GB were installed. After digging Google for a bit, I couldn't find anything helpful, but I do remember reading a post in a forum regarding the motherboard using 640MB of RAM. Digging in my own BIOS, I've also found that my motherboard has also reserved that amount for its self. Why does my motherboard reserve this memory and how can I tune it down to say 128MB?

  • What are these? Are they broken?

    - by Chris Nielsen
    Please excuse the poor image quality: What are the components that I've circled in red? The ones on the left look whole and solid. The ones on the right have cracked tops, and although this picture doesn't show it, there are small brown threads coming out of the top. Are the cracked ones broken, or is that supposed to happen? If they ARE broken, is this something I should worry about? This is a video card, and it appears to be fully functional: I'm using it while writing this post.

  • Problem with usb wireless mouse

    - by aiacet
    Recently I have started having problems with my wireless mouse (Wireless Optical Mouse MI-4910D). Sometimes when I start my PC or during a game the pointer/arrow stops moving. When the PC boots the pointer is locked in the center of the screen. If I'm lucky it helps to change the USB wireless adapter from port 1 to port 2 but sometimes this trick doesn't work and I have to restart my PC to get the mouse to work again. Like you can see in the product web page this mouse don't have a driver but only a tool to solve some problems. Thank you in advance to all the "super-users" that reading this question would be help me Ajax

  • Anybody makes stylish PC cases that look like the Cobalt Cube?

    - by OverTheRainbow
    Hello I'm looking for computer cases that don't look like regular PC's in case customers would like to keep it on their desktop so it has to look stylish. I liked the Cobalt Cube: http://en.wikipedia.org/wiki/Cobalt_Qube Does someone know if some company makes cases that look the same (I know about Shuttle : they're too pricey), and possibly one that has a really quiet power supply? Thank you.

  • Advice on Computer Specs for overall development/general use machine

    - by Ender
    At the moment I am restricted to a laptop with 512MB of RAM, a 120GB HDD and a 1.5GHz Intel processor for all my development and general browsing needs, and as you can probably tell using it for anything modern is a painful experience. As a result I've decided to buy myself a new desktop computer, one that will stand the test of time and one that can be upgraded easily. Rather than build the machine myself I've decided to go through Dell as I've had good experiences with them when purchasing computers for my family. I've had my eye on this as it's got a good amount of RAM, has a decent-rated processor and isn't priced too badly. http://www1.euro.dell.com/uk/en/home/Desktops/inspiron-580/pd.aspx?refid=inspiron-580&s=dhs&cs=ukepp1&~oid=uk~en~20211~inspiron-580_d005827~~ Intel® Core™ i5 Processor 750 (2.66GHz, 8MB) Genuine Windows® 7 Home Premium 64bit - English Display Not Included ATI Radeon™ HD 5450 1GB DDR3 graphics 6144MB Dual Channel DDR3 [3x2048] Memory 1TB (7200rpm) SATA Hard Drive DVD +/- RW Drive (read/write CD & DVD) with DVD Burn software 1 year of coverage included with your PC McAfee® Security Centre - 15 Month Protection - English After the pain of using a slow laptop for all this time the main thing I want is speed. I may look to play a couple of basic games on it, nothing too powerful. Obviously I'll be doing some development on it too so it'll have to be able to handle the latest IDE's and Database tools like SQL Server pretty quickly. Finally, should I ever need to improve it I'd like to be able to add more RAM and change some of the parts. I wouldn't have thought this would be a problem but a few people I've spoken to have said that the amount of RAM the motherboard can handle isn't that great. Is this true? How long can I expect to be using this computer before it's too slow? Thanks in advance for the help.

  • How can I read a reel-to-reel tape from the 1970s?

    - by Joe Wreschnig
    A close friend of my mother worked at DEC in the 1970s and 1980s. She recently passed away, and in sorting through her estate, my mother discovered some reel-to-reel magnetic tape. We are curious about what might be on it. I haven't yet seen a picture of it, but Wikipedia tells me this is most likely DECtape. Is there any chance the data on it is still good? It was not preserved with great care, but as far as we know it has also never been particularly abused. Just left in a box and moved a few times. If the data is still valid, do we need to dig up a PDP or VAX or read it, or is there a more modern option?

  • How can I obtain/build a wireless volume knob for Windows?

    - by Mr Grieves
    I use my computer as a media center and simply love it. It's an older box running XP and it works better than everything else I've tried turning into a media center (Windows 7, Vista, several Linux distros, etc). The only thing I hate is having to walk to my audio amp to turn the volume up or down. I can use the Windows volume slider or any keyboard with keys to control volume. What I'd really love is to have a wireless knob which I can put anywhere when listening to music (e.g. kitchen) which controls the volume. It seems so simple yet I can't find it anywhere. Having controls for pausing and moving to next song would also be terrific. Griffin's Powermate could do the trick but I'd really want it to be wireless. Do you know of something I can buy or build myself to serve this purpose?

  • Data recovery on an Iomega portable drive.

    - by Kaji
    For Christmas, my little brother got an Iomega 500GB portable hard drive. It'd been working well, but last week it flat died, and the company's trying to shirk it, claiming it's not under warranty and saying it'll cost at least $900 to recover the data from the drive. He's still trying to fight the warranty thing, but wants to know, should it boil down to it, what other options exist for recovering the data from the drive. (in before "BACK UP!")

  • How would you diagnose an integrated network card that doesn't show up on the device list?

    - by Tomer Gabel
    I've been setting up a server based around a Gigabyte GA-G33M-DS2R motherboard (G33, PCH9R with integrated Realtek 811B network device. I've enabled it in the BIOS, but it doesn't show up in the pre-boot PCI device list, isn't recognized by Windows (even after installing the chipset and networking drivers) and doesn't even show up via lspci. I've tried cycling power, disabling, cycling again, enabling, cycling again etc. to no avail. I'm sort of at a loss at this point; the board isn't under warranty anymore, but I'd rather not have to replace it. Any advice would be greatly appreciated...

  • PC reboots spontaenously: debugging tips

    - by aaron
    I swapped my core 2 duo for a quad core recently, and generally things run fine, but every now and then my computer just restarts. I don't even get a blue screen (Vista 32). Core temp isn't a problem. My thinking is that my power supply is inadequate, but I haven't been able to test that (one idea was to under clock the cpu to see if that helped, but going up in speed was the only simple thing to do in the BIOS) Two cases where I semi-consistanly get problems: - Borderlands windowed after some period of time (and some other games, but Borderlands does it pretty regularly) - watching a video (e.g. quicktime/vlc) and having another video running Another thought is non-cpu heat? Maybe the graphics card? Any thoughts on how to track this down appreciated. Thanks!
