  • Which type of motherboard i should by and why?

    - by metal gear solid
    If budged is not matter. I just need best performance with less power consumption. I can purchase any cabinet , power supply and Motherboard. Is Power supply has any relation with Form factor? Is the size of motherboard and number of Slots only difference between all form factors? Is there any difference related to performance of motherboard? Is bigger in Size (ATX) motherboard always better?

  • Why does the heat production increase as the clockrate of a CPU increases?

    - by Nils
    This is probably a bit off-topic, but the whole multi-core debate got me thinking. It's much easier to produce two cores (in one package) then speeding up one core by a factor of two. Why exactly is this? I googled a bit, but found mostly very imprecise answers from over clocking boards which do not explain the underlying Physics. The voltage seems to have the most impact (quadratic), but do I need to run a CPU at higher voltage if I want a faster clock rate? Also I like to know why exactly (and how much) heat a semiconductor circuit produces when it runs at a certain clock speed.

  • Low end dedicated GPU vs. integrated Intel graphics (for light CAD work)

    - by PaulJ
    I have been asked to spec a PC for an interior design business. They are going to do some AutoCAD work (but they won't be using massive datasets or anything), and also use Kitchen Draw, a program that has 3D visualization features and says, in its requirements, that "a recent NVidia or ATI card might be enough". Since they are very limited budget-wise, I had originally picked a GeForce GT 610 card, but this card is so low end that I'm left wondering whether it will be an improvement at all over the dedicated Intel HD2500 graphics chip that comes with the CPU (I will be using an Ivy-Bridge Intel i5). Most of the information I see around is for gaming, which isn't really relevant in my case. Basically, for the use case I've described (light 3D work), can one get away with a current Intel HD graphics chipset? And will a low end GPU like the GT 610 provide a noticeable improvement?

  • Which type of memory is faster than average for server use?

    - by Tony_Henrich
    I am building a server computer which will be used for SQL Server and I am planning to use like 32G+ of RAM and putting the databases in memory. (I know all about data loss issues when power is gone). I haven't been up to date with the new types of memory sticks out there. What kind of memory should I get which is faster than average and not very expensive? I am buying a lot of ram so I am looking for memory that's above average but below high end if high end is very expensive. (I will be using Windows Server 2008 R2 Standard or Windows HPC Server 2008 R2)

  • Tool to test HDD for health?

    - by Ognjen
    I've had my HDD replaced, and now my computer is freezing every 1 to 5 minutes for 5 to 10 seconds. Actually, only active applications freeze (but it can be ANY application), usually when I click something, but sometimes by themselves. How can I check if this is HDD issue or software issue? I don't want to send my laptop for second HDD replacement right away, since the last service took 40 days, so I am looking for a tool that could confirm that this is a HDD issue.

  • What's a worthwhile test for a new HD?

    - by Michael Kohne
    I work for a company that uses standard 2.5" SATA HD's in our product. We presently test them by running the Linux 'badblocks -w' command on them when we get them - but they are 160 gig drives, so that takes like 5 hours (we boot parted magic onto a PC to do the scan). We don't actually build that many systems at a time, so this doable, but seriously annoying. Is there any research or anecdotal evidence on what a good incoming test for a hard drive should be? I'm thinking that we should just wipe them with all zeros, write out our image, and do a full drive read back. That would end up being only about 1 hour 45 minutes total. Given that drives do block remapping on their own, would what I've proposed show up any infant mortality just as well as running badblocks?

  • I don't have a free PCI / PCI-e slot, can it be worked around?

    - by Borek
    I need to add a PCI(e) card to a nettop PC that is so small that the card won't fit there (and there is no external alternative like we're used to with external TV tuners). The only ports available are USB and eSATA, is it possible to somehow "dock" the PCI card into some device that would then connect to the PC via USB or eSATA? Or am I out of luck? (I don't mind the solution being visually ugly, I wouldn't even mind opening up the case and soldering some wires in, anything that would work would be great.)

  • Find the model of my motherboard without opening the computer [closed]

    - by Code
    Possible Duplicate: Find out what the motherboard on my computer is I need to find the model of my motherboard so I can find what soundcard/chip it uses so I can get some drivers for it. Is there anyway to get this from inside XP? I looked through device manager but haven't seen anything that would tell me. I built the system over a year ago and don't have any receipts to check what it was.

  • Multi mouse, keyboard and monitors

    - by Click Ok
    I've got a USB hub with 4 ports, and I've plugged 2 usb keyboards and 2 usb mouses. They work very fine. I've setup'ed 2 monitors too, so I was thinking about the possibility of the mouse and keyboards works independent one of another. I want two mouse pointers (I think each with different colors) and 2 keyboard cursors. I think it a nice idea, but I don't know if this is possible... :( PS: My OS is Windows7

  • Computer restarts infinitely after Bios/Motherboard screen

    - by user13176
    Like every morning I turn on my computer (which is kinda new and only couple months old) and I never had any issue with it until now. It starts booting, shows that very first screen which has some motherboard picture and stuff and then it show which buttons to press to enter BIOS and etc. Then it suddenly restarted and after that just kept restarting every 3-5 seconds forever. What could that be? I unplugged power cable, checked all the cables, moved a case, it had some wires stuck under it, blew some dust (but didn't open the case yet) and I tried to boot again and it booted successfully and I am writing this issue now. My specs: i3-3220 3.30Ghz 8GB DDR3 RAM 1TB HDD GeForce GTX 650 Windows 8 x64 I also recently upgraded my security software (that's the most recent thing I did) and it includes ZoneAlarm firewall, Comodo Antivirus and Spybot Search & Destroy. But maybe it doesn't have anything to do with this. Cheers

  • Why does using 2 memory sticks cause my computer to crash?

    - by hi
    My computer randomly crashes when playing games, but if I remove one memory stick (it does not matter which one I remove), it does not crash anymore. Memory tests do not find errors, I just put in a new power supply (650W), I only have 1 graphics card, so why is this happening? BTW, they are the same memory, same vendor same specs, everything I bought it together (2x2GB) My motherboard is a Asus P5Q Pro, so it supports both dual channel and more than 4gb. Switching slots does nothing, as long as I don't use more than 1 I'm fine.

  • Web server HW requirements [closed]

    - by Kimo
    Hello, I am trying to search for a book that would teach me how to choose web server HW requirements (hard disk space/technology, ram, internet connection) based on web site statistics (requests per second, etc...), how to scale webservers in case my website is getter higher traffic, etc All I get from the internet is software-related articles. Does anyone know how I can dig in for this kind of information? May be I am just searching using the wrong keywords. Thanks

  • 1 Computer Pulls Wrong DNS Every Morning

    - by bradenkeith
    One of my users takes his laptop home, connects to his internal network fine. He brings it in every morning and since Monday - every morning it pulls the wrong DNS every time. It pulls 1 DNS: 192.168.1.1 which is the router. The DNS are external IPs. I have several users that take their laptops home and connect to other networks - what could cause this anomaly? He's booting up when he comes in the office and a simple ipconfig /release /renew fixes the issue.

  • DVD Drive Has Stopped Recognizing Discs

    - by ricree
    My DVD drive no longer recognizes dvds, but does recognize CD-ROMs. When a DVD is in the drive, the computer continues to act as though there is no disc in the drive. However, when a normal CD-ROM is in the drive, it appears to work normally. I have tested on several discs, both video and game, and the behavior is consistent. I have also tested this on both Windows Vista and Ubuntu 9.10, and the issue remains the same. Can anyone recommend a way to fix this?

  • Long term system health monitor

    - by user30336
    As an experienced user, I sometimes notice that things are not going well with my computer. For example, my backup drive recently started cycling up and down, so I guessed it was probably dying, and replaced it. I detected this with my ears. Windows did not seem to notice or care. There ought to be software that monitors overall system health by keeping track of things like this, so that unusual events or increasing error rates will not be shrugged off. Among other things: disk errors that are recovered, corrupt network packets (at above the baseline expected rate) and crashes of trusted programs are early warnings. Is there any software that tries to use this kind of monitoring to warn of impending trouble?
