Yes, I know this question has been asked here before but I can't add to the discussion over there and it did not help me, so here goes nothing.

I've bought an acer aspire 5742G about 2 months ago or so and it's been running great, but sometimes I used to hear the windows error beep but I had no idea what was causing it since the "bug" was automatically fixed so fast I couldn't even see an error message (also it kinda always happened when I was busy also, either in a game or while doing my homework).

Later on my mouse would simply not work for 3-5 seconds then work again, I thought nothing of it at the time. I also had a problem where it only worked in one usb and one only ... to move it I had to remove the battery, unplug the laptop and hold the power button for 2 minutes to reset the bios settings.

Since today though it went nuts ... sometimes it disconnects / reconnects 12 times in 10 seconds and windows just keeps beeping till I unplug it, then it runs smooth for 5-6 minutes then it goes nuts again. Other times it seems like it skips (disconnects for a fraction of a second) other times just for 2-3 seconds. But this is incredibly frustrating.

Sometimes the power just goes down (the laser turns off) and well that at least I would understand but this is a rare occurance.

Now I know the usb ports work since I have a lot of other devices connected and I tried the mouse on a room m8's laptop so the mouse also works.

My only conclusion is that it's an operating system / settings bug and / or problem (I have tried the mouse in all ports by the way).

All drivers and bios are up to date (maybe except mouse but i can't seem to update that and the mouse has no name, just a serial number which helps with nothing. Still it worked till today and nothing should have changed any way). I have made sure windows can't shut it down to save power (in device management).

Also I tried to delete the drivers and re-install them, rebooting and the power button trick but nothing ... most I have done is get rid of the 12 discconnects / reconnects every 10 seconds :) but that's all :(

I would buy a new one but I'm afraid it might do the same thing :|

****EDIT******

Tried the mouse again at a friend but now it didn't even install it's software nor did the update work ... think I'll just buy a new one but I'd still like a suggestion at least so I'll leave this open
