Starting a couple months ago when I start playing a game, or anything that seems to use a lot of computer resources my peripherals turn off then back on constantly and sometimes just turn off altogether. Each time it does it both of them go at the same time, my mouse comes back fairly quickly but the keyboard takes a good 15 seconds usually to boot up again. It happens somewhat randomly but very frequently making games unplayable. This rarley/almost never happens just in windows or on the internet but i cant do anything else! I took apart the machine to dust/check connections/wiggle wires/etc and afterwards my machine would not turn on at all, and after some more tampering it turned on but would not recognize the hard drives, then after some more it turns on just fine like it used to but same mouse/keyboard problems during games.
The problem will occur in all enviroments such as right after booted up, been running all day, etc. I replaced the graphix card because it was an upgrade i had already planned to do and already ordered on the way before the problem started happening and the card is more energy efficient and the problem went away for a week then came back. Also this whole thing started more slowly moths ago but now is unbearable.In the list below I will list the things i have done to try and fix it so far.
What i have tested so far:
-Tried other peripherals, same problem with them.
-Uninstalled/re-installed and updated all peripheral drivers and software
-Formatted hard drive/ re-installed windows and reinstalled all drivers from scratch.
-I tried it with non of the logitech software installed.
-I Updated all the motherboard drivers
-Took apart maching and inspected connections.
-Dusted the internals with the air duster thing.
-left psu off (switch in the back) for days and turned it back on.
-I have all virus programs running such as comodo/avast/malware bytes, all updated, no viruses at all.
-I tried plugging the computer directly into the wall.
-All the fans are running.
-I did not update the bios cause last time I screwed up my computer
My machine specs:
-About 4 years old
-Windows xp pro 32 bit
-Intel Core2 duo 2.4 GHz
-2 gig RAM (cannot remember the exact type)
-Logitech G15 keyboard (older blue light one)
-Logitech M518 optical mouse
-Asus P5B-E Motherboard
-Antec phantom 500w power supply
-Current video card: eVGA e-GeForce GT220 1GB DDR3
-Old Video Card: Asus Radeon 3870
Anyways, i am fresh of the windows restart still the same results and I am at a loss! If anyone could help me I would appreciate it. I was this close to buying a new psu but I really dont want to pour money into this machine if I dont have to as I plan on building a new rig sometime in 2011.
