This is kind of a weird problem, so I hope I will find the answers I need
Anyways, here goes. I recently upgraded my PC (bought a new mobo, CPU and ram) which are the Asus M2N-E, AMD x2 4600+ and OCZ PC6400 DDR2 ram. When everything was installed properly, I noticed that when I was in Windows my PC would freeze (hard lock) at random times and I was forced to reboot.
Let me backtrack for a second. With my previous PC before I upgraded, this happened IN-GAME maybe 3 or 4 times max (and by this I mean the hard-lock freezing). This happened before I upgraded too.
I've had this new PC for about a month now, and I'm still experiencing these freezing problems however they do not occur in-game, they happen in Windows. I find it happens a lot if I'm downloading with Firefox and multi-tasking (weird).
Within the past few weeks, I've noticed when I exit out of Quake (yes, the original Quake) my PC will freeze for mabe 5-10 seconds and I will either see vertical lines of gray and white, or just a scrambled red screen. I know this could be because of the video card.
My question is, can the video card also cause these random Windows freezes? Any help would be MUCH appreciated.
And it is NOT temperature related! I checked and all the temps are perfect!
Chances are a Video card failure wouldn't freeze Windows (Might freeze Vista, as it is so Video heavy), it would simply knock out your screen. You might get a blue screen, but I wouldn't think the video card could freeze an OS that doesn't need one.
What's your Power supply (PSU) and Hard drive situation?
If you aren't getting enough power to a drive, it could fail on you, resulting in weird glitches, depending on how many system files are stored on it.
First thing: Tell us more info about your PC (Hard drives? Type and number. PSU? Wattage and brand.)
If you can get video out of your motherboard (I'm not sure you can), try not using the Video card (IE: Unplug it!)
Quake glitching up could be because of your refresh rate on your monitor not syncing with Windows/NVidia control center, or due to messed up resolutions.
Logical2u: Thanks for the quick reply.
My PSU is an Antec Truecolor 2.0 480W, so I don't think it could really be a power issue - but then again maybe it could?
Hard drive is a Western Digital Caviar WD2500KS 250GB.
the_irish_fly: It's not my RAM because I ran memtest and came back with 0 errors.
