Hello everyone. i have had a problem that has plagued me for months now, and I have spent a lot of time troubleshooting different parts of my PC.
Here's my basic stats:
Mobo: Ausus P5k pro
CPU: Q6600
GPU: 512MB Radeon 4870
HDD: 750 GB WD
RAM: 2x2GB OCZ
PSU: Corsair TX 650
The problem:
For the past few months I have had a problem that occurs regularly. I will be gaming happily along, and I will have several problems occur:
1. Artifacts going across the screen. Alt tabbing will usually fix this, but then
2. Game screen will freeze, PC will lock up, a buzzing noise occurs through the speakers, my monitor goes into sleep mode. Then it turns on and it is a BSOD ati.kmdag. problem.
Sometimes the screen will freeze without the artifacts first happening. It also can happen when i am not even in a game.
I believe I have extensively troubleshooted the problems. Here are the things that I have tested for and have become satisfied that it is not the issue:
1. Overheating. For the longest time I thought this was the problem. However, once I started upping my fan speed and paying close attention to my GPU temp, it is not the problem. Also, it can effect a game soon after being loaded up or after playing for an hour or two.
2. GPU in general. I thought it was the problem so I recently RMA'd it. Visiontek was nice enough to send me a new 4870, and it has had the same problem. I have tried different Catalyst drivers and none of them seem to work.
3. RAM: I thought RAM was the problem as well for a while. However, my two sticks ran fine in my brother's PC and they passed memtest. (There may be one issue here: I ran with only one RAM stick for a while after reading that this may cause a crash, and I don't remember having any crashes occurring during that period. I don't know if that is significant or not, but remember that they passed memtest and ran in another PC fine).
I believe I have narrowed it down to either my PSU or my motherboard. Today I tried my new videocard in my secondary PCI- express slot and it also had the same problem. In a bout of insanity I tried another power cable for my PSU and it didn't matter.
If any of you are willing to try to help me, I will be happy to answer any questions or do anything that will help resolve the issue.
Thanks in advance!
