I have an Asus 9800XT graphics card with the latest ATI drivers. I installed extra software to display the temperature of the CPU, motherboard, and graphics card, (along with voltages and such.) No overheating was present anywhere, and all voltages are nominal. I replaced the graphics card with an old 64mb Nvidia Ti3(something). No more pixellation or artifacting, but instead the screen will go blank for a second or two and will return to normal, there shortly after, the computer usually freezes or crashes.
Thereafter, I began running AdAware and Spybot S&D to see if it was software, nothing was found. I am trying to run TrendMicro's House Call virus scanner but have had no luck. I cannot keep the computer from freezing before the hour and a half virus scan completes. I have been leaning towards hardware, rather than software because I get the same symptoms even in safe mode.
Normally, when my computer shuts down, it makes a clicking noise from either the motherboard, or one of the three hard drive's magnetic heads returning to its home position. When my computer crashes, it makes the same noise, like it is trying to shut down. Strangely enough, the hard drive usage light on the front of my case becomes solid after a crash. Possibly a hard drive issue...?
Just a few minutes ago, it sounded as if my computer got quieter, my computer lights (cold cathodes) seemed to dim a little bit. Then as I looked into the computer window, I heard that click noise again and the fans seemed to speed back up and the lights returned to normal.
I have been removing pieces from my computer, one at a time trying to diagnose the problem. All that is left is my primary hard drive, old Nvidia graphics card, motherboard, and RAM. The only thing it can be is either software or hardware on the hard drive, the ram, or the motherboard.
I have a HijackThis log ready to go if needed.
Please help! Thanks, Jean-Pierre.
