Computer Specs: Intel Pentium 4 2.8 ghz 1024mb (2x512mb) DDR400 PC3200 Corsair XMS RAM ATI Radeon 9800 Pro 128mb Thermaltake Purepower 420w PSU I have 3 hard-drives, one is SATA the other two are PATA Soundblaster Audigy 2 soundcard CD burner ============================================= This computer has been running stable for quite some time, although maybe 2-3 years ago my stock heatsink-fan on my graphics card died and I replaced it with a different one. Recently my computer has started developing artifacts on-screen. I've read that it could be the video card's processor or memory, or it could even be my RAM / PSU or bus? Anyways, I have a hard time believing it is an overheating issue. My video card heatsink-fan is attached firmly still and I removed all the dust from it. I also removed any and all dust from my cpu heatsink-fan as well, which is a 120mm zalman. CPU Fan: GFX Card Fan: Nothing is overclocked. I have a temp sensor placed on the copper pipe on the gfx card and its reading about 105-110 F when the problem occurs. I have tried opening the case and putting a desk fan blowing right on the card/cpu and the problem still occurs. Here is a picture of what happens: After a while the entire screen is completely unreadable and the system locks up (can't remote desktop in). One thing that slightly bothers me is the readings on a sensor read program: +3.3V: 2.94 V +5V: 5.03 V +12V: 12.00 V the 3.3 seems a bit too low? thats 10% off, and I read that it should be +/- 5% I first noticed this problem while playing a game, but now its been happening even while surfing the web. I am going to run memtest and a cpu strain test over the next two nights I am basically just looking for suggestions or personal experiences and what the problem turned out to be.
