Default Graphics Artifacts Hi guys, I've been having this problem for almost a year now, it's driving me absolutely crazy. All games I try to play have huge amounts of textures artifacting all over the screen, I've tried several things to fix it. To start with I thought maybe my PSU wasn't powerful enough to support my video card at the time (Radeon X1950 AGP), so I purchased a new Power Supply and case. The power supply didn't fix the problem, so I decided my video card must be damaged. I've spent a long time saving for a card and finally today got a Radeon 4870 (PCI-E), much to my dismay, I'm still experiencing artifacts. I read that it could possibly be my RAM (2x 1gb Generic Kingston DDR2), so I ran a RAM test recommended by another site, my RAM passed the test without any errors. My case is a Soprano DX with stock cooling, but I experienced the same artifacts in my previous case also. My CPU is just one of the lower Intel Dual Cores, an E4400, I think it was. I've come to the conclusion that it must be either my motherboard or my PSU still, as the PSU is only a budget one and I'm not sure if it's powerful enough, it's specs are - Brand: Shaw 600w +12v = 30a +5v = 50a +3.3v = 35a -5v = 0.5a -12v = 0.5a +5vsb = 3.5a My motherboard is a Asrock 4CoreDual-VSTA, I got it because at the time I needed AGP and planned to upgrade to PCI-E. I'm not even sure if it's possible for a motherboard to cause artifacts, especially since I was originally using the AGP port and now it's the PCI-E. It might also be worth noting that I'm running IDE hard drives at the moment, if that makes any difference. I'd really like to be sure of what's causing the problem, as I can't afford to keep replacing parts till I find the problem, any advice you guys could give would be hugely appreciated! Regards, Kamma EDIT: After testing a few games, it seems that the artifacts are actually worse with the new card. Does this suggest that it's more likely to be the power supply? Given that the new card needs more power.
