Okay, so it's 3:37 in the morning this Monday night, and I've been up all night trying to fix this fucking computer. Last Friday, I bought this Sapphire X1800 XT 256MB PCI-E off of Dmans218 (member from another forum), and I installed it as soon as I got home, to try out with my Enermax Liberty 620W I had got the same week. When I first booted it up, I noticed weird green/pink-ish scan lines and artifacts on the screen between the BIOS splash menu, and the Windows XP loading screen. I didn't really think anything of it, and I continued using the card. Later on I noticed my 3DMarks and benchmarks weren't up to par, so I checked the card memory/core frequencies, instead of being at the default 625/750, they were at 600/700 (for 2D AND 3D), even ATi Tools showed 625/750 as the default. So I bumped up the frequencies to what they should be, simply by clicking 'Default Clocks' in ATi Tools, and the frequencies had gone up to 621 / 747, just what I had been looking for. Except now, I've been having ALOT of problems... I get more and more artifacts on the boot-up screens, and I can only get into Windows XP 1 out of 5 tries, usually it just hangs after the Windows loading screen. However, I can get into Safe mode just fine, and everything is pretty much viewed properly (except the artifacts/scanlines in between boot-up screens.) I've tried, uninstalling drivers, reinstalling new drivers, registry cleaning, all that jazz, and nothing seems to work. The only thing I haven't tried, is bringing it into a shop to get looked at and formatting, which should I do? Thanks!
