My system: FX 53 (939 pin) ABIT AV8 939PIN VIA K8T800 MB Window X-Blade 450W Visiontek Radeon X800 Pro 256 MB 2 x Kingston 512MB PC3200 PC400DDR AMD Thermaltake Athlon 64 3400+ 2 x Maxtor 200 GB SATA 150 7200 RPM 8MB HD Please help!! I bought this computer last year and it hasn't been working properly since, but company I bought it from (cyberpower) claims nothing is wrong with it. I bought it as a gaming pc and to run digital imaging programs, but it always crashes during games, and cant even import a CD without freezing. Very frustrating since it cost almost $3000. One concern is the power supply... 450w not enough? I downloaded the power monitor and it goes straight up to 100% when I try to import a CD. I've gotten advice that my PSU should be at least 530w to support fx53, radeon x800, etc. Other concern is the RAM. Is Kingston not a good brand for this system? I get blue screen errors, but when I do memory tests there are no errors. Also, on the AMD compatible RAM chart, the same type of RAM in the 256 and 1g versions are on list but not the 512 that I have. Weird? I'm looking to buy new RAM and I hear Corsair and OCZ are good, but they are also not on the list of Validated DDR DRAM Modules Which on the list are the best? I would appreciate help VERY MUCH! Thanks!
