I recently reinstalled xp pro on my computer (QuadCore Intel Core 2 Quad Q9300, 2500 MHz (7.5 x 333); 4Gb ram)
and bought a new graphic card (HD radeon 5770 single slot). I was running Black ops fine, multi, single and zombies (with a nvidia 8800 Gt; low graphics) before i reinstalled xp and my new radeon HD 5770.
I have problems ever since. The game crashes radomly and message error like : fatal error / directx has encountered an unrecoverable error and some others appear. I've read that 0xc000012d problem is about memory; is it true?
My power supply is a 400 W and XFX (the card manufacturer) recommends a 500W power supply; could this be the problem? But most messages say that directx is the problem. Moreover, i've read that 5770 do not use a lot of power in 3D apps.
nb: all my drivers are up to date (Ati; directx; motherboard; sound chipset; network); i've cleaned with spybot s&d; ad-aware; checked register with tune up. I also tried former drivers for the graphic card et former directx. Nothing seems to work. I can only play BO multiplayer (working really fine), but no zombis, nor single player and no modern warfare II (sometimes for a few minutes and then crash / freeze. Ctrl+alt+del.
It's been 3 weeks now and i enjoy gaming so much that it makes me sad
My english isn't that good (french native speaker from switzerland) so please be lenient. Tell me if you need a log file of hijackthis, or everest (free) , or whatever. I'll take any advice from now on.
Thanks in advance for your help
