I've recently upgraded to a 1TB HDD in my custom built computer and had to reinstall all of the drivers. Most of the parts in my computer are approx. 2 years old and I used the drivers that came with the Asus M2N-E motherboard support CD and the EVGA video card support CD. Everything seemed to go fine until I started stressing the comp with high graphics video games.. I'm a World of Warcraft player For no reason at all it seemed I started getting application errors during use of the game and then most of the time those errors would lead to blue screens. I don't have these problems during typical use of the computer, i.e. using a web browser, playing music, etc. So, being the low income vide-ette that I am, I set out to try and find the cause of the problem in the endless vastness of google. Well thanks to the "guide to stop error messages" sticky on this thread, I found a page that I think let me know what my problem was. Before I found this site though I had read numerous pages about how to determine what the stop message codes were and how to read them but, of course, nothing that told me explicitly and I'm still not 100% sure and am in need of some advice. So.. with the aumha.org/a/stop.htm website, I determined that the stop message 0x00000050 usually references defective memory or imcompatible software (i.e. device drivers, right?) and the stop message 0x0000008E usually references hardware compatibility and sometimes driver issues... if I'm understanding the above website correctly. Well I had been using these computer parts for months w/o fault before I reformatted onto the new HDD so I find it hard to believe it's a hardware compatibility issue.. this leads me to believe it's either a video card RAM issue, a main RAM issue or a device driver issue. I'm leaning towards the drivers being either corrupted or out of date and I'm wondering if anyone can tell me if that's a safe assumption. I'm setting out to update everything and it would also be much appreciated if someone can tell me if there's anything I'm missing (or shouldn't mess with) on this list... 1. nvidia nforce 570 ultra chipset drivers 2. EVGA geforce 8800 GT 512 MB video card driver 3. SoundMax audio driver 4. AMD athlon 64 x2 processor driver 5. I've also made sure I've downloaded all windows updates for win xp 2000 32-bit I'll update with any changes once I've done this and whether or not the issues continue... if updating the drivers doesn't help, then I'm thinking I have to replace either the video card or the computer RAM.. any opinions on that assumption?
