Hi, I have a very severe issue in my PC. My specs are: Motherboard - Asus A7N8X Deluxe CPU - AMD 2100 HD - 1x 20 gigs IBM IDE 133, 1x 80 gigs Maxtor SATA Video Card - Nvidia Gforce 4 MX 440 Ram - 2x 256 MB DDR 333 I'm running Windows XP and having some problems. For the last 3-4 months Windows XP keeps giving me almost all kinds of BSOD. I think I ran into almost any BSOD exsist. The ones who are repeating on a daily basis are: 0x00000050 0x0000008E 0x0000000A 0x0000001E 0x0000001A 0x000000C2 0xC000021A The strange thing is that it's completely coincidental. The system can work for 2 hours without any problem, and then opening a word document, or checking mail or anything else can cause BSOD. In other cases after a minute that system is up, I get the BSOD. I've tried testing the memory with at least 3 different programs(including memtest86), no error found. Tried working with each of the memory cards seperately and still same BSODs. I've updated the BIOS to the latest one, didn't help. Updated the video card driver. Checked for a heating problem - not the case. As a last resort I tried installing Windows XP again, and those same BSOD are repeating in the Windows XP Setup! Any ideas what could be the cause? Any ideas what's the next stage?
