I've been wracking my brain trying to figure this out. I've googled the error, tested my RAM run a billion Virus and Malware scans...I'm still unable to figure out what is causing it. I'm getting a blue screen and STOP: 0x0000008E (0xC0000005, 0xAD6259D9, 0xAA40212C, 0x00000000) It seems to occur most frequently when I try to sign into Windows Live Messenger. But It has occurred at other times. I am on Windows XP Home SP3 If it's a hardware issue...I'll list that stuff below CPU: AMD Athlon 64 X2 6000+ GPU: Visiontek ATI Radeon X1950 Pro XGE PSU: Antec TruePower Trio 550 RAM: 1GB Corsair XMS2 DDR2 800MHZ "CM2X1024-6400" (I had 2 GB but one stick went south on me a few months back) HDD: Seagate Barracuda 160 GB SATA Internal Hard Drive Any help would be appriciated! Thanks!
