|For starters, you need to post the message EXACTLY as it appears. You're using O's where there should be zeros, you've added spaces where there should be none, you capitalized the X's, etc. The STOP message is probably closer to this:|
STOP: 0x000000F4 (Cx00000003, 0x870BE0B8, 0x870BE22C, 0x805C8D78)
Have you tried Safe Mode or Last Known Good Configuration?
