I just got a new system upgrade in terms of hardware. Configuration: Gigabyte 880GM-USB3 motherboard AMD Phenom II X2 550 DDR3 2 GB RAM Two HDDs: Samsung 40 GB (IDE channel zero master) Seagate 1TB (IDE chnnel 3 master) Note: XP boots from Seagate On board ATI Radeon 4250 Graphics OS: Windows XP SP3 New system: Put into place on 9th October 2010 Except Samsung 40 GB HDD everything is new. Problem: 1) It has happened that while using my computer for a long while, it shuts down suddenly and restarts spontaneously. This has happened especially while playing Age of Empires III PC game. This spontaneous shutdown must have happened about 3-4 times till date, as much as I can remember. 2)Today, that is 5th November 2010, I got a blue screen of death with the following technical message STOP 0x0000000 (0xFFFA0080 0X000000FF 0X000000001 0X806E6F27) This BSOD, happened while I was watching a feature film on Windows Media Player with my family and my dad's really worried why this happened. Then I restarted the PC after noting down this message. Please help me diagnose the problem I am facing and how to solve this problem. Thank you all.
