Worked for 3.5 hours with no problems. I did some word processing, internet surfing, video watching, and played a game. Then I left it for about 20 to 30 min came back and it had died and restarted.
I dont get it.
Defective memory, memory incorrectly installed or mismatched memory sticks
BIOS having the wrong settings and/or overclocking the processor (CPU) or memory
Stopped or slow fans causing overheating
Defective or buggy hardware or video drivers
Defective Processor (CPU)
I have extensively checked the memory with memtest, so I think we can rule that out.
It is not over clocked so I think that can be ruled out
It runs at a constant 70 deg. F to 90F depending on load
I have installed different versions of the video drivers, and totally disabled it and ran on the on-board memory and it didnt help.
so I guess that leaves a defective processor. how do I check that?
