I've been having trouble with one of my machines where it will periodically shutdown during the boot process. Sometimes it happens and other times it is fine. Lately, I haven't been able to get it to fully boot at all. it seems like it shuts down at almost the same point each time.
Things I've tried: -memtest and swap out memory for new memory -try different slots for memory -remove video card and use integrated video card -remove dvd burner -reinstall OS (Windows 7) -install alternate OS (Windows XP and Ubuntu -- same issue happens)
The only thing left that I can think of would be a bad motherboard and/or CPU... Has anyone experienced any similar issues?
