Hi all, i have an Acer Aspire 5630 laptop. I have had a problem for over a year now with it randomly crashing. I have reinstalled XP, Vista and windows 7 but it seems to happen in all versions. So this leads me to believe it is a hardware fault.

I have tested a brand new hard drive and ran seatools over the top of my original hard drive with no errors, the laptop still crashed.
I have ordered brandnew Kingston memory for the laptop... it still crashed.
I updated the BIOS to the latest version from the Acer website and again, it crashed shortly after.

I have stripped the laptop and cleaned the cooling unit and repasted the CPU and graphics chip and it is still crashing.


Something interesting though, when i try to run any DOS based memory test, the computer instantly locks up, this includes windows memory diagnostics in windows 7.


Ideas??
