laptop shuts down by itself

The laptop i am trying to fix always loses power after being on for 40-100 seconds.  Sometimes it won't even boot all the way.


The only blue screen I have managed to record was stop error 0x00000402 which the internet says is RAM related.


I ran Memtest86 and it loses power at 1% of the test (with no errors).


There is only one stick of ram so I wonder if it is faulty but I don't have another to check with.


I have replaced the cmos battery, even opened her up to look for hot spots.  


Even with the hard drive uninstalled I still can't boot to cd.


I suspect the heatsink for the processor as the laptop is old but there are a lot of things in the way secured by torx bolts (thanks hp).


Can anyone offer any helpful advice?
