Semi-random BSOD on startup or within a few minutes of startup

[tetrisman01]

First off, this is a friends computer that I'm working on so I only have the information she has given me.
Essentially the computer will BSOD either during startup, or after a few minutes of using the computer. If it doesn't BSOD within a few minutes, the computer will run just fine until you turn it off.
I personally haven't seen the BSOD yet and have been working on the computer over the last couple of days.
I tried looking through the event viewer and it looks like it was x7f error when the computer was crashing.
Anyway, attached is the zip file, any help would be greatly appreciated, and sorry if I gave pretty shitty details on the problem.

Hello and welcome tetrisman mate there is a mention of memory corruption amongst soem of the manu blue screens

[COLOR="red"]BugCheck 1A[/COLOR], {5003, c0802000, 416, 2af02c}

Probably caused by :[COLOR="Red"] memory_corruption [/COLOR]( nt!MiAllocateWsle+6f )

So I think I would start with this RAM - Test with Memtest86+ this is the only memtest we recommend and MUST be run for at least 8 passes any less and you may as well not bother. Now best run overnight because it does take a long time but if errors come up fairly quickly then you can stop the test. Let us know how it goes.
