BSOD on desktop appearing after two previous crashes

Also do uninstall AVG as they were part of some of the BSOD....

Install MSE instead

There are lots and lots of errors (over 25000) (i.e. there is a large red rectangle at the bottom of memtest), but it hasn't stopped (it's on test 5) - are minor errors normal or should I retry with one stick of RAM?

EDIT: Further oddities. After putting one stick of RAM in boots, but nothing comes up on the monitor? This seems very strange, and I would imagine indicates something wrong with the graphics card, but its fan is still spinning happily?

if you found errors... one of the RAM slot or RAM stick is having problem....

How many sticks of RAM do you have ??

Update your specs .... I am shooting in the dark

here use this to update it

I have three, which I know is a bit awkward. Do you think it couldbe a graphics card issue?

EDIT: After reseating the GFX card and testing the RAM individually, it was a dodgy RAM card causing the problem. Many thanks for your swift help.
