New PC - Occasional blue screen

[5./JG27.Farber]

No wolf rider.

OK I took one stick of ramm out, PC booted ok. So I put the other stick in on its on and got loads of errors on start up...

So I took the ram back to the shop and they exchanged it. Came home, put the new ramm in with the "good" old one and it BSOD'd before it even booted.

Took it out, booted...

I think my OS might now be corrupt so I guess I will once again have to format the HD
