Hi I'm new to these forums, found them after quite a few bsod's over the last couple of months, I'm starting to pull my hair out with this one

. I was looking to debug this myself but none of the symbol libraries seem to work

.
I have had this issue a while now, even had new equipment at work.
Now got i5 650, asus p7-h55 m pro, 4gb ram, 160gb hdd, 450w psu.
I have attached the minidump file.
Please help, I'm going to run memtest over night see if the ram is a problem.
