RAM problem?

I keep getting the blue screen of death and i contacted my pc provider about it, and they said it might be a RAM problem, i tried ringing them but no answer.
So im asking you guys, what problem do you think this is:

0x0000007F
DRIVER_IRQL_NOT_LESS_OR_EQUAL
0x0000000A
0x00000050

All the codes are the beginning ones.

Thanks!

Edit: I get this problem randomly, When im playing wars, or looking around on the internet.
