Hello, This isnt my computer so I dont know too much about it. i know that it uses a intel server board and an intel xenon processor. It also has 4 gigs of ram. It has ISA server on it, symantec anti virus, exchange server, and mysql i think. Anyway about once a week the computer will blue screen of death and give irql not less or equal. Ive googled and found many answers but none match up with the parameters i get. I am attaching the minidump file and hope someone could help me out. My error code is 0x000000A(0xA000B674,0xD0000002,0x00000001,0x80835F35). I dont know what they have done to fix it. Dont know if they did memory tests on it or anything or checked other stuff maybe you guys will have something with this memory dump file.
