Hi there. I have been using this site loads and find it a valuable resource for all my computer needs, however now is my time to add to the ever evolving forum and lace a new thread willingly and ambitiously in the great weave of problems that need resolving. Like many other Windows operated machines out there, my one also Blue screens way too much. Ok, so i am on my machine playing Warcraft and it Stops giving me one of these many things i have written down so far. Bad_pool_header Driver_IRQL_not_less_or_equal Bugcode_USBdriver and at the bottom i have found on different occasions: USBbohci.sys USBport.sys dxg.sys I un installed Mcafee because i read in a few place that the Naiav driver can cause blue screen, then i cleaned the registry of all Mcafee entries. In the system event viewer, the ipod service came up as a fatal error so i un installed itunes. Still getting blue screen. My PC is well maintained and i take it for walks but it's HATES me and i don't know why haha Can i be the start of a new bluescreen solving quest? Thanks, i wait eagerly for a reply.
