I just made my new computer with all good hardware. my problem is that one of my memory sticks might be bad..it surprises me because i got Corsair XMS Extreme Memory Speed Series that stuff is usually good..i got a DFI "LANPARTY UT nF4 Ultra-D so really didnt think ne problems should occur.i dont know if it is because i dont have it in dual channel or not.i said to put it into the 2 & 4 slots..when i did i was installing xp professional first it was verfying dmi data pool...changed the boot order...then it worked then before install the windows it had the blue screen of death...and was IRQL_NOT_LESS_OR_EQUAL idk something like that took out the memory and it when through..i thionk i have all the drivers updated..so im pretty much stuck..i put the memory in again and would restart right after booting windows. sorry for being so long
