Can anyone give any advice? I can't load or run windows xp with the intel core2duo e6750 proc in dual core mode. I am using the E6750 with the intel DG33TL board. When loading XP pro I get to the point when XP is setting up at the blue screen with the progress bar and 39 min till setup is complete,the progress bar shows "installing devices", the download stops with blue screen IRQL_NOT_LESS_OR_EQUAL 0x0000000a. To load XP Pro (svc pack 1) I had to enter BIOS and disable the secondary core for the processor. I am then able to load XP fine. Once XP was loaded I did not load service pack 2, but went back to the bios and enabled the secondary core. Windows loaded one time then downloaded an update because it detected new hardware then restarted. I was then unable to load XP upon restart even after disable or the secondary core again. I had to reload XP with the secondary core disabled to get the computer up again. I now have service pack 2 loaded but I am afraid to enable the other core unless I can come across what could be a definite fix or patch. Got no help from intel or microsoft. Ideas anyone? Thanks
