Hi all, I have recently updated win7 in MS and lost one of my quad cores??? I have tried going into msconfig and checking the number of processors to reset it but it's only showing three. I then tried uninstalling the processors from Device Manager in case it re-found them all again, No joy! I suspect it is an issue that Ms update has passed onto my bios but don't have the slightest clue what it maybe could someone please help me.
as in you lost 1 of 4 cores in your processor? if you go to task manager you only see 3 threads?
thats right only three of four working.
Uncheck the check box in MS config that says to use a certain number of processors, reboot and check again.
Also check in BIOS and confirm that it is reading you as a quad core still, i would also check with CPU-z and see if it thinks you lost one.
Hunter 315, thanks for your input on this, I had tried that but to no effect unfortunately in the end I took an old BIOS Flash and loaded it onto a DVD re-started going in to the BIOS and then flashed it then re-booted shut it down switched it off from the PSU switch unplugged it the power lead and re-booted, Job done, I had actually remembered that this has happened once before then i corrected it, thanks for your time. much appreciated
I have the same problem. I lost 2 cores of my 965BE and then another one went missing. Tried everything except re installing windows and flashing the BIOS. I googled and this has been happening since 2010. But MS update win7 every day or two, so I don't really think that caused it. But maybe it did.
I flashed the BIOS from 1101 t 1301 and the problem is gone. Awol cores are back where they belong.
