dual reboot problem

[peterkin]

I am running Fedora core 7, dual booting with XP (still trying to convert the family) on my good old Gigabyte KT 400 series Mobo with a Sempron 2500 processor. All good. On two occasions now, I have had reason to shut down Fedora and reboot into windows, and the reboot freezes just before it starts it's memory check. It then remains unbootable for about 1/2 hour, and then acts normally again. It seems to me like a Mobo/bios problem, but could it have anything to do with dual booting?

Check your memory modules. Also you may check the processor. Have a look at your hdd too.
The problem is not from dual booting! Sound more like a hardware problem.
