Two days ago I started to have Windows XP boot problems. The next morning It wouldn't boot up at all. I switched the boot sequence to the other HD which has Windows 7 on it. It booted once. The next time it wouldn't boot. I checked the BIOS and found the following wasn't recognized: 2nd core in the processor, both serial HD's(both IDE DVD drives were shown).
I think I have a MB problem but what else could cause these problems???
