I once fixed exactly the same PC for my Uncle's girlfriend. Turned out the motherboard was forked, and I ended up going and getting them a new motherboard. I never found out what was wrong, but I did find out that flashing the BIOS made it worse. I wonder if you tried reflowing the solder on the NB/SB using a hot air gun/really hot hairdryer. Sometimes because they use lead free solder now, it doesn't flex with the temperature and can break away. Just a wild guess, but it could work. Good luck! |

My first thought was RAM, but since you checked that and all the other usual suspects I agree with Bally199 and suspect motherboard issues. |
