[QUOTE=eric93se;2589034]I would suspect the MB. Check all the capacitors on the board, the tops should all be nice and flat, any bulging would be a bad capacitor.[/QUOTE]
or they may have also vomited over the board!
I would be surprised that there is a problem with the capacitors as the board was manufactured when the BAD capacitors had been known about for some little while.
The cheapest option, and less time consuming is to replace the mother board with one that will take your current processor, memory etc. If however it is radically different don’t forget you will have to reinstall the os.
Best of luck.
