Oh Crap!!

Afetr running really well for a number of days, yesterday, my PC rebooted in mid use, and on powering back up - Invalid Boot device etc.!

After several failed attempts to reboot, removal of the 2nd SATA HDD, removal of the ATA DVD ROM drive - still nothing... Then Bang/Flash/Smell of burning.

I am assuming that the power supply is the problem, and will replace it today with one from PC World - I just hope no damage has been done to the Motherboard :-(
