Back in November I replaced the motherboard in my pc, However ever since then I have had to shut it down and then switch it off at the mains. Otherwise a few seconds after everything stops (fans stop, Hard disks spin down etc) The pc restarts. Now I have tried everything from my 8 years of PC Support knowledge and can’t find a fix. Which means I know have to take the motherboard out, box it up and send it back to

I’m “umming and arring” other a number of choices. Do I scrap this pc – As its 3 years old this month, and build a brand new machine Or do I replace the motherboard like for like. Well before I can make that decision I need to get off my arse and take the motherboard out the case anyway!
