Computer Randomly Turns on From Sleep

I only saw this thread now, otherwise I would have suggested this sooner.

PC Randomly Restarting after installing new Ram!

Tried your suggestions, but still had a restart! Also ran memtest overnight (13 hours according to memtest) and had no errors! Also ran Passmark Burn in test for a couple hours testing everything and had no errors or restart. Could fitting the new ram have triggered something to go bad like my mobo or psu?
