[ This happened during the day when I thought I might have a problem with my PSU]
I had to remove one of my RAM sticks to get at the motherboard power cable. After checking that works, I rebooted my PC, but forgot to plug in the RAM again. Shut it down, put it back in and booted into the bios. I think I changed some settings around, and realised that there was no point ( changed to quiet mode) and then laoded up the optimised deafults. I then realsied that this would underfclock my RAM to 1333Mhz, not the specified 1600, so I went back in and OC'd it. Because Im an idiot , I clicked the wrong button and set it to 1800Mhz.
When I booted up with ram at 1800, I had a BSOD, and then when I changed it back to 1600, i was A-OK.
Just in case, I am going to run memtest tonight.
