PC wont switch on

hey guys just a quick query, my PC wont switch on this morning, worked fine all night, i tried to turn it on a few times, I put the PC sideways on my lap and made sure all cables are in properly, then it did turn on, i managed to get onto windows and run it all fine, so i decided to shut down and put it back, now it wont turn on regardless of where it is, I only bought the new psu in august (and unfortunately for some reason I didn't get it here!) and I'm worried its now blown itself, I have an old OCZ one bought from OCUK but that had a voltage issue on the 12v rail, I will try that and see if its the new psu but can anyone explain why it may of worked while sideways and not upright.

many thanks for all replies!

loose psu power cable or memory moving around can cause it to not boot,or a short between the mb and case

thanks, its strange it went through about 10 attempts then started to work again properly, like it was going through powercycles

what are your system specs? could be memory cold boot issue,try with just one ram stick installed
