Improper shutdown ... Boot Failure?

[snadge]

SYSTEM: Gigabyte H77M-D3H - Core-i5 3470 - 8Gb Crucial Ballistix Ram (1333Mhz) - XFX Pro Core PSU - Samsung 840 SSD

Ive been leaving the computer on running for about 5 days without a reboot or sleep, I left the computer today at about 4pm and came back at 11pm, i pressed the keyboard and it would not turn on the monitor, the computer was on... so i had to reset it, when I did it restarted but then shutdown a few seconds later, I had to turn back on again and the BIOS screen appeared saying there was a 'Boot Failure' problem that stopped the computer from starting up, it gave me the option of going into the BIOS with default settings, i didnt, i just went in , restarted and the computer started up fine...

anyone know a way of finding out what could be the cause? ive looked in event viewer and nothing in there, im not familiar with dump files and I dont know if there will be any?

Iam running the 1333Mhz Memory at 1600Mhz - and its on Turbo too... wonder if thats the problem? (Auto Voltage)

EDIT: I restarted to go into BIOS and while tapping F8 the Boot failure message appeared again? i noticed it reported the memory speed as 1333Mhz even though it was set at 1600Mhz... the voltage was on Auto, should it work ok cos 1600Mhz ram runs at 1.5v too on these systems so OCing it to 1600Mhz shouldnt be a problem should it? - anyway I changed it back to 1333Mhz in BIOS and its started up fine twice...ive been running it at 1600Mhz for a while now, few months at least... not had any probs

any advice appreciated thanks

cheers

I would like to point out that its been running for months fine and since putting it back to 1333Mhz it has happened again, this time the computer was asleep when it happened, i had to reset it and it started up, shut off after a few seconds, then started up proper with "windows did not shutdown properly" (no bios message) when windows started my USB JoyPad driver was corrupted - ive been having some issues with this getting corrupted,but not as bad as the other day when I ran DSL Stats which caused a crash on my system (I think AVAST IS didnt like it, now removed Avast) - since that crash ive been having issues... I dont think its related to the RAM OC..myself, if it was it would have happened ages ago and the fact that ive been having these problems seems to point more towards the JoyPad causing issues?
