Windows 7: pc was running fine then turned off

pc was running fine then turned off

hi all,
my pc was running fine. i was playing a game for a few hours. i then left the room for a few mins n when i returned to my pc it had shut down. i tried to turn it bk on and nothin. no fans leds nothin. i unplugged everything for a min then plugged bk in and retried to power up. i unplugged everythin again n went to bed. then this morning i plugged everythin bk in hit the power switch n guess wot. it booted up with the usual options after an unexpected shut down. safe mode, safe mode with netwrk n so on.
so i booted into safe mode n all was fine.
my thinking is that it could have been a short or something so ive gone all through my cables n cant find anything......any suggestions folks???
thanks in advance, any help is always apreciated

everything is new

Do you have the power cord plugged into a surge protector? Sounds like you got a power spike and got real lucky.

Has this happened before? I would definitely keep an eye on this, if it's reoccurring then it's some sort of hardware problem causing the shut down. If so, I would start looking at PSU, CPU and Mobo first. With these it's so hard to actually pinpoint the specific piece of hardware causing the problem.

Note: surge protectors do and can go bad. It's recommend to change them out every 2 or 3 years, if I remember correctly and don't skimp on them either. You have to look at them as an integral part of your system, which is almost always over looked.

hi again bassfisher
nah its the first time its happened. its run fine over the last few months. with all the changes made. i re-did my cable management on the day it happened. but have been through it all with a fine tooth comb. it hasnt happened since. the surge protector that it was plugged into wasnt a very good one so i bought a belkin one off ebuyer yesterday. which has now replaced the cheapo one. saying that i dont think it cost any less than the new 1. it just wasnt branded.
its proppa confused me lol. i had the pc built in jan this yr, had no probs with it but wasnt happy with it so i scrapped evrythin apart from ram and gpu n started again in a new case. i havent had any probs with any of the components untill this. i thought it may have been a loose connection where the power swicth connectors connect to the mobo but that was ok. i re-did it all anyway just to b safe lol. touch wood it hasnt happend again yet
thanks for ur advice, much apreciated as usual

Hm. I woulda guessed heat problem before going to a spike... how's your cooling?
Could it have been as simple as the new cable arrangement blocking an exhaust vent?
