hi all , first timer here so go easy
have a new first build which seems to be having some bad symptoms ... new to all things regarding oc and such ... so i'm not going to play with any settings that i dont know about .... which is pretty much everything !!!
the system is :
i7 2600k
p8z68 deluxe
2 x 4gb corsair dominator gt
2 x gigabyte gtx 590 (running in quad sli)
ocz vertex 3 ssd 120 gb (boot drive)
600 gb velociraptor (storage)
swiftec external radiator water cooling
corsair ax1200 psu
first up .. installed windows 7 64bit and all drivers ai suite an so on and everything was going well . decided to give the thing a workout and ran ai suite auto tune to extreme and gained a 43% increase .. ran 3dmark and got some good results , was very impressed !! system ran fine all day all night .. till the next day when i got home from work . turned it on . fine . ran for 10 minutes then shut down .. ... power and reset buttons on the mobo were flashing ... but not in a good way .. unplugged and let it rest for a while .... turned it back on after about half an hour and upon boot got overclock failed msg ... .. doh !!! .. reset bios to default and ran for a while .. all good .... next day tried auto tune to fast .. thinking this wont be so bad ... worked well ran all night no probs !!! next day , start , boot , ran for half an hour then it shut down again this time no power or reset lights flashing at all ... nuffin ... unplugged power and let it sit for a while ... then a while more , took about an hour before power and reset lights came back on . next start up entered bios and reset to default again ... all well ... for about an hour . system shut down again ... internet search on trusty ol laptop ... found this site and started reading .... wealth of info ... good stuff .. just a wee bit over my head though ... had the sleep problem ... and the power up shut down power up before boot thingie ... next boot i disabled the pll overvoltage thing and went into os to change power settings to never sleep never hibernate hoping that will curb the sleep problem ... *fingers crossed* over the last couple of days the system boots up ok and runs , but it still shuts down at random times ... with increasing time before the mobo seems to "relight" the power/reset buttons ... and last night not at all ... more than a few hours hours ... i gave up and went to sleep ... tonight , home from work , power/reset buttons are on ... so just thought i'd pop by to see if this think tank has any ideas for me before i hit the power button ... it's an expensive build and the last thing i want is a pricey ornament ... any and all help will be welcome .... thanks guys
tiny update ... power and reset buttons on mobo have turned off without even turning the system on .... about about an hour or so after plugging it back in ... starting to get a not happy feeling ...
Looks as a PSU issue to me... But to be sure. When the power goes off, do you unplug the PSU from the outlet?
