Hello, firstly if this is wrong section please can someone help me move it.

I have built my own pc and has been running fine for nearly a year about 2 days ago its started tripping by this i mean it randomly restarts by itself no blue screen therefore no mini dump. at first i thought this was a software issue so i system restored, then i tried reformat then i tried memtest (which i did each individual stick and all fine), i had a error before which was serge protection activated so i got a brand new power supply from overclockers and quite recxently had my GPU tested which was fine also. i just don't know what it is. I don't think its heat because max core temp is 50 and gpu is the same under medium load (idle cpu = 40, GPU = 37, it is 33 degrees here). any advice would be deeply appreciated. also it restarts when it wants really sometimes when im just watching a film or when im running a game, maybe 5 min maybe an hour. I also error tested my hard drives which were fine. i have searched through so many forum threads which have this problem but there solutions have not worked. one final thing to add in my computer logs it says kernal power 41, i would also like to add yesterday the electricity of my house just restarted without a trip on the fuse board so im just wondering if this has fried my power supply again. the computer does work as im using it now its just when i play a game it will restart so maybe under load it has this issue.

well that's what i thought so i rung up overclockers and they said reset the overclock which i did by removing the motherboard battery but it still happened.
 
ok bro i'll make the partition now it shouldnt take that long but il post back and see what happens, thx for all the help so far much appreciated.
 
no that's with the overclocked profile loaded, yea i dont think they are very accurate because they change so quickly and sometimes are normal other times are in the red. i do have spare parts they wont work with this system because compatibility is different they are old. well thats the thing what is my next step because ive ruled everything out the last thing is the partition really?
 
ok fair enough its worth a try right, i''l reboot on the 500gb hard drive and unplug the ssd and play some games to test it out and report back to see what happens
 
ok here's a update, i went to do a partition and it restarted 5 times after getting to the windows screen every time so in the end i turned it off. when i came back and turned it on it said overclock failed reload profile. so i reloaded the profile and it was fine for about an hour until just now. im not 100% but seems to restart under load or about 65 degree on the processor so im not sure its anything to do with boot device i think the error is to do with power because before hand i set my cpu voltage to 1.320 but once i reloaded the profile it sets it to 1.365 so its either not getting enough power or something so it just cuts out. and jeckulz my issue is not the same as mine dosen't restart or shut down it basically just dies instantly.
 
im almost 99% sure its not the ssd as it only happens under load, the ssd is just for boot but il reset the overclock to stock then try partition on other drive and see if that actually works this time.
 
ok so ive formatted my drive again and installed windows 7 ultimate 64 on it this is the normal drive not ssd, there is no overclock as far as i am aware its clocked at 3.9 which i dont think is stock but is the automatic setting once bios is reset. so far so good im running some games on it, il keep the games running all afternoon and see what happens. also the temps only hit 48 on cpu and 55 on gpu. il post back here if it restarts or if all is well tommorow, but just a question how do i know what the problem was, was it the overclock or the ssd?
 
Ok so basically it restarted again this time it gave a message:

http://tinypic.com/view.php?pic=erws3d&s=6

This was the same message before then i got a new power supply, so my conclusion is the power supply is faulty again and the power surge in my house basically killed the new one. so i will contact overclockers and see if they can give me another new one tommorow. is there any way of stopping this happening in the future maybe by using a serge protector lead like a special one for computers? the only thing is i dont understand why this is happening because the electricity has tripped before but like tripped a fuse on the house then you reset it and all is fine but yesterday when it cut out it didnt trip a fuse is just went. but yea anyone know my next steps?
 
Yea thank you so much for all your help ive been on this problem all day now, im just worried overclockers wont replace the power supply unit because it was replaced a week ago, the thing is it wasent my faulkt and i wasent aware of the problem but i will ring them tommorow and see what they say. what do you mean post on the motherboards forum about contacting overclockers? and i take it i just go to the motherboards manufacture website for bios updates ? my board is asus
 
Yea thx for all your help today, i will contact ocuk and see what they can do for me im pretty sure the system is not getting enough volts as the bios said 3.3=2.9v 5=was ok and 12=11.8, so to rails are under voltage thats why it showed up in red earlier as well as just now. so hopefully ocuk can send me a new power supply and i can buy a surge protector, it does say the power supply has one but i guess it didnt work twice, luckly the motherboard does have one and protected all my components. i just need it to stop happening so if a surge protector on the outside of my computer can do that so be it, but i'll keep you posted
 
I rung overclockers today and they were like yea we will send you a brand new power supply no problem because they don't actually test power supplies. Only bad thing is i normally get them to collect the item however the guy on the phone was having none of it i was like i had my last one picked up because i have had issues with delivery before but he just wouldn't do it which sucks, so hopefully i can get my money back for the delivery relatively easily/quickly. Also i got that surge error warning again late last night so hopefully a new power supply will fix it because everything else is tested. This time im buying a surge protector before i use it because this is to much hassal to go through. im going to buy this one: http://www.officenerd.co.uk/info/Belkin-7-Socket-SurgeMaster-GOLD-Series-48077 which as far as i know has the highest voltage protection i can find plus its got a £unlimited warranty so if my system is damaged or data loss everything is fully covered. Any thoughts or anything to add>?
 
thank you for your reply i didn't check the power supply because i only replaced it last week so instead i checked everything else. ironically i have a multimeter and a volt pen sitting on my desk right now as i told my dad last night. but like i said earlier it is confirmed the problem is the power supply because i had a surge error warning twice now, unless you might know of a reason why i get random restarts, i have tested memory, graphics,hard drives, cpu and gpu temps are normal, rebooted so no driver issue it literally leaves the power supply to be questioned. but what i mean about the low volts is on my asus board it showed the 3.3 voltage as 2.8 something and it was red im pretty sure that never happened when the system was overclocked and was running fine. also to double check your information about the surge protector, so basically what you are saying is power supply's suck and provide hardly any protection and also that the surge protector im going to buy is pretty good ? (it has life time warranty on my system)
 
Yea basically they said if i checked all the components then they don't really know whats up so, but because its OCZ power supply they don't test it they just replace it instantly which is good so should be here tommorow or the day after, and im not touching it until my beastly surge protector comes which should also be here tommorow or the next day. if it still does it then i will check my bios and go through every single step westom recommended because i checked all the things a average person would do really he clearly thought of EVERYTHING which is good because it litterally leaves nothing unchecked and the better the advice the better my chances of solving this headache of a issue. problems with a clear indication of what it is are so simple but things like this are the worst. but hopefully it was just the power supply again that is what i am hoping for, but will keep you all informed because im pretty sure there's a lot of others with this problem who cant identify the problem because i went through a lot of forums with no definite solution.
 
Hello guys, a update got my surge protector and new power supply, to my worst fear it was not the power supply as it just restart again after a totally clean format. I really have no idea what this problem is and it seems nobody else does. please can you take me through all stages of what checks i should do to eliminate the problem please. Please can you also show as much detail as possible as I can build computers and no my general way around them but not to some detail i have seen on these forums. Thank you in advance.
 
another update ive contacted overclockers again and they said ive tried all that they would normally ask someone to do so im sending my motherboard, cpu and ram in for testing, keep you all posted.
