So i have the following rig -

3770k OC'd to 4.2GHz @ 1.24v (delidded) (was OC'd to 4.6 @ 1.28v)
Asus Z77 Maximus V Gene Intel Z77
16gb of 2400MHz gskillz tridantx
corsair 650w AX psu
6580 sapphire 1GB gpu
samsung 128Gb SSD (primary disc)
ocz 60GB SSD (scratch disc)
WD 2TB HDD

So recently when i switch on my PC nothing happens for a few seconds then i kicks into life, this has gradually turned to not turning on at all.
I had it OC'd to 4.6 @ 1.28v which is very mild i think, my CPU is delidded and a corsair h100 keeps it very cool.

So yesterday it would not turn on, i opened it up and the lights were on on the mobo for the XB S-Fi MB 2 integrated sound card so i know its getting power, i then stripped out the PC and removed the battery, i checked the CPU and cleaned it, reapplied the tim, checked the socket, it all looked 100%, no scorching or anything.

I then put the power leeds back on, the battery and one stick of ram only, i tried to turn it on and nothing so i swapped ram modules, nothing!

So by this point i thought my CPU must be fried....... Oh no it wasn't! I put my PC back together and thought i would try it one more time and it fired up, by this point i thought it must have been a corrupt OC?

So this time all i did was up the multi to 4.2 and left everything well alone, while testing the volts only hit 1.24 which is fine.

All day i was using my PC, switching it off and on again with no dramas, but this morning i woke up switched it on and it lagged again, from switching it on to it firing up a good 5 seconds passed?

What could be wrong with my PC? :confused::confused::confused:

many thanks Buzz
 
the thing is though when my pc isn't switching on the lights are on on the mobo? surely i couldn't be the PSU?

riddle me this, i pulled everything out, gpu, ram, battery, cables...... played blops2 for an hour...... put everything back in (like i did yesterday) and now it works?

it seems to work once the cmos and ram mem are clear... could it be the mobo or ram?

ty for all your comments and help with this, i really appreciate it :)
 
ok so ive updated my BIOS, i was on 1301 its now on 1802 O_o

**edit**

since updating the BIOS it is starting up faster, and the OS is less laggy, could the BIOS do that?

oh and i have started it up and shut it down countless times and its like new ?:/ ??????

ty setter, so i have an oc profile from my ram which i am not using, my pc is running fine with just a cpu oc, i think its a faulty ram module, but i cant remember where i bought it from?
 
i dont trust the asrock boards either ;)

well back from beach and it was slow to start :( i have removed all OC's now and im going to the pub...... if its slow to start again then i will look at changing some components
 
So I think you were all right about the psu, the lights are on but I don't think anyone is at home...... If u get me ;)

So iv bought a Thermaltake Dr. Power II PSU Tester and a XFX Pro Series 650W XXX Edition Modular '80 Plus Bronze' Power Supply.

I'm gonna test my psu, if its faulty send it back under warranty and use the XFX, I will then keep the Corair AX as a back up :)
 
If in doubt speak to the experts! Just called ocuk tech, I bought the board from them oct 2012, the chap diagnosed the issue as the mobo so I'm sending it back, I will test my psu as well just to be sure, it arrives tomorrow :)
 
So while I was packing my mobo away I found a blown capacitor next to the cpu socket, I just hope it hasn't burnt out my CPU as well? Where would I stand? Would Asus replace it?

Did you test the PSU in the end? I had a similar fault for ages and presumed it was down to spilling CPU paste on the CPU socket...it was the PSU that died around that time. Motherboard works happily!

If you haven't tested the PSU yet "FOR GOD'S SAKE. TEST THE PSU!!!" as otherwise this could also take out your replacement motherboard.
