I tried to get my i7 920 to 4ghz yesterday, but after multiple tries it wouldn't boot.
When I press the power button, the fans spin for 1 second before they stop and it tries to reboot itself endlessly.
I've tried to reset the CMOS, take out the battery and ram and leave it like that for some hours but it doesn't help.
The temperature never exceeded 60c and the last stable overclock was 3.8ghz
The motherboard is asus p6t se and the psu is corsair 750w
Can anyone help?
Ok well that doesn't look too bad. QPI maybe a little on the high side but that's more of a personal thing.
So, the problem is even resetting the mobo it won't boot? No way to get into the BIOS?
Usually the reboot cycle can happen if there's a bad OC, and most mobos are programmed that if it reboots 2 or 3 times it will automatically return to safe default values and promt you to go to the BIOS.
When you said you've taken out the mobo battery, did you also unplug the PSU (or switch it off)?
Unplug everything, remove it from case. Set mobo on a cardboard box or similar non static surface, with only CPU and power. Turn on and see what happens (you might need to buy a mobo speaker to hear beep codes)
Then plug in 1 stick of RAM, and turn back on and see what happens. At this point it should be giving a beep for no video. Turn off again.
Plug in your GPU and connect the monitor, then turn on. At this point it should at least show the POST screen. Turn off again.
Plug in your boot drive and turn on. This test should get it into the BIOS where you will probably have to set it up again properly (namely, make sure the HDD is set to ACHI not IDE). See if you can boot into Windows.
If yes, continue plugging things in. If not, try swapping out the RAM stick.
Not really sure how to troubleshoot beyond this, as if it is just doing constant restarts it means something's fubar'ed and you'll need a voltmeter to test what's happening. As I said before, my guess is a faulty mobo.
