every time i overclock cpu to 4ghz and run prime 95 my pc just shutsdown what does this mean not enough voltages? Why does my pc just shutdown but no BSOD and temps never go above 75 either. thanks in advance

system specs
i5 760
4gigs corsair dominator 1600mhz
750 watt thermaltake thoughpower
asus p7p55 lx mobo
gtx 580

this is is wut i set in bios

cpu vcore 1.37
imc 1.30
pll 1.80

Hmmm maybe up the PLL a bit, then try v-core (you could just have a not-so-great chip for OCing).
It shouldn't be the vtt (imc) you're only running 4gb ram (2x2 I'm assuming), if anythign that's a bit higher than you'd need.

You've got all power saving features etc disabled I'll presume?

EDIT:

Just took a look at your board; you've only got a 4-pin CPU header and no VRM cooling there whatsoever (not a lot of phases either).
I wouldn't beat on that too much (it's not really a great OCing board and you could fry it); also likely why you're requiring so much voltage on the chip.

i require a lot of voltages because when i set at 1.37 it runs at 1.35 on cpuz and if i run it on 1.35 itll be 1.30 or under thats weird

It's nearly impossible to "fry" a cpu since 2004 lol, the only way you could manage that is if you're using extreme cooling since the comp would auto shutdown (due to high temps) long before any damage could occur.

What does the CPU header have to do with anything?? The fan will run at 100% no matter what, this would only hinder his ability to control it. My 1156 rig uses a $38 biostar t55hd and overclocks 4.2 stable 24/7. Considering the 22x multi (24-25 turbo), most 1156 mobos are capable of pushing an i5 760 provided they have decent voltage control (if not you can still get 3.6-8 with small voltage boost).

Anyway.. Your problem may be cooling as overheating usually results in an abrupt shutdown rather than bsod. It normally wouldn't be an issue but the stock hsf for the 760 is abysmal, however 1.37 and 10 minutes of prime95 isn't too much so you should also check your vtt voltage and maybe bump the vcore as some chips require 1.4+ for 4 ghz stable.

^ I said fry the board, which is VERY possible when you don't have sufficient VRM cooling

so the whole pc shutting down is because of high temps i mean itll go up to 80 and thats the highest and boom shutdown. i thought even the stock cooler can handle up to 80c and not shutdown pc well not overclock that is.

i been trying to overclock this cpu for months and im pretty sure my cpu cooler is kinda average in performance not the best i think its kinda like the corsair h50
