Problem with CPU temps, really weird, please help!

Jul 24, 2013 10:19AM PDT

Ok so the flow of what's happened goes...

- CPU started rapidly hitting 90+c so figure it was the coolit Eco pump that was acting up.
- Bought and installed a corsair H100i, turned the pc on, still getting crazy CPU spikes from cold boot.
- switched to low power mode, turned off turbo via bios.
- start up, CPU still climbing quickly to 60-70c.

Now this is all confusing because it seems like the CPU is just going crazy. But then it gets even weirder.

- When the temps are stable enough from bios (around 50c) I continue to desktop.
- upon loading the desktop it has the network loading symbol in the tray but it looks frozen. None of the system start up program's start and although I can click around on the start menu, I can enter control panel but if I click on any program's or desktop shortcuts nothing happens.
- on a few occasions it would eventually do a blue screen memory dump n crash.
- starting in safe mode is fine and everything works on the desktop.

Also the CPU fans are running at about 2000+rpm.
I really need help on this, I can not figure it out. It feels like the whole system is going.
I'm really annoyed though because I just dropped £95 on this new CPU cooler and the old one may have been fine after all!

My pc specs are:

I7 2600k oc'd to 4.2ghz
Coolit ECO C240 ALC CPU water cooling (old)
Corsair H100i CPU liquid cooler (new)
Arctic cool mx4 thermal compound
HAH 922 with large side panel intake fan

Asus p8p67 rev3.0
Corsair tx750
Gtx 670 ftw
8gb 1600mhz ram
3year silver warranty

Overclocking is known to cause overheating
Jul 24, 2013 10:27AM PDT

The first thing you should do is to turn off overclocking and see what happens. At best overclocking will shorten the life of your components, and at worst it will burn them out. When the temps get over around 80 degrees C, that can cause component damage. I hope it's not too late for you.

CPU is in minimalist state, though OC has never pushed it
Jul 24, 2013 9:52PM PDT

Yep I have disable the intel cpu turbo as well as intel speed step.
The cpu is on a extreme power save mode.
Have re-seated the cpu cooler a number of time.

What's strange is that if there was damage to the cpu/mobo/psu there would be other signs, at the very least there would be bios error codes on startup. And my CPU has never been stressed, the oc on it has always been moderate and it's temps barely ever went past 45c.
