Arctic silver and TIM-Clean from overclockers.
Clean it, if a thermal pad you may need to scrape it gently with the edge of a credit card (I'd advise against using metal).
Clean both the heat sink and CPU surface thoroughly, let it dry.
Apply paste evenly to CPU top surface, spread it thin with the credit card again, you are aiming for as thin and uniform layer as possible.
The CPU has thermal protection built-in, it is shutting down when an over temp condition is detected.
Fingers crossed no damage has occurred and that it is just a case of getting the cooler working right with the TIM (Thermal Interface Material).
I would advise against running the system until you have some new TIM too, PC World may carry it.
Cleaning and renewing is essential when removing cooler, dust and other detritus can interfere with the transmission of heat, plus the cooler rarely goes back on exactly as it was so some voids will be created, these in turn will lead to localised hot spots.
As you may know the TIM is to fill in hte microscopic variations in the surface joins between the CPU and cooler, air is an insulator, and improves thermal conductivity between the two components.
Often removal of the fan only will give sufficient access to blow the cooling fins clean.

Thanks your help i've ordered both, and will get them next week - it seems i've blundered in and wrecked my CPU's cooling.
I think i've cracked it, could not wait until Thursday for OCUK, so i nipped down the purple shirters and picked up some paste.
Got through 3dMARK (7231) - all at stock.
GPU never got above 70C and idles at60c-64C in my hot room.
CPU was back at 38C a couple of minutes after.
Thanks for your help and to everyone else who gave advice.

The 1.0004 patch was released 22nd August...improves multi-cpu support from what I have read..
And we're back to square 1, were we were before i RMA'D my 7950GT and before i re-applied paste, it still crahses my PC - i can't even get out the bunker now.
It's just not meant to be.
Still can't install the lastest drivers, however i attempt it, usng the DC step by step, it doesn't make aany difference the installling screen bar still gets halfway across and then stops.
It's not drivers anyway, this PC has been f***** since day 1, the moment it's asked to work hard - it fails.
5 Months and i still can't play games on it - even Rome Total War crashed earlier, that used to run for hours with a GPU that was faulty.
I bet 46 won't work properly either now. STALKER has never worked, and MTW 2 hasn't worked properly either. I'm almost a year on from when i first start to plan this rig, i wanted to get back to gaming, and after 11 months i still can't play a game to satisfaction.
First it's memory, then it's a bad GPU, now it's a CPU running at crazy temps and killing the PC - i also now can't install drivers even though i've been doing it since i was a kid.
It's just one thing after another, you solve one problem, and then another one pops along, it really doesnt make any difference.
Nothing the happened over the last couple of days has really prevented or caused the constant shutdowns, i've had constant shutdowns since the day i built it.
PC gaming has always been somewhat probelmatic, i go tight back to C64 and tape drives, thru the Amiga and right up to 2003. But nothing like this, nothing, it's just a constant fight i can't win. One hardware issue after the other.
It's a perfectly stable PC 24-7, it never hangs it never crashes, it's well maintained, but the minute i try and game on it it's F*****.
There's no way on gods green f****** earth i will EVER build my own PC again, NEVER. I should have stuck to my original plan of getting one built by Cyberpower, but no, i got seduced by saving a few quid.
Now i spend 4-5 hours a day trying to find solutions, trying to play games, over the last 2 days, i have spent 16 hours troubleshooting this piece of ****, on Saturday i had a (almost) top of the range GPU delivered - to what purpose?
I'm wasting my f****** time and money.
I rue the day i bought PC Gamer and saw the review of 46, i really do, i have spent thousands of hours planning this this rig, doing research, and it's cost me in total over £750.
I could have spent £100 on ssome 2nd hand junk to surf the net with.
Its a nightmare when it goes wrong ain't it!I had real hair pulling hours with this (my first home built)rig,but since I got it sorted,with the help of the guys here,its been totally stable.I think you need to go back to basics,take out everything you can,run memtest,disable drives,re install windows,the whole lot.
