I recently bought a mates old H60 to try and breath some life into my ageing X6 1090t which I had running at 3.6ghz on the stock cooler. Anyway, after using the bios to clock via the multiplier to 3.9...I rebooted and all seemed fine. Idle temps were 29 - 30 degrees. I then ran prim95 and within a few minutes my pc just died. Screen went blank and power indicator on case just flashing. Couldn't switch it back on, completely dead. However if I unplug the 8 pin CPU power cable from the mobo then I get power to all the system fans etc.... so the psu seems to be fine and giving out voltage. But with the 8pin cable plugged in I get nothing. Does this mean I've fried my CPU, mobo or both?.... is there anything else I can do to check?.... any help would be appreciated..my system specs:-

AMD phenom 2 x6 1090t
MSI fuzion 870a mobo
8gb gskill ripjaw 1600mhz ram
2x xfx hd7970 3gb in crossfire
Xfx 850w xxx semi modular 80+ bronze pus
Zalman z11 case.
 
Did you try resetting the motherboard? There should be a jumper on the board somewhere.

Ok I tried resetting my motherboard, using the coms reset button, the jumper and by removing the cmos battery. Still the same issue. No power. Does this mean I have to replace cpu/ mono?
 
Looks like textbook VRM failure to me.

Check for any signs of scorching, burning or fracturing of chips around the CPU socket.

MSI boards are known for this. Unfortunately removing the air cooler will have prevented airflow over the VRMs around the socket, this coupled with the high overclock setting could easily have caused a failure. Most other brand motherboards would be OK, however for any kind of overclocking with an AIO cooler I would always recommend a fan blowing on to the socket.

I would firstly check if the CPU is still alive. It's probable that it is. If you want a new AMD motherboard, then I would recommend one similar to that in my sig. It will work with the older phenom II and newer FX processors, so you can upgrade your CPU later if you wish.

Thanks for the reply....I removed the cooler from the cpu, couldn't see any visible signs of damage, or excess thermal paste...mmm Well it is what it is I suppose unfortunately. Regarding your suggestion of getting a new AM3+ mobo, I have a couple of questions. I'm sure my X6 was a bottleneck for my 2 7970's so would probably need to upgrade at some point. Would it be feasible to spend around the £200 mark for a new CPU/MB that would be a significant upgrade on my X6, that wouldn't bottleneck my gpu's and will be good for gaming for the next couple of years?...don't mind AMD or Intel. Also does anyone know if I can still use my OEM copy of Windows 7 that I bought when I built my pc if I replace the cpu and mb.
 
For SLI gaming I would see if you can get hold of a second hand 2600K. Get that with an Asus motherboard if you can and both could be hand for ~£150. After that I would be looking at 47xx CPU/Mobo but that would probably be out of your specified price range.
 
You can get an i5 and Z97 board for just a tad over 200, that would be your best move to make.
He's running Crossfire so he should really get an I7. I would generally avoid the 3770 as they ran too hot with out much improvement over the 26/2700 especially when it comes to gaming.
If you can stretch I would get a 47xx chip, but the best value and getting the job done would be 2600/2700k.

Thanks for all the input guys, however i think an I7 would be a bit much right now. My mobo dying has come at a bad time, with other stuff I've got to pay out on..like holiday, car repair..bills etc. No love for AMD guys?...you've put me off looking at AM3+ and an FX processor.....I'm gonna look around for a good deal on an I5.....would this board be any good to pair it with?

Looks good, cheap and has crossfire support. Looking at the specs it shows the 1 PCIe as x16 and one as x4....does this mean I would lose some perfomance in running crossfire?
 
Examine the price difference between a 8320 and a I5 with mono then decide if the price difference is worth it for the performance difference a lot of games depend more on the GPU than the CPU and with even a modest overclock a 8320 should fit your needs depending on what games you are actually playing. Of course a I7 would be best but that does not mean much when they are really out of your budget range at the moment, personally I would go for the cheapest option that fits your needs for the moment then put the mony saved towards a new build when finances are in a better situation
 
used 2600k/2700k + whatever decent motherboard you can find to overclock it on :)

Used sandybridge will save you a ton of money over new haswell / devils canyon, but finding the motherboard, weather used or new will be the problem.
 
Ok thanks for the advise all....after much thought, I've managed to buy a used (like new) Gigabyte 990FXA-UD3 SKT-AM3+ Motherboard, for 50 quid which was too good to refuse.....so for now, if my cpu is still ok, I can just drop it in and thinks about a proper upgrade a bit further down the line....thanks for your advise/suggestions.
