So, I was playing a game when suddenly my computer just shut off. However the power LED was flashing. Worrying my PSU had blown i quickly opened up my PC and checked it, It wasn't hot and i couldn't smell burning i unplugged the PSU and plugged it into an old PC to check, everything worked fine. So I turned to the next suspect, my heavily underpowered CPU, the cooling fan was VERY hot. So my assumption is the CPU overheated and got fried. My question however is, how can i be sure it's the CPU and not the whole motherboard? There is a green light on my GPU when i power the machine, but when i push the power switch nothing happens.

I just want to be sure what it is before i go out and buy a new CPU, to find out it was the motherboard. Hope you guys can help! Thanks. :)

System Specs:-
RAM - 8GB DDR3
Processor - AMD A4-3300 APU with Radeon HD Graphics, 2500 Mhz, 2 Core(s), 2 Logical Processor(s)
Graphics - NVIDIA GeForce GTX 650 TI
MotherBoard - MSI A55M-P33
PSU - 450w

Sorry. My bad. Did not address to that question. Pl remove your CPU from its socket. Install it again. Use only one RAM module, your gpu and cpu and try to power on the system and see if it works.

Read the temps in the BIOS and then using any software like HWMonitor and post your temps here. Meanwhile, remove the heatsink and fan off the CPU. Clean the residue off the CPU and heatsink. Clean the fan. Apply new thermal paste on the CPU and put on the heatsink and fan. Afterwards, check the temps again using both methods and post here.

Seems like CPU is throttling down but one needs to be sure. What about air flow inside your PC Case?

How can i do any of this if i can't get the machine to turn on? I have also cleaned the CPU and fan, there still seamed to be plenty thermal paste on the chip too.

2x4GB Ram. Bare in mind that non of this is "recently" installed. It's been running fine for about 4 months. Skyrim runs fine with max settings + enb mods as well as other games on max settings (Obviously some bottleneck from time to time) . However this shutdown happened while playing Batman Arkham Asylum. So to me it's looking more like Iv'e just pushed my poor CPU a little to far..
I also tested the PSU in another computer and that booted up fine, i also used an old (But working) 250w psu in my current computer (Minus the GPU) and still nothing happened. So I'm not sure its a PSU problem either. It's really confused me.

Always put new paste on when you've removed the cpu cooler.

Do a clear cmos by moving the right jumper (is in the manual for the motherboard) or removing the battery for about 5min. and take the pc from the power when doing that.Is powerplug out of the wall socket.
Try again with just one module of ram and switch those too when one doesn't work,also do this first working on the apu alone=monitor attached to the motherboard.

UPDATE:

So it seems it may not be my CPU after all. I tried removing and adding things step by step, and i found out that when ever i installed my Graphics Card the computer just refused to boot up. However i see no burns or anything to indicate the card has fried. The chip looks fine on it too. I'll have to contact amazon to see if they'll let me return it.

Is it possible that the card is fine and something else isn't working? Maybe the PCI-E slot?

If you have the possibility could you try the gpu in a different system.
It's also possibel that the psu cannot give the gpu enough power and just refuses to work with it attached.Checking the gpu in a different system might give what the culprit is.

I cannot check it in another system unfortunately. I do have an old system but it's mobo doesn't have a PCI-E socket. It would be strange for the PSU not to give it enough power as it has been running great for a few months now. I am however receiving a full replacement GPU in a couple of days, so we'll find out then i guess. I just hope it's not the mobo. :/

Hey guys thanks for all the help but I'm just going to buy a new Mobo + i3 processor it's due time i had an upgrade and I've just had some money come my way. (This should definitely fix the issue unless its a PSU problem) Thanks for all the help though! I'll close this thread now thanks :)
