Think I've killed my cpu

post #1 of 34
Thread Starter 
First off, it's been a while since I've posted here so I'm not sure if this is in the right place, i not, I'm sorry, please direct me to the correct section of the forums.


Secondly, the actual problem. I had decided to try to get even more speed out of my E5200 cpu the other day, and managed to get it to what it said was 3.74Ghz, which I stupidly decided wasn't enough. I treied boosting it higher...and now I can't get anything on my screen. I've taken apart and re-built the PC, I've reset cmos with the battery and I've checked all my power cables are working okay, so the only thing I can think of now is that I've done something nasty to my CPU. I have a really bad feeling I might have overheated it, and only after the PC stopped working properly did I notice that my rear fans wires had snapped and that I'd lost a very important air extraction fan.


Does anyone know of a way I can find out if I've killed my PC without costing me anything? And if I have where I can get a new CPU and Mobo from for dirt cheap?

Intel CPUs dont just flat out die that easily. Having taken my E5300 to 4.5ghz on 1.6v and stress testing it at that speed and voltage (it got hot enough to trip the thermal throttle), and it still functions fine to this day. Its a little degraded, yes, but it still runs.

Now, before we continue, I am going to need your complete system specifications. Board, ram, GPU, PSU, EVERYTHING. This will allow us to figure out just what it is you may have broken, and get you back on your way to fixing it.

Board - Asrock 4CoreN73PV-HD720p R3.0
GPU - Nvidia GT640 OC'd to the max that afterburner will allow me (can't find out exactly obviously)
Generic cheap 600W psu
2gb unnammed ram and 1600Mhz
300GB sata HDD
Cheap blu-ray disk drive
unnammed standard disk drive

This is all I can think of that will be of use.

Generic cheap PSU... Yep that's probably your problem. The board likely didnt help either as ASrock's LGA 775 boards are cheap crap. Only foxconn boards are worse.

If you have spare hardware now would be a good time to bust it out to test your computer.

Well it powers up fine, and everything IS getting power and turning on. I've had a similar problem before and changing the connector to my HDD from the PSU worked...I do have an old PSU in a box...but the fan it dying (keeps making an awful whirring noise) And I'm not 100% sure it's powerful enough for my gpu, or has enough connctors for all my components. I'll give it a go and see what happens.

Tried my old psu, nothing. Just made an awful grinding noise (that fan is dead now) and still no picture :/

Pull the graphics card and plug the monitor into the motherboard's onboard graphics. Sometimes when these boards screw up they default back to onboard video.

Ah...I no longer have a vga cable or monitor...I'm using a hd TV with DVI connections...and none of the cables I would need to connect my PC to either an old monitor or my current TV. I'll have a word with a friend of mine with a beast of a machine and a room full of spare parts. All old, but he may be able to lend my cable and monitor until I get my PC fixed.

Here, try this.
Now adays, you don't actually remove the battery to clear the CMOS. Switch the jumper between the two positions and it should boot up.



That is for your motherboard also, taken from your manual.

So, parents let me borrow their monitor, and she still runs through the mobo, BUT, after letting the PC run system restore when she boots up she only gets as far as the two options, f2 or f11 for boot menu, then after a minute or two automatically shuts down. The first time when she seemed to run okay bios was telling me the cpu was running at about 57 degrees. Could the auto shut down before it can load up be due to overheating?

Also it still only goes through the VGA on the mobo.
