Recently, I've been having problems with my computer booting up on random occasions and it's becoming a nuisance. I will shut my computer off every night, and turn it back on the next morning. On certain days it won't even go through POST, and has a red LED marked 'CPU_LED' on the mobo. If I do happen to get it to boot, it will post normally, show the windows logo and the loading spinner for a few seconds. The spinner will then stop, and a BSOD will appear saying "MACHINE_CHECK_EXCEPTION". If I wait a few minutes and turn it back on, it will boot normally as though nothing was wrong.

Now, I know it might have something to do with the CPU. However, the only thing I can think of is it could perhaps be a power issue. Not really sure though since I'm not too much of an expert at diagnosing these issues. But it's just a feeling. Could it really just be a power issue, and upgrading my PSU would resolve it?

MACHINE_CHECK_EXCEPTION

A machine check exception occurs when Windows and your hardware platform cannot recover from a hardware error so that the system can continue to run successfully and reliably. More specific diagnosis of machine check exceptions is difficult, and there is no general solution. Contact your hardware manufacturer or a computer hardware technician for help with troubleshooting this issue.


Machine check exceptions are frequently caused by one of the following conditions:

a) You are running the processor or main board beyond its specifications. For example, you are over- clocking the processor or bus. We recommend that you run your hardware at the manufacturer-rated speeds.
b) Noisy power, overstressed power...

b) Noisy power, overstressed power strips, outmatched power supplies and failing power supplies can destabilize your computer. Make sure that you have a stable, reliable power supply to your computer.
c) Extreme thermal conditions caused by the failure of cooling devices such as fans may damage your computer. Make sure that your cooling devices are all working.
d) You have damaged memory or memory that is not the correct type for your computer. If you recently changed the memory configuration, revert to the previous configuration to determine what is wrong. Make sure that you are using the correct memory for your computer.

I would suggest you to update the driver for the display device on the computer.

You can refer to the manufacturer website to download and install the latest driver for the display device on the computer.
