The other day my computer randomly restarted but only once so I went ahead and dismissed it as an issue. However, two days later my computer is now randomly restarting every 2 to 30 minutes.

I then updated all my drivers, scanned for any viruses and found nothing. I then booted my computer in Safe mode and suprisingly it didnt restart.

Then I went to reinstall Windows and while doing so my computer restarted twice.

These restarts aren't blue screens containing any error message but just instead the screen goes black and the computer restarts.

I then opened my computer , completely unplugged the power and gently cleaned it of any dust incase that had any chance of being the problem.Then when I started it up only the Power Supply fan ran and nothing else.

I have a Corsair CX750 power supply which is just past a year old, I have read reviews of them constantly failing and even reviews mentioning them causing constant random reboots and then just dying all together.

So currently my suspision is that my Power Supply is faulty and that I need to purchase a new one, however I have no spare ones which I could use to test and I know that random rebooting could be the motherboard, or even RAM issues.

I want to know what your thoughts are on the issue , your help and thoughts are greatly appreciated.

Hello UniClad,

 

I then booted my computer in Safe mode and suprisingly it didnt restart. 

 

 

The following suggests a hardware issue and possibly overheating.

 

These restarts aren't blue screens containing any error message but just instead the screen goes black and the computer restarts.

 

 

Please provide information about your computer, this includes is it a custom build or brand name such as Dell or HP, if it is a brand name provide the model name or series number (not serial) if a custom build post the brand and model name or number for the MB, Ram (including the amount) and add on video card if one is used, providing these details will enable us to better assist you.
