2 days ago i booted my pc but it had some difficulty staying open. It was like it was restarting constantly. I couldnt even reach the bios menu. I thought it might be the Power supply. I turned it off from the power supplys switch ,turned it on again and booted. For some reason that worked and the pc booted fine. I even played for hours. At some point the pc crashed , i couldnt open task manager it was completely frozen so i restarted the pc but then the first problem happened again. Sometimes it works fine, sometimes i cant get it to boot .It crashed 3 times so far sometimes followed with the rebooting issue. My pc is 1,5 year old its relatively new . I think its the psu or some problem with the Ram.

My specs are :
Cpu: intel core i5 4460
Motherboard:ASUSTeK B85M-Gamer
Memory: Corsair Vengeance DDR3 dual channel 8 Gb
Graphics Card: Nvidia Geforce GTX 750 Ti
 
Solution
Whats your PSU unit brand?Download HwInfo and check your voltages , they should be in range of 5%-10% max, 3.3V, 5V, 12V, ram is less likely to go bad.
Does the air blow how from PSU?
