Hello

Yesterday my PC shutdown ever 2-3 Hours without any reason.
So I decided to check it what's the problem ,so I just clean the RAM shot and remove the dirt from the case.
An I try to run my PC without closing the case,So when I turn on the power ,My motherboard is getting power signal(green light ) and when I start my PC ,my CPU fan start running but my SMPS fan is not running also I an not getting any display on my screen , also my hard disk light stop working .

If the CPU is overheating (or failed), the system may be shutting down in self-protection. Have you been overclocking? Have you reset the motherboard settings to default?

Replace the power supply. The fan in the power supply will be powered by a 12 volt supply which is also needed by the hard drives, motherboard and video card.

i agree with roger. You should probably check your cpu fan for overheating. Also, indiana is right; if the video card, etc are not getting the proper voltage; then certain fans may function poorly or in this case not at all.
