PC switches off suddenly ?

post #1 of 9
Thread Starter 
So since the past week or so my PC has been turning off all of a sudden without any warning in the middle of a task.It just goes off without going through the shutdown process.Am worried what could be the cause of this ? I suspect two things either my 4 year old worn out HDD which has slowed my PC down considerably and is the only part i salvaged from my older PC or the poor quality 350 watts coolermaster psu.
My PC specs in short are
Intel G630 cpu,8gb ram,hd 7750,H61 mobo,win 7 64bit.
I suspect the HDD because how old it is and how much it has slowed down my PC inspite of 8gb ram.It also makes random clicking noises and is surely dying off and i suspect the PSU because twice my PC has shut down while playing game so it could be PSu not able to supply enough watts ?Or could it be something else ?What do i do ? I have already backed up my important data

If it were your hard drive you would get a BSOD. Does the entire PC shut down, fans, lights, and everything? If so, it is likely the power supply.

Could be a mobo problem. Even PSU.

try out a few things pal

first

remove all the connections of ur pc i.e the 24 pin power the 4/8 pin power 6 pin gpu connector sata power ram GPU n reconnect them its sometimes due to dust,moisture n humidity in our India that this happens

second

remove your gpu n work on the pc for some hours if it works then the PSU is not functioning properly

lastly r ur temp considerable or high??

hope that helped thumb.gif

Perhaps the PSU fan broke and the PSU gets too hot and shuts down?
