Hi Team,

My PC is not working. When I turned it on for last time, there were some sounds that I could guess as the wires hitting the fan over the processor. (This might have happened as I took cpu to my friends house) I got panicked and hence could not dare to switch it on at the same time. Later when I tried the next day I find the that led's are not glowing, fan over the processor is not at all running and I dont find any sound in the cpu. I am very much worried as the system is not working. Is there any problem with power supply (SMPS) ? Is this a major issue? Please help me.

Thank You!

Does the Power Supply fan come on?

As the computer was moved I would first suggest opening it up and re-seat all the power connections as well as the RAM.

If you are unfamiliar with ESD read about it in this post first:

You can also get a PSU tester such as seen here:

Hi jephree,

I have checked with the connections. At first I am able to see that SMPS fan is not spinning. So could there be any problem with the power supply?

If that fan is not working then the PSU is dead or receiving no power.

Have you tried other power outlets?

Have you verified the cord is properly connected?

There could be a long shot of a bad cord.

Also plug straight into a wall socket for testing. No power strips etc.

Yes, I've tried with other main power supply sockets

Power cable is directly connected to SMPS from mains

Also tried with new power cord

I would suggest a PSU tester as I linked above.

However you could also try this crude method if you are feeling the PSU is shot anyway:
