Green light but nothing starts

[Mishster]

Hi everyone, thank you advance for your help.

Yesterday I decided to clean the inside of my computer as it was getting beyond a joke how much dust was in there. I bought a can of compressed air from the local computer shop. elecom brand.
I turned the comp off removed the cords. I then took out the graphics card and sprayed it to remove the dust. Then I sprayed the inside of the case with the air. Once I finished I out everything back and tried to start it but nothing.
The only thing I have is a green light on the mb.
I have an old psu 400w that I thought I would try to see if it was that and I got slight movement from all the fans connected to the mb.
So I'm thinking I may have stuffed the psu?
I'm concerned because the air I used seemed very cold and I hadn't left the comp to cool down so cold hitting hit may have cause damage.
My specs are
CPU e6750
Mb. Asus p5k
Psu. Zumax 550w
Graphics: raedon 5750
Memory 4gig
Appreciate any feedback
Ham

Hi and welcome to Tom's forum.

Can you try with another PSU?

Thanks for the reply.
I got my hands on another psu and it worked.
Looks like blowing frosted compressed air into your hot psu is not a wise move. Expensive mistake.
If you Could answer one more question.
Why did the green light show up? Is that powered from the CMOS battery?
Thanks again

That means that you mobo has power but not the enough for boot up and run all components, those LEDs are used in mobos, GPUs and RAMs for give you the info that component still working.
