After taking my computer outside and cleaning it out with a compressed air can I took it back inside and turned it on. When I pressed the on switch it instantly made a fairly loud bang or pop sound and smelt like burning although I did not see any smoke. When cleaning I used only short bursts and kept the can upright at all times so I don't think at least any liquid came out. I unplugged it and the smell was coming from the psu which it was makes me suspect it. The dust build up was fairly a lot due to 3 years of no cleaning.

I am now really worried to start it as I don't know if this can cause further damage.

A power supply is not too expensive so I could replace it however I am worried about the other parts. How likely are they to be fried? Does the power supply have any protection against frying other components? If I buy another power supply might that be fried too? Is it safe to try and turn it on again with this power supply? How can I test the other components? What could have caused this?

System spec:
OCZ ModXStream Pro Series Power Supply PC 600W
Intel 3rd Generation Core i5-3570K CPU
Asus SABERTOOTH Z77 Motherboard
Asus GeForce GTX660 TI-DC2-2GD5 Nvidia Graphics Card
G.Skill 16GB (2x 8GB) Dual Channel Ares Series Memory Kit

Thanks

A Capacitor blew on the PSU. I doubt the compressed air had anything to do with it unless something got pushed around and shorted something out. Like a metal fibre or washer or something that fell inside the PSU. It could be a screw that was rattling loose inside the PSU.

I'll second the EVGA G2. Nice unit.
