PC not booting after cleaning

[GomerPyle1228]

I decided to clean my PC because it was getting a little dusty. I only used compressed air to clean. After cleaning I went and plugged all my peripherals back in and tried to boot. When the PC tries to boot the power button lights up for 1-2 seconds and all fans spin up but then turn right back off. I have made sure that all the connections are solid and I did the paperclip test on my psu and the fan spun up. I am not sure what is wrong but at this point I am thinking that I might have killed my motherboard. Does anyone have any ideas on what could be wrong?

Probably blew a screw or something onto the MOBO causing it to short. Check for this.

Would this make the MOBO unusable? Should I go ahead and look into buying a new MOBO? Or will the MOBO possibly be usable if I remove whatever is causing it to short?

Probably usable after removing the short.

 

Also try reseating your ram, a cpu reseat, repaste would also be a good idea.

 

Remove the gpu and try to boot aswell.

I was not able to find a short. I have taken everything out of the case and reseated and repasted the cpu. The pc has started to power cycle now when I turn it on. When I turn it on, the cpu and psu fan will spin up and then turn off after about 2-3 seconds then after about 2-3 seconds will turn on and this repeats. I have also tried this with the gpu in and out of the system and with my ssd.

Try reseating the RAM and any expansion cards you have installed. Also if you have a G-Sync capable monitor unplug the USB cable from it (sometimes the motherboard mistakes it for an IDE device, no idea why). Also when starting have nothing but a Monitor, keyboard, and mouse plugged in.
