Spec:
Asus p5q motherboard
Intel core 2 duo e7400 2.80ghz OC'd to 3.5
Msi amd radeon R9 270 OC
12gb ram
320gb Hitachi hard drive
Win power 700w power supply
I was stress testing my GPU with the msi afterburner app and the temp was getting pretty high (80) so I decide to shut it down but before I even touched it the PC just went off and now when I press the power button there is power for under a second and the fan starts to turn then just powers off, the green light on the MOBO is on and I have tried removing everything and starting it but it won't work, after looking on the internet for a bit I got the idea that i might have shorted the computer? Any help appreciated thanks

Update just tried it with nothing but enough to boot and still nothing but got small shock from the PC case when the power was on
