A2 Code Can't Get Into BIOS

[hatefly]

Hello,
Recently my son had an accident and literally a single drop of condensation fell into my top vent and fried my PSU. Nothing else got wet at all and I promptly shut down my system. I replaced my PSU (exact same model) leaving all cables in place, checking everything for correct fitting. After replacement and a cleaning everything seems to be in working order however I now am getting an A2 Q Code. System will not let me go to BIOS and when pressing F1 to enter setup I get nothing.
Please help folks, you're my only hope!

All right

You have a problem with your gtx 660ti somewhere whether it be power to your gpu and psu or connectivity with your monitor.

It's possible you may have a faulty gpu too. Would you have another gpu to try besides the onboard graphics?

What psu do you have?

No I don't have another. A2 CODE happens if I have it connected our not unfortunately.

You say you have display with your onboard graphics correct?
