No video output

[exacier]

No video output from GPU and I can't test as I have not got a spare GPU/have onboard graphics. I have tried taking my pic apart snd putting it back together and it has had no effect. I don't understand because I had it running until I turned it off and tried the next day and nothing, the only thing I had done to it is cleaning the CPU heat sink. I have ordered a cheap GPU to test with before I return my card.
Specs: fx 6300, msi 970 gaming am3+, 8gb Ddr3 ram, 2x 7200rpm 1tb hdds, amd XFX r9 280,evga supernova nex 750w bronze. I should emphasise this a bit more, The only thing I have done since it was working is taken off the cup fan and cleaned it.

uhh, Did you maybe damage the CPU pins when you took off the old cooler? thermal paste can get pretty tough to remove.

All the fans are spinning? Have you tried doing a CMOS reset?

Yes. Re apply the thermal paste and make sure all the fans are connected. It sounds like something happened to the CPU. What you need to do is re apply the thermal paste after cleaning it good with isopropyl alcohol.

I mean all I did was take off one of the fans and spray its with an air duster. And I can't really see any battery/jumpers on the mobo. Everything is running as it would normally but it had high fan speeds on GPU when I tried booting twice but after that it was all normal but with no video output at all, not even a flicker.

The CMOS should not need to be messed with in this case. If you took off the CPU cooler make sure you re applied paste and cleaned it good. Also make sure everything is plugged in.

Everything is as it was when it was working before. Nothing has changed which confuses me.
I don't know of this is related but I started playing CSGO and my pc started to freeze/hang? And it would pause every 5seconds and it would seem like it was going to blue screen, do I imediately used task manager to close other programs and capped my fps which seems to have stopped it, could running CGO AT 300fps for 200h over 2 weeks cause GPU damage? Drawing too many frames makes my GPU create a high pitch sound/coil whine?
