Hello guys, good day! As the title says, everytime I open games or even a google chrome browser, my monitor goes "No Signal" but everything is still running, even my GPU's fan. Everything was fine before I shut my computer off last night so I can't really say what might cause it.
After restarting, it works fine again, but as I open slightly heavy programs, there goes my screen again saying "no signal".

I've already tried:
hard resetting,
putting off and on the CMOS battery,
cleaning RAM and graphic card.
Still, the problem persist.

I ejected my dedicated GPU and used my integrated GPU, it works fine now but my FPS on DOTA 2 can't even hit 60fps.

Can I still fix my dedicated GPU? If yes, how? I know my computer is quite old but I don't really need to upgrade yet since I only play DOTA 2 and aside I don't have the money.

Here are my PC specs:
OS- Windows 7 Professional 64-bit SP1
CPU- AMD A10-5800K (Trinity) with AMD Radeon HD 7660D Integrated Graphic Card
GPU- MSI Radeon HD 7750 Dedicated Graphic Card
Mobo- MSI FM2-A55M-E33 (MS-7721) (P0)
RAM- 8.00GB Dual-Channel DDR3 @ 665MHz

It's possible but I would further trouble shoot before it's considered a complete loss. Firstly make sure the dust is cleaned thoroughly clean thru...


What is the wattage and rating of your PSU? It may not have enough power to run the dedicated GPU. Even it it had before it's possible its output has degraded over time due to age.

Also how old is the GPU? It very well could have a short and when it loads up shuts down causing the no signal on the monitor. With that you'd have to replace it.
 

Thanks for answering sir.
I have a 650watts M-Series CE ATX. I purchased it just a year ago. I can't seem to find it's PSU rating in google.
While my graphic card is about 4 years old now. It's most likely my GPU gave up already?

 


It's possible but I would further trouble shoot before it's considered a complete loss. Firstly make sure the dust is cleaned thoroughly clean thru the fans and heatsink. Could try monitoring​ the GPU temps tho off the top of my head I don't know of a software for AMD. Also make sure it's completely seated and mounted any sag could hinder a connection. Check for any cracks or oxidation on any of the power connectors going from and into the GPU.

I would also try to completely delete the AMD drivers and reinstall the latest. It could be a conflict cause by "stacking" drivers. Google search should easily guide you thru the steps. Good luck and let me know how you fair.
