It seems when I connect the monitor to my graphic card it only shows black in the display but the fans & keyboard lights run perfectly fine.

When I connect the monitor on the motherboard the display is fine. but someone told me that if you connect your monitor to graphic card it will increase the performance.
any fix to this?

For slow loading times, first thing I'd do is a clean Windows setup on a new hard-drive.

With the nVidia card you want to disable the motherboard video, go into the BIOS and set the default video to the add-on card.

You may also have issues with overheating, video card may be going bad, power supply may be going bad, but I'd start with a clean Windows setup unless you want to try a different video card or power supply first.

I hope I gave you what you want to know.

I bought my computer 3-4 years ago and it is perfectly fine until last week.
I have noticed when I am playing games, my FPS dropped from 60 to 10.
I check everything I can:

-I can't open my NVIDIA control panel it says like:
NVIDIA Display settings are not available (You are currently using a diplay attached to an NVIDIA GPU).
-someone said I should connect my monitor to my graphic card and the problem with NVIDIA was gone, my FPS jumps to 60-100. (but when I restart the PC. it takes 10-15 minutes to go to desktop.[Its fine for me])

-after I play games like 10 hours(not continously). It starts appearing white screen. but I can still play.

-One time, I try to open my computer. I waited 20 minutes and it is not open up(-The keyboard lights works fine[Num Lock, etc.]).

P.S. In Display adapters, both ATI Radeon HD 4200 and
NVIDIA GeForce GTS 250 is running properly
