All games, Major fps drop

[MrMiner5986]

I have a gaming computer which runs games such as mine craft and battlefield very well, but a few days ago the fps on every game that i have played has dropped to about 30 when it should be much higher, ive scanned my computer with Avast anti virus software, Comodo, de fragged all my files. All of the bugs/viruses that have appeared have been delt with but it hasn't increased the fps at all. Anyone know of any ways that can restore the fps back to what it was/Does anyone know why the fps drop has happened? (This is a constant fps drop, it doesn't drop after like 30 minuets of plying a game) I have a desktop pc.

My GPU is:
Intel(R) HD Graphics 4600
Total memory 1696 MB

Computer specs:
My processor is: Intel(R) Core(tm) i5-4670 CPU @ 3.40GHz 3.40GHz
Ram: 8GB (7.89 GB Usable)
64 bit operating system

You did not add a video card to your "gaming computer??"
If your monitor is 1368x768 or 1400x900, a R7 250X or GTX750 will be sufficient to get good settings in games. If 1600x900, a GTX750Ti or R7 265 will do. If 1920x1080, I'd get a R9 270, R9 270X, or GTX660.
