My Computer got some major problem

In order to help you, you need to post a lot more data. You need to post your exact system specs; ie exact motherboard, exact ram, exact pw supply, etc, etc. If this is a big box system ie dell, hp, whatever, post the exact brand, model# and service tag#
Next having 100gig free on a 500gig drive is not going to slow down your system. If you had 10gig free, that might slow it down however not having 100gig free. Common reasons for a slow system;
1 Overheating. The processor will throttle itself down in order to maintain temp
2 Virus/Malware
3 Failing pw supply
Check your temps and voltages; specifically cpu temp, system temp, 12V, 5V, and 3.3V values. Post those here. Most motherboard mfg have monitoring software for their boards however we have no idea what motherboard you have so telling you what software to use is impossible. There are third party programs like HWMonitor however they are not all that accurate.

 

These are the average performance scores for the processor and graphic card in your computer.



Since you use your computer for gaming, you should add another 4 GB of RAM and run it with 8 GB.
