Windows 8.1 | Weird acting PC

[Matthias0021]

Hello,
Sinds 01/07/2015 I've ordered a pc @ Alternate.

What are my specs?
- GPU: Nvidia GeForce 2GB
- CPU: Intel core i7 @ 3.7Ghz
- RAM: 8 GB DDR3 HyperX
- HDD: 750GB
- Power supply: Corsair CS550M
- Motherboard: MSI B85-G43 Gaming
[I can go more in detail if u need more info about it]

What is my problem?
For the last few weeks my pc started running weird, random freeze frames. Low FPS ingames.
Not working like it should.

Take a video from youtube and hold space while watching it, thats exactly how my pc starts to frame freeze.

Games where I had 300fps I now have 100fps (I know thats still enough but that proofs that something is not right).

I am a PC geek myself and checked all my hardware and it's running fine. I just can't seem to figure out what's wrong.

Drivers are up to date, checked windows updates, ...

NOTE:
Not sure if this has anything to do with it but when I use my pc's USB 3.0 port with USB 3.0 the transfer speed goes huge for a few seconds and then it goes very low to 5-10mb/s transfer. (Not sure if I had that problem earlier)

I hope you can help me!

Did you scan for viruses?

Yep, I have to say that I have way more adds then back when I got my PC. I'll scan it again. Any suggestions?

Reformat and use a proper AV like bitdefender, kapersky, norton internet security IN ADDITION to something like malwarebytes.

Of course, that's after reinstalling all your drivers first to see if it's not just a driver issue.

I use norton
Problem is already fixed ATM!
the problem: for some reason my google chrome had a high CPU usage at the time of the spikes. I reinstalled chrome and it was done! Maybe an extension for malware... I don't know but I'm happy I got rid of it.
