emm whenever i play gta v i get around uhh 1-2 fps and my cpu power spikes to 100, any other game or just using the desktop is fine. also rarely does the same with youtube. please help.

You get frequent GTAV crashes?

gta doesnt crash, it just gets soo bad until i cant take it so ill ctrl alt del and manually exit @Hastings

Try and add virual memory to all your hard drives. I had the same issues and its eventually going to become a memory leak. I use around 2000 mbs vurtual memory on each drive. 

Heres a tut.

Check the CPU/GPU cooling is sufficient; check temperatures whilst gaming.
