I've had a computer for a couple of years now and my computer has now started crashing when playing just simple games like rimworld etc. As a Beginner in computers, I downloaded core temp and MSI afterburner, I found out that my cores are holding quite steady at 35*C idle but my GPU is currently sitting at 80 when idle! I've got 2 case fans (only got 2 spots for them kind of a bad chasi) I have a GTX 760 as my graphics card and a I7-4770 core I don't really know what else to do? should i get a new graphics card or just invest in a new computer? please post your suggestions anything is appreciated.
