Is my GPU too old?

Question

Hi there. A short while ago when I played games my pc got bsod, and I found the problem to be my cpu was wearing out from age after comparing symptoms and one time I noticed too late the temperature reached 100c for at least an hour. So I upgraded my pc with a cheap i5 4590.

I tested again with Fallout 4, it played for 5 minutes before freezing at max 65'c, I closed the game and my pc froze for a bit before bluescreening. Critical process died.

Since my cpu is brand new, RAM is working. It's either my GPU or my Power supply can't handle the increased load of my GPU, even though it used to be able to do it fine at least 2 years ago. Heres what specs I have.

H81-P33 Motherboard, supports up to 4th gen.

i5-4590 3.3ghz Quad core

16gb(2x8gb) 1600mhz RAM

GTX 960 4GB OC Windforce(5 years old now)

Raidmax RX-530SS power supply, same age as GPU

Also sometimes when I boot theres colorful colors and I have to go into bios and the boot order is reset. I read its one of the symptoms of a failing GPU. The colors.

Will putting new thermal paste fix the problem or is it too late? It works for the most part but games crash when I try to use it, and I used to think it was my cpu. If it's too late will plugging a VGA into my motherboard fix the colorful screen and occasionally resetting boot order?

Answer 1

A cpu does not fail from age, and thermal paste does not fail if not touched.

If a branded PC you update drivers from the PC maker. If a self-build from the mobo maker, and only from the vid maker if an actual vid card

You do not update via win update or device manager
