Computer is shutting off during gameplay it used to handle

Oct 4, 2017 8:24PM PDT

Baseball card:

CPU: AMD FX-8320
RAM: G Skill F3-12800CL9-4GBXL (x2)
POWER SUPPLY: Antec HCG-620M (620W)
STORAGE: Seagate ST1000DM000-9TS15E
OS: Widows 10

My computer isn't that old, but recently it's been shutting off seemingly everything except the fans while running games. I've noticed that it only shuts off while running graphically intensive games, so I tried turning the gpu fan up to 100% in open hardware monitor, but it didn't help. I'm thinking it could be the power supply? Don't those fail after a certain time?

Shut off

Get a can of compressed air and a small brush.
Give the innards a good cleaning.
Pay attention to the heatsinks and fans.
Don't forget to give the psu a few shots of air from both directions.
Leave the side panel off and test.

Temp chart

Yeah, I got a can of compressed air and I've dusted it out, and the side has been off for a good while. Now I just use it with the side off. Here are temps for an idea of what goes on during a game:

If I'm reading the chart correct your cpu is going above 80c.
That is not good.
Verify the cpu hsf is attached correct.
Redo the thermal paste on the cpu and test.
That cpu is a 125w unit so it's going to be a constant fight to keep it cool.

Sounds like a plan

Gotta wait till stores open up so I can buy thermal paste. Now that I think back, I don't believe I applied thermal paste at all when installing my CUP. Could this be what's causing it?

Thermal paste

If you did not apply any then your cooler is not going to work very well.
Clean the old thermal paste if any and apply a fresh layer......test
