I bought my rig over 5 years ago, and I had no trouble until now.
I am a PC user who keeps updated all drivers (including graphic driver) and windows often. While I was playing 'Medal of Honor 2010', my monitor froze and went black screen saying "Signal not Found, Switching to sleep Mode". After that, my CPU was still running, and my EVGA GTX 460 1GB's fan was still spinning.
Once I pressed reset-button, my screen went black screen again after BIOS booted and loaded Windows 10. I entered Safe Mode, and it works fine. Even I plugged my GT 8600, it works fine as well. I cleaned my GPU by using air-dust compressor and applying thermal paste. I plugged it back to my computer, and it works until 10 minutes later. My monitor went black screen again.

I have other computer at my workplace, so I plugged my GTX460 to it. GTX 460 temperature at Idle is around 50 degree celsius. Then, once I launched Overwatch, I just found out that once GTX 460 reaches 65 celsius, computer automatically shuts off.

I don't know why this is happening. I had no problem for using it even I played 'The Division' BETA with 720p lowest setting, smooth framerate and no lag.

Does anyone experience this before? Is there a way to fix this issue? Even I ordered GTX 970, I would love to use GTX 460 again.

My system specs:
Motherboard: GA-990XA-UD3
CPU: AMD Phenom II X6 1090T Black Edition w/ CoolerMaster Hyper T4
RAM: Kingston HyperX (4GB x 2)
GPU: EVGA GeForce GTX 460 1GB
SSD: Samsung 850 EVO 250GB
HDD: Hitachi 1.5TB (7200rpm) and Western Digital 1TB (7200rpm)
Antec High Current Gamer Series HCG-750 750W ATX12V v2.3 / EPS12V v2.91 SLI Certified CrossFire Certified 80 PLUS BRONZE
2 x 120mm fans

65C isn't really all that hot for a GPU. It's unfortunately possible that a solder joint has developed hairline crack in it somewhere and just happens that at that temp is when the crack separates enough for the card to fail. There are home remedies where you can stick your card in the oven to 'reflow' the solder, but the truth is that home ovens don't get nearly hot enough to melt solder (I've tried many times to no avail), and you'd have to take it a shop that does that sort of stuff. Might just be time for a new card sadly. Sometimes, these things just break and there's nothing you can do other than replace it. If, as you said, the card fails in a completely different computer the way it does, I'd say it's just reached the end of its...

What is PSU model name of your work computer?
Shutdown can be caused by:
1. CPU overheating;
2. PSU protection kicking in.

Actually, I would ask for both PSU models/wattage. I've seen a bad PSU cause wonky things, and it's the possible the PSU in the other computer simply isn't powerful enough to drive the card.

That power supply is more than ample. If your home computer has a similarly powerful power supply, then I would just assume the card is dead.
