R9 380 Keeps Crashing

[Miconderanable]

My PCS R9 380 keeps crashing. The crashes are random and can happen at idle. I ran a 5 Hour Furmark burn to get it to crash but it didn't.

 

The crashes can sometimes corrupt windows and i have to run a repair every now and then.

 

I tried reflashing the bios as shown here but it didn't work

 

 

Any ideas? I really don't want to buy a new gpu right now and i only have a GT730 to spare.

Is there anything that makes you sure its specifically your graphics card?
If it doesn't crash in furmark how would you know its your graphics card

I don't know if your video card is like the Powercolor R9 290 I have, but recently I took mine a part to redo the thermal paste. First thing I noticed was the thermal paste was on super thick because the blue thermal pads were way to thick.

 

Since I replaced the stock thermal paste and pads it's running a little cooler and no more black screen crashes. The card has always had some troubles but I noticed it crashed less when I had it in good airflow case and had GPU fans at full speed.

Repasted it like 5 times already, trying out new pastes to see if they make a difference.

 

Switched to pop OS and seeing if the card crashes there too. So far it hasn't.
