GPU or PSU Broken? Help!

[ZMI_FSX]

I built a pc for a friend around two months ago.

The specs: 

P5q Se PLUS

Xeon E5450

8 GB DDR2 

RX 470

Cooler Master MWE 550

 

So, he was able to use it for around two weeks before the pc started to go black screen randomly (even without GPU load). 

 

There was no artifacts, lines or anything that shows sign of a broken GPU.

 

Sometimes, if he waits for a few days, he will be able to play again for hours without any problem. Sometimes the pc won't even complete post. The diagnostic beep or lights will tell that somethings wrong with the GPU. 

 

What I had done:

1. Replaced RAM, still the same

2. Checked cables, good condition

3. Tried another motherboard, same no post at boot.

 

Could it be a faulty PSU?

 

Just found out that the Powerdevil RX470 in this pc was used for mining for over 2 years+.

You're in the wrong thread. Might be a heat issue.

Possibly.  I've had some bad luck with cooler master PSUs in the past myself.

Swapping for a known good PSU/GPU would tell you if one is bad.

I will buy another one just to test this. I'll inform you if anything comes up. Thanks!

The new PSU arrived today. No post. GPU Fault confirmed. Also, the RX470 that was bought was sold as used only, that's why I bought it. After a few weeks later, then I saw people complaining that it was a mining card. How do they know? Should I confront the seller and ask him for refund/replacement?

If the GPU is causing the NOPOST then yes you should get your money back.

yeah, usually you wont have problems with mining cards... but it was running for 2 years so you don't know how they were handeled. 

i would request a refund as ebay is pretty good about that.
