Hey there, I'm sure you've heard this one before! However I've been searching for months without any working methods, for my friend atleast.

The crash itself is just a grey screen with some vertical lines(no specific color) sound does not stop and keeps running, so for example if a skype conversation is running- you can still talk and hear what other people are saying. Only option is a hard reboot.

So the problem occurs after 30-60 minutes of playing time on full load on all "newer" games, problem also occurs on Heaven Benchmark after about 20-25 minutes. The temperatures all seem stable and low.

My friends' specs:

GPU:Club 3D Radeon PokerSeries HD 7870 Joker Card XT(brand new! out of the box)
RAM: 8 GB(2x4)
PSU: Corsair CX600(which we also just switched, this computer originally had an astonishing 450w unbranded PSU!)
Motherboard: Unknown(as I don't have the computer with me right here), but it is an ASUS MB that comes with an Acer Predator g3610
CPU: Intel Core i5-2320
OS: Windows 7 Ultimate x64

This problem originally started after he wanted to upgrade his graphics card from a GTX 550 ti(which worked perfectly fine), he then got my old 7850 which I think was faulty from the box. Alright, so after that he decided to order a whole new card, that was working from the beginning but crashes became more frequent as time went on.

I've tried everything hardware related and I really can't tell what the problem is, if anyone got a solution I would really appreciate it!

PS: Not my picture, but it's the exact same issue my friend is having!

It maybe the old video drivers have not been removed.
I would check that the Nvidia driver is still not there on the system.
And also the Ati driver from your card you gave your friend to use.

Just a thought, if you find his card works in your system.
Also double check the specs on the new Psu he bought make sure it can provide enough amps on the twelve volt power rails to drive the new card. It could be the cause, but I doubt it but check anyway.

Should work with both ATI cards, will try to put the GTX 550 Ti back in later aswell. Reinstalled windows after implementing the new card aswell as installing the latest drivers. But with no luck. :(

It appears that the VRAM on your friends card is overheating which is causing the grey screen/vertical lines. Maybe try put an extra additional fan next to these modules on the PCB and see how that goes ;)
