Screen Went Grey now PC wont start with Graphics Card

[KanQuex]

My sister was playiñg games on the computer when the screen suddenly went grey, and then the pc shut down after 5 minutes or so. Now the pc will not boot fully with the graphics card plugged in, tried both PCI Express slots. It is acting as though the PSU is insufficient yet the computer has been working fine for about 4 years, and the power supply was upgraded in the last 2 years. The pc does boot with the graphics card power supply disconnected using integrated graphics.

List of Hardware:
ASRock Z89 Extreme3
Intel i5 2500K Processor
EXtreme 2 625W Cooler Master PSU
AMD Saphire Radeon HD 6870 Graphics Card
A standard HDD and 8GB of ram

Current list of tried fixes:
- Reseated every component, and changed PCI slot for GPU
- Tried running system with just CPU and GPU installed

Any help would be very appreciated, could not find anything like this problem on google.

Sounds like the video card failed to me, it could be the PSU but I'd try a different card first.

Not a bad run for a 6870 ATI pci-e graphics card.

It did very well indeed to last four years.

When your card does this, and the extra power is connected from the PSU from the 12v Pci-e power connectors provided.
And the system then fails to boot, or power up on the next try KanQuex.

But it does if you disconnect the extra 12v Pci-e power from the card via the PSU.
It can mean that the card has seen the last of it`s days.

Either the Gpu has failed on the card.
Or the card needs a re flow to see if it fixes the problem.

If your confident, you can find guides on re flowing solder joints on old graphics cards, that can sometime fix them so they work again KanQuex.

That is all I can recommend to try and fix the broken 6870 card.

If not.

In any such case It means you can get a better Graphics card to play games with.
With better graphics and screen resolutions.
So that is a plus point considering you have an I5 cpu and 8Gb of system ram.

If anything the 6870 was letting the system down probably only had 1Gb of memory on the 6870 card also.
Upgrade time, can play more games much better with a new graphics card !

Yeah, sadly both of you are correct. The card finally croaked.

Try a re flow you have nothing to loose KanQuex.
You may be lucky and get the 6870 working again.
