Frequent Crashes after GPU installation

[TheRunningBear88]

Hello There!

 

I'm experiencing quite a few crashes since I installed my used (by a trusted friend) R9 280 (no x). always happens when running steam games but does not discriminate to a single one (Skyrim, L4D2, Borderlands 1&2, and Bioshock 1&2 have all crashed at some point.) Also Does not descriminate against steam Origin's Plants vs Zombies Garden warfare has crashed once as well

 

Complete system:

AMD A6-6400K Dual Core 3.9ghz (4.1ghz turbo) Stock cooled

Zotac Motherboard Mini ITX FM2 A75ITX-B-E

8gb Crucial Ballistix Sport RAM 1600 mhz

Corsair CX600W Non modular Power Supply

Adata 64GB SSD (Windows 8.1 64bit, a few other apps)

WD 1TB Blue HDD

GIgabyte R9 280 (slot is PCIe 2.0, its a cheap mobo) 

 

All drivers are up to date as of 4/30/2015

other than these crashes the system works fantastic

Crashes ingame and only ingame

Could be the shit mobo.

What crashes?  Game crash? System crash? Driver crash?

[TheRunningBear88]

@Samfisher Only ingame and can either just crash the game or may crash the entire system

Maybe PSU? bad connection somewhere? maybe board but doubt it

Drivers?

[AGuyInAChair]

Wild guess but maybe its a driver issue between you apu's graphics driver and your graphics card. Try disable the apu driver under my computer > manage > device manager > display adapters. Right click the apu and disable. 

 

Be sure to set a restore point because you can never be too safe.

Try reinstalling any prerequisities like directx, .net framework etc. It's unlikely because you would get an error message if that was the fault.

@WolfZombie The apu didn't even show up under display adapters....
