Hi All, I usually sort out my PC Ok but this has got me a bit stumped so grovelling on the forum for a bit of help ..
My AMD Quad core/8GBram/SSD boot PC has been flying along with its GTX 295
Card for a long while , but now I decide to up to something that can support DX11 and above.
So just bought a R9 270X 4gb Sapphire card.
Took out the Nvidia drivers bunged it the R9 and it booted up got the Win 7 desktop and after a Few seconds with the big ( no driver) low Res display ....I get a black screen no display.
the PC is still working but no picture.
Also when this happens , strangely my External HD/USB/Card reader switches out too .. ( its on its own external PSU, so why should this happen ? ) can't see the relationship ?
A reboot and its the same .
With the USB Was wondering power ?? but then the PC has a 750w gaming PSU with 2 24Amp 12volt rails that runs the power munching 295 with no problems ?.
The Mother board is an AS rock A790gmh with 8gb Ram.. an SSD boot drive and a 2TB storage drive.
Just popped the 295 back in to type this in ..
maybe Card & Motherboard compatibility ??
PCIE 22 vs PCIE 3 ??
Was running an Old BIOS , and got all the above symptoms.
Upped the Bios to the latest ( still a couples years old Bios) and it wont boot at all .
But OK with the 295 in ? so still using the later one .
Any clues peeps ??
thanks
Chris
