Hello

I built a brand new rig today with an HD 7750. It works fine with default Windows drivers, but once I get a proper driver the computer black screens after running for 1-5 minutes. Sometimes Windows returns with the message "Display driver stopped responding and has recovered", other times the screen stays black and I have to reboot.

So far:
- Tried drivers from Windows Update and Catalyst package from AMD (v 13.12, 13.12c and 14.1 beta). Wiped previous driver with Display Driver Uninstaller (Driver Sweeper).
- Installing just the driver without Catalyst software still causes crash.
- Sometimes Catalyst/Windows recognizes the cards as an R7 200 Series, don't know if it's relevant.

Specs:
Sapphire Radeon HD 7750 "Overclock Edition" 1 GB GDDR5
MSI H81M-E33 V2 Motherboard
2x 4 GB Crucial Ballistix RAM
SeaSonic S12II 430 W PSU

Really really really hoping someone can help...

In case someone else has similar issues, here's how I "solved" it:

Finally gave up trying different driver/software tweaks, and changed to my old NorthQ PSU. Computer then ran fine. Changed back to my new SeaSonic PSU and computer *still* runs fine. No idea what it was, but suspect a bad power connection.
