I pulled it out after I started having issues, and I have used it before on this rig for much longer periods of time with no issues. PSU could be bad, but it looks/sounds/smells ok.
Are you installing just the barebones driver? Best practice is to clean all drivers off the system, then run the AMD installer, wait for it to extract, then cancel the installer. Then go to your Device Manager and right click the card, manually install the driver, that way you get none of the AMD junkware.
I use AMD Cleanup 1.2.1.0 with Windows 7, but you must
not use it with Windows 8 as it will corrupt the OS. This looks like it could work:

Go to Start Menu > Control Panel > System > Device Manager > and expand 'Display adapters'.
Right click the display adapter that corresponds to a Radeon 280X and click 'Update Driver Software...'
Click 'Browse my computer for driver software'.
Click 'Let me pick from a list of device drivers on my computer'.
Click 'Have Disk...'.
Paste the following path into the 'Copy manufacturer's files from:' box:
C:\AMD\Support\14-4-win7-win8-win8.1-64-dd-ccc-whql\Packages\Drivers\Display\WB6A_INF
Click 'OK'.
Select 'AMD Radeon HD 7800 [or 280] Series'.
Click 'Next'.
Your screen will flicker while the driver is installed. This may take a while.
Eventually you will see 'Windows has successfully updated your driver software'.
Click 'Close'.
Pretty sure something got corrupted somewhere in my software....I have an old SSD with a copy of Win8 and amd 13.1x modded drivers on it, and have been hashing Scrypt-N for the past hour to give the gpus and psu a workout, and it has not crashed or acted up yet. Disc is small and has no space left on it, so it is temporary but good for diag.
When I upgraded to 8.1 on my main drive, that actually seemed to rip out my 14.4 modded driver and I had to reinstall it basically as described above. You're forgetting a couple steps there, but yeah, it was running x11 fine until I started playing with the modded .bin file to gain some hash. I also had loaded the sgminer"fixed" version for a minute around that time when I hadn't yet matched TC in my config to what was in the .bin, so maybe that screwed something up....trying to reset to zero at this time and re-load win8 from my purchased valid copy of win8 and 8.1 upgrade is fighting me all the way. Invalid disc this, doesn't want to format that, etc. etc. I miss DOS. I should be able to figure this out with google and my laptop though. Maybe.
