New Asus R7 260X GFX card not recognised in Device Manager. Please help

[Ray Walton]

Looked everywhere for an answer for my problem but cannot find one.

I have a WIn 8.1 set up on a Asus P5B-E Mobo (old now but still fast enough with the classic Intel E8400 Core Duo CPU and 8GB GSkil RAM), Recently my trusty and powerful old HSI HD4890 Ultra GFX card developed a very noisy rattling fan problem and no matter how much dismantling and cleaning it and the use of WD40 I cannot cure it. So I decided a new GFX card was well over due, and sure I was aware even a modest modern GFX cards today will be much faster than this old flag ship relic card I had. So got a Radeon Asus R7 260X card with 2GB GDDR5 memory, balancing price with needs ( most intensive use is for sim racing with rFactor 2 and iRacing as not a shoot'em up fan at all)

So removed the old HD 4890 graphics card and stuck the new R7 260X one in as I have done many times in the past. Plugged in one of the single 6 pin power plugs from the PSU and connected the DVI port to my monitor same as with my old card. Strange as the HD4890 used two power plugs a 6 pin and an 8 pin so this card seems light on power needs.

Problem is although I do get a screen up and can change it to 1960 x 1080 in Windows and looks statically good, it is slow and I cannot see it in Device manager and thus be able to install drivers, (thus why it is very slow of course). Tried everything, from looking in my P5B-E Mobo BIOS Version 1807 (nothing in there I can see to affect it) and reseating the GFX card. Even tried installing the drivers on the CD and they appear to install but CCC just shows no detected card as confirmed by nothing showing in device manager not even a Display Adapter heading in there !!.

So I am totally stumped. What next? Oh I tried completely uninstalling the old graphics drivers (should have done this first I know!) and removing the new ones too including CCC and then reinstalling them, but even after countless reboots there is still no sign of the new card in Device manager. It si just not recognised ??????? Never had this problem before ??

Any answers gratefully appreciated as just want to get my system up and running again with good fast graphics that I expect with the R7 260X What I thought would be a 20 minute job has now wasted nearly 4 hours of my time, grrrr !!! Ah well no good getting cross with it as that never helps of course

Uninstall all drivers from your old card and the CCC. download and install the newest drivers from AMD website.

Your motherboard doesn't seem to support Windows 8. Maybe that's you source problem?

Thanks for the replies guys and glad to say I have it sorted. Sure there is no problem with Windows 8 with my Asus P5B-E Mobo, as have been running it fine since January this year and a very stable OS that I love too.

But RobCrezz hit the nail on the head. Seems the drivers on the included CD do not seem to work well in Windows 8. So I downloaded the latest form the AMD site. Still though had lots of problems and was unable to install the newer drivers and CCC etc and realise in the end itr was caused by my not first completely uninstalling the old HD 4890 drivers and related software. What threw me was not seeing the Radeon card in Device Manager even with an exclamation mark, seems it only appears when you clear out all the old drivers and then install the correct new ones.

I had major troubles as there was now corruptions in my system. I had to go back to a Acronis True Image back up I had from the end of last week and reinstalled the old graphics card so was back to a working system again. Then I uninstalled all the drivers and AMD software. Then booted into Safe Mode and installed a registered full version of Driver Fusion I had downloaded. This utility application is excellent and uninstalls and cleans up ALL the display driver related stuff for AMD, NVidia and Microsoft, and saves a great deal of time and pain manually editing your registry etc. Driver Fusion is best to run in Safe Mode once you have uninstalled your main software and current Display card drivers normally before rebooting to Safe Mode..

Once I had cleaned it all up I shut down and powered off the PC, installed the new card and powered back up. Then it installed the new correct drivers and utility programs with no errors and sure the card now showing correctly in Device Manager.

Phew I wish these card manufacturers would try to make it more straightforward and give better instructions as to uninstalling old drivers completely. Really they should supply automated software on the included CD to do all this for you with good error trapping solutions too. So what I expected to be a 30 minute job has in fact taken me almost 2 full days of work to get my system back up and running as it was grrrr. But of course it is now better with the newer faster quieter graphics card installed and working.

Anyhow many thanks to this forum for your feedback and hope this may be of some help to others as well.
