Hi,
I have a hp g62-b16st. It's a remarketed product with Intel core i3 2,4, 500GB HDD, 4gb RAM, integrated Intel HD graphics and dedicated ATI Mobility Radeon card (5470 hd I believe). This setting worked pretty well with 64-bit Windows 7 but recently I switched to windows 8.1 64-bit and now my hp isn't working. From what I gathered dedicated graphics drivers seem to be a problem. After installing updates, computer started to reboot itself continuosly. I restored windows to the state right after system installation and tried again- the same thing happened. Then I tried to install drivers from ATI- Catalyst Control Center didn't work. Every time I tried to install it (I downloaded multiple files, older and newer) I got the same failure of loading driver package. Then I found BETA drivers (amd-catalyst-14.6-rc2-windows-june23) and the restarting loop stoped but only due to the fact that ATI graphics weren't working properly and windows switched automaticaly to integrated Intel graphics.
That was all yesterday. Today, some update got downloaded and asked to restart my computer. when booting windows it said it is installing updates and I should wait for it to finish. Once it said 100% it started with the loop again. In safe mode I found out that windows figured out it is a good idea to install different driver that seems to be recognized as properly working one. And now the restarting loop is back. So I uninstalled that driver and disabled ATI graphic card for now but honestly I have no idea how to make win 8.1 work.
Oh, and I checked in BIOS- there is nothing I can do about it there.
Is there a way to make both graphic card and integrated graphics work on windows 8.1? If not, is there a way to turn ATI graphics entirely off?
cheers,
Martin
