A bit of context: I had Win7 and Ubuntu, tried upgrading to Win10 but couldn't, so a guy helped me and gave me Win8 instead. I recently upgraded to Win10 using my Win7 key, and now everything seems to work, except the following (which is why I'm here):
Here are my specs:
Notebook: HP ProBook 4730s
OS: Windows 10 Home, 64bit
CPU: Intel I5 - 2450M @ 2.50GHz
Motherboard: HP 167C (KBC Version 22.1F)
BIOS: HP 68SRR Ver. F.0A (07/18/2011)
and two graphics devices:
AMD Radeon HD 7400M Series
Intel HD Graphics 3000
The problem is that I cannot access the AMD one (e.g. dxdiag sees the Intel as the display adapter). At the moment they both appear in Device Manager.
What I've already tried:
-Uninstall the Intel display adapter in device manager -> doesn't jump to AMD, but to Basic Microsoft Display (after a restart and maybe a while, Intel takes over again)
-Uninstall the AMD (both with amdcleanuputility and DDU) -> AMD disappears from device manager, then install the crimson 16.7.3 -> only allows me to install AMD Install Manager -> nothing else happens (besides maybe AMD reappearing in the device manager, but Intel still in charge)
-Same step as above (after I use DDU again), with the latest crimson beta driver (the legacy one) -> same result
-Uninstall both AMD and Intel from device manager (or DDU, cleanup) -> left with Basic Microsoft Display -> tried the above steps -> same result (except after a while, Intel recovers again)
-Using Windows Update to install available drivers (both AMD and Intel) -> at 50% preparing to install the AMD driver, screen went black with a buzzing sound -> had to restart
-Same step as above, except this time it said there was a problem -> Retry -> now it says everything is up to date.
At the moment they both appear in the device manager, but I'm running on the Intel, as AMD doesn't do anything. I still have the AMD Install Manager (Radeon-Crimson-16.7.3-Win10-64Bit), but it can only install itself (?), and something called WU-CCC2, which doesn't seem to do anything either.
I'd appreciate any help I can get. Also, let me know if there's any other piece of info I should provide.
