switchable graphics dead? resurrectable?

Hoping you can shed some light on this. My Lenovo IdeaPad Y470p couldn't handle the upgrade to Windows 10. It got upgraded by mistake (spouse who shall remain nameless) and was overwhelmed--acted like it was under constant heavy load. I planned on doing a factory restore. This week, the GPU started acting funny...resolution went to 800x640 or something like that and I couldn't change it.

I did the factory restore to Windows 7 Premium 64bit. Upon boot, get the blue screen of death with an atikmpag.sys note. Check this out...

1. If I disable switchable graphics in the BIOS, computer boots fine.
2. If I keep switchable graphics active in BIOS, but enter Safe Mode and disable the Radeon HD 7690m, the computer boots but I get messages from the system telling me to install an AMD graphics driver and Windows also tells me it disables the Intel HD Graphics ("Windows has stopped this device because it has reported problems. (Code 43)").
3. It also boots if I do vice versa and disable the Intel HD Graphics and leave the Radeon HD 7690m active.

But option 1 is the only option that leaves me with a truly workable situation, because the system seems iffy in options 2 and 3.

I tried downloading drivers from the Lenovo site and installing them. Worked fine for Intel HD Graphics. Installing drivers for the AMD card crashed the computer upon install...and reboot gives me the blue screen of death!

I'm out of ideas...beginning to think this is a hardware issue. Hoping I'm wrong. What do you think?

 

Windows 10 has switchable graphics support built in. But not surprising, AMD has history of failing on Windows 10 since beta. MS seems to me don't care, it's AMD's fault far as they are concerned.

 

I should have clarified that I'm running Windows 7 now. When I did the factory restore I downgraded from 10 to 7. I'm having the blue screen of death when trying to load Windows 7. If I have switchable graphics enabled in the BIOS and I have the Intel and AMD graphics enabled through the OS, I get the BSD right after the Windows 7 splash. Disabling the devices through the OS Device Manager OR disabling switchable graphics in the BIOS allows me to boot.

Any thoughts?

 

JP$, AMD card might have died / is on the verge of dying. I suggest trying a clean Windows 7/8.1 install instead of factory restore as a last resort, but don't raise your hopes. Even if the AMD card is dead, the notebook is still usable without it. Given its' age, repair is out of the question; your options are use (or sell) as is, and motherboard replacement - the latter is feasible only if you can get it real cheap.

 

Thanks Starlight. That's what I was afraid of, but what I was thinking as well. Looks like I'll have to keep the AMD card off in the BIOS.
