Missing Resolutions after Computer Restart

Parappa · 01 Apr 2017

Yesterday my Windows Defender picked some malware "BrowserModifier:Win32" and told me I needed a PC restart, so I clicked ok.

But when my desktop loaded up, my resolution had switched to 800x600. I went straight to the settings to turn it back (I believe it was at 1920x1080 before) but now the largest resolution I have is 1600x1200? So I am now stuck with everything on screen looking stretched.

Another thing that has changed are videos in general, there are slight flickers across the screen whenever there is movement while I watch YouTube videos or my own videos using Media Player Classic.

I tried a restart again but that didn't work. I then tried to update my Display adaptor: "NVIDIA GeForce GTX 590" and then tried uninstalling and reinstalling. Nothing changed.

I'm not a computer expert so if anyone requires any further information in order to help me out please let me know.

It sounds like a driver issue to me. Any chance your driver updated (via Windows Update) without your knowledge? NVIDIA has had this restart problem before and it may just be coincidence that you encountered malware and then restarted.

I would try either rolling back the current driver or updating to the latest driver (if not already installed).

Good luck,

Thanks for replying. It seems I'm up to date with the drivers and the "Roll Back Driver" is greyed out. I guess that means there was never a previous driver?

Also not sure why but I have 2 of the same Display Adaptors, is that right?

Actually, I'm not sure if you should have 2 entries for a dual GPU graphics card but that seems logical. Maybe someone else can answer that question. However, I noticed that both of them have an associated red triangle, and if that means the same thing as a standard yellow triangle, they are not functioning properly; therefore, if I am correct, you would not be receiving the full resolution benefit of the GTX 590 graphics card. Does each say "this device is functioning properly?"

If not, I would suggest you try to download and reinstall the latest graphics drivers or (alternatively) delete both entries and let them be rediscovered on next boot. You could also wait for more responses from individuals that actually have that card too!

Good luck,

Well I've tried a number of things now.

Uninstalled and reinstalled the drivers. Updated the drivers through the NVIDIA website. Even gave my entire PC a thorough clean, but I still get the same message.

Perhaps it's faulty hardware? Should I consider buying a new graphics card?

WOT · 02 Apr 2017

This problem could be the remnants of damage caused by the malware you removed. I would try a Win 10 clean install before buying anything new.

I've backed up all my files and reinstalled windows but those little yellow triangles are still there so I think I'm really out of options now.

Is it possible another piece of hardware could be causing this issue? I'd hate to purchase a new graphics card only to see the same Code 43 message pop up again once it's installed.

Because the GTX 590 has two GPUs in one PCB, it is only logical that Device Manager should detect those two GPUs, they're also linked together and basically they're two GPUs in SLI with one PCB.
