Windows cannot verify signature?

[redstarsarc]

Recently, I've been having this problem with my graphics and when I pull up the properties for the display adapter, I get this message in the status box:

"Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"

This problem started after installing windows updates. My computer hadn't been updated in a long time so there were a lot to install. Problem is, I'm not tech savvy at all and I don't know how to figure out what might have gone wrong. I don't really want to uninstall the updates because my computer's working a lot better now (it used to move at glacial speeds). I've tried uninstalling and reinstalling the driver. I've tried, now and in the past when it was working fine, to update the driver, but Windows just says it's already up to date. I tried following this tutorial: http:// to disable signature enforcement but hit a dead end in that 1) there is no disable secure boot option in the BIOS and 2) when attempting to use the bcedit command in the command prompt, I just get a message saying "'bcedit' is not recognized as an internal or external command, operable program, or batch file."

My PC is a Gateway, model NV52L, running Windows 7 Home Premium.
Processor: AMD A6-4400M APU
Graphics: AMD Radeon HD 7520G

Please help.

If it's not causing operational problems, I wouldn't worry about it. Are you downloading the drivers from the Gateway Support site for your system or from AMD (should be Gateway).

I'm not trying to download anything new, it's the same driver I've been using and that's worked just fine before. It's only after installing Windows updates that this problem began. According to my computer, the driver software is up to date.

The thing is, I play a lot of video games on my PC so a working graphics card + drivers is a must.

Does it work?
Are you running into issue while gaming or does it just report that it cannot verify the digital signature?

As far as I can tell, the graphics card is NOT working at all. In device manager, it's got a little yellow triangle with an exclamation mark and the "cannot verify signature" message shows up in the device status box.

When I try to play any of my games, they crash at launch with an error message. I don't have the exact message though as I'm currently away from my computer.

That looks to have done it. Thank you so much for your help!
