Hey guys I'm having an odd problem - when I leave my computer and come back I find the screen blank. Clicking the keyboard "wakes" the computer and monitors but they continue to display black. At the same time my HDD Led blinks intermittently.

The odd thing is:

I have sleep, hibernate, and screensaver disabled. I have disabled all power controls in BIOS. My monitor is set to never turn off.

If the computer is performing some sort of task this doesn't happen.

Any help is appreciated.

This did not happen in Win7

This happens to me as well, but usually after 2 hours or more. I don't have a fix, I just stopped putting the computer to sleep. ACPI worked flawlessly for the first month. After some updates, which could have also been the latest AMD Radeon driver, I began experiencing this. I've recently stopped using DVI Out and have switched to Display Port to see if that results in any change in behavior.

Allright I got some more info

It is definitely related to my video card - which is a Radeon 7970

After some time the screen turns off and doesn't turn back on. Sometimes it turns back on, sometimes not. However the keyboard remains functional and I can switch songs, for example.

Unplugging the HDMI cable and plugging it back in fixes the problem.

However if I load a youtube video the entire screen goes green with artifacts and I have to reboot at that point.

      $80 or 90%, anything else would be financial suicide one way or another.

      Or... just use Bitwarden. Free, and has on-prem option as well. Works both on desktop and mobile, wherever you are. The age of local password files is over.

      I actually got to use one of those so called "backup codes" once. It was for a customer, I choose the backup code option, and by the grace of god, they actually hade them printed out. Imagine my surprise, when after using the backup code, Google then told use we had to enter a code they just sent to the gmail address we currently did not have access to. I was not amused, Google backup codes should be the end all get out of jail free card, because you had to have access to the account to even get them.

      On the topic of being locked out of a service. Recently two different friends of mine got locked out of their Google accounts. Both were hack attempts and one of them is waiting 30 days before he can get back in. He had backup codes and MFA but not a passkey. It was a browser token hack. Anyhow he has to wait 30 days for the dispute or whatever to end. The other person only had a password and is screwed losing all of the email, docs and years of photos. Google won’t help her at all. Her fault because she had no backup/recovery setup. Enable passkeys if possible. Also do NOT use browser based password managers. If using a cloud service make sure it is one you can fully sync to one of your devices so you can back it up. Like a PC or Mac with some backup drive plugged into it. Google is the worst to use IMHO. You can’t sync your photos at all. You have to use the “Take Out” service which is manual and takes days. That service strips the meta data from your photos. Also Google Docs synced to a device are useless without a Google accounts. MS Office/Libre Office is not going to open a link to a Google doc to a dead account.
