About 2 months ago, I bought an ASUS RTX 4070 Super OC and a Samsung 24" 1080p 144hz display. The display was running fine until about a week and a half ago when, during a game, I was randomly dropped back to the desktop, sort of like game focus was lost. I could click on the game in the taskbar and resume. Then about a week ago, I would be randomly dropped to a black screen, no matter whether I was gaming, or looking at the weather. The only way to recover was to reboot.
Looking at the error logs really didn't show anything exact except I saw a couple of times that DWM.exe or the display driver would drop and recover. I did the following:
MY PSU is several years old. Could it randomly affect the GPU like this? I don't know what else I can try.
Looking at the error logs really didn't show anything exact except I saw a couple of times that DWM.exe or the display driver would drop and recover. I did the following:
- Replaced the HDMI cable. No effect.
- Replaced the 24" 144hz display with a 21" 60hz display. No effect. Hooked 24" back up.
- Ran CyberPunk 2077 (ran GPU at 174 F). Game ran fine for an hour.
- Ran Sniper Ghost Warrior Contracts 2 (ran at 130 F). Ran fine for an hour.
- Left PC overnight at normal Windows idle. Came back the next morning and display had crashed again.
- Removed HDMI cable and replaced with Display Port cable. Ran fine until the next morning when I had to reboot.
- Installed nVidia driver 2 back from current version. Black screen/reboot.
- Installed PCIe power cable from another PSU rail. Black screen/reboot.
- Did a repair/upgrade of Windows, install of latest nVidia driver. Start game and black screen/reboot.
- Dropped refresh rate of display/Windows to 60hz. Played games several hours, no issues. Left overnight. Next morning black/reboot.
- This morning had updates KB890830, 5028705, 5028851, 5026372, and 4023057. After those installed, ran OK for 4 hours then black/reboot.
- Removed 4070 and installed RTX 2070 Super OC (which I had never ever had a problem with). Started game and immediate black/reboot.
