Hi,

I have a Minisforum UM790 Pro which started behaving badly lately. The little machine is equipped with an AMD 7940HS CPU and integrated 780M GPU and I have used it as an office PC connected to two 4K screens since buying it in February 2024.

Early November I started having the first problems. I started having the famous blue screen with as stop code either HYPERVISOR_ERROR or CLOCK_WATCHDOG_TIMEOUT. However lately, it simply crashes after less than a minute after booting and it simply freezes without even showing a BSoD.

I have first tried every textbook solution such as running the memory test, running system scans such as SFC/ scannow or DISM /Online /Cleanup-Image /RestoreHealth. But all these did not show any problem on the device.

I then figured out that the problem was coming from the GPU. If I disable the AMD 780M GPU in the Windows device manager, the device runs fine again without any problem, but of course only on one screen and with a 1920 x 1080 resolution. 😞

As a result I removed all AMD drivers and I did a clean install from scratch with the latest available AMD drivers, but it did not help. From the moment I enable the AMD 780M GPU in the device manager, the device crashes within minutes. Next I went to the “support” site of Minisforum to search for the OEM drivers, but those are more than one year old and running the device with those drivers does not solve the issue either, it crashes within minutes as well…

Personally, I think that the GPU is toast, but I just wanted to check whether somebody has another thing which I can try with this annoying device before I declare it dead.

Thank you.

Given the lack of reactions, I guess I can safely declare this thing dead and start the warranty procedure...

i have the same issue (Freezing after setup AMD) since 2 months

What memory test was run? What is the speed and configuration of the memory? Is XMP or EXPO enabled? Have you tried disabling it? What are temperatures like? What cooler is in use?

I use both the standard Windows memory test and Memtest86+. Below you can find an image with the Memtest86+ running on the Minisforum device. Last time it has been running for more than a day and it did not find anything.

As this is a mini-PC it uses standard JEDEC settings for the memory and it has two Crucial 16Gb 5600 MHz DDR5 SODIMM sticks. I have been monitoring the temperatures before in the device with HWiNFO and those were all within the technical bounds. 

In my mind it is a hardware problem. As already mentioned in my first post, the only way to get this thing running is by disabling the GPU in the Windows Device manager (see third image below) or in the BIOS. The moment the GPU is enabled, I get a BSoD (as shown in the second image below) or the device simply freezes without showing a BSoD. The only thing I can add, is that Windows does not make any log-file with the error information that can be looked-up in the event manager. It just keeps on showing the BSoD screen at "0% complete".

I guess this what you get if you buy devices from second-tier OEM builders and unfortunately their customer support seems to be even below second-tier level based on what I have seen so far...

Assuming the latest BIOS v1.09 is already installed and the Minisforum support cannot offer any other suggestion then looks as though the only other avenue is RMA.

15 days ago, I was facing the same issue while working on creating an App for my business, I'm mentioning some essential steps to consider while fixing this issue.

Check for Overheating: Monitor your device’s temperature and clean dust buildup from fans and heatsinks to ensure proper airflow.

2. Update Drivers: Download and install the latest AMD GPU and CPU drivers from the official AMD website.

3. Check for Software Conflicts: Boot into Safe Mode to identify and resolve conflicting software or background processes.

4. Test Your Hardware: Run memory tests (MemTest86) and stress-test your GPU (FurMark) to check for hardware issues.

5. Check for System Stability: Reset BIOS settings to default and update the BIOS to fix any configuration or compatibility issues.

6. Check for System Errors and Corruption: Use sfc and DISM commands to repair corrupt system files or Windows image issues.

7. Reinstall or Rollback Drivers: Roll back to a previous stable driver version or reinstall the latest driver cleanly.

8. Perform a System Restore or Reset: Use System Restore to go back to a previous stable state or reset Windows as a last resort.

9. Contact AMD Support: Reach out to AMD support with detailed crash information for further assistance.
