Unit show blackscreen with backlight when run BurnIn 9.1 (1007) test

[Austin_Lien]

I run BurnIn V9.1 (1007) on my AMD Ryzen 5 4600U with Radeon platform, but sometime units have system black-screen and hang up.

Likely it is hardware failure or device driver bugs.

From the BurnInTest FAQ page

What follows is some hints on how to go about finding the cause of a particular system instability. (i.e. The system locks up, you get the windows blue screen, etc..). We don’t want to try and explain the steps involved in each of these processes, they are just points that may warrant future investigation.

• Check you don’t have any viruses.
• Check the hard drive for errors using the built in Windows error checker. (Right click on the drive letter in Windows explorer, select properties then tools / Error checking )
• Check that free space is available on the hard disk(s) for the windows swap file.
• Don’t run all the BurnInTest tests at once when looking for a fault. Run just the 2D graphics, then run just the 3D graphics, then just the disk, etc.. This will allow the problem to be isolated to one area.
• If BurnInTest is reporting strange errors, try turning the 3D test off. Bad DirectX 3D video drivers can cause a lot of strange problems.
• Know that faulty RAM can show up in many different ways. eg. Disk I/O error or a system crash.
• Boot Windows up in Safe Mode and see if the system is more stable.
• If you suspect faulty hardware to be the source of the problem, and you know what you’re doing, pull out all the "optional hardware", e.g. LAN cards, I/O cards and see if the system is more stable.
• Once again, if you know what you’re doing, start swapping out components of the system to see if the fault can be localized. Obviously you’ll need some spare hardware to do this.
• Have a look through the issues in the precautions section of the online help file.
• Check that the power supply that you have is large enough to power all the components installed in your system. A power supply typically supplies power at several different voltages (e.g. 3.3V, 5V, 12V). You should check that there is adequate wattage available at each of these voltages. PC power supplies are typically in the 250 - 500 Watt range. (Avoid power supplies that are 250 watts or less )
• Spikes in the main power supply can cause problems. If you suspect that you have dirty mains power consider getting a power conditioner / UPS / surge protector.
• Check that internal cards and cables are not loose and don't have dirty contacts.
• Ensure that your computer is operating at a reasonable temperature. Check that fans are operating correctly and heat sinks are making good contact.
• Make sure you have got the most up to date software drivers for your hardware. Drivers are a never-ending source of problems.
• Check that you haven’t ended up with an overclocked CPU and don’t know about it.
• Check that your BIOS settings are correct. Note down the original settings before you change anything however. You might also want to check that you have the latest BIOS that is available from your motherboard manufacturer.
• Check that you haven’t purchased the cheapest and nastiest hardware in the hope of saving a couple of dollars (or pounds, francs, etc.). Often it may not be the cheap hardware that causes problems but the quality and support of the software drivers that come with the hardware that are a problem. Don’t shop on price alone, check out the support and product reviews.
• If your system crashes, then check (1) the Blue Screen Of Death diagnostic screen for pointers to the cause of the crash (e.g. a particular device driver), (2) \Windows\Minidump\*.dmp for a detailed crash dump to analyze.
• If you’re really stuck you may want to try a reinstallation of Windows on a reformatted disk. Think carefully about this option before you attempt it, there are lots of good reasons why you don’t want to reformat your hard disk.

Hi~
We use BurnIn V9.1 (100 retest it.
Cannot see the system black-screen and hang up, but always show memory fail.
But we also use BurnIn V8.1 (1025) verify the memory, it's pass over 48 hours.

We don't found any memory error even if another memory test tool.

[David (PassMark)]

The memory test error in the log was, "No operations reported in timeout period". Which means the test stopped working (or more likely in this case that the test was extremely slow due to disk swapping).

It looks like this machine only has 3.4GB of RAM. Of which only 1.4GB is available. Then combined this lack of RAM with an insanely slow HDD.
So 1GB of free RAM this really isn't enough to run Windows plus modern applications. It would be a terrible machine to use for anything serious.

Then in BurnInTest you are running the CPU, Disk, 3D DX12, video tests. All these will use RAM as well. Especially 3D DX12. So there is probably no free RAM to actually test, which forces the disk to be used very heavily as swap space. And you are already loading the disk with the disk test.

This leads to thrashing & timeouts
