Hi rifkianto welcome to the community.
Dell pc hangs at running mats test.
Make sure that the monitor screen is clean no dust particles on the surface of the screen.
When i select diagnostics from the f12 boot menu the system locks up almost immediately at the start of the psa.
Worse yet sometimes i had no choice but force reboot the computer.
Press and hold button 1 for 5 seconds.
Try running swapping the memory stick so try them one at a time and run the test.
Windows xp sp3 runs fine but i ve discovered some problems with the diagnostics that appear to be related to bios a11.
I m using a precision t3400 with a core 2 duo e6550.
All i know is that if you hold fn when booting a dell computer it runs a mats test.
To run the monitor built in self test bist.
Unplug the video cable s from the back of the dell monitor and the pc.
What is a mats test in computing.
Run built in diagnostics for your system.
What is a mats test what does it do.
To run diagnostics restart the system and at the dell logo tap the f12 key every two seconds.
If its stuck at mats test means its got something to do with the memory.
The dell monitor should now enter self test mode.
Running online diagnostics on a dell pc.
This will start the one time boot menu.
Run a full test to perform a thorough analysis of your dell pc or tablet.
Browse to the dell support website.
Also do all computer manufacturers have mats tests on their computers or is it just dell.
For that you may run hardware diagnostics.
Sometimes when the laptop froze i had to wait 20 seconds or so.
A gray screen should appear figure 4.
Also i can hear the fan running out loud when i watch videos on youtube.
This will run diagnostics on the hardware components of the system which may take around 5 minutes.
For information on how to run diagnostics and to determine the issue refer to dell knowledge base article.
Such disk failure could be a contributory factor especially if chkdsk runs while starting windows.
In case of repeated failures try replacing the hard drive.
If your dell computer is still locking up or running slowly and the troubleshooting steps above have not resolved the issue you may need to reinstall the operating system.
You want to get things done fast but your dell laptop just lags.
If the onboard diagnostics and other troubleshooting have not identified the root cause of the lock ups you may wish to consider running the quick test or full scan at dell pc diagnostics.
One last test you may run that is custom test on memory.
My inspiron is with windows 10 64 bits from a dell laptop user.
If you are unable or unwilling to reinstall the operating system refer to the optional steps section to see other potential solutions.
This test will take approximately 40 minutes or more to complete.
