What model board? The symptoms your are describing are signs of memory, processor, disk drive, driver, or poor system management issues.
What operating system? Windows 10? What version? 1909?
What processor model number?
What failure codes?
Thank you very much for your reply,
The board is MB-IN DH67BL,
Windows Embedded standard
Intel core i7-2600 CPU @3.40GHz , 64-bit operating system.
I purchased the whole system from Openeye USA as a cctv server 6 years ago. It worked very well initially but then last year I started to notice the freezing and lag. I contacted the company and they confirmed that the software is not the issue.
There are no failure codes.
Well, I would start by looking at motherboard, memory, processor, and disk drives, Unfortunately, there is no tool to test all working together.
Look in the system event log to see if there is some sort of pattern. I would even try replacing the power supply.
However, if you can confirm that all of these items are good, it would serve you well to install Windows 10. However, I am not sure you could upgrade to W10 - probably not.
Not that I am aware of.
You can try memtest: https://forums.intel.com/s/contentdocument/0690P0000056QOXQA2
and you can try IPDT: https://www.intel.com/content/www/us/en/support/articles/000005567/processors.html
If you have a spare power supply, I would try swapping them.
I would suggest updating your BIOS, but that is a touchy subject now.
Thank you again
What if I want to replace the motherboard and the CPU with something more powerful? What do you recommend that will work with windows embedded, seamlessly and with no fuss?
