How to know what is going on with the BIOS?  We have an HP laptop, it is an Elitebook 8540P.  We recently upgraded Win7Pro to Win10Pro. About a week later we had our first bluescreen. Has done that a couple times, then today went off and shows a problem with the BIOS, but it didn't say what.  We re-booted it and it has run normally since then. It's been about 3 hours now.  Also, this is running 2 external monitors, one through the DP port and one through a USB adapter device.

How do I figure out what is up with BIOS?

Is the USB adapter certified for Windows 10?

Good point. The USB device is made by "plugable".  I just downloaded a driver from https://plugable.com/drivers/displaylink and installed it.  Will see if that helps.

Also, I went to HP site to see about downloading drivers for this laptop, in case there are newer...but I could not find drivers for system 10, only system 7 and Vista.  Wonder about that...

I agree with above

  1. Prove that the laptop runs ok without the USB connected Screen.
  2. Check that the USB Display adapter is Win 10 Certified
  3. Make sure you have all the latest device drivers installed from HP as well as the USB adapter
  4. Try with one screen connected (the one with the connected via DP port

While there are some improvements in Windows 10, it could also be a resource problem.  How much RAM does the device have, is it sufficient with Win 10 and two displays.
