@HP6203 Here's what you need to do, to identify the issue and resolve it accordingly:

• Check if an alternate monitor works fine on this computer, if not available, check the BIOS screen to identify if it's either a hardware or a software issue:
  • If it works fine on the alternate monitor or the BIOS (Accessed while tapping F10 during a restart for HP computers) it's a software issue & I suggest creating a new user account to check if that works better, for starters or contact the manufacturer or the desktop for support,
  • However, if it doesn't work within the BIOS or if you've got an option to check with another monitor and that doesn't work either, I'm afraid it's a hardware malfunction.

Thanks you very much for detailed reply.

I formatted the heirard drive.

Updated all drivers and bios from HP website

Then still gray circles showed up.

I disable Touchscreen driver, and have not seen gray circle since last two days.

If it shows p I will try second monitor as you suggested.

Again thank you very much for your help
