So my pc was acting a little weird (running slowly, etc) so I decided to power it off and power it back on. When I tried to power it back on it started beeping. 3 long beeps then a pause then 4 short high pitch beeps. I've had this computer for 2 years and it was working fine yesterday. If anybody knows a fix to this thank you

Having the same issue with my Mother's HP All-in-one 24-B. She says, it started beeping after an update was applied with a reboot. 3 long beeps, 4 short beeps. After the 5th time, It shows the following message then powers off:
ERROR: Unsupported adapter installed
PC will automatically power down in a few seconds.
Anyone?
