Beeping alarm and black screen on HP 22 all-in-one

[Tia604]

My desktop randomly had the screen turn black and alarm is going off constantly. It will not let me do anything on the screen, it is just black. I have tried turning off and on and unplugging and replugging and as soon as i turn it on the beeping begins.

@Tia604 -- those notifications could be a sign that your computer is overheating, and has been proactively been powered-off, to prevent the excess heat from permanently damaging your computer.

After your computer has been powered-off for a few hours, turn it on, and then feel the exhaust-vents, to see if you feel warm air being forced out of your computer, by the fan inside the computer.  If not air-flow, then it is possible that the internal fan has failed.

When i turn it on, no warm air is coming out. It feels cool to the touch and almost feels like a small amount of cool air is coming out? 

If it is the internal fan, is this something that can be replaced (can i do so?) or is the computer ruined? I have only had it a little over a year..

It is normal for a just-booted-up PC to push out not-too-warm air.

But, as the computer "calls home" (iTunes update, Adobe Reader Update, anti-virus update, Windows Update, et cetera) you should expect to find that the exhausted air is warmer.  But, you should expect to feel that the internal fan is working, and is forcing the air to be exhausted.

Yes, the fan can be replaced, if you can find a replacement part.

Access: http://PartSurfer.HP.com and enter your model-number, to see if the part-number of the fan can be purchased from HP, or if you see "N/A".

If you have to ask about disassembling any All-In-One computer, I advise you to NOT try to do it.

If you search on YouTube for "disassembly" along with your model-number, you probably will find a few "how-to" videos.  Look at the complexity of the disassembly, and decide if that is within your skill-set.

or is the computer ruined?

I hope not. Presumably, there is a reason for the issue. The only question is how much effort, and your money, that you want to invest in trouble-shooting & remediation.
