My PC shows up an OC fail error everytime I start it up and i used to continue to Windows without actually looking for the error. Today, it has stopped working, it boots up and then on a blank screen stops and starts beeping with 5 sets of sounds. What is the problem with it?
HP Compaq dx2280 MT, Award Modular BIOS v6.00PG, Intel 945 AGPSet BIOS for 8I945GM-RH-HP V1.07
Per the service manual 5 beeps indicates a memory issue.
They describe two very similar failure scenarios, with some basic troubleshooting tips:
Blank screen and the power LED flashes Red five times, once every second, followed by a two second pause, and the computer beeps five times. (Beeps stop after fifth iteration but LEDs continue flashing.) Cause Solution Pre-video memory error.
1. Reseat DIMMs. Power on the system.
2. Replace DIMMs one at a time to isolate the faulty module.
3. Replace third-party memory with HP memory.
4. Replace the system board.

As per this manual http://support.hp.com/us-en/document/c02222922 5 short beeps - BIOS recovery successful. You should reset BIOS using jumpuper or pull off the 3V battery for a minute.
