Earlier this evening my computer froze and I had to hard reboot it. It beeped continously and wouldn't come back on (the fans and harddrive seemed to kick in). Not sure what was happening and left it for 10 minutes before trying again an lo and behold it booted up fine....for about 10 minutes at which point it froze again! Restarted again and getting the same continuous beep only now it won't come on no matter how long I leave it
Somethings obviously died, but what? Is it the graphics card? I can go buy parts but don't want to spend money trial and erroring to find which part is bust.
If you still get the error after following these steps you can try to run the PC with one stick of RAM (if there are 2 or more of course), if the error occurs try another and see if the process of elimination can pinpoint a possible RAM problem.
I would also run memtest to check the RAM integrity. It is a bootable disk so you will need to set the CD / DVD drive as the first boot device in the BIOS and if prompted "Hit any key to boot from CD".
Halfway down the page is the download link for memtest86+:
had a similar situation, I just received a computer after doing a repair, and went to power it on and got the continuous beeping, looked up IBM's bios beep codes and It said it was a keyboard failure, so I plugged in a usb keyboard and mouse and boom the computer successfully posts now.
So if you have an IBM computer or an IBM based bios, make sure your keyboard and mouse are plugged in securely.
I had the same problem, it is your CPU burning, just put thermal paste or replace the CPU
