no signal and beeps

Recommended Posts

I recently had to Install a new HDD. The old one was failing, and I also needed more space and computer restarted on its own and kept getting worse. After I did, the computer began restarting on occasion for no  apparent reason. The event log never seems to have any reasons as to why. After looking for some time I found the patches for the meltdown and specter  issues and downloaded them and also was prompted to flash the bios. The computer continued to occasionally restart on its own so I turned auto-restart off (a setting in system settings) and did a registry edit that tells the computer to not restart with a user logged on and it seemed to work. Then it started loosing signal and beeping 4 times over and over . If i turn it off and back on it starts up and runs fine til it decides to do it again.I have tried resetting the ram and while i was at it cleaned the case and fans .Temp is staying cool around 38 degrees .Computer is also now showing a TPM issue and wants me to clear tpm but when i do it asks for password i dont have.

There are several reasons that a Hewlett Packard computer could beep four times, according to https://support.hp.com/us-en/document/bph07107 :


  1. Thermal issue (CPU or other component is overheating)
  2. CPU configuration error/imcompatible CPU installed
  3. Fatal error with motherboard or component such as the CPU
  4. Memory errors.

Given the problems you are havig, though, and the age of the computer, I am wondering if the CMOS/RTC CR-2032 +3VDC backup battery coin cell needs to be replaced.
