Hi,

My CPU makes long beep sound continuously and my monitor is not turning on. The error message says, "no display". It is sure that monitor has no problem but CPU has something wrong.

Please help me!

Hi,

Please count the number of beeps before it stops and starts back, or if you don t feel doing that, follow this. Sorry to say, this will be a fairly lengthy test. What you need to do first of all is boot up your computer with:
  • CPU installed
  • NO sticks of memory (RAM)
  • NO hard disks / storage devices
  • NO peripheral cards on (PCI-E/PCI/AGP/etc). It means no video card too if you're not using an on-board one
  • Literally just CPU and motherboard connected to the PSU


You must also disconnect the power supply cables form hard disks/storage devices, as a PSU will cut off power if a peripheral component like this has a short circuit happening.

Please ensure data cables are also disconnected.

Good luck!
