HP Compaq 8200 Elite All-in-One PC switches on, no display... HELP!

Hi Everyone,

I hope someone is able to help with my issue...

I have a HP Compaq 8200 Elite All-in-One PC, it switches on (power light, mobo light, no POST) but there's no display on the screen. I've carried out the following in order to try and rectify the problem but to no avail.

- Power reset

- Removed RAM (gives continous, single beep) and reseated

- Removed & reseated PW jumper

- Reset CMOS

This model does not have a HDMI port so I am unable to check if it's the display, but when I tried an external USB keyboard there were no power lights on the keyboard itself.  I'm assuming it's the motherboard that's the culprit but wanted to get a second opinion. 

Thank you in advance!

Hi,

Try pulling out the RAM and wipe the contacts with a clean rag.

If it doesn't help, try to clean dimm slot with compressed air.

If still not working try reseat your CPU.
