HP Pavilion 690-0000nf won't turn on

huuquan · ‎11-11-2022

Hi.

My computer won't start. I don't know where is the problem.

When the first connection, the light and fan turn on for a while then go off immediately. After that, it won't start up anymore.

I tried to figure out the problem by unpacking the hard disk, CD/DVD drive and an additional SDD. The computer lit up with a bunch of beeps.

I put in below 2 videos of the issue.

When the first connection

While unpacking HDD, CD/DVD drive, SDD

Can you guys tell me what is the problem ? I think it's maybe the power supply, but i'm not sure.

Upgraded hardwarehistory : an additional ram + an additional SDD.

Thank you in advance.

P/S : sorry for my bad english.

Thank you for your comment.

You're right that the beeps are about the memory issue. In fact, after unpacking the memories, i didn't put them again correctly. But it has not resolved the problem yet.

I have unpacked the graphic card and mount the screen to the HDMI of the integrated VGA of the motherboard. And when turned on, it could boot the screen and run for about 10 seconds and then turned off. See the video here

I put on the VGA card and turned the computer on. It could run for about 2 seconds and didn't boot the screen.

ok

but at this point, you should reinstall the original memory, and remove the added ssd!
moreover we now see a keyboard error!
Hoping that having installed all this incorrectly has not damaged anything!!

Yes. I have removed all the additional items and let just the original memory run. I have installed the keyboard after the error message. The screen could boot for about 2 seconds, then turned off.
