Question No Signal to monitor

[Notoriouss21]

Hello guys, i am trying to fix a 12 year old PC that was sitting for 2 years now. The problem is that the computer used to work fine until 1 day it stop sending signal to monitor while everything lights up and starts up fine.

I have also taken out GPU and tested it on my main system and it worked fine sending signal to monitor so my other option was testing RAM with MemOK button on the motherboard and it booted fine with no red lights.

I cannot test the ram on my main system because this is ddr3 and my main system takes ddr4.

So my question is could it be the old PSU that struggles to send signal to monitor because when i plug hdmi into the computer my monitor reacts but shows no signal - turning off.

I'm gonna go with yes but while that's on the table could I have a Spec Sheet of the system while we're at it?

I mean if your PSU is at least 750-800 you should be fine......................................

That little circle battery is the battery for the CMOS. The fact that it was 12 years old would be reason enough to point to the battery as a problem.

this pc stood in dust for 2 years. Thinking it was probably old PSU after not finding any clues on the internet i gave up. And now again i looked up on so many places and none pointed to the lil battery. Everything was about monitors, hdmi, gpu and psu🤣
