No Signal with GPU Installed

[desolit]

I’ve repurposed a computer. Upgraded ram and HD. Newer GPU was working pre-upgrade. Now:

• black screen through startup connected to the onboard graphics. can’t get into bios or safemode.
• remove the gpu and everything works as it should using the on board
• with the gpu installed: no signal from the vga port, eventual signal from the hdmi port
• reset cmos
• deleted gpu, reinstalled drivers, looked for updates, everything is current

This is a crap computer for my kid to play Genshin and Zelda on. So the specs are all within range and this was supposed to be budget friendly.
Thanks for any help

Tried that. No change

Not all new parts work in old systems.

Also the recommended psu wattage is 300 watts.

Also the recommended psu wattage is 300 watts.

Im going to borrow a larger psu to test, I’ll get back to you

[Rustys]

just because it says 300 does not mean that it can produce that.

[PeterOz]

what connection does the monitor have
You say you can’t get connection.
Then you say you get hdmi.

• with the gpu installed: no signal from the vga port, eventual signal from the hdmi port

[desolit]

I’ve tried multiple monitors. The one I will be using has HDMI and VGA conections

[PeterOz]

I’m still confused
Yous say

eventual signal from the hdmi port

So does it work on hdmi?

[desolit]

Yes, but not until it’s at the login screen.

I have a 400w psu on it now and there is no change.
