Question Motherboard not reading GPU - getting white light

[kiwithebun]

A few months ago I upgraded to an RTX 4060 from a 1070. After a few days my monitors would lose signal a few minutes after boot, but the problem was fixed by reseating and dusting my connections. 3 months later, my monitors randomly lose signal almost immediately after powering on. I swapped in my old 1070 and it worked fine, and I updated my BIOS and graphics drivers. Swapped the 4060 back in (including between different pcie slots) and now it doesn’t display any signal at all and I just get a white light on my MB. The fans however still spin so I know it’s getting power.

My only guess is that my power supply is worn out. It has more than enough capacity but it is 5 years old with quite a few hours.

Any advice on how to fix this is appreciated, thank you.

Green or grey? Try and use another PSU that's reliably built and with 750W of power for the entire system.

BIOS version for your motherboard?

Hello,
It’s grey, and it’s the latest BIOS version from October 2023

In theory, 650w is enough-ish for the system but a poor or worn out unit may not deliver enough juice no matter what it's stated wattage is.
I'm not so sure it's the power supply, as that one is not a crap unit but it is getting near it's end of warranty or is out of warranty by now. Either way, you want a reliable, 7y+ warranty PSU so you should upgrade.

Something like a Corsair RM750e? Good and not too pricy.
