Hi.
After scouring the forums for quite a while (but probably not enough), I wonder if anyone has any experience properly diagnosing a PSU or MB failure, or a BIOS problem.
The symptoms:
When switching on the PC, the PSU (Corsair 750 RM) starts to make a clicking noise about once every second.
The CPU and case ventilators work and the drives spin up: Just no image, no keyboard lights.
When I detach all PSU connectors and leave just the ones for the MB (Gigabyte GA-Z97-HD3), the clicking sound is there:
When I detach just the PSU connectors for the MB and leave the others, the clicking is gone (I power up the PSU through the paperclip trick).
What preceded:
A couple of months ago, I replaced the old PSU by this new one. Worked fine till now.
A couple of days ago, I decided to upgrade my antique GT640 graphics card to an RTX3060 Duo.
After inserting the card and connecting it to the PSU, I power up the PC and get a solid red light near the card's connector and no signal out of its HDMI port. I decide to wait for my order of a DisplayPort cable to arrive, the next day. In the mean time I reinsert my antique graphics card and decide to update the BIOS (never know).
I reboot with the new BIOS and all works fine. I quickly check the new card again to see if that helped, but same problem.
I then reinsert the old card and continue working, having decided to wait for the DisplayPort cable. All works fine.
The next day, I fire up the PC again, having changed nothing in the mean time, and the PSU appears to be clicking like clockwork. No display and probably no POST either, since no beeps (although I'm starting to doubt now that there were in fact a couple of beeps during the very first power up that day, but hadn't really paid attention).
Anyhow, now it's like described in the symptoms above.
A bit of TL;DR, I know, but if anyone has any idea how I could proceed from here, any hints are very welcome.
Thanks,
Dom
