Older Mobo or CPU setup failed to boot and lights stopped working.
Hello! I found an old motherboard and CPU setup from an HP desktop around ten years ago. It seems to be a HP Pavilion 620887-001 ALVORIX RS880 785G SB710 Socket AM3 DDR3 board paired with an AMD Phenom II x4 chipset. I also acquired four 4GB Vengeance RAM sticks at 1600MHz. These parts have been working well together for about seven years. Recently, I purchased a PowerSpec 650W power supply and a Montech AIR 100 case, along with some WD 4TB server drives from a box I bought last year. The issue is that the system won’t boot at all—no power indicator lights up above the RAM. I’ve tried checking each connector to see which might be the power source, but so far nothing has worked. I attempted to start the PC by opening the case and testing the connectors, though no fans are spinning. I’m unsure if I made a mistake or if something is incompatible, or if one of the components has failed after being stored for a while. Any suggestions or information would be greatly appreciated.
Check the coin or button cell in the Mobo. It's likely a CR2032, but it's better to get a replacement that matches the original specifications. I can't see the battery label from the photo and there aren't clear details online for this model.
Great job on the clean, dust-free setup! The white fan case design really enhances the look of your old system.
Hey! Sorry about the failed battery swap. I’m planning to test it with a friend’s motherboard and a new CPU, hoping it goes smoothly.
Switched Mobo/CPU/Ram to AM4 instead of AM3 and the fan didn’t start. Checked PSU, bought a faulty one. Fans spun once but refused to run the system with onboard graphics. CMOS reset didn’t help. Planning to move GPU into BIOS for on-board graphics control.
