Issue with CPU upgrade occurred.
I haven’t tried it yet and it’s almost too late, so I might not be able to do it tonight. However, I’m open to trying it tomorrow. If that doesn’t fit, could you suggest the next best option?
did you disconnect the psu from the wall and the 24-pin connector on the motherboard? then pressed the pc power button. if no power appears afterward, your psu might be failed, or a component in your system is causing a short circuit. since only the cpu was changed, have you verified that the cpu pins are intact? did you unplug the graphics card during the replacement? are the ram modules properly installed? if nothing works, consider removing everything and rebuilding inside a cardboard case with just the minimum necessary components—board, cpu, psu—just enough ram, and nothing else connected to the pc. short power switch pins can be tested using a screwdriver.
Well, if that does not work and there is still no power, then I believe your PSU may be at fault. what PSU do you have? What is your system setup? And how old is the PSU?
I finished the CMOS process and everything stayed stable, so I decided to boot the system using only essential parts. I removed the RAM and GPU during the CPU swap, and also reinserted the RAM after swapping the CPU.
My new setup includes an Nvidia 1660 Ti, Ryzen 7 5800X, MSI B550 Pro with WiFi and microSD card, ATX motherboard, and two 8GB DDR4 3600 RAM sticks. The only change was the CPU—previously a Ryzen 5 3600. After updating my BIOS to the latest stable version, I made the adjustments. Edited on November 30, 2023 by Polar180
It seems the flash failed or got corrupted, possibly damaging your motherboard. You might see some activity when you press the power button. Try re-flashing the BIOS and use a different USB drive if possible. For testing the PSU, you can perform the paperclip test.
Thanks for the details. Here’s a summary of what I’ve understood:
The system runs an upgraded Nvidia 1660TI with a Ryzen 7 5800x processor, along with an MSI B550 PRO VDH Wi-Fi micro ATX case and 8GB DDR4 RAM. The PSU is a MOBO 2x 8GB model.
Issues include the computer failing to power on after an upgrade, despite changes to the UEFI and CPU. I’ve tried resetting the CMOS and re-assembling the system.
People suggest confirming the PSU connection is solid and checking for any accidental switches or loose components.
