The Questionsystem requires removal of the CMOS battery to boot.
The Questionsystem requires removal of the CMOS battery to boot.
the explanation comes from the fact that it doesn't start up properly even without the cmos battery, but it still allows me to access windows after a lot of difficulty. Last time I powered on the machine it didn't display any image and it was stuck in a boot loop, flashing the power led two times with a 2 to 3 second pause before fans began spinning, but the power led activated slightly later after components started, taking about four seconds. After waiting around four minutes (the system could reboot during that time or not), it showed a message indicating incorrect cmos settings because I removed the cmos battery (it wouldn't reach it without it). Then I entered bios to reconfigure and save. Even after saving, it still took longer than usual to boot into windows, and if I shut off the pc I have to repeat the process to get back up.
Things I attempted:
- changed cmos battery
- cleared cmos
- updated bios
- installed ram one by one on each slot
- tried different pcs
- booted without any peripherals
None of these fixed the issue, so the last attempt was replacing the motherboard and cpu, but since I can still boot into windows and use it, it seems unrelated to the cpu itself. I even played games briefly but encountered a BSOD eventually.

I'm not sure, it seems like the case power switch was faulty. I turned the PC on using a screwdriver and everything looks fine so far. I'll let you know if anything changes again.
When sharing a troubleshooting thread, it's important to provide detailed system specifications. List them clearly as follows:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
Include the age of the PSU along with its make and model. Also mention the BIOS version for your motherboard at this time.
Test three different PSUs.
List all the makes and models of the PSUs you've used for troubleshooting, and note their ages if applicable.
