I have been experiencing some issue with my pc
When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.
but after changing the motherboard to older gen it works fine I don't know what the issue is
Did you reinstall the OS after the motherboard swap?
To me it seems like you performed a hardware upgrade, if so, we'll be seeing two sets of specs, one for older build and one for the upgrade.
