I recently bought a new case for my PC. I changed everything from my old case to the new one and tried to turn on the PC. It starts, all fans work fine (PSU, CPU, GPU and all case fans). I see the BIOS screen in the monitor and then the PC completely shuts down.
Here's what I tried:
Changing the PSU: I had an old Cooler Master PSU that I already wanted to change because I thought it could fail any minute so I thought that it could have been the problem. I bought a new EVGA PSU, installed it, same problem, so it's not the PSU.
Checking for contact between case and motherboard: Just to make sure there wasn't any short I took out the motherboard, placed it in a cardboard and connected it. The problem is still the same.
Disconnecting my secondary HDD and leaving only the SDD with the OS: Same problem.
Resetting the BIOS: I reset the BIOS with the CLR_CMOS. I tried both the last good configuration and reset to default. After restarting the computer the problem persisted. Note that I can navigate the BIOS config page without problems; it doesn't shut down in the BIOS, but when I restart and try to boot the problem is the same.
This is my hardware:
- MoBo Gigabyte GA-970A-DS3P
- CPU AMD phenom II x6
- GPU EVGA nvidia 750ti
- RAM HyperX 2x 8GB
- SDD kingstone 512GB (OS windows 10)
- HDD Seagate 1TB (only for storage)
- PSU EVGA 500W
Any ideas? could the motherboard be damaged? Everything worked fine before the case change.
