Question My pc is dead

[Seman Hipster]

It just work before I change the CPU cooler, and added sleeved extension cable. it posted for a while then the pc turned on and off for a continuously and consistently, then the motherboard check light flashed CPU, and I took out the 8 pin CPU cable and used the original cable. then it just won't power anymore. everything is working fine but it wont just power. when I take the power cord out and put it back on the motherboard flash for a second and just wont work at all afterwards. I don't know if the motherboard is dead or not.

Are there more sleeves than just the cpu cable? If so take off all the extension cables and use the power supply’s plain cables. See if that works. Make sure your cpu cooler is plugged in correctly. The system might not boot if it detects no cooler not sure. If that doesn’t work look for bent pins.

yes i already used the plain cables and it wont even start, like there is no power. and the PSU is definitely not at fault
