I have a problem. My configuration : - motherboard gigabyte 890GPA-UD3H (AM3 socket) - phenom II X2 560 - 4 Go ram ddr3 kingston value - PSU seasonic S12-II bronze 430W - graphics radeon HD5770 sapphire vapor-X OC - cooler noctua NH-U12P - case xigmatek asgard
It began with my internet connection not working properly, the GIGABYTE support told me to do a clear CMOS. So following the motherboard manual I decided to remove the battery for several minutes (I could have shortened the jumper but I chose to remove the battery).
After that I replaced the battery, following the polarity.
Since then my PC won't boot.
Now to troubleshoot I've removed all the peripherals, the only things I've kept are one ram, the cpu, the cpu cooler, the PSU and a fan (connected to the cpu fan header) (to see wether it turns). I've removed the graphic card, because the motherboard has an IGP. When I plug the power cable and I shorten the power switch nothing happens at all. Neither the fan of the cpu nor the fan of the psu turns, there is no beep. In fact when I shorten the power switch I can hear a faint brief sound, a bit like the one a hard drive wich starts spinning can make (even though there's no hard drive attached).
I have an old gigabyte motherboard, so I replaced the battery to see if it was that but no. I can scent no burnt odor at all, be it on the back of the psu or on the motherboard.
I really am at a loss here, and I could use some help.
Thank you !

Based on your description of the issue, your PC doesn't even power up; therefore it won't boot.
Before removing the battery, did you disconnect or power off the PSU? If not, disconnect it from the wall outlet for several seconds and reconnect it. Then try to power up the PC.
Yes, it doesn't power up indeed.
The psu wasn't plugged when I removed the battery, but I'm not sure I didn't remove it while the psu was plugged when I tried it for the tenth time.
