when I press the power button nothing happens.

"Hi guys, I have the exact same problems. I have checked the psu and power connectors, and the front card power button, they are all fine. The bios chip gets really hot though.

What can I do？

thanks"

Replace the motherboard. It'very easy. While doing that add 3.8 processors and AMD 5450 video board. Put all 4 gigs of memory. Add 1 terabyte hard drive. Install Windows 10 and you,'ll have a nice running computer. But the motherboard alone will solve your problem, You can get them cheap on EBay.

I’ve had the same problem and I have a answer for it. There should be a green pin inside and if it’s on the “RTCRST” pin move it to the “PSWC” pin and that will work.

Brother this is problem of your front Power panel card unplug the front button power card and on PC directly or replace front card of power!

check processor chips
