Computer won't turn on, USB has power, PSU is good.
My computer randomly shut off the other day as I was unplugging something from a front USB port, and won't turn back on. The mouse froze for a few minutes, but the clock in the corner kept running. Then, it just shut down without warning.
I got the PSU tested and it is good. I have had this computer built for 5+ years with no problems like this.
**The little USB stick for my mouse has the light on... does this mean the motherboard is ok? **
I am at a loss of where to check for anything right now. Everything was working fine. I double-checked connections and made sure stuff was seated correctly, and even unhooked the front USB ports from the motherboard and took out the CMOS battery for awhile. I also tried unhooking everything except for the power supply, motherboard, ram, and cpu.
Thanks in advance for any help.
