Just last week, my USB ports where my mouse and keyboard were connected randomly stopped working.
It looked like my pc froze, but sound was still playing and the game i was playing still went on.
at first, i thought it was the game. so i tried CTRL + ALT + DEL but nothing happened and my mouse wouldnt budge.
I had to hard restart my comp and convinced myself this was a one time thing
It happens periodically now. After im using my computer for a while like 30-120 minutes, it would just randomly stop working for some reason. I had to use the 2 ports in the front for them to work for another 30 min. But then the two FRONT ports randomly froze too, while the 2 back ones wouldnt work.
At first i thought my mouse and keyboard's plug were broken. But they couldnt be broken and randomly stop at the EXACT same time. I tested my headset mic by plugging it into the back ones when they stopped working and i couldnt talk in the mic, as if the USB ports didn't supply it power.
What i dont get is that y mouse and keyboard still lights up. Yes, after the usb ports stop working, it still lights up, meaning it's still being supplied power (although my caps lock and num lock buttons dint make my keyboard light up) But why wont it move if it's still being lit up? I dont understand. This is so frustrating to hard restart my computer EVERY TIME it randomly freezes just so it would work again
I also plugged in a flash drive into the port that was fried, and it still picked up the folders and autorun and stuff.
I have tried system restore, checked BIOS .
Things i havent done yet are re-install drivers, purchase a new motherboard ( if this is the problem), any other solution.
Please help. this is so frustrating and goes against my logic. How does one supply power and not work? Ugh.
Thanks in advance

I dnt know my motherboard because with my dell case, it's impossible to crack open without cracking open everything and it's just a hassle.
