So I've had an issue the past few days, so I thought I would try here. My computer first of all isn't a great one, it's about 7 years old and wasn't made for gaming, although it works fine for most games besides having a sub par graphics card. Anyway, we have to take it out every 6 or so months and clean it up with some compressed air, so my two thoughts are that it something either got misplaced while cleaning it a few days ago, or it just finally decided to die on me. I'm not confident it has died yet, because it was working fine with no issues the days before cleaning. When I press the power button on my tower, it will boot up fine, you can hear the fans running and a little click, where usually the monitor will turn on, along with the mouse having a red laser coming from the bottom. Except, it doesn't. The mouse may shine a laser for about a second before dying out, and my computer monitor won't turn on unless I forcefully press the power button on it, which it will not find a signal and go back to sleep automatically. I have tried forcefully turning the tower off by holding in the button, unplugging everything, and even taking it out, opening it up and making sure nothing was out of place or unplugged. As far as I can tell, nothing. So, I plugged everything back in and gave it another shot. I think something in my computer isn't giving my ports power like it should, or very little (which is why the mouse would click on for a second on one of the USB ports) Is there anything you can think of that might be causing this, or any possible fix?
My guess is the USB ports or the PCI ports that you have your things plugged into are dying / not getting the power needed to run. This was the first issue I started having when my rig died a year or so ago.
Does windows device manager detect the mouse ? With a PC 7 years old your motherboard's USB bus is probably dead or dying. If it detects it, then its probably a driver issue, if not either your mouse cord is broken or your USB bus is dying. Should look something like this:
Oh, this has fixed itself. Computer and mouse working fine now. I think some power outages gave it some issues
