Recently, my computer stopped allowing me to wake it up from sleep mode. The only way I can start it is by pressing the power button, and that doesn't wake it, rather just reset windows so it says shut down unexpectedly. I'm using a wireless keyboard and a wired mouse. Neither wake the computer. I tried a different keyboard, no luck. I checked the power management properties to allow the device to wake the computer from sleep, and they are checked. I don't know what else to do! Please help!!! (Will post system specs and keyboard and mouse if needed)
Check all your power connections inside the case and then reset your BIOS. If you are able to get into Windows repair mode, try to do a system restore to a point when your PC was still working. Lastly, install and run MalWareBytes and run it to take care of any viruses.
