Computer won't go to sleep
After I restart my computer, the sleep function works fine. But after a certain length of time (8-12 hours?) or a certain number of sleeps (2-3), the computer stops going to sleep. This problem started recently, when I had to have my hard drive replaced due to the USPS' bad shipping. It didn't start immediately, however, it only began after a few weeks or a month.
When I try to make it go to sleep, either via the power button (when set to sleep), the sleep button in the start menu, or the sleep key on my keyboard, the screen does the fade to black after 0-2 seconds. Then, after 3-5 seconds of black screen, the screen just turns back on again.
I have tried setting my network card, mouse, and keyboard to not wake up the computer, I have tried disabling sleep timers, I have tried hibernating instead of sleeping (which has the same effect). I have tried closing unnecessary processes such as autoupdaters in the task manager. I have tried scanning for viruses with AVG. powercfg -lastwake doesn't show anything (probably because the computer doesn't go to sleep in the first place, even for a second) The only thing that works is restarting the computer, which is only a temporary solution. Any help please?
