Solve : Computer Won't wake up from sleep mode (sometimes)?

1.	Solve : Computer Won't wake up from sleep mode (sometimes)?
Answer» I've had this computer for several years now, I just recently cleaned it last night and have been having this problem ever since. I'll power on my computer from sleep mode and the power supply fan starts running really loud and won't slow down. It sounds like my harddrive revs up too but my monitors won't turn on and there is no response from the keyboard or mouse. The cd drive works as well in this state. Holding down the button for a few seconds to power it off doesn't help either. When trying to turn it on again it just does the same thing. I've also unplugged my computer for a few seconds and plugged it back in again but that didn't work either. The only thing that works I've found is completely unplugging my computer from all cables and clean it again. I don't know if its the ACTUAL act of GETTING dust out or the fact that my computer doesn't have any power for several minutes but this is a new issue and it has me completely baffled. I have had this problem TWICE since cleaning my computer and only when leaving it in sleep mode for several hours.
