|"so my computer won't turn on at all, it just says the hard drives not found..?"|
It obviously turns on if you're getting an error message. I bleieve what you mean is, it turns on but won't boot into Windows?
"I can answer any questions to anyone that can reply"
You can start by telling us what you were doing the last time you used the computer...did you make any changes? install any new hardware or software? And how about listing the system specs? If it's an OEM system (Dell, Gateway, HP/Compaq, etc), post the make/model. If it's a custom built system, list the make/model of the motherboard, CPU, RAM, video card, HDD, power supply, etc.
