1. Verify it is plugged in.
2. Press power button.
- does your power supply have a switch on it? Look for a black rocker switch
3. Do you hear a beep?
4. If you hear a loud continuos beep, power down the Machine and unplug it.
5. Hold power button while PC is off, it may come on for a second.. This is called "bleeding the capacitors"

8. Plug in power cable and start computer with one stick of RAM, problem solved, you have bad ram.
9. Remove all PCI cards, and cards that are in the back of the computer. Remove them from the white slots, there is a small screw on the side near the back of the computer to unscrew, you will need to remove a small black door that holds the cards in place. BE SURE power cable is unplugged.

12. No light? You need a new power supply. There are 4 screws on the outside of the case where you were plugging and Un plugging the power cable. Remove screws and remove power supply, you will need to disconnect all connections. Type any and all numbers into an Amazon search and spend the $25, Amazon is safe.

How to installing the windows 7 in optiplex 745
Installing windows 7 isn't difficult. First, you need the disk to install it from. If you don't have that, Microsoft no longer sells this version, so it will be harder.
If you want to keep your programs and data, there is a package, "PC Mover" that you can buy that will help you preserve all your data and programs. I've used this many times to help upgrade systems like yours.
