I am unable to turn my computer on. There is absolutely nothing happening When I turn on the computer (by pressing in a button), the monitor will react with a green light on for 2 seconds and then the green light is off. No lights to indicate the computer of disk drive are on.
I recently had a problem turning on my XPS 200. Then I fixed it by placing my right index finger in the slot and behind the on/off button. Then used my left index finger to push the on/off button from the front. Pushing the button from the front against the finger from behind created enough pressure to turn the machine on. Sometimes I have to push the button from behind to the front and vice-versa to get the computer to turn on. It's a lot more work, but will have to do until I get a new hard drive, preferably not Dell. The hard drive is making a lot of noise and recently a CD got stuck in the CD slot and wouldn't come out until I rebooted.

The monitor is not receiving signal from the computer. Is the power light on on the computer? If so - press and hold power button on computer until the power light goes off, then press again to restart. If the computer starts and you still have no picture it is most likely a video card or motherboard problem.
I didn't have the monitor connected to the computer, and that's why the power button was unresponsive. After connecting it, the solution above worked for me.(My KVM switch was set to a computer that was turned off)
Ensure the video cable is connected (and connected to the correct video port).
Turn off the monitor using the monitor's power button and then restart the monitor.
Cycle the power on the monitor as follows:
Turn off the monitor. The power light on the monitor should be off. Leave the computer turned on.
Unplug the power cord.
Wait 5 seconds.
Plug in the power cord.
Press the power button on the monitor to turn on the monitor.
One of two things happens:
The image from the computer displays on the monitor and you can use the computer again. This indicates that the monitor was unable to detect that the computer had awakened from suspend mode. Turn the monitor off when it is not being used or disable suspend mode. For some computers, updating the BIOS corrects these types of suspend problems.
The power light on the monitor comes on but the screen displays one of the messages again. The monitor is not receiving a video signal from the computer that it can detect and use. Continue using these steps to adjust the Windows display resolution to the Monitor's native (default) resolution
Connect the monitor to another computer that you know is working to determine if the monitor should be serviced or replaced:
If the monitor displays an image from another computer, you know that the monitor works. Troubleshoot the video connection and graphics adapter on the computer.
If the monitor remain blank when connected to another computer, the monitor signal processing hardware may be bad. The monitor should be repaired or replaced.
