When I turn on my emachine computer the monitor works (shows windows logo) and the keyboard lights up but then the monitor goes to sleep mode...it works fine on my other computerit seems to be a power issue on the rear ports?
Sounds like a bad video adapter. I'm assuming your emachines has an integrated video adapter. Put in a video card (with the power plug pulled out! Touch the bare metal frame of the computer with your hand before inserting the video card into the agp or pci slot Don't touch the motherboard). If you get video, you may or may not need to install drivers after that. XP has a lot of video drivers, but lacks quite a few of them, too.

If you can see the windows logo screen both your computer and monitor is working, possible problem could be that the display settings are set to high that your monitor is unable to handle it.
Restart computer and keep tapping F8 key.
This will take you to the advanced options menu
In the list of options here choose enable low resolution mode and hit enter (you can only use your keyboard to choose - use the up / down arrow key)
once you enter windows low res mode change it to 800 X 600 and restart the computer
Once you are in the right mode now change the display settings accordingly.
your monitor is beleiving it is not receiving any signal from your pc. 1 make sure your cables are secure. 2 make sure your pc is on. 3 borrow a monitor from a freind to see if your pc is sending the signal out, if the borrowewed monitor is showing a picture, hook yours back up. 4 if still not picture your mpcb or video pcb in the monitor is bad.
First make sure the power cord is plugged in both ends (in the wall and in the monitor). When the computer is turned on, it should run a power on-self test and then beep. The monitor light should be green and then the Windows splash screen will display. If your computer starts up but the video fails, then the monitor light will turn yellow. A monitor light that just flickers and goes off is probably an indication that the monitor has failed. I usually try to hook up another monitor (borrow it from a friend) just to be sure that the computer is working.
when starting windows press f8 key before the windows logo shows up > go to safe mode > click start>control panel> display>adapter>list all modes> choose 800x600 x 16 colours > apply > close > reboot to normal xp. OR When f8 key pressed > choose VGA mode. If this does not work then change the VGA Cable (borrow from someone if its TFT to test)
I feel your pain. I finally moved my pc to a room with no windows! But seriously, try a different monitor first. See if you can borrow someone's to just try it before you do anything else. If that borrowed monitor works fine, then you know what the problem is. (Which I believe is the problem.) By the way, what started all of your problems?
The monitor setting in windows maybe incorrect. When booting up before you get the windows logo start hitting F8 and then choose safe mode. If your monitor works in windows there then check the monitors settings. You may have a driver issue or a settings issue when in normal windows mode.
