Moniter flashes off
When I turn my computer on, My MAG 19' monitor (about 2 1/2 years old) somes on for MAYBE a second and goes black. When I turn the monitor off then back on, it comes on for a SECOND and black again. I can click on something right away and when I turn it on again, the same or new screen is up...so it is getting feed from the tower, it just will not stay on. I am on a frineds computer right now as I cannot see my screen long enough to do anything. I am not sure i entered the correct/ product as I am not at home.

A lot of times this is caused by bad caps on the power board, at least with certain other brands. Mine did this when I got it as a DOA donation. If another monitor works fine on your PC as suggested, it would be worth your time to open up the back and check for any capacitors that are swollen on the top or bottom or leaking (worse). If you don't want the hassle of replacing these or are unsure of how to solder/desolder, please don't just throw it away... they are filled with mercury vapour and should be disposed of properly, or FIXED. There ought to be someone local who knows how to do this... if not, hit me up.
It may be sensing a sync or timing problem. If you've recently changed your resolution, (or if a virus did that for you), the monitor might not like it, and will turn itself off to protect itself from over-clocking on a mode it can't handle.
Try booting in safe mode, and see if the monitor cooperates. If so, you can then change the resolution to something a little lower, in hopes that it is supported.
Try borrowing a monitor - if the borrowed one has the same problem on your pc, it might be a problem with the video card instead.
