just to give you a little of my story before hand.. just before x-mas...my hard drive crashed...so far i've had this company send me 3 hard drives (that my wonderful mother bought for me for x-mas) and they are all bad...after the first hard drive i had to buy a cd rom cause that was bad...well anyway..mom-god love her- helped me out yet again and bought a tower for me from an auction site...well..i went to plug that into my monitor and now i think my monitor is bad... it's either that or the plug itself..if anyone knows please help..one of the little male PRONGS that plugs into the tower from the monitor is missing..would that cause my monitor not to work when plugged in????? if NOT...then does anyone know any deals to any computer stores where i can look for a new monitor???? please help!!!!!
