Looking for Answers about samsung 215TW?

I have a Samsung Monitor 215TW. I had to reinstall Windows on my computer. After updating Windows XP to the most current service pack, I used the original CD to try to install Magic Rotation and I got an error message that the operating system didn't match.

When I wake my computer from sleep or if I turn off the monitor for a long period, I turn on/wake up to massive flickering for about a one minute and then it stops. What can be done to fix this?

I have two 215TW monitors that I have owned for about 5 years. Both monitors have developed random vertical lines in various colors. Is there something wrong with them? Do I need to replace them? See attached photo.

I'm expirancing an issue with my SamSung 215TW. When I have it connected to any PC. it will not get the siginal. It acts like it is as the blue light for power stays on instead of blinking. I have tried the source button, I have tried the auto button and nothing works. When I do hit the source button I get a message that says Analog signal. I can press any button and nothing happens. I can;t even see the menu screen. Can any one help with this problem.
Thanks,

Using IMac and 215TW as secondary monitor.
Monitor flickers terrible and then it good for some time but when ever
the monitor goes back in "sleep mode" and comes back it takes 5 to 10 minutes before
I can see something.
Sometimes the monitor goes total black and I have to turn power off and on to get it back to flicker.
Then again 5 to 10 minutes and sometimes I can see something. Most times I have to turn it on and off multiple times

Is there a software driver available that will allow me to use my 215tw monitor with Windows 7? The most recent driver on the download site is from 2006 and that was before Win 7. Thanks.

Everytime I plug my 215tw monitor into my windows 7 laptop the laptop screen goes black. I can hear the login etc come up but nothing shows.

I have small lines at bottom of screen and the go up about 4 inches across the entire screen.
How can I get rid of these lines?

Are all the features of my monitor, model 215TW, compatable with Windows 7?
