I'm just guessing but it sounds more like the video card than the monitor, as your computer freezes. I would try another monitor, if available, to see if it still happens. I would also open the computer and pull the video card and reseat it. If it's an "onboard" video, I'd suggest putting another video card in an empty slot to see if the problem goes away.
Otherwise, I'd suspect memory, or the motherboard itself. Have you had any lightning or major power outages lately? A surge suppressor is not necessarily proof against such things, as many believe.

A line is appearing


I would try replacing the cable that connects the monitor to the PC first. It that doesn't clear the blue line, I would try if I could another monitor. It sounds like a row of pixels went out.

PC locked up.


reboot in to safe mode (follow these steps)
1. Restart your computer and start pressing the F8 key on your keyboard. On a computer that is configured for booting to multiple operating systems, you can press the F8 key when the Boot Menu appears.
2. Select an option when the Windows Advanced Options menu appears, and then press ENTER.
3. When the Boot menu appears again, and the words "Safe Mode" appear in blue at the bottom, select the installation that you want to start "windows with networking", and then press ENTER.

See if your DSL line works in that mode. If it does, then we simply need to clean up your windows startup applications.

Who is your DSL provider?

Red blue and green patterning on the monitor


You can try switching out the VGA cable (the one with the blue connectors on each end). If this does not work, try a factory reset on your monitor.

Unplug the monitor video cable from the computer. Power on the monitor and see if you get the same results. If so then your monitor is defective.

Sounds like your monitor has croaked. Borrow a monitor from a neighbor, friend or family member just to see if it works. If it works, your monitor is bad. If the borrowed monitor has the same issues then your Video Card in the computer is bad and needs to be replaced.

All of the sudden alot of red dotted verticle lines appeared on my screen and are on there constantly. Any idea what caused this or how to remove them?


Most likely if the line appear in all screens you have a hardware issue. Reseat the monitor connection, see if anything changes. If not, try monitor on another system or another monitor on this system, see if the problem follows the monitor or the system.

If the issue stays with the system, then you will likely need a new video card. If you have Intel Integrated video, try different RAM. If RAM makes no difference, a motherboard or an expansion video card will be needed to resolve.

Sounds like the monitor is going bad. I had this happen too and had to replace the monitor and it's been great since! If you can work fine, it's not the computer itself, it's the monitor.
