Windows 7: Freezing with Colored Vertical lines

I have an issue and think noone can solve it.
This problem is randomly occured during commonly pc works such as web browsing, gaming, typing in notepad ,etc ; Freezing with Colored Vertical lines.
Somtimes this ballon appears with such a message like "Display driver has stopped working and has been recovered".

I assume the computer you are referring to is using the Radeon 6770 graphics card. If so, download and install the latest graphics card driver here: AMD Graphics Drivers & Software

Also, check that your graphics card is clean and free of dust, pet hair, etc to rule out overheating. After you have completed both of those steps, check back here with the results. If it is still freezing up and the driver is crashing, we will look into it further.

Yep, my graphic unit is ATI Radeon 6770 and its driver is up to date.
OS (Windows 7) is newly installed and updated.
I installed HWMonitor software to monitoring temprature of system parts and there was no temprature issue.
I dealt with same problem with an old Pentium 3 desktop rig was not resolved.
So please help me...

Can you locate and tell me exactly what graphics driver you are using from AMD? Version number is what I need to see.

You said you had the same problem with another system........were you by chance using the same monitor?

No, that was acer 15" and this one is LG 17" CRT monitor.

Is there any way you can test it out on a monitor you know works good?

I can test it with Samsung 32" LCD TV via VGA cable.
when this problem occured screen freezes, pc hangs and Num Lock key did not function and CTRL+S does not work for saving so current situation in any software like Adobe Photoshop CS6 and other softwares. So I believe this issue is not revelant to monitor but I'm not sure.

It probably doesn't have anything to do with the monitor if the pc is freezing, but it is an easy test. While you are running those programs, try to see how much of your resources you are using...CPU/RAM. You can open up the task manager while all of those programs are up and running to see how much it is using. Also, what temps did you get from the program you are using.

Something I forgot to ask earlier, did this issue start when you installed the new driver? Or has it been doing it since you reinstalled Windows?

Also, have you overclocked this card at all?
