shrinking and twisting screen

[wadada]

Good day all,
This is too technical to report here, all the same I still feel some 
of you might have experienced such problems to offer some help. For 
the past four weeks, my screen SHRINKS and TWISTS in the course of my 
working sessions. At times all the characters blow up very big on the 
screen resulting in very small part of text on the screen. When this 
happens and I turn the monitor power on and off, everything comes to 
normal. I am still capable of working alright and don't loose 
anything when it happens only that it the screen appears very nasty 
and undesirable. This problem occurs in DOS,WINDOWS,and UNIX.

This problem occurs so often in the course of my working hours that I 
can't hang on for so long. I took the whole system back to the 
company and was tested for seventy two hours but this problem never 
happened. I was therefore convinced that all was over but immediately 
I brought it home and started working, it come up again! This has 
made me conclude that it might not be a technical problem but 
environmental. I am still looking round for cure but I will 
appreciate it if any of you can be of any help.

Thanks in advance
