Strangely Screen Blinking

[Guest]

Hello Experts,

I'm post my issue again (after 2 days) cause no one responded and it's a bit
urgent,

Thank you.

I'm facing a problem on my PC,

every 20-30 seconds windows blinks like doing some refreshing.

For example when open (from tray) the date & time properties (double
click on the clock):
1) picking another month from the combo box
2) waiting 30 seconds
3) automatically returns to current month (March '07)

This blinking is obvious anywhere in windows. Another example is that
the language indicator in taskbar, disappears and then appears again.
Finally, some times when working on MS Access 2003, I'm trying to copy
a value from the datasheet of the table and paste it somewhere else.
Copy fails in first or second time.

I think that some spyware might cause this, but I have installed
a good Anti-Spyware to protect my PC. Of course not all Anti-Spywares
protect us from all spywares. I always keep it up to date.

Can you please help me with that?

Hi,

Also, I got ATI HYDRAVISION installed, but no service is defined to run on
startup.

Thanks in advance!
