blue screens

Since I am working with Windows Vista I have 1 or 2 blue screens every day.

How can I prevent this?

It tells not exaclty the problem. I can not change each component of my
computer. And the messages are not always the same. I had Karpersky
Antivirus even if the programm is not installed. The blue screens are worst
then with Win 98. What can I do?

Best regards,

Blue screens more often than not are related to things other than the OS
itself.
Common software issues include corrupt video drivers, too many poorly
written background processes, a poorly written program seeking memory it can't
have or not letting go of memory.
More common hardware issues include failing hard drive, failing power
supply, less likely bad RAM.

run a thorough scandis
run a memory tes
update all hardware driver
update vist
