Vista - sudden Drivers failure for all perpherals

Hi ,

my machne OS : Windows Vista Home Basic
for the last two days , im having different problms with drivers
before i used to connect to my nokia mobile using nokia PC suit 6.8.4 , now
when i try to connect to mobile from my Laptop , its not even recognising the
device.
whenever i try to switch on my blue tooth its prompting a message of Blue
tooth perpheral device idriver is nt found.
today i tried to connect my USb device , then its nt recognising the
device and giving error message of no drivers found either in machine or
internet.
in both the above the above cases its asking me for inserting the CD.
surprisingly the USB working with my other desktop with OS XP.

i have not done any major update r sotware installation recently,

i tried to solve it by several ways as suggested by windows help , but it
doesnt work.
So, Is it a probem with my drivers or my machine equipment(Device)?

im getting worried with my system behaviour.

i would be very thankful , if u propose me a solution to get out of this
problem .

plz reps

regards,
kiran.
