dell inspiron 1420: can't sleep to blue screen

i've posted in other forums about my problems and i haven't any real solutions yet.

i barely had my laptop for 2 months and i already have problems. so far i've been dealing with these issues:

1. can't revive the laptop from sleep mode and had to manually turn it off. as far as i know, it's either the critical updates from microsoft or a vista thing. i figured that microsoft will come out with an update to fix all that.

2. the laptop would unexpectedly freeze, i've tried to wait it out and eventually i'm forced to a manual shutdown.

3. the first time i used my webcam, the blue screen flashed and rebooted the laptop. is there an update for the driver?

i've run the dell diagnostics and it came out clean, so i know it's not the memory. any ideas? any help would be greatly appreciated.

my specs: windows vista- home premium intel core 2 duo cpu [email protected] 2.99 GB RAM mobile intel 965 express chipset family any help would be greatly appreciated.

 

Did you install any drivers right before the symptoms started to appear?

 

I have solution for #1. Try to search the forum for Bluetooth sleep problem. I have followed the instruction and it works for me so far.
