I have Compaq Presario 2100 notebook, 30 GB Harddisk, 512 MB DDR, P4 . I am using windows XP Home (dont know the service pack right now).
I was using wireless comcast connection and it worked fine untill last sunday when I left my notebook on standby for 4-5 hours and then whenever I try to connect to internet, my computer crashes and restarts by itelf . It does give the message that 'Windows has recovered from serious error'. Its working fine when its not connected to internet. I had zonealarm installed on my computer. I ran Norton Antivirus (2004), but didnt detect any virus. I also restored the computer to a previous date, but it does not work. My friends notebook is working fine with the same wireless connection.
I dont have much technical knowledge about computers. I will be glad to provide any more information needed. Please let me know how I can fix this problem.
