Vista - vista boot up problem, pls help ASAP

pls i need somebody's help. i am new to this forum but i have problem with my system bootup.
my system takes too long to boot and it started 3days ago. it takes about 120secs at bootscreen alone. i believe it is not my start up programs as it takes about 3 secs to start up from login page. i donot use any third party bootscreen.
normally, my system boots in 30 secs but now i am facing a lot of problem which i do not understand. i have tried all the tutorials in this forum relating to bootup problems but found no luck. i hope somebody help me soon. Plssssssssssssssss

system specs:
toshiba, l300
hdd: 120g
ram: 1g
processor: 2 core (1.73gighz each)

System restore to 4 days ago.

thanks bill for the quickreply.
unfortunately i couldnot find a restore point for that day when i checked it. i guess it was because i installed many softwares during those days and also i have already used a tweak method to reduce the size of harddisk that system restore consumes.
pls how can u help me.
thanks

Hi jokesy,

thanks siw2,
i will try your method as soon as possible and will post the update.
thanks once again and God bless u.

siw2,
i have performed all the steps but no luck, i even used diagnostic start up and even safe mode but all did not work.
now, i beginning to attribute the problem to windows update. i could remember i performed windows update about 3-5 days ago and maybe because i don't shutdown always, i did not notice the problem.
pls i still need your help.

thanks
