Greetings

I have had a problem with my computer since I got it nearly 2 years
ago. I think it is some sort of device driver problem but i haven't
been able to diagnose it. I just did a fresh reinstall of winxp and
that hasn't fixed it

problem is VERY slow boot process then occasional spontaneous reboots
during the boot. if i just keep rebooting then eventually is starts and
everything is fine. it usually doesn't crash and can go for a few weeks
without needing a restart

i have all the latest drivers from manufactureres website

i have a tv card but the drivers aren't loaded and i don't use it

one problem i had this morning - i put a dvd in and it went to a stop
screen with "driver_irql_not_less_or_equal" and lower down "cdfs.sys"
but when i restarted it actually started first go (though again, very
slow boot process), and here i am using it with no problems. It
occasionally freezes using moviemaker 2 but doesn't crash the machine -
just have to restart moviemaker

I can always boot to safe mode. I can do everything i need to on this
machine without it crashing - i use paint shop pro, office 2003,
opera, other apps and the list goes on

i'm keen to try and diagnose this problem - sometimes i think it must
be graphics card, other times maybe motherboard problem

if someone can help me with where to start i would appreciate it as I
want to shut down sometimes but dread the start up process

many thanks
