My HP pav will not restart from restart button in windows

[Guest]

My computer boots fine if I power of by holding the power button .
It goes straight in to WIN XP no problem.
Press restart or a program needs to restart the computer gets to the HP page
with boot options and just hangs 20 minutes later it may have loaded.
If I press power button off and power back on after a minute we get going OK
again.
I have checked seagate drive it passed on seagte site removed cmos battery
checked motherboard, everything.
Is this a fault of one corrupt windows file that only is used on a restart.
What is the difference between a restart and total boot up??
Any help will be appreciated.
I really do not want to use the recovery console on the hard drive it means
loading all the third party software again.

I had a problem once with a HP Pavilion not restarting after a throrough
disk check due to an old version of nVidia driver. Have you checked HP.com
for your particular model of Pavilion to see if there are any help documents
relating to this problem/issue? Is it a laptop or a desktop machine? You may
also want to check for HP driver updates at their site.
