vista crashing on bootup

vista is crashing on bootup. sometimes it hangs with a blank screen
before the login screen, sometimes i get to the login screen but then
the screen just corrupts with lots of lines across it.

i can boot it up in safe mode with or without networking, and with
networking i get wireless access through to the internet ok.

in the event viewer, i can see many error level problems:

event id 4609 - com+ event system detected a bad return code.
event id 7001 - lots of these for different services. i get "the
dependency service or group failed to start" or "a device attached to
the system is not functioning".
event id 10005 - dcom error 1084 or 1068 attempting to start service.

i think it's network related. network list service, tcp/ip registry
compatibility service, network location awareness service, netbios,
dns, dhcp services.

can anyone help??

thanks ian.

have a look at the tutorial 'here
(http://www.vistax64.com/tutorials/91...epair.html)and you ma
also wish to do a 'system file check
(http://www.vistax64.com/tutorials/66...c-command.html
this will normally sort most startup problems but as with any proble
this may or may not work for you.

This is normally a safe operation but I would advise as always that yo
back up your critical files before proceeding
