Computer stuck in bios while booting up

ive had my xps system (windows xp)for six weeks now and for the last two weeks the system sticks on bios when booting up.the only way i can get the machine to load windows up is by switching it off then quickly switching it back on again.i have emailed dell about this and get an automated response saying they would look at it .had NO response and this has happened three times now.phoned dell up was waiting on the line for 40 minutes to be told the queue had closed lol.whats up with my machine?

also my dell mouse keeps going into a spin whats up with that?should i have gone to my local computer store for a system instead?:smileymad:
