My PC reboots for no reason !

[mrwolf]

Ive just built my new pc and have had no problems untill i put in a new case [i-cute].

Spec

CPU : P4 2.4 HT 800fsb
MB : ABIT IS7 800fsb AGP8
RAM : DDR PC400
Graffix : GeForce4 MX440SE 128mb
HDD : 2x Maxtor DiamondMax 8 40gig mounted vertically
CDrom : 1x Liton 32xCDRW 1xTeac 40xreader
Cooling : 2x exhaust fans [1x led] Intel CPU Fan + DDR Heat Spreader.
PSU : Q-Tec 450w Dual Fan Gold
extras : 2x Cold Cathode tubes, digital temp monitor

The rebooting happens at anytime dont need to be playing a game or anything, I havent set the bios to reboot or shutdown at a set temp and the cpu temp is a steady 37-38C while typing this message. Rising to 45-48C when playing BF1942 set @ high quality so im sure its not a cooling thing.

Hope some1 can help me its driving me mad and the is irony as i built and sold 2pc's to buy this new one for me and they work with no problems at all so it makes it twice as bad that my super new one doesnt

Check your power supply. They do that as they go bad.

power supply is one day old

lol...then I doubt it is the powersupply unless they gave you a bad one! Your motherboard may be set to reboot when something is overheating or something but Im not really sure
