Reboot mid games

[Rockin Bassist Benji]

Hey all, right my problem is whenever i load up a game, the whole computer goes into reboot about 10-15 mins, which is both annoying and concerning, it doesn't happen however when i play Battlefield 2  ??? I'm running a 1.7 Duron with about 150MHz FSB (overclocked), 512MB PC2700, ATi 9600SE (was overclocked but reset to default, and now lower than defalt) with 2 20GB Maxtor hard drives, 1 40GB maxtor hard drive and 5 fans.

Did you try backing off the CPU speed?

Do you have enough power being supplyed to the computer?

lol its fixed! I o/ced the FSB by the 2mhz and obviously the computer didn't like it... all working now though thanks for your help.
Kind Regards
