Computer keeps re-booting automatically after installing GeForce 7300G

[headshooter0912]

Hi, i really need help on this one. My computer keeps re-booting automatically after installing GeForce 7300GT AGP card.

I have been using this card for quite sometime now, however recently this re-booting problem started. I got the card replaced with the same one thinking the problem might be with the card. In the meantime i installed a standby Fx 5500 AGP and it worked perfectly.

My system configuration is:

Windows XP Pro
P4 3GHZ
1.5GB ram
400GB HDD
300W PSU

does your computer beep? there's a sequence that will tell you what's wrong, like morse code almost. anyways, it could be a number of things, not enough power, not plugged in all the way, try resetting bios.
