9800gtx+ drivers freeze windows XP

I bought an Inno3d 9800gtx+ Freezer DHT yesterday. I installed windows xp service pack 2. after that i installed my motherboard drivers and restarted the computer. Then i installed the graphics card divers from the CD(v182.1), restarted the computer.Now this time it freezes when it logs into windows. the drivers have slightly worked because the resolutions have increased but thats it. After 5 seconds of logging into windows it freezes. ive tried intalling the latest drivers from the nvidia website(v182.5) but it still has the same result.Ive also tried v178.24 with no luck. I had to use driver sweeper to remove the drivers so that i could use windows again and type this email.This is my first pc ever and im already experiencing these kind of set backs. i dont think its a power problem because people with 1000w psu are experiencig difficulties too.

PLEASE HELP ME. I JUST WANT TO GAME.

cpu: AMD 5600+
