Graphics Card problem?

Can anyone help me solve this?

I recently traded my Nvidia FX 5500 128MB for an ATI Radeon 9550 256MB graphics card. I only play one game, F1 Challenge 99-02. Runs pretty well on the 9550. What happens though is when I'm in middle of the game the screen just blacks out. Sometimes the screen hangs too yet you could still see a picture. The game freezes and there's this hissing and crackling sound I could hear from my speakers. This only happened when I replaced my GPU. So is it the graphics card? Hit me about several times already. I think I have enough RAM. I have 2x512MB DDR 533 RAM. My CPU is a Celeron 336.

Please help. Thanks.

Are u serious abt the cards??
The 9550 is WORSE then the FX 5500. The 256Mb increase means NOTHING!

I say, get it back, or get a better card. And a new CPU while ur at it, Celeron is not for gaming.

For now.. did u OC ur card?

I was planning on overclocking the 9550 but decided not to when I started encountering problems. Actually the 9550 scores better in 3dMark than the FX 5500. But hey, if the card's faulty, I'm getting back my 5500.

I'm planning on getting a core 2 duo processor and a capable mobo sometime in the future. The Celeron really sucks. I feel it too.

Thanks.

I never thought a 9550 would be better than anything, but there's the proof...

lol. Paul beat me to it. Yep, the 9550 is certainly better; it should overclock really well, too.

Your celeron is holding you back a little, but it shouldn't be causing crashing.

Something might be overheating, or maybe your power supply is being pushed too far.

Do you have your old card? You could reinstall it and see if it crashes...
