Hi Sita, long time no see.

Before you ever purchase a Graphics Card, always check the site of your Motherboard to see whether or not the new card is compatible. I can say that this is very important, because I have had many problems like yourself. I bought a Hercules card last week and installed it, and I was getting unusual error messages, similar to the ones that you describe. The card crashed regularly, and I had to reinstall the Geforce 2 at the end of the day in order to get everything working again. I checked the website of my Motherboard, and low and behold, the card wasn't at all compatible. So, I checked the Motherboard site again and obtained a list of cards which had been tested on my board. One of these was the new Geforce 4, which I bought and have had no trouble with as of yet.

If the Motherboard's website is telling you that this new card is compatible, then all we here can do is suggest things that may help. The other replies in this thread could possibly fix your problem, or it could be one of many things.

Now, I'm presuming you've downloaded the latest Detonator Drivers. These are said to be good, but there have been reports of failure on certain systems. If you haven't already done so, download the next driver down from that, which is located at this little page. As everyone else has already said, make sure that every trace of your old graphics card is completely removed before you install these drivers, or you'll probably get conflicts.

One more thing, before you leave, and this is quite an important thing - did you remove your old device from the listings before you installed the new card, or did you just physically pull it out? Go to your control panel, click the "System" icon, go to the "Hardware" tab and click on the "Device Manager" button. Under the "Display Adapters" heading, you should see your new Geforce card. If there is another card there, right click and disable it. If you're still having problems, try uninstalling it. If you don't, it may cause conflicts. Well, at least that's what happened to mine.

Good luck, I know how irritating graphics card problems can be.
