I just purchased a new video card, and am having a very hard time figuring out why it will not work. I'll try to give any and all relevant information, but let me know if I leave something out. I'm pretty experienced with computers, building them, diagnosing them, etc., but this one has me stumped. After seating the new video card and making sure all of the proper cables were connecting (including the four pin peripheral power cable) and everything was connected, I powered on my PC to find no image, and the CPU fan spinning out progressively faster and faster until it reached it's maximum speed, and then staying there. Previous Card: Nvidia GeForce 6700 PCI-e x16 256MB New Card: ATI Radeon x1650 PRO PCI-e x16 512MB Power Supply - 350W (what is reccommended) CPU - Pentium 4 3.4Ghz Chipset - Intel 925xE The reason I purchased the new card was because my old one's cooling fan just kind of died on me (and then actually fell off on its' own). So after failing to install the new card, I plugged in this golden oldie to have some kind of computer access, but can't do much of anything besides surf the internet/word process etc. I just bought it today, and I'm really hoping it's not a bad card, because I had to snip off about 4mm's off the bracket to make the card fit in my case, which I'm 99% sure has nothing to do with the card not working, but I'm also 99% sure they won't take the card back or provide me with my warranty. Any help whatsoever will be much appreciated!!
