Hi, I just purchased a Diamond Viper 9600xt 256mb DDR agp video card for my system. However, after I installed the card, my computer will not boot up past the POST. It will only show a flashing cursor in the top left corner of the screen and will not proceed any further. I used to have an nVidia 64mb 440x video card in there before. I remember on an older computer that I used to own, I had to play with the jumpers on my diamond card (it was a 770, I think). Now, there are jumpers on this new video card as well, however I do not have a manual to configure it (my nVidia card does not have jumpers on it). If someone know where I can find a manual online, or if someone knows the jumper configuration, please let me know. If it has nothing to do with the jumpers, please help. As far as I know, I meet all the minimum requirements. I even went in the CMOS and made sure the information was correct, as per the quick install sheet told me to do. Here is some information on my system. P4 2.0Gig processor 1 Gig DDR ram Aopen motherboard, with 4X AGP slot (1.5 volt) Please let me know if you need any more information, or if you can help me. Thanks.

It could be jumpered for 8x only, on many boards options are 4x, 4x/8x, 8x. Use google. Best

what os is this? did you uninstall the old nvidia drivers? Q-TEC 550 Watt PSU MSI VIA KT4AV-L 2800+ Barton 512 DDR333 GeForce4 Ti 4200 128Mb Aero 7 Lite 80Gb Samsung ATA133 HDD 120Gb WD ATA100 HDD LiteOn LDW-851S LiteOn LTR-52246S

Yes, I uninstalled the old nVidia drivers. I am also running XP pro SP2. Someone suggested it could be my power supply? Could this be an issue? I have a 300 watt power supply.
