ATI RAdeon Saphire HD3650

I have a SOny Vaio PCV RS420, 512mb RAM (will upgrade) A pentium 4 2.8ghz Hyperthreading technology, a AGP8x slot, a 550watt PSU.

I bought a ATI Radeon Saphire HD3650 512mb ddr2 that fits a AGP8x slot and lo and behold it doesn't work. The fan on the card spins but no picture shows up on the monitor. (NO I do not have onboard graphics) My old graphics card a ATI Radeon 9200 (works) no problems with the old one. I tried some things to see if it was a defect in the card. I can connect to my desktop via my laptop. So I can put my old card in and unplug the VGA cable and see picture from my desktop on my laptop. If I put the new graphics card in I cannot see picture on the monitor nor on my laptop (black screen of death) it acts as if the pc is off. Now, I know the computer boots up but it will not recognize the graphics card. Is it my motherboard not compatible or the graphics card or not enough RAM?

Here is a video of what I am doing and what is happening

Yes I did because if I wouldn't the computer has critical beeps and shuts down.

it shouldnt be.

sorry to say man but i had a similar problem with my old AGP system. nothing showed on the screen. it turned out that my graphics card's agp interface was too new for my old agp motherboard.

Ok guys I found a AGP update specifically for my motherboard hope it will work.

I am not sure, I think a part got cut out or something. I did because if I wouldn't it would start to beep. It is a 4pin that connects through molex

Who's drivers are you using? Make sure you get the drivers from Sapphire. AMDs drivers won't work.

Geo, your close but not quite there. On a 32bit version of windows, address space is reserved starting at 4GBs and working its way back. This means 3.75-4GBs might be reserved for the video card, 3.5-3.75 for I/O, etc. His 512MBs of ram starts at the beginning and won't be touched. (unless he has more then 3.5GBs of space that needs to be reserved.)
