One of my HP computers has the same problem with the Ati radeon 7000 64 ddr card. When u put it in, he computer just freezes at the HP logo, like ur computer and the e-machines logo. The computer also has the Intel 810 chipset. After looking at the HP forums, I found out that NOBODY has ever gotten the Ati Radeon 7000 64 meg ddr card to work. You could be having the same problem. Many ppl think that it is either a PSU problem or a motherboard incompatibility. I believe it is a motherboard problem b/c I got a Voodoo 5 PCI running on that computer and I know Voodoo 5s use a lot of power. The problem w/ the HP computer, and probably yours, is probably a motherboard problem. Try getting a new Bios for the motherboard. If none is available, try getting another PCI video card. If you need a 64 meg card, and ur motherboard is like mine, u should get a PNY Geforce2 MX400 PCI card. That is the only brand of Geforce2 MX 64 meg cards that is confirmed to work on the HP computers (I have no clue why). 32 meg SDR cards should work fine also.
