I hope this makes your card work. Now I'm sending you two zip files. The first one contains the win98 boot files. Extract it to the desktop. Now, download- http://www.softpedia.com/progDownload/HP-USB-Disk-Storage-Format-Tool-Download-123786.html
Put the usb pendrve in, open HP Format Tool. Select your pendrive at the top and then under File System choose FAT32, now tick both as sgown in the picture below. Then Browse and select the Win98 folder that you had extracted to your desktop earlier. No extract the Nvflash zip file to the pendrive. Now copy the Gtx 570 bios file to your pendrive. Rename the bios file to something simple, like gtx570 cause later when you falsh the card you will have to enter the name of the bios. Now it should be stored as gtx570.rom Restart the computer and makes sure to keep the pendrive as the primary boot device in the bios. You need integrated graphics and make sure that in the bios the primary display is set to integrated graphics and not the Gtx 570. But when flashing the card the 570 must be in with all power connectors on. Now you will now be in DOS Mode. Enter the following command without quotations please.
"Nvflash -4 -5 -6 gtx570.rom" Now hit Enter. It will now ask you to press "Y" to confirm. Do as follows and then restart. All done and working Gtx 570
