Hi all, found myself needing some help from the community! I've been a long time visitor to techpowerup and used it many times to solve my problems but this one I can't seem to get around at all I bought a VTX3D HD 7750 1gb from ebay a few months ago, worked okay but the dvi output never worked with my pc screen, I could use the vga and hdmi to connect to my television fine. To cut a longer story short I decided to try flashing the card incase the bios was a bit dodgy so (as per usual) selected one from the techpowerup database (of which only 4 7750 bios's are on) and flashed the card using atiwinflash. Now the first time it threw up an error then said flash complete. Without wanting to kill it I reflashed it and this time seemed to go through and reported successful. Restarted the pc but wouldnt boot with the 7750 as primary display adapter. I can use the igp on the board the card was on and 'see' the 7750 in device manager but the atikmdag.dll blue screen gets thrown up if I try to install drivers (on an xp machine) gpu-z reports the card as a 7750 but various details are missing or incorrect. Using the card as a 2nd gpu on my main machine I can again see it in device manager but cannot install drivers properly and has incorrect details (win 7, atikmdag.sys error)I decided to try to flash it the proper way via the usb flash drive and atiflash. I've re-flashed it with all 4 of the bios's in the database but all continue with the same error. Can anyone out there either get me the default VTX3D bios or know where to get it from? I've emailed vtx3d themselves but doubt they will answer. I'm sort of out of ideas now but this is the only thing I can think of as the card is the low profile version with hdmi-dvi & vga where as the other cards I (expect) are full width and different outputs. I did wonder if the powercolor bios would work as they also do a low profile with matching outputs? http://www.vtx3d.com/products_features.asp?id=120 I Know I should have backed it up first but sods law that the first time in 8 cards I've flashed it decides to fail Thanks all After further looking the club3d 7750 lp may also have a bios suitable aswell as the HIS HD 7750 iCooler 1gb LP edition if anyone has one?
