I have an old 8KHA+ that's been fine for years, Rev 2.0, caps OK, Athlon\nXP 1900+, latest BIOS upgrade. It has an ATI Radeon 9700 Pro. I have an\nextra ATI Radeon AIW 9800 Pro I'd like to install, but when I do, the\npower supply just kicks out instantly upon pressing the start button. PS\nis Antec 430 True. I tried a different PS, Vantec 420, same thing. I put\nthe 9700 back in, have to unplug the ATX connector from the board, plug\nback in, presto, starts right back up where it left off. Have tried many\ntimes, nothing. Poof, shuts down before a fan even gets to make one\nrevolution!!\n\nOh, the 9800 came out of one of my other computers, known good.\n\nIs there something about the AGP on a 9800 that won't let it run in this\nboard? Voltage different?\n\nI have another 8KHA+ in another box, perhaps I'll try that one, but\nexpect the same result.\n\nAny suggestions?
