Another hiccup is the connector for the PSU, but there are adapters out there.
Tried two different adapters for the connector... I came up with this after staring at the board for 5 minutes. Great idea... but no dice.
You tried all 8 combinations, right?
- Old Mobo Old PSU w/ GPU
- Old Mobo Old PSU w/o GPU
- Old Mobo New PSU w/ GPU
- Old Mobo New PSU w/o GPU
- New Mobo Old PSU w/ GPU
- New Mobo Old PSU w/o GPU
- New Mobo New PSU w/ GPU
- New Mobo New PSU w/o GPU
And it *still* doesn't work?
Maybe it's your BIOS / Windows / video drivers (video card & monitor) being corrupt?
I'd check there, starting with Windows Safe Mode.
Yes tried them all! Finished more than half a tube of thermal compound over the days trying all the combinations. How could the bios on two separate systems cause the same problem? If it was a driver problem, wouldn't the computer at least post?
or the mobo's chipset series (or BIOS) not playing nice with the video card's own BIOS (and it's addon bios initialization, in particular).
Thought about this too, but plenty of people have used that 5570, so I don't think it's the problem.
Precisely... I'm totally dumbfounded.If that were the case, then one of the versions running onboard video should work.
I'd deinstall the new GPU drivers, reinstall the MoBo GPU drivers from HP's website, clean up the BIOS, and see if Windows Safe Mode could get it to work as VGA.
Still don't see how drivers can make a difference. I haven't installed them anyway. Also, I've tried every combination in BIOS, including disabling all the onboard things (audio, 1394, etc). I've even tried waiting a few minutes with it turned on... but no post at all. HD light doesn't even come on.
The only thing I can think of now, is that the new graphics card is defective, or somehow the mobo fried something on the graphics card on the first boot, but I highly doubt that.
