NOPE!!!! same thing! and i even have a 700w psu. and a good 1 to boot! i got the raidmax BLACKSTONE. so i'm compleatly stumped . need u guys help badly.
It was a dumb idea to do the PSU to begin with. This wasn't a hardware change, it was an OS change.
Its always hard to troubleshoot like this without seeing the unit, but you can try.............
1) installing Windows 7 32 bit and see if that works. Might give vista 64 a whirl as well. Since it works with Vista 32, it should work with 7 32. And if it fails with 7 64 it may fail with Vista 64. In any case, will tell us more about the problem.
2) Barebones the system as much as you can. Remove the GPU since the board has on board video. Keep the number of ram chips and peripheral devices to a minimum. Its possible there is a problem with a peripheral device.
3) Reset the bios to default settings.
That is all that comes to mind for the moment. Let us know how this goes.
