First thing I'd do is get a bigger PSU. My old 400W PSU that powers my XP
system withou a problem, crashes my A64 3000+ system within a minute of
posting. Sometimes I couldn't even get to bios, and was never able to save
it. It's likely that your 300W PSU doesn't supply enough voltage on the
+12v rail. Did you hook up the 4pin (P4) +12v connector, assuming your
board has one. Both your cpu and video card will draw more current than
my old GF3 card. So if I were you I'd buy a cheap $15 550W PSU and try
that first. You might try disconnecting all the drives and see if you can
get it to boot to bios. If it still won't that won't tell you much, but if
it does make post, then you can be pretty sure your PSU isn't big enough.

I bought 3 (long story) cheap PSU's and I tested all three with my system.

Had the same problem with my kv8-pro. Turns out the problem is simple:

From the way the motherboard is designed, even when the RAM is securley in
the slot bows in the middle, so the centre of the RAM stick isn't connected!
Try supporting the motherboard from underneath and push the RAM firmly down
in the centre so it goes into the RAM slot.

That might help!
