Z68X-UD3-B3 Quirks

Hello, I recently upgraded my CPU and MB from an Intel Pentium D with an
Intel D945PSN board to a Gigabyte Z68X-UD3-B3 with a Sandy Bridge. I
kept almost all my previous hardware the same.
After I installed and reconnected everything, my system wouldn't boot.
It would switch on for a fraction of a second to a few seconds and then
shut off. Troubleshooting narrowed it down to my PCI video capture card.
(Removed it, it booted up fine.) I contacted Gigabyte tech support about
it. It turned out my old card was PCI 2.2 compliant, not 2.3.
But now even with it removed, it's been acting a little weirdly when I
go to power it on. It was fine for about a week. The only thing I did
recently was replace an old IDE DVD drive with a SATA. Now it seems like
a crap-shoot if it will power on successfully. I'll switch it on, it'll
be on for a fraction of a second and shut off. Then I have to turn the
power supply off, let the caps drain, turn it back on, and repeat until
it works. I'm a little lost with what's going on.

Hardwa
Intel i7-2600k
Gigabyte Z68X-UD3-B3
4GB Corsair 1333 Dual-Channel RAM
450W Kingwin Power supply
3 Western Digital SATA 2.0 drives
2 DVD burners

TIA,
Brian

I might maybe look at if your Powersupply is putting out enough juice.
450W (and if it's an older PSU will put out less) sounds a little too
low for a new hardware setup and 3 HDD & 2 DVD.

450w power supply is really, really small.
Can you borrow a bigger one to test, like a 750w ?

It was in fact my inadequate power supply. I got a 750W and it boots
fine. Thank you.
