I've been running my system nice and smooth for a while now. Upgraded a few parts last night and now I'm having a boot up issue.
Previous system:
Abit IC7-max3, Zalman 300w, 1gb Kingston HyperX, Nvidia ti9600, NEC 3500a, Seagate 7200.7 160gb and 200gb
Upgrades:
Seasonic S12 330w, ATI 9600, added SATA Seagate 7200.8 250gb.
The computer runs OK, but never boots the first time I try. Everything spins up in the computer, but I get no beep, no BIOS screen, etc. If I hold the power button 10 seconds, it turns off, but generally, when I try again and again using that method, I get the same results. However, if I flip the power switch on the PSU to OFF, flip it back on and try again, it usually boots OK.
Any clue what this might be? How can I troubleshoot this?

those external devices won't be drawing as much power as the hard drives spinning up, but unplugging them might give enough headroom to get the computer up and running.
a higher-wattage psu may fix the problem if that's what it ends up being, the best way to find out would be to monitor your voltage levels with a multimeter. it might turn out that it's just the individual unit acting up, another 330w s12 may power the computer fine.
