Here are my specifications:
Antec Sonata II case w/ supplied SmartPower 2.0 450W ATX12V v2.01 power supply
ASRock 939Dual-SATA2 Motherboard (Connected to the case via 20pin plug. There's also another 4-pin plug (and one that's connected to the 20pin PSU plug), but when I connect those the computer won't start at all.)
AMD Athlon 64 3200+ Venice (Cooled with a Zalman 7000b-Cu w/ Arctic Silver thermal paste. HS/F is plugged into the mobo correctly and runs when I turn on the machine.)
1GB Rosewill RAM
XFX NVidia GeForce 6800GS (The default 6-pin plug wasn't supported by my PSU so I used the included converter to change it into two 4-pin-sized-but-only-3-pin standard molex plugs. Both are plugged in. It's connected to the monitor via supplied 15-pin D-SUB.)
CMV 15" Monitor (Powers on, plugged in with 15-pin D-SUB to the GPU as mentioned before.)
NEC DVD Burner (Plugged into the PSU via 4-pin standard molex plug, and plugged into the mobo via IDE ribbon (primary)).
Maxtor 200GB HDD (My PSU has a connector that fits into this thing's male, but the documentation that came with my case said to use a converter to convert it to a 4-pin standard molex, so I did that and plugged it in that way (not sure if that was necessary/good/bad). It's plugged into the motherboard via SATA cord.)
Thanks for any help! If you need information I'd of course be happy to supply it.
