Just built computer problems

[mbesto]

I am trying to put my buddy's newly bought bag of parts together for a new box. I am a beginner at putting computers together but know how to do it none-the-less. He has the following specs:

MSI K8N Neo4-F Socket 939 NVIDIA nForce4 ATX AMD Motherboard
eVGA 256-P2-N553-AX Geforce 7600GT 256MB GDDR3 PCI Express x16
AMD Athlon 64 3200+ Venice 1GHz HT Socket 939

I have tried booting up with only these 3 things on an old 300-watt power supply i had laying around and cant get the BIOS to bootup, but the fans and everthing work. (basically when i hit the power switch everything sounds like it is working but nothing shows up on the screen) Does something of this nature need a 350-watt or 400-watt power supply?

help!!

Something is not connected properly or you forgot to connect something else.

Uhh...is the monitor plugged in?? LoL, never know, it has happened before.

Possible Suggestions, but this could be a number of things, to vague to pinpoint it:
-Try the other DVI port on the video card.
-Are both the 24 pin and 4 pin connections on the mobo connected to the psu? Are there any other connections that need to be plugged in, check the manual, DFI has two others.
-Where the hell is your RAM?

1. It's possible the PSU isn't good enough. On my mobo, there are like 4 power plugs I need to plug to provide sufficient power to it. I'm guessing the old 300 watt PSU doesn't have it all or maybe it has only a 20-pin connector when the mobo needs the 24 pin one.

2. Reseat the video card.....tkae it out and plug it back in.

3. Try another monitor.

Try one stick of RAM instead of two, and try different slots as well until you get a post. You can add the other one in later after making the settings.

Also, it could possibly be the PSU, but I doubt it since you're not doing anything intensive, but to have those parts running in the long run, you'd want at least a 450W.

Any empty power plugs on the motherboard?

Hi, Strip it down to bare essentials MB, PSU, Video and one stick of mem. If it tries to boot then add a KeyBoard and see if you get into the BIOS Setup. If so, then start adding stuff one at a time util you have a failure. That's the bad guy. 300 watts should be enough to test with. Jim
