Problem with 1st build - Answered

[mgo]

People (especially MechBgon) have been helping me. Have had 2 problems so far: 1) questionable power supply and faulty hard drive.

Well I changed out PS and now nothing works! I push the front power button and green LED light on my Abit NF7-S MB goes on and kind of blinks. End of story, no fans, no floppy drive, no video - nothings working that worked prior to the power supply switch out. Not even the front power switch which will switch it on but not off now.

I swear I just changed out the unit and made the connections. Power supply is an Antec Neo Power 480.

Any suggestions besides stick with my day job?

You'd mentioned in PM that you reset the CMOS, which will bring back the board's auto-shutdown behavior if it doesn't find an RPM signal on the CPU Fan header. If you plug an RPM-sending fan onto that header temporarily, you should be able to bypass that as you did previously.

If it still won't work, then take the motherboard off the motherboard tray, lay it on cardboard, and benchtest it outside the case with no case wiring except the power-button switch, and no components except the essential ones needed for POST: one memory module, the video card, the CPU & heatsink, and the power supply. What you described could've also been a short-circuit condition and the best way to eliminate them as a variable is to get the motherboard out of the case and off the mobo tray. So try that if needed.

Hang in there, just think how your knowledge has grown already (and the darn thing isn't even running yet!)

Were you grounded while making these changes?
I know of many people who have ruined cpu , mb etc. due to static electricity and they were not grounding themselves.

I would seriously try this one.. This has helped me out lots of times in determining possible shorts in the case etc. I would strip everything except basics(take out soundcard,controller cards etc) And use the cardboard method and see if you get any post. I would also check your cpu heatsink. Make sure it is making connection to thermal pad coorectly or if using thermal grease check to see if it has been applied correctly
