Need help - PC won't post

[Fourteen]

Just started putting my rig together today (see sig - it's all brand new except for the case and optical drives). Everything was going along relatively smoothly. I had 2 Raptors hooked up in RAID 1 to the NV SATA controller, and was starting to hook up my 4 Seagate drives (one by one) to the SI SATA controller. I hooked up 1 Seagate drive, configured it in Windows, then rebooted, and now the machine won't POST at all. The 4 LED's in the lower left are all lit, there is power going to all HD and CD/DVD drives, as well as fans.

 

I've been reading the forum here, and saw many people having problems with the Ballistix ram, so I tried putting them in different slots, in different combinations, but nothing. Even tried using the Corsair PC3200 ram from my old rig, still nothing.

 

Not sure what else to try at this point, and would really appreciate some guidance.

 

Thanks in advance.

Try this:

 

Uplugg the PSU from the wall plug

 

push the "power on" button a few times

 

wait 5mins

 

plug in the PSU & push the "power on" button

 

Did it boot?

Ok - I'll try almost anything at this point. Let you know in 5 minutes

Hmmmm, if only I had a multimeter. Time to try a different PSU then.

 

Right now I've only got the video card, case fans (4, 80mm), and floppy drive connected to the PSU. I can't imagine that would draw too much power for the PSU to handle.

 

Another thing, if I power up with no ram installed, I do not get the error beep.

Try 1-stick of RAM at a time.

Yeah, I've tried that too.

Well, the stores were still open so I snagged an OCZ Powerstream 520, and still the same problem. All the lights on the PSU are green, indicating that the power on the rails is with spec.

i have a prob close to yours.

did this happen when you installed your 7800?

[MoFro]

i just got mine to work, try this move your 7800 to the bottom slot and try that i read something about ati cards not working in the top slot.

i hope this helped

Thanks, that didn't do it though. The PC had been working fine with the 7800 for 1-2 hours, then I rebooted and it won't come back up.

 

I've taken the entire thing out of the case, only video hooked up, and the 4 required power connections made, and nothing yet. I'll play around a little more, maybe try reseating the CPU and heatsink.
