Psu is most likely the cuprative. Are you able to test the rest of the rig with a spare psu?

Sword, try disconnecting all of the components from the board (except the PSU, one stick of memory and the processor) and see if it POST's. Have you also tried different cables with the hard drive (sata or pata)? Try also clearing the CMOS on the board and see if that clears up any errors. I would also try another CMOS battery. If the voltage dips below 3 volts then you might run into problems.
Let us know
Good luck

I tried slapping everything onto a different mobo I had that's compatible, but now the system won't even post. Fans turn on HD sounds like it's spinning and everything, sounds like a normal boot up, but I don't get any signal to the monitor. Any ideas? I'm concerned it may be the PSU that's shot...but I don't wanna go and tell him it's one thing then find out that's not really the problem. Thanks in Advance. |

I unfortunately don't have another psu to test the system with...the only one I have available doesn't have a PCI-E power plug for the video card or it'd work.

I tried clearing the CMOS earlier and I know the battery is good, the board was running a few days ago, also tried different cables for everything I could. I'll see if I can get it to post with minimal components...will have to leave video card too since the board doesn't have integrated video.
Quick Question...if it is the PSU, could that have caused the HD to not be recognized on the other motherboard but still post?

Sword44, this isn't always the case. If the battery is below it's specified voltage (3 volts) then you might run into problems. I'd advice testing with another CMOS battery (CR2032) or at least test your current battery with a multimeter.
Good luck

Checked the battery, it's still good.

Great suggestions Ike!

Sword, did you verify with the him to make sure he did not go into the BIOS and make any changes? Also make sure the controller on the board wasn't disabled. You could also clear the CMOS and manually reset everything to see if that resolves the problem.

Sword44, do you have another power supply that you could test with? If you have a multimeter handy you could also test the voltages to make sure they are within spec. Here is a great guide that explains this process: http://www.clunk.org.uk/forums/guide...ing-guide.html. It's better safe then sorry. The PSU may actually be fine but if you suspect it to be the culprit then it wouldn't hurt to look into it.
Do you have a lower end video card that you could use for testing purposes? It's possible that the SATA controller may be failing as well. Have you tried using completely different SATA cables? Just to clarify are we talking about an IDE drive or a SATA drive?
Good luck

That's about the last thing I can think of that might cause the problem. Edit: I also checked the battery and cleared the CMOS. |
