Need Help, PC wont POST. No Beeps either!

[zerone555]

I really need to some help with the problem I am having with my rig. I had to take everything apart coz I was moving a couple of weeks ago and finally got the chance this weekend to put everything back. It was working great before.

So, when I tried booting-up after everything was installed, it didnt POST and I didnt even hear any beeps. I tried re-seating my GPU, RAM, CPU and tried booting with minimal set of components but nothing helped. Right now I have the mobo setup outside my case with only the RAM, GPU and 2 HDDs hooked-up with stock air-cooling, but it still wont post.

One thing I noticed after putting it outside my case is that the CPU fan would turn-off after running for a minute or two and the GPU fan keeps running at full speed (normally it would slow down after a few seconds).

I really have no clue at this point about what might be wrong. Any help or suggestions would be greatly appreciated.

Is this the only possibility? Just wanted to make sure before I order a new one.

Try a new PSU first. Replacing the motherboard does seem like a good option at this point - a friend of mine recently had a very similar problem and I had to replace the motherboard. But try a new PSU and report back

Do you have the secondary four pin ATX plug plugged in?, the one that plugs into the board by itself. I had a similar thing when building a new box, it wouldn't post at all since I had forgotten to plug it in.

I am pretty sure I have it plugged-in. Actually, this was first thing I checked . Since mine is a modular PSU, I am thinking a bad cable or the connector might be the problem.

I am gonna try a new PSU today evening once I get off from work and see if it works then.

I am having what i think is a PSU issue right now too, and mines modular I think I am going to try and get antec to replace it with a non-modular series (earthwatts/true power)

So I got new PSU to see if works then and saw the same problem when I tried booting the first time. But on the second boot, it started giving me long beeps continuously probably because the PSU didnt have enough juice. So I switched to my DA750 after that and it booted fine and I got windows successfully .

I am gonna put everything back in my case with my WC loop whenever I get a chance and see if everything works.
