Is Motherboard Dead?

[PhatnaX]

Hello first time post.
I have been building another pc.

Amd am2 5000 cpu
Gigabyte GA-M57SLI-S4
2 gig corsair ddr2 800
750w AlphaPower psu
nvidia 6800
320 gig sata hdd
antec soho case

The problem is that when i turn the system on everything powers up. cpu fan,case fans, hdd, gfx fan and roms but i get no picture or beeps to say what the problem is. i have booted without the gfx and memory in but still no beeps. the monitor works as i still have my old system running on it. everything is new. I have built loads of systems before but never had this. just wondering if the mobo is dead?

A few things to check:
1) That PS seems like an el cheapo quality-wise.
2) Did you connect all 3 power cables to the MB (main 24-pin, square 4-pin CPU, and elongated 4-pin Molex near other corner of CPU)?
3) The MB doesn't seem to have a built-in speaker, so you won't hear any beeps unless you connect a case speaker (or other speaker) to the 2 speaker pins on the appropriate MB header.

Hello thanks for the reply.
Have used these psu's before.
the molex at the bottom of the cpu is for the pci express ports when you have sli. tryed it with it in but still no luck.
i have the case speaker wired up and its still not beeping.

Just because you have used the brand before doesn't make it a decent PS -- it could be defective. Otherwise, it certainly could be a defective MB. Good luck!

Even if it was a crap psu it should still be enough power to get the mobo to beep to fing out problems if it powering the fans through the mobo.

A defective PS (as opposed to low-quality, which is what I assume you mean by crap) could certainly have enough working circuits to power fans but not to boot the MB. Easy enough to check - just try a different PS.

It was the mobo that was dead. got it replaced. setup working fine now.

If you are having trouble with current Gigabyte boards, I recommend going to tweaktown.com where they have a Gigabyte forum to provide free technical support for their motherboards, graphics cards and other products!

I had memory timing issues on my P35-DS3L that I could not resolve and posted on their board and got a response within 2 hours - on the 4th of July. There are several moderators - if you get lsdmeasap, tell him hello for me. He was a lifesaver for me. Helped me tweak memory timings to make my memory work properly.

Something similar happened to me. Turned out, some pins on the CPU were bent. Turned a decent CPU into a brick.

I had me figures crossed the mobo hadn't fecked the cpu and everything up but they are ok. thanks for the link rockyjohn.
