I've recently built 40 identical computers, consisting of

Intel E8200
Gigabyte motherboard
9800 GTX
Corsair dominator memory (2GB)

Whilst most of them are running fine, 5 of them are getting problems, which i hope some of you might be able to shed light on. They all boot, but there is no display, and NO post beep. I have fixed two by reseating the CPU (no idea why) but 3 of them continue to do it. Any ideas?
 
now that is very strange that you have used identical stuff and only getting problems in some.

first thing i would check is ram voltage, i have corsair ram and if i leave my ram voltage at what the mobo defaults to. i get no display on my screen aat all litteraly nothing. if i enter bios and up the voltage to what corsair recommend it all runs perfectly :)
 
No display at all to see bios screen. Everything sounds like its starting fine (fans spinning etc) but no display, and no beep.
 
that is exactlty what happens to mine when ram volatage is not set.

allthough i guess it could be something else.

try reseasting the gfx and ram. or try starting with only 1 stick of ram installed not 2 sticks.
 
seems really strange. Maybe start swapping some components like the graphics cards into working machines and see what happens.... thats what i do to find faulty components.

Click to expand...

Are motherboard defaults 1.8v?
 
Out of 40 systems I would have thought it quite possible to have one defective CPU, one bad motherboard, one bad stick of memory.

As an earlier post said, try swapping some parts, you have plenty of source material!
 
Right this is REALLY odd. 1 machine we couldn't get working. Other 3 we fixed, just re seated the cpus, but when we put them back in their bays they got the same problem again! as if moving them has disrupted something. Surely these S775 can't move?
 
now that really is odd and nope they cant move not unless the cpu cooler is fiitted really lose but then i would have thought it would requir e knock to dislodge.

you say they fit in bays do the cables at back get pushed when you slot tyhem in ? could it be alooose cable at back ie monitor cable.

when its in its bay is it using any diff leads to when you test it ? maybe faulty lead.
 
Not the cables. The only thing i can think of is possible faulty RAM slots. Tried different RAM and graphics in all machines, same thing happens.
