New build won't boot.

Samueltastic · 8 Mar 2012 at 22:02

Hey guys my brothers friend has asked me to look at his new build as it won't boot.
the fans start up for 5 seconds odd then it turns off and on in a loop again.

I have tried;

Removed GPU
Only the 4pin and other main mb cable in
Clear cmos (removed batt)
tried a different PSU.

Anyone else got any ideas before I head for more extreme measures?

Thanks.

Try one stick of ram in all the slots, repeat for the other stick/s

Perhaps ensure that the ram modules are pushed in fully - when I built my first pc not long ago, I thought I had pressed the ram in fully, and since im posting this you can guess I was an idiot and hadnt, only 1 side fully clicked in, worth a shot.

Take everything out and start off fresh - one thing at a time, checking and rechecking.

Like danjama said, start again and double check everything

Although sounds like RAM or maybe bent CPU pins...

Right managed to get round to this finally.

Tried one stick of ram and success I get it to try to boot ( No OS atm)

Both sticks = nothing

tried the other stick of ram on its own. It boots.

Tried 2 sticks of ram from my computer = nothing 1 stick and it boots

Tried the ram from his computer in mine. Boots no issues.

Only thing I can think of is there's something wrong with the ram module on the motherboard as I can't think of anything else?

Try going into the BIOS, setting the RAM timings/frequency etc to what is written on the sticks, save and exit, power off, try with both RAM sticks?

What board?
