New build problems

Ferax · 10 Jul 2008 at 12:28

Hi guys,

Hoping someone can help. Just finished a build with a P5Q Pro, q6600 and 4870 running off a corsair 650W psu. Plugged all in and powered on and got into the bios. Was justing starting to look through the bios options (hadnt changed anything) and it powered off for a few secs before coming back on. 5 secs later it went off again and nothing I can do will get it started again.

Everything looks to be connected ok, the green power LED on the MB is on, just is dead

Any advise would be very gratefully received as I am ont a happy camper right now...

What ram have you got?

I'll start things off with stating the obvious. First check all the connections, make sure they're all in securely and in the right place, especially the power connectors and the front pannel connectors.

Next, check the CPU cooler is on properly so that your CPU isnt overheating and switching off automatically.

If its not either of them, wait for someone with more ideas and advice than me.

PK!

4GB OCZ PC2-5400 C5 in there atm.

yep as Tetsu said what type of ram is it?
certainly the first thing i would look at is the Ram Voltage it is quite common for motherboard to run the Memory voltage at default ie 1.8-1.90V

u need to set ** Ram Voltage to 2.10V for that ram

Cheers, just tried taking the second stick of RAM out, but still wont power on even for a second. The closest I got was the fan on the psu twitching briefly! Was in the bios to adjust the ram voltages originally, but before I could get to them the power died.

I've just finished checking all the connections for about the tenth time, everything seems to be firmly seated, all power cables are connected, just wont even start to boot up.

Now thats just bizarre - was just sitting here trawling the net for ideas, and it booted up. Could this be a temp problem, with maybe the Tuniq tower not be seated properly?

At least I have been able to change the RAM voltage now - have to see how it goes form here on in.

Thanks very much for the swift help!

Let us know how it goes, even if it's a success. Sounds like a capacitor problem / power supply to me, but I'd be happy if it was the old "OCZ undervolt problem" again.

Good Luck.

In most BIOS systems there is a page where you can see the temperature of the CPU and other parts. This should give you and idea if this is the problem.
