PC wont boot.......??????/

Put 1 stick of RAM in the 3rd slot away from the CPU.

Before you do this, turn off the PSU switch at the back and remove your BIOS battery for ten minutes.

Use these 10 mins to treat yourself to a nice brew :D

Put battery back in.

Power it up.

If this works, enter BIOS and set your RAM to correct speeds, timings and voltage.
 
Are you sure that all the mobo power connectors are all in correctly? Refer to your manual to check this. You should have a 24 pin and (I believe) and 8 pin connector on your motherboard.
 
Still stuck people, any ideas??????

Iv'e got another older PC and i'm gonna check all the parts i can with that, only things i cant check are MB and CPU, any tips would be great,

Cheers
 
If you can try an 'older' cpu in your board, it would help...may have some issues with the board detecting the cpu...Or the ram may be causing issues.

Try what you can in the other system to see if they boot the system up.

Do you have other ram to try in your new system? And a different cpu? Would be worth giving them a go if you can.

At the moment your system isn't posting, so it's either your motherboard not detecting your cpu, or your board not detecting the ram properly so it can't display any video. Or your graphics card isn't detecting perhaps....Any older G-cards laying about?

The problem is you don't have a case speaker, so you can't determin if the system is even trying to post or not....
 
Your problem sounds similar one I had. You have the same RAM as me except I have 2x1Gig. Apparently this RAM is sensitive to voltage settings, my mobo defaulted it to 1.8v when it needs to be set at 2.0v. Until I changed the voltage settings, the computer failed to start up if it had been off for a while, once it had (literally) warmed up it booted up fine.

Your mobo is different to mine, but I suspect that it too is defaulting the RAM to 1.8v or some other voltage that it doesn't like. Either that or the RAM itself is bust. I would suggest swapping out the RAM totally if you can and haven't already. Otherwise you could try what I had to do and turn on the PC and let it sit there for a minute or so on its blank screen to let it warm up. Restart it, if it posts then go into the BIOS and change the voltage for the RAM. For me it had to be 2.0v, but to be sure I would check this thread for the correct settings for your exact RAM and motherboard: http://www.ocztechnologyforum.com/forum/showthread.php?t=27196 (NB the info for your RAM is about halfway down)

I have tried all the RAM in my older system and it all booted up 1st time, tried clearing the CMOS and rebooting no good (ASUS Support):(
Does a Pentium D fit in the new MB?
Does the Q6600 Quad fit in a ASUS P5LP-LE?

Have already tried warming the system up but it justs sits there with all the fans whirring and no display?

Have tried the RAM in other PC and all works perfect inc 3gb of other RAM i had before i upgraded:(
 
No, I'd say it's very risky taking off the cooler, you could bust your CPU doing that and I don't see how taking off the cooler would help anyway.

Have you tried some other RAM in your newer system yet? If that works then maybe you could set the correct voltage with that RAM in then swap in the new RAM. Of course this could very easily bust the older RAM if it doesn't like that voltage, so try that with caution.
 
Don't take the cooler off no...the most I would do is "rest" the cooler on top of the heatsink, so it's still atleast got contact with it.

Try that actually, had some boards at work that stopped working due to the pressure of the cooler mechanism bending the board too much.

It could be a faulty motherboard you have in all honesty, atleast you know that all of your ram works.

If the Pentium D is Socket 775, then yes it would fit, if it has pins on the under side of the cpu, then no it won't...

Delvis,

Have just finished putting the original MB back in with everything back as was, and it booted straight up, so it must be the MB musn't it?
 
So everything works from the new system in the old motherboard? If so, I'd say yeah it is.

As long as you had all the power connections plugged in, ie the 24 pin ATX, 4/8 pin cable, and the cable to the graphics card...Then I'd say yeah it's the board in some way. You tried removing the CMOS battery didn't you?
 
Yep tried that and just about everything else, i reckon it is the MB, whether it was faulty when i got it or i damaged it, i dont know, i dont see how i could have but you never know.
Spoke to Support and i'm sending it back for testing,

Cheers for all your help and advice,

Much appreciated,:)

PS. Will probably be back on again soon when i get another board, until then, adios.
 
Update: Just got an email from support and it turns out the board was faulty and there is already a replacement winging its way back to me:):):):)

I also want to take this opportunity to thank OCuk for theur excellent service and support they provide.

Cheers Guys
