ok guys,

just installed my 15 2500k system OCUK bundle but im getting NOTHING from my SATA hard drives.

The GPU spins up, the PSU spins up, the CPU fan spins up and everything else seems alright. However, the rear case and top case fans are reluctant to spin up on start up and that is leading me to think that its a power issue.

However, my PSU is a OCZ GameXStream 600W ATX2 power supply so should be more than enough to handle a 5850 + the hard drive and associated ram and 15 2500k.

Im at a loss and im tired. I have tried powering the hard drives without the GPU installed, one HD at a time and vice versa and........ nothing. ideas here are welcomed dearly.
 
The OCUk overclocked profile is saved in a user profile, so loading defaults in the BIOS is a start.
 
So what exactly do you recommend mate? Resetting the bios surely won't make a difference. The machine will not even post! There is no monitor response no nothing!
 
A clear CMOS can solve many problems.

After that I read about a little trick to try,

Remove the RAM, power On then OFF.

Place a stick of RAM in the slot furthest away from the socket, power ON, anything happening?

Move this stick of RAM closer to the cpu each time and test.
 
Ah ok thanks for the advice. I've. Never been in a situation where everything seems to work appart from the hard drives even when I know they are connected properly!
 
The trick behind the ram, is,

1) when the PC boots up it checks the connected hardware against a list of what it checked before, removing the RAM is a significant hardware change and forces it to do a complete re-check of whats connected. Then the moving the stick of RAM closer etc triggers at a certain point (signal length) that kicks it into life.


With a clear CMOS will I not loose the over clocking tha I paid ocuk to do for me?!?

A BIOS update will clear the user profiles, if your double worried,, right them all down, but I know the ocuk profile is saved in the BIOS, restoring defaults wont delete it.

Make sure the graphics card is seated firmly, sometimes new you have to push pretty hard to get a card properly seated in a new mobo.

Also try with out any drives connected and 1 stick of ram, bare basics just to see if you can get it to post at all.

And what bundle is it?
 
Just tried with the ram and the symptoms are strange. A stuttering start, case lights flicker and fans struggle to start. No post no hard drive activity nothing. Just a spinning CPU, gpu and psu fan
 
I would take it all out of the case and test with minimal componants just to get possibles down to an absolute minimum.

Doing this first before slapping everything into a case is good practise anyway tho, imo anyway :)
 
Have rebuilt the damn thing today- made totally sure no cables are shorting. Still...... Nothing. Power lights on the fans stutter, the fans themselves stutter, no post, no hard drive activity nothing. Just a feeble sounding power issue. Help guys, this power supply has not let me down for years.
5850 gpu
I52500k
4 gigs ram
600watt ocz gamestream psu
 
have posted in the after market support section but any more help hugely appreciated.

I have tried to see if i can cure the stuttering power, lights and fan issue by removing the GPU and seeing what happens when the power is turned on. Still the same symptoms - its looking like a proper dodgy power supply but SURELY if im using the same power supply that i have done for years and it has never let me down, this is just waaaaay too much of a coincidence?
