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.
 
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!
 
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!
 
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
 
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

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?

Also, regardless of getting it to post, the symptoms are obvious. So, I have already removed the GPU to see if they go away (stuttering fans, flashing case fans and very weak power outage) and they do not.

On that basis, clearly the GPU is not at fault
 
im going to get up early and quite literally strip the pc down to its pants. Then reassemble in an exceptionally thorough way to make s=damn sure the case fans are not shorting anything etc.

If that does not work, then ill shell out some cash and get a replacement PSU but i point blank refuse to believe the power supply has popped its cloggs right at this very moment. Fair enough if im wrong.
 
Stulid, the thing is, the symptoms are pre post! Its stuggling to power up anything in the case such as light and fans etc. I have removed the GPU entirely and yet the symptoms persist! So, on that basis, even if i could use the onbaord graphics, it wont boot anyway.
 
Been up since 7am. Dismantled the entire machine. Then, externally from the case mounted my old system and connected it to the power supply. It worked like a dream. Then did the same with my new system (again, externally from the case to make sure it was not shorting anything) and, no post!

My feelings now are that the motherboard may be faulty as it really dies not appear to be the psu considering it still powers my old system perfectly.

Thoughts?
