Hi guys,
Zalman CNPS9700-NT nVidia Tritium CPU Cooler (
Asus P5E Intel X38 (Socket 775) PCI-Express DDR2 Motherboard
Thermaltake VA9003BWS Kandalf Full Tower - Black
BFG GeForce 8800 GTS OC 512MB GDDR3
Intel Core 2 Quad Pro Q6600 "Energy Efficient SLACR 95W Edition" 2.40GHz

Heya guys,

Just took delivery of the above :) great, but unfortunatly it aint booting up. using a 620w Cosair PSU. I have CPU in (cpu fan plugged in,not placed on cpu yet though) 1 Gig of 8500 DDR2 RAM in slot 1. GFX card installed, sound card and then obvious power buttons etc.2 hard drives (sata2)

Now I plug in using the 8pin and the other power module (cant think of name) flick switch on PSU and the lights on Sound Card and MoBo light up, but nothing else. No boot up of the CPU fan, the PSU fan, gfx card fan. There is also no beep to indicate anything, like BIOS fail or anything.

I just cant think of anything else off top of my head. Any ideas of where I can go from here. I hope one of these aint DOA as Ive been waiting 2 months with no PC for this day :(

Thanks in Advance

So let me understand,please correct me if any of this is incorrect :D...

You've built a system and haven't installed the heatsink/fan assembly onto the CPU yet but you've plugged the fan into the header on the motherboard.You've plugged the power connectors from the PSU into the motherboard.You then switched on the PSU (from the back I'm assuming,where the power lead goes into the PSU) and the lights on the motherboard light up but no fans spin.No beeps,or display.All that fairly correct?

Ok,my first question is have you plugged the power lead into the graphics card? And secondly..and please forgive me if this is wrong..it sounds like you haven't tried pushing the power button on the front of the tower? If you have and nothing is happening,I'd be inclined to check the cable from the power switch to the motherboard..try turning it through 180 degrees.

Also,I don't quite understand why you wouldn't install the heatsink/fan assembly? If the pc does eventually boot,the cpu will over-heat fairly quickly and you risk damaging it.Install that sucker :D

Anyway,sorry if I've misconstrued your post..hope you get it sorted soon.
 
Hey,thanks for the reply,sorry for maybe some confusion but posting from an xda is hard :p

Your right in everything except for I have tried using the case switch to turn it on. I also haven't placed cpu fan on top of cpu,but for testing purposes I shouldn't have too right?
I've tested this from psu + CPU only installed to psu + cpu + ram to psu + cpu + ram + gfx card + cpu fan plugged in.

I have also by passed case switch, by takin paper clip puttin it in to green pin&black pin of psu and the psu has a low lvl noise from it but no fan start on psu (starting to think its psu)

ExRayTed: not sure what u mean by turning power switch round 180, u mean the connecter to the mobo round 180 (oppisite pins)
Any help once again would b great
 
First thing is to just short the connectors on the motherboard that you plug the front on/off switch into, just use a flat bladed screw driver across them and see if anything happens. If nothing happens, check the mobo light is on etc. Then come back and post if it still isn't working.

I would put the heatsink on the chip though to be honest. The heat spreader aint great at dissipating heat!
 
Hey guys,

Got a lend of a laptop for the day, I appreciate all the help thanks.
Ive bought another PSU for testing purposes as it stands.

Ive tried your suggestion Munkeh of shorting the on/off.The light for Mobo is still on but nothing happens that I can see or hear. Im right in saying I just need to put this across the Power SW connectors or all the connectors on the panel, i.e. the HDD LED, Reset, Speakers etc.

Am I right in saying that before posting etc I should be getting the beeps for CPU, GFX etc not detected right. I should be able to turn this thing on with nothing but Motherboard, 1 stick of RAM and PSU right just to get the beeps and go from there.


UPDATE: New PSU, have plugged this in and PSU Fan spins when I press the on button, still no beeps though! Going to install new PSU properly then the CPU Heatsink fan and then go from there. Im still concerned no beeps but step in right direction at least :)

Yep just across the Power SW jumpers. Put 1 stick of RAM, Graphics Card (with PCI-E power plug) and CPU all connected and see if it boots. Sounds like you might have a duff Motherboard or PSU. Try the new PSU and see if that works, if it doesn't then its your mobo and vice-versa.

Trying that now. Is tick of 8500MHz RAM, GPU,CPU + heatsink/fan. Plus new PSU which by loops of it is better seeing as the fan in it is at least spinning

Ace, now just remember no heatsink = baaad... mmm k?

K Mr Munkehhhh! I have that already done and now just loading peripheral one by one. Just on a side not a HD IDE cable is same as DVD Drive IDE isn't it?
Just only IDE Cables I have is a floppy and HD and I have an IDE DVD Drive. sata2 HD's
 
Well IIRC a FDD doesn't use an IDE cable but a similar style cable. And yes if I get what your asking you can use any IDE cable for and IDE drive.
 
Floppy drive goes on a floppy cable. These LOOK similar to an IDE ribbon cable. You can use the same IDE ribbon cable for HDs and for DVD drives BUT DON'T. Both devices will slow down to the slowest component, in this case the DVD drive. Put them on seperate ribbon cables to prevent this.

Hope this help. What actually fixed your computer in the end?

P.S. As stated - don't ever run a modern computer without a heatsink + fan on the CPU. It doesn't take long to kill them.
 
By looks of it was the PSU.
Basically bout 2 months ago my Mobo,PSU,GFX card all got fried (power surge) so I went out and bought a new PSU, thinking at the time PSU was only thing broke,how wrong was I. So now tried to build new PC (the one above) with the PSU that I had bought to replace the fried one, but looks like it was just the newish PSU that was broken, bought ANOTHER 3rd one today and seems to have fixed problem.

Only thing now is new build is not detecting my SATA drives and at this stage not only ****** off, but bit worried that the 2 HDs got fried in the orginal power surge, if thats the case Im gona gonna find a corver and cry in it :p
 
Ok guys!

Let me 1st say its all working :) after BIOS update. Dont ask me why / how / who but its working.Hurrrrah.
Now to everyone who contributed to this. Thank you, Im sure trying to understand my post originally was a bit of a pain (dam xda) but you helped anyway. Im gona leave system run for a cpl of weeks as is before I look into over clocking this baby but so far so good playing everything like a treat and multi tasking is now a dream come true.
Once again thanks for all your help lads.

Did you know that unless you change an option in the ms config it doesn't boot up using the 4 cores. having said that i noticed no difference as its limited to the speed of your hard drive anyway.

O and go cry in the corner anyway! it gives me some sadistic pleasure :p
