Hi all

Wasnt too sure where to post this, so...

I have recently bought a new P5N32-E Sli Plus board, Q6600, BFG9800 GTX+ and 2x2gb GeiL 800mhz ram.

Me bein me (comp disaster) made sure I knew where everythin connected, followed to book to the letter and finaly got everythin in the correct place.

However:

When I turn the comp on, I get nothing. No screen, no lights for my "front devices (reset, power HD)"

I have tried the ram seperatly, in diff slots even my older DDR2 ram, but no luck.

Any suggestions pls?

Cheers

Andy

First obvious thing is to make sure everything is connected and switched on, psu, psu cable to mobo, case power to mobo, etc.
 
K,

I just tried that then saw the reply ;-)

Everythin is def connected. I have power, the power cabe fully connected to all areas. I even just checked and I have the little "green light" shinin at me on the board itself. Even the led's on the ram are on. So I assume that power is actually gettin there?

Cheers
 
have you connected the power button cables from the case to the motherboard properly? i remember they were a bit tricky as the writing is so tiny on the mobo, try moving them to different slots if its not working as it is, it should be in your mobo manual where they go.
 
When you say you 'get nothing when turning the PC on', do you mean that the PSU switch is on and you press the button on the case only to be met with a deathly silence (i.e. hard drive doesn't spin up, fans don't spin up, no beeps etc)? If so, have you checked the power switch connection to the motherboard? If that's not what you mean then describe it a little more and I'll try to think what could be wrong :)

Also, it's always worth trying a CMOS reset, but this sounds more fundamental than that.
 
Hey,

K, double checked the connections, and everythin is in the right place. When I press "power" I get fans spinning, graphics card fans spinning, led's on motherboard. But no Hard drive, cd drive, power or reset leds on front of case! Even if I try and "power down" by using the button on the front of the case nothing happens.

I have tried a CMOS reset, I think!? But another friend recomended taking the battery out, leaving it for min, then replacing it and trying again. That didnt have any effect.

1 thing I did make sure of is I wore an anti-static wrist band that was attached to my case (as advised) but it couldnt be the CPU could it?

Oh, I also get "no beeps" nothing but the sound of fans. And bein and Antec 900 case, there is a few ;-)

Thanx for the help so far, appreciated.
 
OK, have you got a PC speaker connected to the motherboard? I don't suppose the Antec case comes with one, so I'm guessing not. If not, you may be missing beeps which would tell you of the problem. Have a look in your motherboard manual to see if it has any kind of index of beeps and what they mean, or if there is a speaker on the motherboard, or if there is an LED type alternative. Most motherboards have some kind of diagnostic system to enable you to troubleshoot these types of problems.

Also, try reseating your cards, RAM and CPU to make sure there are no problems there. Presumably you have the 24pin power connector and the auxillary power connector (4 or 8 pin) connected to the motherboard?

Just be aware that the LEDs on the front of your case could easily be wired in the wrong way and therefore won't light up - try flipping the cable around so the it connects to the opposite pins.
 
When all else fails there is nothing for it but to reduce to the minimum of components and after that remove the mobo and rest on an anti-static bag (the one it came in) and try and pwoer it up with just cpu, graphics card and one stick of ram.

Sometimes you can short a mobo out on the case.
 
Ok, after speakin with a friend and someone else lookin aver things, they both eem to think that the "Thermal compund" might not have been applied properly (my error) thus meltin the CPU. Oh joy of joys.

1 thing that isnt certian: If this is the case, will it have effected the mobo?
 
Hmm. You have to try really hard nowadays to kill cpus. I can't beleive that you applied the thermal paste that bad! They have thermal shutdown built it.

What reasons have they given for this? Have you had the cpu out and is there signs of thermal damage eg burn marks etc?

Best thing to make sure is to try it in another mobo or try a friends cpu in your mobo.

On the plus side if you have fried your cpu it is highly unlikely that your mobo is damaged.

What HSF are using, I personaly doubt you fried the CPU.

Have you tried removeing all the components and building it on a bench to rule any possible shorting ect

You have connected any power cables to your GPU and the extra 4 OR 8 Pin for the cpu power like Namistai mentioned, thought I double check ;)
 
Well I for 1 cant see any burn marks, and neither could they. But it was a "feesible" (I spose) explanation. What I dont get is: My old set up: A 2 year old dual core, was taken apart so many times, heatsink off, and never any other thermal applied and it never failed.

k: heres what I bought and tried to install:

Q6600
Asus P5N32-E
2x2gb Geil black dragon Ram
BFG 9800 GTX+

I already had the thermal paste stuff: Artic Silver 5 and a heatsink/fan: Arctic Cooling Freezer 7 Pro

Before I pressed the "confirm order" button I double checked that everythin was compatible.

If what I have been told is true, then a new CPU is on the cards, and a lesson very well learnt.
 
I would not rush into that yet. Try what i said earlier. Get everything out of the case. I have seen too many computers with the mobo shorted out on the case.

Set it all up externally with the minimum of components.

You really do need to do this before just getting a new cpu. The mobo may indeed be faulty, not the cpu.

Also find a speaker, as suggested, and see what, if any, are the mobo error codes.

Never make assumptions.
 
K, thank you all. 1st build and a little "jittery"

I presume that i will need the cpu, heatsink/fan as a bear minimum. i do have a speaker I can use (I think) if not would headphones do?

If my cpu has gone stuffy, am I right in thinking it wont screw mobo up?
 
You need to disconnect everything apart from the ram, cpu and gpu. Also read the motherboard manual and check all the jumpers on the motherboard, if the jumpers are set incorrectly it can stop the pc booting up, sometimes in the manual you find out that you need to make jumper adjustments for your particular setup or that certain ram configurations aren't supported. Also is your power supply big enough?
 
OK thanx. Gonna try that in a sec.

I recieved a "Q Connector" thing with the mobo, and put the relevant: Power switch, reset and HDD in the correct places.

My Power supply is a 650w, which I was told by numerous people that it was sufficient for a single 9800gtx+ and the rest of the set-up, but obvoiusly if I wanted to go sli I would need at least 800w.

On the ram side of things I tried my new Geil, but also my older corsair with the same results.
 
OK just tried a few things suddenly realised that a lead wasnt actually connected, as it wasnt 1 I had ever needed. Now however, I can get the "ATI Lifestyle" 1st screen up, press "del to enter setup" but then power dies out, nothing seems to be overheating tho?
 
What make is the power supply though? If it's a crap make it may not be able to provide enough current on the 12v rails.
 
24 pin plug connected to mobo? (must be from your post above)
4 pin 12 v connected to mobo?
6 pin to gfx card connected?
CPU fan connected to cpu fan header on mobo?
Keyboard connected?
I'm assuming the on off switch is connected to the correct to pins from your post above. Have you got the reset switch in the wrong ones?

Afaik headphones are worth testing in the green stereo jack but wont beep on all mobos? (not sure myself)

GFX card not fully seated is fairly common. Take it out and reseat. However the symptom you describe about seeing the post screen then turning off screams psu to me.
