Hello Guys,

Thank you for helping me to gather my pieces together all along.

I hooked up my system today, but need more trouble shooting support.

When turned on the system for the first time, I get a message that there is no signal coming from the PC and that I need to click on the mouse or the keyboard to wake it up. That I did, and yet, still no connection between the monitor and the PC.

Could there be no connection between the motherboard and the graphic card?

On hooking up the GTX 260 graphic card, aside from the two 6 pins power cables, what else should I have to hook it up with?

What could I be over looked?

TIA
 
Yes, I did first tried the other with a VGA adapter to a CRT monitor, that didn't work either.

Then unplugged that and connected the DVI cable to the other DVI connector, still didn't work: no signal.

With these GPA cards, the menu doesn't show any other connection aside from the power cords, could there be other connections I over looked?

Thanks again.
 
You could try reseating the graphics card. Also what motherboard and PSU you got there?

edit: do the fans start spinning when you power on? double check the wiring, 24 pin and 8 pin connector to the mobo and 2x 6pins to the gfx card etc.
 
Look for 8 pin motherboard power connector from the PSU, it goes to the motherboard near the CPU socket. (make sure its the right 8pin, don't mix it with the 8 pin PCI-E connectors!)

Take the graphics card out and put it back in. make sure it goes all the way into the slot. You can try putting the graphics card to another pci-e slot to see if it works then.
 
The only 8 pins connector found on the mother is one indicated for "Download Flash BIOS Connector", and I am not sure if its the same one you are referring to.

If you don't mind, please download the manual for my MoBo here:

In the mean time, I will try as you suggested: moving GPA card to different PCI slot.
 
Thanks, guys,

You are right. That is an 8 pin connector. I tried the only 8pins power cable from PSU, but that would kill the system. What I mean is that when having that 8 pins plugged in, power up the system, will do so for a few seconds, then system shuts itsefl off.

Then unplugged that 8pins cable again, turned on system, and system stays on with no problem.

I searched through the menu and, unless I overlooked some where, there is no indication for that 8pins connector. Do know what's going on here.

Also, moved GPA card to another PCIe and still the same problem: no signal coming from your PC.

Unfortunately, I don't have another desk top to test this GPA out. Just moved into the area and don't know anyone with a system that supports PCIe, either.

Any other thought?
 
Your PSU should have a 4+4 pin motherboard connector. You need to put it in the 8pin connector found on the motherboard or your pc will not work.

By this, do you mean, some extra 4pins connectors that came along with the PSU, such I can plug to power suply cables directly connected with the PSU, so that I can then plug into this 8pins connector? I looked an didn't find any. Additionally, aside from that 8pins power cable that I mentioned above, there is no other power supply cable that would fit that 8pins onboard connector.

At the ends of the IDE power leads, there are two 4pins connectors, which are indicated as FDD-type power connectors, and the holes of such connectors look too small to fit the pins from the 8pins onboard connectors shown in the picture indicated above.

Please tell me more about this 4+4 pin motherboard connector. Should these be directly tied to the PSU box?

it looks about like this http://www.techpowerup.com/reviews/CoolerMaster/UCP_900W/images/12v.jpg

Afaik the 4+4 pin ATX power connector should be built in. When you put the two parts together it forms a 8 pin connector that you simply plug in the motherboard.

Thanks for the pic.

"Built in" as part of the PSU cables? If so, this PSU doesn't have it.

Interestingly, wondering why this Mobo and PSU would work for AnandTech's buying guide system, but not mine.

I am using the same MoBo, PSU, Process, and CPU fan.
 
Take the PSU on the table if you have to but the 4+4pin ATX cable is somewhere withing the cable mess.

I'm 100% sure of that. :)
 
Taken PSU to table. Looked through it all and the PSU packaging material. The only two things that are closest to what you showed me are:
1. X1 EPS/ATX12V 8-4 Pin
2. PCIe Power

Sorry for the blurry pictures. That was the best I can do under the circumstance.

Anyway, having seen that, what do you think? Apparently, this PSU doesn't have the exact connector you are referring to.

there it is. plug that in the 8pin connector found on the mobo.

edit: that connector is essential and not optional. your pc will not work without it.

:eek:That is the exact one that (power down/shuts off) the system when plugged in. :confused:

So, could that be said that these two (MoBo and PSU) are not compatible? Or what else am I missing that would cause this system to shut itself off when that essential power cable is plugged? :confused:
 
They should be compatible. If I were you, I would pretty much take the system apart and rebuild it with time and thought.

Connect only essentials (cpu&cooler, mobo, 1 ram stick, monitor, graphics card, psu) at first and see if the system posts right.

Here is a little list of very important little things that you probably did already but I'm just making sure....

Did you put thermal paste between the CPU and the cooler?
Did you use spacers between the case and mobo?
Have you tried with only one ram stick installed?
Have you tried using different PCI-E 6pin connectors for the graphics card?
 
Thanks, Mate. Your thoughts, recommendations, and reflections are much appreciated.:cool:

Make sense. Will give that a shot and keep your fingers cross.

Did you put thermal paste between the CPU and the cooler? - Yes/Checked
Did you use spacers between the case and mobo? -- if you mean those golden pegs/Stand-offs, yes.
Have you tried with only one ram stick installed? -- No, have all three in now. Just curious, why would this make a difference? Isn't the more the better?
Have you tried using different PCI-E 6pin connectors for the graphics card? Yes, made no difference, granted, the 8pin power supply was off.

Incidentally, what does +P Led and -P led mean? They are not standing for "power" are they? My case comes with a front panel that has two of those leads and I could not find a place on the MoBo to plug them in. Could that be another (small but maybe) culprit?

My case is a HAF932.
 
taking most of the sticks off is for troubleshooting purposes.

+P Led means its the pin you connect your cases power led + wire.
-P Led = - Pled wire

edit: look for your motherboard manual to find out which wire goes where.

the most important thing is you connect power swich to right spot
 
OK,

Replugged every thing, including the 8 pins power connector and 2XFDD power connectors, turned the system on, the led lights on the mother board came on but nothing else, not even the fans as did yesterday.

Only plugged in 1 memory stick.

Difference, this time the PSU has humming noise like some thing is trying to work or turn but can't. Could it be that it's the PSU that's causing all of this mess?

Update: By passed the MoBo, plugged one of the fans directly to a power supply cable, turned on system, fan is not running.

Could this confirm that it is the PSU that's causing all of this?
 
look for the motherboard manual and see which slots are preferred for the 3 sticks. And plug them all in.

Did you plug in 24pin mobo connnector, 8pin mobo connector, 2x6pin PCI-E connectors?

also, do you have another graphics card around that you could try?

also, do you have another graphics card around that you could try? -- Unfortunately, no, don't have one. WIsh though that I do.

Not sure if you saw the update in my previous post, if not, please look at it.

Thanks again.
 
No you need the motherboard to turn the PSU on. Plugging fans to the psu and not connecting psu to the mobo doesn't confirm anything.


Take everything out of the case. Assemble the PC on wooden surface or similar non conductive.

Double check all psu connection and make sure every psu cables are plugged all the way to the connectors in the mobo&graphics card.

Parts u need:

PSU
CPU&cooler
Motherboard
3 sticks of ram
graphics card
monitor
keyboard
mouse

power cables to connect:

ATX12V 8-4
24pin
2x6pins PCI-E
+fans of course

Use the motherboard manual as guide to assemble, skip the cpu&cooler installation part as you have done that already.

Use the motehrboards built in power on button to start the pc.
 
The extra 'cable' is SLi connector for using two nVIDIA graphics card in SLi.

Yes fans should start spinning when you turn on the system.

What is that cable going to the mobo next to the top PCI-E Slot?

Try moving the GFX card to the top slot.

Does the mobo standby power led light up?
 
What is that cable going to the mobo next to the top PCI-E Slot?: -- That's just to ensure that the MoBo gets extra power supply for the FDD power cable.

Try moving the GFX card to the top slot. -- Tried that too. No luck.

Does the mobo standby power led light up? -- Yep, it does.

What could this be? If the PSU, could this be more than just the PSU?
 
It can be mobo or CPU too. Try taking off that extra cable. And try one ram stick at a time with two sticks to see if they are good.

If the fans still don't start spinning, and you are too afraid to do teh PSU test, i would say RMA it. But it can be the mobo too!

If u could do that PSU test, it might save you a lot time and RMA ;)

edit: oh and reset motherboards CMOS. Instructiosn found in the mobo manual.
 
I'm not sure it's been mentioned but there are quite a few mobos where the preferred RAM slots are the one further away from the CPU. In your case, the green ones. Worth a try...
 
FDD power cables off, 1 and 2 rams attempts, no PSU fan come on, still no signal to monitor.

Looking for some wires to test PSU,

Just a quick one, this PSU test requires it to be plugged into outlet correct? The instruction didn't say any about whether to or not. Have you tried this personally?

I haven't tried it personally. PSU needs to be plugged to outlet.

Actually, the MoBo's manual specify that with the 1, 2 and three modules, start out DIMM 1 and then DIMM 3. Only the 4 modules, should start at DIMM2.

Thanks for the thought though.

Tried that too, and still not working.

Haven't chat online for a long time. So don't have any of those. I could install though for this purpose. Any preference?
