My monitor won't detect PC No Signal

October 24, 2014 at 11:01:35
Specs: Windows 7
So I just made my new gaming PC and I built it and everything, but my monitor will just stay in hibernation mode/orange light and I can't get it to work together. Can you help??

Things I've tried:

Connecting VGA (monitor) to DVI (GPU)
Connect VGA (monitor) to VGA (Motherboard)
Remove GPU and Connect VGA (monitor) to VGA (monitor)

GPU: XFX 6790

Have you tried a different VGA cable? Also, are you using a DVI to VGA converter? If you are, make sure it's either active conversion or you are using a DVI-I port.

If this doesn't work, you'll either have to test the monitor on another computer or test the same computer with a different monitor. This will let you know if it's a hardware issue (motherboard probably), or (more likely) an issue with the monitor itself.

Apparently you didn't bench test before installing the hardware in the case?

Not using converter, using this: http://www.amazon.co.uk/Monitor-Pre...
Also using a standard VGA cable which came with my monitor I think about 3-4 years ago.
Specs:

Motherboard: Maximus Hero Vll
CPU: 4670k
RAM: Corsair Vengeance Pro
CPU Cooler: 212 Evo
PSU: Corsair CX750M
GPU Model (In reply to ko888): HD - 679X - ZH Part No: HD - 679X - ZHFC.
HDD: WD 1TB 64mb cache
SSD: 840 evo 250gb
Fans: Noctua Industrial NF-F12 3000RPM
Case: NZXT Phantom 530
Do you hear your system post? What do you mean? all the fans are working, HDD is vibrating too.

I connected my Laptop on which I'm writing to you guys to the monitor with a VGA cable. It works, just contrast is quite low (screen more yellowy white).

Monitor: G195HQV (acer)

Another thing I thought was worth noting, is that the monitor is 3-4 years old. I read somewhere that there is a old and a new vga port and the old one isn't compatible with the others?

As far as I know VGA is VGA and as long as the video adapter puts out a signal at a resolution the monitor can handle it will show on the monitor. Even an old monitor will show the posting or logo screen and be able to go into bios setup since that resolution is no more than 640 x 480. Very unlikely the problem is with the monitor.

Do you get any beeps when starting it up?

With the power cord disconnected, make sure the cpu and ram are compatible with the motherboard. Make sure the cpu heatsink and fan assembly are correctly and securely attached with a dab of heatsink paste on top of the cpu. Temporarily disconnet all the drives and remove any unnecessary cards (everything except video). Disconnect any USB devices.

Then plug it back in and see what happens.

Did you connect ALL power connectors to the MB? Especially the 12 volt connectors near the CPU.

There is Q-code display on the MB. What does it indicate?

The cable connected to the CPU says 300v on the wires, 4 wires per ribbon total of 2 ribbons going into the CPU socket. The socket has 8 pins, and the connector that goes into says CPU on it. The Q-CODE says FE in red lighting.

One interesting thing I've found, is that the only cable that doesn't say "CABLE NOT CONNECTED" and instead says "NO SIGNAL" is the VGA to VGA, and one of the vga's has longer screws than of that of the other side of the wire or on my other gold plated vga's. The one with the long side screws is the only one that has them long enough to screw in and secure, the others don't reach. Is this monitor just special? Can I simply FIX the whole issue by buying a new monitor and buying a HDMI to HDMI cable??

You can check your motherboard manual or its support page to see what an FE q-code error means but I bet it has nothing to do with the monitor.

The screws that hold the cable to the video port are irrelevent unless they somehow prevent the cable itself from being fully inserted.

You really seem like you want a new monitor. You know, you don't need our permission

Your motherboard (MB) is not running in my opinion. Q-code FE is listed as "for future use"

This is an extraction from your corsair PSU manual:

Step B: Installing the Corsair power supply
1. Make sure the power supply’s AC power cable is not connected.
2. Follow the directions in your chassis manual and install the power supply with
the screws provided.
3. Connect the main 24-pin power cable. The main 24-pin power cable has a detachable
4-pin mechanism in order to support either a 24-pin or a 20-pin socket on the
motherboard.
A. If your motherboard has a 24-pin socket, you may connect the 24-pin main
power cable from the power supply directly to your motherboard.
B. If your motherboard has a 20-pin socket, you must detach the four-pin
cable from the 24-pin connector, and then plug the 20-pin cable onto your
motherboard without connecting the four-pin connector.
4. Connect the eight-pin +12V (EPS12V) cable to the motherboard.
A. If your motherboard has an eight-pin +12V socket, connect the eight-pin
cable directly to your motherboard.
B. If your motherboard has a four-pin socket, detach the four-pin from the
eight-pin cable, and then plug this four-pin cable directly to your motherboard.

Is this correctly connected?
When you press the rest button on the MB (near the Q-code display) any change in on the Q-code display?

Yes, all the power cables are connected to the Motherboard. As for the reset, yes there are numbers that quickly cycle (done it before I contacted you guys for your guidance which I truly appreciate). I can't do it now however, will do it tomorrow and give you feedback on my findings.

Dave I appreciate your expertise and yes I do put a lot of the blame on the monitor if I'm honest, since it is quite old (only vga input) and from what I've researched, VGA is not popular at all and has caused much confusion and problems.

As for the screws, I have a VGA to VGA cable that has much longer screws than in pictures so that the thing can actually screw in properly, and If I use anything else it just says "cable not connected" because the screws on the sides weren't long enough and the monitor is "special".

If it is me to blame, how can we check the motherboard for problems, what could the issue be? And ehm, this may come as a shock to you but I'm only 14, I'm a gamer (obviously) and have learned theoretically how this all works, but never done it physically, so please consider this, thanks. So, could just buying a modern monitor with hdmi be an easy way out? My friends say yes, but you say no. Theirs an obvious issue here and I need to find out what's the problem, once again, I truly appreciate your input and it's great to have you guys.

For 14 I guess you're doing pretty good.

I guess the monitor 'knows' the difference when a cable is not connected and when it is but not receiving a signal thus giving the different responses. I can't really visualize the problem with the cable screws. I've just regular VGA connections and I don't even screw them down. If I test another computer using the monitor it's a lot easier to just pull the cable off one and attach it to the other than to have to fiddle around behind the computer case each time.

If the problem is with the motherboard you should be able to confirm that without buying a new monitor. I believe you've already connected the known-working VGA monitor to the motherboard's VGA port and it didn't work. You may want to check it again but this time clear the cmos--do that with the power cord disconnected or it won't clear right--and remove all cards, drives and USB devices as I mentioned above. Then start it up and see what happens. If you still get nothing then in my opinion the monitor is not the problem.

Or instead of buying a new one now without knowing for sure if that's what you need maybe you can borrow one from the friends who think that'll fix it.

Okay so this is what I found, without the CMOS battery:

When I turn the PSU on and the mobo lights up and I press start it says: 00 08 18 14 19 15 FE In rapid succession

When I press reset it says:

The q codes don't mean much to me other than it looks like the process just got started before it went to FE and stopped.

This google search maximus fe "q code" turned up this:

http://rog.asus.com/forum/showthrea...

where a loose/bad fitting heat sink causing an FE error. But I'm thinking the q code sequence might end at FE on any catastrophic failure so their fix might not mean anything but still it'd be a good idea to double check stuff like that.

Looking at the Q-codes it seems to fail after starting memory sequence.
I would expect it to the q-code to continue with 2B-2F.

Is the memory compatible with the motherboard?
How many sticks are inserted?
Remove one if you have more than 1 stick.

1) Wait... Maybe I found the issue? In the User Guide "MAXIMUS Vll HERO Motherboard Qualified Vendors List (QVL)" section there is no memory stick names that say my sticks name: CMY8GX3M2B2133C9R The closest stick that is in my manual to my ones is CMY8GX3M2A2113C11R or CMD8GX3M2B2133C9 - oops?

2) 2 sticks of ram. 2x4GB

3) Will try that once I get feedback on Q. 1

A google search on those 3 types of sticks show they have the same specs--2 x 4gig, 2133 mhz (that would be the main points of comparison)--but I can't say specifically what differences they might have. But I think what you're using should work OK.

Do you have a speaker connected to the motherboard pins, or does it have one of those on-board piezo speakers? If it's just memory incompatibility you should get the memory error beeps. The beep codes are on page 2-17 of the manual.

Well, I have this splitter thing I guess, it says Reset ground PWR ground HDD HDD LED - and on the other side of it PLED + PLED - and what we're mostly interested in, is SPEAKER, GROUND, GROUND, +5V which has nothing connected to it. I also have this weird thing 9 pin connector thing which says USB on the buttom the right way up, and NC GND P2+ P2- +5V on the other side of it +5V P1- P1+ GND

The first set of pins are the ones typically connected to the front of the case--power on-off, reset, HD LED, power LED, speaker. The second set marked USB are probably for front USB ports or on-board card readers.

The piezo speaker I mentioned looks like this:

http://www.erenumerique.fr/images/c...

Its diameter is about that of a dime. Most motherboards have both the pinned speaker connection (like you found) and the piezo speaker. But your manual mentioned connecting a speaker so you can hear the beep codes so it may not have the on-board piezo speaker. If you don't have one you may be able to find one of the little 2 inch PC speakers they used to put in or you can get a piezo speaker already wired for a motherboard:

But you need to connect something that's going to make noise.

From what I've observed, the board doesn't have one.
The thing that I'm annoyed at is that I can't find anything to fit in the speaker section of the splitter.

The motherboard speaker connection is usually 4 pins but only the end pins are used--1 and 4 if they were numbered. Some connections might just be 2 pins but either way it shouldn't be difficult to fashion a connection. The manual should show the exact pins to connect the speaker to.

Is the 'splitter thing' the wire pigtail assembly that goes to the LEDs and switches on the front panel? Often those won't exactly match the motherboard connections and you have to carefully remove the wires from their plastic holders and position them differently in the holders.

Just for curiosities sake, you connected the monitor to your tv to rule out possibilities through elimination?

Is there any way you can connect your pc tower to the tv to use it as a monitor?

I apologise if you've tried this, I skim read through the responses.

If your tv gives you an image then my guess is you can comfortably say the monitor isn't playing nicely with your new rig.
