No Video on boot

prem123 · Jul 13, 2009, 11:37 PM

I have a system that I built, about a year ago, and now there is no video. I have replaced the video card, cleared the CMOS, turned on the computer with just one stick of ram (total of 2 sticks, I tried each one), tried each rail of my power supply on the video card, and I have also gotten the motherboard replaced. I hear no beeps from the system at all. Now, I'm thinking its the CPU on my computer, is there anything else that it can be? I have listed my specs below

Intel Core 2 Quad Q6600
Cooler Master Hyper TX2 Cooler
Crucial Ballisitx RAM (2x1GB)
ASUS P5N32-E SLI Motherboard
eVGA 9800GT

Ensure you have 12V under load on the CPU power connection and the PCI-E power to your card ... do you have access to a multimeter?

If you have swapped the video and mobo it is possible the CPU is defective. Test your PSU first though it can cause a variety of issues if not working properly.

prem123 · Jul 14, 2009, 11:38 PM

I used a multimeter, and there is voltage coming out of the CPU and PCI-E power connector. I guess I should get the CPU replaced now. I bought the CPU from Newegg, should I call Newegg or Intel?

Mac Daddy · Jul 15, 2009, 03:32 AM

You have to test both under load which means they are plugged into the socket and working.

If you find it is a CPU issue check your warranty with Newegg first then Intel.

prem123 · Jul 30, 2009, 07:35 PM

How would I check it under a load? Also, I got a PCI diagnostic card, and the card shows nothing.

Under load in this instance means the PSU is plugged into the mobo when voltages are checked.

Your diagnostic card shows "nothing"... meaning no problems found or doesn't even light up it's display?

prem123 · Jul 30, 2009, 10:35 PM

It doesnt really give me an error code, its getting power, but the pci card has 4 leds for the voltages (-12v,+12v,+5v,+3.3v) and they all light up, so im assuming the psu works under load.

Tyrsonswood · Jul 30, 2009, 10:49 PM

I would agree from that description that the PCI slots are getting proper voltages. What about CPU power plug? Did you check voltages there?

Your original post says you had the mobo replaced, I take it you kept your original CPU but it sounds like you didn't do the work yourself, hope I'm not misreading here.

I have also gotten the motherboard replaced.

Did it work when you got it back from whoever did the replacement?

Do your drives all spin up, etc. when you power it up?

prem123 · Jul 30, 2009, 11:00 PM

No, I replaced it myself. When I power up, everything spins up, all the fans, hard drive, and the video card fan. The only things that I haven't replaced in the system are the power supply and the CPU.

Tyrsonswood · Jul 30, 2009, 11:07 PM

Okay, sorry about my confusion on that...... (they sent you a new one

) If you have proper voltage at the CPU power connector I guess it would come down to CPU.......

Anything odd right before it quit? Your original post didn't mention.

prem123 · Jul 30, 2009, 11:13 PM

Nothing odd, but how would I check the CPU connector under load (I'm pretty sure its the CPU but want to make sure)?

Tyrsonswood · Jul 30, 2009, 11:59 PM

Leave it connected to the mobo and check voltage with a multi meter, you can touch the pins from the topside of the connector...... Proper care to not touch the two probes together while doing this of course.

prem123 · Jul 31, 2009, 12:29 AM

So, I have to take the mobo out?

Tyrsonswood · Jul 31, 2009, 12:59 AM

I wouldn't think so, unless you can't get to that connector with the mobo mounted in the case. This is the ATX12V connector near the CPU...... looks 8 pin but 4 may be blocked depending on your psu....... I'm looking at your manual for this, I don't have your board.

prem123 · Jul 31, 2009, 04:03 AM

It's a 8 pin. Where would I put the connectors of the multimeter, when its plugged in?

Tyrsonswood · Jul 31, 2009, 04:31 AM

Most connectors just have the wire going into the top of the plastic plug, they are crimped there and you can see exposed metal of the pins that go down through the plug. Voltage can be measured there on those exposed metal bits. Your cables could be different and have a boot covering that, but most don't, so it should be easy access. The wires are usually yellow (+12V) and black (ground)..... if your cables are not of this type then it gets harder to check.

I'm leaning towards CPU myself, but if the ATX12V plug doesn't have voltage your CPU wouldn't run...... if it's an easy voltage measurement then it's best to be sure.

Mac Daddy · Jul 31, 2009, 01:45 PM

I am too Ty and thanks for picking this up I was in bed lol. Insufficient power at this plug under load will cause this symptom as well so worth checking. Good luck with it prem123 and keep us posted.

procupine14 · Jul 31, 2009, 04:08 PM

It almost has to be the CPU considering how odd this thing is acting. I can't see it being the PSU but I've been wrong before on my own builds

so who knows. Judging by the fact that the mobo makes no error beeps that's the only thing that I can thing of. Assuming that there isn't even a POST screen coming up which is what it sounds like I lean toward the CPU.

I've seen some pretty dead/dying PSUs and the mobo with generally at least post unless the PSU is TOO far gone then it just doesn't even power up.

Tyrsonswood · Jul 31, 2009, 11:08 PM

I think several of us are thinking CPU, but if the 12v to the CPU (ATX12V plug) is dead on the power supply it would give the same response as a bad CPU.... easy check that could save some $$$

prem123 · Aug 1, 2009, 01:20 AM

Well, there isn't really a way i can get the connectors of the multimeter in, since the CPU connector is near an edge of the case. So if its the CPU, should I contact Intel, or Newegg (who I bought it from)?

Tipstaff · Aug 1, 2009, 02:01 AM

Just out of curiosity, you said you tried all the different combinations of things, such as using 1 stick of ram and such, but did you unplug the power for all your optical/hard/floppy drives, as well as their data cables from the motherboard side?

A few other things:

1) what eternal devices do you have connected, if any? Obviously a mouse and keyboard, but what type? USB? If you can, try a PS2 keyboard only.

2) Unplug all case connectors from the motherboard except the one to your power switch.

3) Do you know the bios version for your current board, and which stepping version of the Q6600 you have? The B3 or G0 version? The reason I ask is that for the B3 version you only need bios version 0501 installed or higher, but for the G0 version you need 1103 or higher. If you can, try a different, but older CPU, like a P4 or Celeron D. These are supported by the original bios for the board, and as such would allow you do update the bios to the version that supports your current CPU.

prem123 · Aug 1, 2009, 04:03 AM

No, I didnt unplug power from the rest of the components. I have a USB keyboard/mouse plugged in. I think its a G0 (its the one thats better at overclocking). This was all working normally. Then I got no video once in a while, It would fix itself if i unplug the system and plug it back in. Now, its just no video at all.

The reason I mention the USB part is that I've run into situations where a computer would not boot at all due to a busted USB device. In your case I would even try removing all USB devices to see if it boots up.

A couple other things to try:

1) Remove all your RAM, and try booting the system. Yes, it sounds stupid, but the idea is to force your motherboard to bring back an error... which if you remove your RAM it should do so, loudly, usually with long continuous beeps. You said you replaced both your motherboard and video card, but if I read correctly the CPU and the RAM are still the original parts. The idea here is to see if your RAM is an issue.

2) Along with the above, since your board has no onboard video, removing the video will also generate an error code too (with 1 long, and 2 short beeps). This is more of a test to see how the board responds.

* of note, if you followed my advice about disconnecting all the case connectors, then be sure to reconnect your case speaker to your board, otherwise you won't hear the errors. *

prem123 · Aug 2, 2009, 07:33 PM

Well, I do not have a case speaker right now, I had to borrow one from my friend, but hes out of town. Do you think a PCI diagnostic card would tell me the errors instead?

Hard to say. I guess it depends on whether the card can work independently of the system bios or not. I've seen some expensive ones that work regardless, but I've seen cheap ones that require the system to partially boot, where it needs the system to have posted, even if partially, to work.

prem123 · Aug 7, 2009, 09:29 PM

The PCI card doesn't really tell me anything, I think I'm going to just get the CPU replaced. By chance, does anyone know the number to contact Intel?
