Solved No signal to monitor!!!!!

June 8, 2012 at 06:36:11
Specs: Windows 7, Intel celeron 1200
No signal to monitor when running through my graphics card, this graphic card has been working in this pc for over 12 months and then it dropped out. The graphics card work in other pc's. I have cleared the CMOS, that didnt work. When I remove the graphics card and use the built in VGA port everything works fine but as soon as the graphics card is back in there is no signal to the monitor. There is still power to the graphics card as the fan on it runs. Any help on how to fix this???

Your mboard was made by MSI - they are known to be more likely than average to have this problem....

Some mboards develop this problem - electrolytic capacitors were installed on them that were not properly made, and they fail eventually - the mboard manufacturer didn't know they were improperly made at the time the mboard was made.

Open up your case and examine the mboard to see if you have bad capacitors, and/or other findable signs of mboard damage .

What to look for, mboard symptoms, example pictures:

- he says there are STILL bad capacitors on more recent mboards.

........

If your mboard shows signs of failing capacitors, you must either....

- replace the mboard.
However, if it does have improperly made electrolytic capacitors, the problem is likely to happen again in the future with either of the identical replacement mboards this model came with.

- or - replace ALL the physically larger capacitors that are the same brand as the ones that failed, otherwise the problem is likely to happen again the future,

or have a professional like the Badcaps guy do that for you (He only accepts and ships mboards from / to the US and Canada - e.g. there is a web site located in Europe that does the same thing - he may ship to anywhere .)

.........

If your mboard shows NO signs of failing capacitors,......

You have several choices.

'When I remove the graphics card and use the built in VGA port everything works fine ..."

- No cost - use the onboard graphics, but that may not be suitable if you play games.


- Modest cost, or no cost if you already have one - install a decent PCI video card.

Pro - if the PCI video card has a more recent video chipset, it will still work very well with games, much better than the onboard video.

Cons
- installing a PCI video card does NOT automatically disable the onboard video, and there is NO setting in the bios Setup that can disable it. It will still be sharing part of the ram installed in the mboard. If there is a setting in the bios for that, reduce the amount of memory shared with the onboard video to a minimum.
You can choose to Disable the onboard video in Windows in Device Manager by when you RIGHT click on it, but it will still be sharing part of the installed ram.

- sharing ram with the onboard video limits the max data transfer rate the ram would have otherwise been able to achieve if the onboard video was disabled by installing a card in a PCI-E X16 slot, by as much as half Programs such as high end games that benefit from a high data transfer rate will not work as well

Note that the last PCI slot closest to the center of the mboard usually shares it's IRQ with the video, the onboard video in this case since the PCI-E X16 slot probably isn't working. It's not a good idea to install a PCI card in that slot other than a PCI video card - you're likely to have problems. Otherwise, you can install a PCI video card in any PCI slot it works properly in,

- More cost, unless you already have one or can get one cheap - replace the mboard and use the same CPU and ram.

You can replace it with any Socket 775 mboard that supports the CPU you're using in it's CPU compatibility list, however
- the HP / Compaq Recovery disk set for your model will probably REFUSE to install unless the mboard is the same one with it's Compaq bios version.

- brand name system builders usually use one piece connectors from the case that were designed to be used with headers with certain specific pin outs. HP has no info about the pin outs for your OEM only MSI mboard (made only for brand name system builders - there is no retail model that is the same - MSI has no support for the mboard model). If you buy a mboard that has different pin outs for the headers on it, you have to change which wire goes where on the headers, or chop them off and use wiring with generic connectors, etc., etc.

So - you're better off buying one of the possible mboards that originally came with the system that has the Compaq bios version.

Apparently SR5520AN originally came with a 300 watt PS.

Your power supply must have at least the minimum capacity required to support a system with the graphics card you are using installed, or the max graphics card you might install in the future.
(Onboard video - video built into the mboard - IS NOT A CARD ! )
If that info is not in the ad for the video card, you can go to the video card maker's web site and look up the specs for the model - often under system requirements - the minimum PS wattage, and, more important, the minimum amperage the PS must supply at 12v is stated. If you don't find that, any card with the same video chipset including any letters after the model number has very similar minimum PS requirements. Some power supplies have two or more +12v ratings - in that case, add those ratings to determine the total +12v current capacity.

Tell us the make and model of your brand name system, or if you have a generic desktop system, the make and model of the mboard.

The model, sometimes the make, of a mboard in a generic desktop system is usually printed on the mboard's surface in obvious larger characters, often between the slots.

The specific model of a brand name system is often shown on a label on the outside of the case somewhere, or it can often be determined by going to the brand name's web site and loading a program they have available, if Windows is still working, on the subject computer.
.........

If you always have video while booting BEFORE the operating system is supposed to load, but no video AFTER the operating system is supposed to load, that is a DIFFERENT problem from never having video, and that's usually EASY to fix on a desktop system.

No video while booting BEFORE the operating system is supposed to load can only be caused by a hardware problem, UNLESS the main chipset of your mboard supports Hybrid video.

Some AMD, NVidia, and Intel main chipsets support Hybrid video of one sort or another - both the onboard video and the video on a card in a PCI-E X16 slot working at the same time. In that case, improper settings , or default settings, in the bios Setup CAN cause no video from a video card installed in a PCI-E X16 slot, and in that case, the onboard video is STILL enabled by default, and settings in the bios Setup must be changed in order to get video from the PCI-E X16 card.

If the main chipset DOES NOT support Hybrid video, then there is NO SETTING in the bios Setup that can result in you not getting video from a single video card in a PCI-E X16 slot while booting BEFORE the operating system loads

"I have cleared the CMOS, that didnt work."

Bios Setup settings the user has made do not spontaneously change. If you did not change any bios settings just before you first got your symptoms, you problem is not caused by bios settings.
In any case, bios settings, or whether the Cmos battery is even installed, have / has NO EFFECT regarding you getting video from the video card in a mboard slot, UNLESS the main chipset of your mboard supports Hybrid video.

"The graphics card work in other pc's."

Does it work in other computers NOW ?

If YES....

"When I remove the graphics card and use the built in VGA port everything works fine.but as soon as the graphics card is back in there is no signal to the monitor. There is still power to the graphics card as the fan on it runs..."

If your mboard does NOT have a main chipset that supports Hybrid video, the most likely cause of your problem is either the power supply is inadequate, or it has become defective or has been damaged.

Tell us which subject video card you have.

Tell us the make and model of the power supply, and what it's rated (max output) wattage capacity is.

Is the power supply exhausting obvious air out of the back of the case where the power supply is mounted ?
If it isn't, the fan inside of it has failed, and the power supply has probably overheated and has DAMAGED itself.

We have frequently heard of problems caused by the power supply being inadequate for the requirements of a system that has a video card installed in a mboard slot.

Your power supply must have at least the minimum capacity required to support a system with the graphics card you are using installed, or the max graphics card you might install in the future.
(Onboard video - video built into the mboard - IS NOT A CARD ! )
If that info is not in the ad for the video card, you can go to the video card maker's web site and look up the specs for the model - often under system requirements - the minimum PS wattage, and, more important, the minimum amperage the PS must supply at 12v is stated. If you don't find that, any card with the same video chipset including any letters after the model number has very similar minimum PS requirements. Some power supplies have two or more +12v ratings - in that case, add those ratings to determine the total +12v current capacity.

If the wattage capacity and/or the max current rating at +12 v of your power supply is more than a little less than the recommended value(s) for the video chipset on the card, the video card may work anyway, but the power supply is being overloaded when the card is installed and eventually the power supply's components will be DAMAGED. When the power supply has been damaged, it may either fail completely, or it may not longer be able to support the current requirements of the card when the card vis installed, yet the system may work okay when the card has been removed or if you use a card that has lower current requirements.

In any case, it's common for power supplies to malfunction or fail completely, the lesser the quality of the power supply, the more likely that is.

Some el-cheapo power supply brands are well known to be a lot more likely to cause you problems. E.g. BESTEC, frequently used in eMachines desktop computers, and in some Acer and Gateway computers, and in some cheaper models of other brands.

The only way to rule out the power supply as being the cause of your problem FOR SURE without you having to buy one is to try a power supply that has at least the recommended wattage capacity from a working system with your system, if you can.

The graphics card is a Nvidia GeForce 8400 and does not require addition power from the power supply. The graphic card currently works in other computers. I have tried another graphics card in the pci express slot and it has failed to work also. I only have one pci e x16 slot on the motherboard so I can not try anything else. The computer make is a Compaq Presario SR5520AN I have also tested the ram and that does not seem to be the problem. I have also just tried a 1000 watt power supply used in one of my gaming computers and that did not change anything

" The graphic card currently works in other computers. I have tried another graphics card in the pci express slot and it has failed to work also."

If the other graphics card works, and will work when system has the PS wattage the PS has......

In that case, the ONLY things that can cause that are the PCI-E X16 slot circuits are damaged, or the mboard has become defective or has been damaged otherwise.
