|The term CARD is frequently mis-used. |
If the video adapter, or any device adapter, is built into the mboard - onboard - and cannot be removed, IT IS NOT A CARD !
Searching using: MCP73VT-PM
....finds this web page for this mboard on an excellent third party site about emachines systems:
ECS MCP73VT-PM Mainboard (unofficial info)
It has onboard video - a video adapter built into the mboard.
It that's what you have your monitor plugged into, if there was nothing else wrong with your system, then the video should work fine !!
You could try your monitor with another computer, but there's probably nothing wrong with it.
If you have an actual video CARD installed in the PCI-E X16 slot,
- the onboard video port will NOT produce video - the onboard video is disabled automatically by the bios when there is a card installed in the PCI-E X16 slot.
- you MAY need a power supply that has more capacity - see BELOW below.
If you DO have this mboard in a emachines system case.....
A BESTEC power supply malfunctioning or failing is probably the NUMBER ONE REASON an emachines desktop system fails to boot normally !
emachines desktop computers usually have a BESTEC power supply.
BESTEC power supplies have a reputation of malfunctioning and failing a lot more often than average, and when they do that, they are a lot more likely than average to damage something else, especially when they fail completely, often the mboard.
If you DO have a BESTEC power supply, that's probably what is causing your problem.
If you remove it before it gets any worse and try a known good power supply with the system, if you are fortunate and the BESTEC power supply hasn't already damaged the mboard, the system will work fine.
If you can borrow a power supply from another working computer, try connecting that.
If it is failing, you can usually replace it with any decent quality standard sized standard ATX PS with the same capacity or greater.
Standard (PS/2) power supply size - 86mm high, 150mm wide, 140mm deep, or 3 3/8" h x 5 7/8" w x 5 1/2" d , or very close to that, though the depth can be more or less for some PSs.
Don't buy a BESTEC power supply !
Don't buy an el-cheapo (in quality) PS.

The e4all web site lists a manual download for this mboard model, but he is no longer allowing downloads. (If you donate to his web site, he may allow downloads eventually.)
Clicking on the download yields an error message that shows ECS_GF7050VT-M5.zip at the end of the location URL.

GF7050VT-M5 (Home support page)
There's a manual download there.
That's a retail model and may not be 100% identical to the OEM only MCP73VT-PM model, but it has the same NVDIA GeForce7050 and 610i chipsets.
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 you're a gamer...
In most if not all cases, the max capacity rating of the PS is an intermittent rating. It's recommended that you do not load your PS to any more that 80% of that rating if you are going to be using something that puts a constant load on it, such as playing a recent game for hours on end. In that case, you multiply the min capacity stated for the system with the particular video chipset on the card by 1.25 to find the min. capacity of the PS you should get.
If you need to get a PS with more capacity, you can usually replace it with any decent quality standard sized standard ATX PS.
