"The power supply is fine so is the cpu"

If the system won't boot, how do you have any idea if either of those components are still good?

Post your complete system specs in detail.

Definitely living up to your name, post back when you can do better. I'm not going to google those model numbers. But you didn't state how you know the CPU & power supply are fine. Is it a 250W? What's the matter, couldn't find anything smaller? lol

"MCP73VT-PM" is an ECS OEM only mboard model, as in, it's made only for brand name system builders and ECS has no info about it on it's web sites.

It's used in emachines desktop systems, and possibly other brand name system models.

If you have an emachines system, it probably has a BESTEC PS. Even if you don't have an emachines system, some models of other brand names were made by the same builder emachines systems are made by - Trigem, in Korea - and they may have a BESTEC PS too.
BESTEC PSs are well known to be A LOT more likely than average to malfunction or fail completely, and when they do that they are A LOT more likely than average to damage something else, often the mboard.
If you DO have a BESTEC PS, if it is still partially working, if you replace it BEFORE it fails completely, your mboard MAY still be okay, and in that case the system will work fine with a replacement PS.

Failing power supplies are common and can cause your symptoms.
Check your PS.
They often partially work, fans and hard drives may spin, leds may come on, yet you may get no video and the mboard will not boot all the way.
See response 4 in this:

If it is failing, you can usually replace it with any decent 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 an el-cheapo PS.
See response 3 in this:

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.
