|"Product: E-systems / Ei304"|
If that is the subject computer, I have no idea whether that's a laptop or a desktop computer.
Which is it ?
E Systems is apparently a.k.a. as EI Systems and appears to be a now out of business brand that formerly sold in the UK and in Europe.
It appears they sold both desktop and laptop computers.
The only EI Systems models I've found information about all appear to be used laptop models, or possibly old stock new models.

If this is a laptop model.....
Have you dropped this laptop, or have you subjected it to a physical jar, or have you spilled liquid on it, or have you exposed it to liquid, since it last worked ??
If yes, your laptop probably cannot be fixed.
If no, when was the last time the main battery was replaced ?
Most fairly modern laptops will NOT run on the AC adapter alone, and will NOT run if the main battery does not have at least a minimal charge. OLD main batteries (older than 2 years) are likely to develop internal shorts that prevent them being charged up enough. If the main battery gets HOT rather than just warm when you attempt to charge it for awhile, it's probably internally shorted and you must replace it.
Laptop no video (or video problems), and battery, AC adapter, power jack T shooting.

If this is a desktop computer.....
The most likely thing is your power supply is failing.
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 minumum 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.
