Question about Acer AM5641-B5560A Desktop PC & Monitor BUNDLE
No graphics? As in No Signal shown on the monitor?
Indeed it could be a graphics 'engine' problem, in that the Integrated Graphics, (Nvidia GeForce7100 ), could be bad.
Integrated Graphics is also known as OnBoard graphics. ON the motherBOARD.
The GPU chip is soldered directly to the motherboard.
[GPU = Graphics Processing Unit
Nvidia GeForce 7100 integrated graphics GPU,
No Signal = No video signal The computer isn't sending a video signal to the monitor, or if it is, it isn't getting to the monitor.
Do you have a Known to be Good monitor cable, to swap out with the existing one, OR, do you have another working computer to use THAT monitor cable on?
The monitor seems to be working fine. Monitor cable checks out? The next logical step is to assume a bad GPU.
However, experience has shown me that the next area to check, is the Power Supply.
Bad Power Supply, weak voltage power rail.
A bad Power Supply is one of the leading causes of computer failure.
Most of the time due to the inside of the computer, as well as the inside of the Power Supply, has been neglected in cleaning.
A can of compressed air for computers, used on a regular basis as needed, can prevent this.
However, not to slam your Acer, but this manufacturer is known to install inferior low quality Power Supply's.
The Power Supply in your Acer, is of a design used in many personal computers.
An SMPS Switched-Mode Power Supply.
Left-click on the photo to the upper right. This will enlarge the photo.
There are two cooling components for an SMPS.
1) The Fan
2) Internal Heatsink's used inside.
[Heatsink: Basic construction of a Heatsink is a flat plate of metal, that has tall, thin fins protruding from it.
The plate of metal absorbs heat from whatever object, it is placed against.
The tall, thin fins radiate the heat away. When a fan is used in conjunction with a Heatsink, the air flow from the fan helps carry the heat away from the fins ]
When these two cooling components are coated with a layer of dust, dirt, etc., the cooling capacity drops tremendously.
Heat = Wasted Energy
The Power Supply tries to keep up with the call for power, but eventually cannot due to heat, and wasted energy, and components inside fail.
The Power Supply fails.
There are three major power rails for the Power Supply you have.
A) The 3.3 Volt power rail
B) The 5 Volt power rail
C) The 12 Volt power rail
(Termed power rail, because each voltage comes from one single source inside the Power Supply.
There are power cables which come from the Power Supply, and carry Voltages.
Orange insulated wires carry 3.3 Volts
Red wires carry 5 Volts
Yellow wires carry 12 Volts.
All these power wires start at one power rail 'point', inside the Power Supply.
A) ALL of the LED lights for your computer use less than 1 Watt of power.
B) EACH fan uses 2 to 3 Watts
C) A typical Processor can use from 51 to 125 Watts.
Depends on what Processor it is.
Acer Aspire AM5641? Supposed to come with an Intel Pentium Dual Core E2200.
This Processor can use up to 65 Watts,
You could have LED lights lit, fans spinning, (Or spin a few times then stop), and it may even sound like the Platters inside the Harddrive are spinning, but you may not have enough power to turn the Processor on.
No Processor operating, No computer.
No computer, No video Signal to the monitor.
Test the Power Supply, or use a Known to be Good, Compatible power supply for a test unit.
1) Has the correct power cables needed
2) Has the correct amount of power cables
3) Is the correct form factor (Size and shape of power supply case, essentially for this explanation)
4) Has enough Wattage ]
(Just love it when I post a Solution as a Clarification!)

Sounds like your on board graphics are gone. since you have a PCI-e card slot you can buy a PCI-e graphics card and install it. that should do the trick.
