Black out can be caused by series of things. Power supply is one. Second is the motherboard, memory and the processor aside from the video card. Motherboard and processor can be isolated,first is to remove the rest of the devices such as hard disk and cards and memory. Beep sound means your board is still doing fine. Re install all the devices and power on again. Good luck

My acer aspire m3641 just shows black screen


Is the computer booting? Fans spin? LED's blink? Sound? Have you tried another monitor? If so, check and reseat ALL cables. The specs indicate you have Integrated NVidia 7050 Graphics Adapter. You may need a aftermarket PCIe x16 Graphics Card to install in a open slot. Verify the cables are good and the monitor works on another computer first.

I got an acer asprine M1640 but when i start it its keeps beeping short beeps and it wont start a friend of me said it was something with the videocard when i replaced it it stayed the same it kept beeping...


Bad Power Supply

Weak voltage power rail

Do you, or your friend have access to a multimeter? An economical unit can be purchased for as little as $8 to $12. Available in a multitude of stores. An auto parts store is but one example. Analog or digital is fine.
This way you can test the 3 main voltages coming from the Power Supply.

A) 3.3 Volt power rail
B) 5 Volt power rail
C) 12 Volt power rail

(All DC voltages. In comparison, two D cell flashlight batteries store
3 Volts DC. { 1.5 Volts each )

OR; do you have a KNOWN to be good, Compatible power supply you can borrow for a test unit?
Compatible: Has to have at least the same Wattage, or more, and has to have the correct power cables, and number of power cables needed.

Primer:
1) If ALL of the LED lights were on at once, they would use less than 1 Watt of power.
2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor can use 51 to 125 Watts of power. Just depends on what Processor it is.

Your Power Supply doesn't have enough power to 'b-low it's nose'.

Nothing shows on monitor? It isn't going to. No Signal. No video signal.
This is because the computer isn't sending one. Why? Because the computer isn't working.

Let's start with this. Post back in a Comment as to your results.

Reset the cmos usualy a jumper, or remove the batery for 10 min, it might be a videocard problem, try another videocard. It might be a memoryproblem.

My acer aspire m1640 crashed and now when i turn it on nothing happens the monitor says no signal


Sound like a bad motherboard.You are getting the error because no signal is been sent to the monitor. Make sure the memory is inserted properly and firmly. Check all other cards and plugs are all inserted and firmly sitted. and try to boot the system, if nothing stll happen, you may have a bad motherboard
