Having problems with your Acer Aspire m5640 PC Desktop ?

Acer desktop mouse,keyboard not functioning, monitor also not wor

\015 Acer Aspire Desktop- keyboard and mouse will not work. monitor turns on with a check video cable then goes black\015

Answers :

If there is no display on the monitor, then your computer is not sending a video signal to the monitor.
This could be caused by a bad video card or some other hardware problem. I would open the case and disconnect all the devices (hard drive, CD, etc. Leave only the CPU, memory, and video connected. You could leave the keyboard and mouse connected too.
If your computer then starts, you can start to add devices (after turning the computer off) one at a time.
If this doesn't work, then you are looking at replacing the motherboard or just the video card if that is possible.
Does your pc have a graphics card? and is the monitor video cable plugged into it or into the on board graphics port?

Recently, I purchased an Acer H233H LCD Monitor with the HP e9180f Desktop. However, the built-in stereo speakers in the monitor are not working. The sound card in the desktop is fine, as headphones and my dad's external speakers work fine when plugged in. The monitor has a seperate volume control, which is also turned all the way up when testing the monitor speakers. As I do not want to go out and spend more money purchasing good external speakers, any suggestions?
