Acer Aspire 5601 4GB memory upgrade problem

try to windows xp SP3.

I had same problems before on installing Windows Xp service pack 3 that some component of your computer is not working well webcam not working and others. I believe that the hardware components of the service pack 3. Try to install other operating system like service pack 2 and upgrade for SP3 is available or other.

Surely to load XP is a DownGrade. As this notebook is dual core, I would run Vista 64 or better still Windows 7 64.
If you wish to persist with an old system, you require SP3 for XP.That may be available from a software store but is no longer supported by Windows.
Try http://www.notebook-driver.com/laptops-information/acer-aspire-4520-notebook-technical-specifications/ for drivers that you will require to have support from Acer.

Hope that clarifies your situation.

Click that link and download all the drivers you need.

pls rate this post!!!

I personally have not but if you are concerned how it will run, you should be fine, windows 7 is very efficent on resources.

• 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
  
• 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
  
• 16 GB available hard disk space (32-bit) or 20 GB (64-bit)
  
• DirectX 9 graphics device with WDDM 1.0 or higher driver
  These are system specs so if you exceed these then your laptop will run great.
  
  Hope this helps
  

Pls Check this link, in reference to your memory upgrade...it seems that your laptop could only accomodate max 1Gb of RAM

Go to Start - Run - msconfig. Go to Startup tab and disable all unnecessary programs. try to increase the virtual memory size, or upgrade RAM memory if possible.

Try the XP version again for the second time.
