  • Can't be sure: these were just ideas I had.
  • Depending on how you reinstalled Windows 7, you may need to install the drivers for your network adaptors via another computer, since if the drivers for WiFi and/or ethernet are not yet installed, you will not be able to download anything or connect to the Internet or any other network. Can this be the case? Clive
  • It seems unlikely to me that the tests themselves would be the cause of product key being blocked. I experienced a Windows XP product key being blocked after several attempts to install on an SSD (what Microsoft may have automatically considered to be too many attempts). I found the support from MS useless where I was…
  • I have a similar problem with an IBM R51, although the HD does start up. In my case, it looks as though the motherboard is defective, but it's not worth my while to replace it as it's a second (third) computer for me. RAM should ideally be compatible with what you have already installed: type (DDR2,3) speed (e.g. 667MHz)…
  • By "power cable" I assume that you mean the "charger" or "AC adapter". Generally speaking, these are generic for many different models and versions of models of computers from a particular manufacturer, so one will work for many. What's critical is that the voltage (V) is the same and that the charger supplies enough…
  • I am afraid that it looks as though you are correct, at least as far as I can tell from my (quick) research. The alternative is to reduce the amount of memory that the operating system is using, including the essential utility programs (like antivirus/anti-spyware), stopping programs and services running in the background…
  • From what I can see your laptop will take a maximum of 8GB but with 32 bit it can only use around 3.5GB maximum. You can see how much RAM you have installed by clicking on Start then select computer and right click to select Properties. Under the heading "System" the amount of Installed Memory (RAM) is specified. If you…
  • Sounds to me that you'll need a hardware repair/replacement. There are several things that might cause such an error, but I'd imagine that something about the laptop is damaged: the hard drive, it's connector, the motherboard, something else, and how much it's going to cost is impossible to say. Good luck! Clive
  • Reinstalling the driver(s) can fix the problem, even if they seem to be correct and up to date. I don't have the experience of the Acer having this issue, but I did have to reinstall the wireless network adaptor driver of an HP Pavilion DV6 (known issue) to fix the lack of wireless connectivity that I experienced. What…
  • Thanks Tommy. Am I correct in thinking that all of these are LED backlight screens? Clive
  • Well I might suspect the graphics card/GPU first, although RAM is easier to change. Clive
  • I can't say about replacing the screen on this model and I could not find the part listed at eBay. I am in the process of replacing the (conventional, non-touch) screen of an Aspire 5742, which is relatively simple requiring some basic electronics skills, and for which I found quite good instructional videos at YouTube.…
  • It seems to me that perhaps the mouse has stopped working properly for whatever reason. I am not familiar with this particular model, but I know that some computers have the capability to turn the mouse on and off: could this be the case here? Best of luck Clive
  • Downloading from the internet is the usual method, or alternatively from a USB pen drive of sufficient size; for professionals from the network via the ethernet connection. If you have the programs available only as CD's/DVD's either you can copy the contents to a USB pen drive using another computer that does have a…
  • Be careful when "doodling with the function keys"! Joking aside, that's a little strange with the wireless. You might try connecting using an ethernet cable as an alternative to using wireless, if that's available to you, or as I suggested to someone else, going somewhere where there is public WiFi access, in case the…
  • I think this could be a hardware error, possibly with the web cam itself, or the connection, but it's hard to be sure. It seems as though the operating system is looking for the camera, but not finding it, which would seem to suggest that the OS and driver are working. But it does not hurt to download and reinstall the…
  • Dodgy, yes. Do any other lights light up and/or can you hear the hard drive or fan starting up? I am in the process of replacing the LCD panel of the screen of an Acer Aspire 5742 belonging to an aquaintance. I can detect that the LED backlight built into the panel has stopped working: by shining a strong light onto the…
  • A driver gone bad can also be the cause, and can be fixed by reinstalling the driver for whichever network adaptor you are using. Are you connecting to the modem via WiFi or Ethernet cable? Whichever you are using, you can use the other method to see if the problem is with the computer, or the modem or the service. Also,…
  • Have you tried to reinstall the relevant driver? Clive
