SOURCE: Trouble booting.

Try ctrl + alt+del on the desktop and see if the task manager comes up. With it, you can take a look at the running processes and see what's hanging the system. It sounds like malware is a likely candidate.
See malware removal forums here, and others in the last post there.

First you need to shut down and plug in an external PS2 or USB mouse so you have control of both buttons. Then boot up and go to the Acer web site or to the Synaptic web site and download and extract the latest updated driver for your touch pad. Go into control panel ' system ' device manager ' pointing device, Then right click on the touch pad and click the driver tab and then the "update driver" button. Browse to the folder where you downloaded and extracted the new drivers and install them. Shut down your machine, unplug the external mouse and re-boot. If it is still doing the same thing, then you have a hardware problem and you will have to replace the touch pad unit. You can probably buy one off eBay for a lot less than Acer will charge you for one. If it is still under warranty then ship it back. As a side note, it is helpful if you also post what operating system and service pack you are running.

VGA modes are old VESA standard video modes that are supported as legacy modes on most graphics cards. In general, on modern graphics cards, they have variable refresh rates so as not to cause problems with monitors that can't handle the lower refresh rates frequently associated with VGA modes. Sometimes, graphics cards do not adjust the refresh rate for the monitor, and this can cause problems of minimum refresh rate being exceeded. The LCD monitor possibly has a very strict minimum refresh rate, and thus cannot handle the VGA mode on its standard refresh rate as sent by the graphics card.

SOURCE: Computer not responding at bootup

If it works in safe mode, it is not a hardware issue but rather a software issue. You didn't mention what Operating System you are using (which version of Windows), but if you go to msconfig and run a selective startup, eliminating things that you don't need, you might be able to track down the offending item.

Freezing upon start up of computer


The best solution for you amanda would be to do a complete re-installation of Windows Operating System. As you can log in via Safe Mode, run the Recovery Manager from there so that your laptop is being set to Default Factory Settings.

Also, if you found it hectic, then here are a few tips to get your system going:

a) From Safe Mode, uninstall your antivirus program.

b) While in safe mode, restore your computer to an earlier restore point where you think the computer was working fine.

c) From Safe Mode, uninstall the programs which runs while you log in the windows

Cursor problems


Boot up in Safe Mode and see if you can use the touchpad. It might have been hijacked by a virus or infection.

Turn off the computer, then hit the power button to turn it back on and immediately start hitting the F8 key repeatedly until you see SAFE MODE. Take the Safe Mode With Networking option (this will give you internet connectivity) and let it boot up. Safe Mode will look different to you, the screen will be darker and the icons bigger, this is normal. If the cursor and touch pad seems to be ok open your internet browser to download and install MalwareBytes and run a Quick Scan.


Go to www.google.com and in the search box type: "Download cnet Malwarebytes" (without the quotes). Download and install malwarebytes from the sites download.cnet/malwarebytes. When the site opens up click on the Green Download button on the left. Do not click the Red Download button, that's junk. When it finishes installing the Gui Interface will open up with an offer to Accept a Trial Version or Decline. CLICK DECLINE you want the totally free version. Run a QUICK SCAN. As it scans, if it finds infections the number will be in red. When it finishes scanning, click SHOW RESULTS. A notepad text document will open up showing you the results. You can close the text document and go back to the Gui Interface where you will click REMOVE SELECTED RESULTS. The objects will already be selected for you. When it finishes removing the objects click ok and it will sometimes reboot your machine.




Click Start/Control Panel and look for the Mouse and open it to check the mouse properties. Make sure you don't have the touchpad disabled.

Some models will allow you to toggle the touchpad on or off by clicking on the button that is located at the top of the touch pad in the middle.

Some models will allow you to toggle the touchpad by tapping twice in the upper left hand corner of the touchpad.

Some models will require a keystroke to toggle the touchpad. Press and Hold the ALT or FN function key located at the lower left portion of the keyboard, then hit the key that toggles the touchpad. The correct key to hit will have the icon of a finger pointing at a square that represents the touchpad.

Download and reinstall the touch pad drivers.

Get online and got to www.google.com In the google search box type: "Dell Support" (without the quotes and put your manufacturer name before Support). Look for downloads and drivers. Enter your model number and operating system when requested. Download and install the Touchpad drivers.

My cursur is not moving,how do i fix it


Does the mouse pointer move? Does the mouse work? Does the Keyboard work?

The cursor moves on keystrokes from the keyboard or from taking the mouse and pointing it and clicking in a text area.

make sure you have not turned the touchpad off. Some laptops will have a button that is located in the middle of the touchpad at the top of the touchpad that toggles the mouse pointer on and off.

Some laptops will have a set of keystrokes that toggles the touchpad on or off. Normally you will have to Press and Hold either the Alt or FN key then hit the corresponding key that controls the touchpad. Most times the correct key to hit will have the icon of a finger pointing at a square box that represents the touchpad.

You may have been hijacked by a virus or infection. Boot up in Safe Mode and see if it works.

I am connected to wifi on the netbook but when I click on internet explorer nothing happens. when I click on my computer or recycle bin the screen flashes but will not open them.


You are infected with a virus. Download Malwarebytes anti malware from this link. (CLICK HERE) You will have to do this from another computer and save it to a flash drive or disk then transfer it to your computer. Install the program, update it, and run a full scan. If you have problems installing it you may have to enter your computer in safe mode. (press F8 as the computer first begins to boot up and select safe mode) You may need to re-install internet explorer after virus removal. (CLICK HERE) for IE8 download.

"windows will shut down in 30 seconds, please save your work ...


By the information provided by you, it seems like the issue may be Hardware related.

Restart the computer and press F5 and boot Computer to Safe Mode. Check if the Computer is still restarting.

If the issue still persists, try reinstalling the Operating System. However, if the issue still persists then it confirms that it is Hardware related.

If the Computer does not restart in Safe Mode, then the issue is with one of the Driver or any recent program or Virus. Try reinstalling the Drivers and uninstall any new new programs installed. Also scan the Computer for Virus.

You can also happen due to the presence of bad sectors in the Hard Drive. In the Safe mode, try performing Disk fragmentation to remove bad sectors and check if it resolves the issue.

If the issue is Hardware related, then the part that has to be replaced is Hard Drive. This is because, the Computer is booting to the OS. Hence it is completing POST and indicates all the other essential components are working.

Computer has viruses which might be why it has a the blue screen


Try entering safe mode and doing the virus scan:
  • Switch on your PC
  • Before the Windows Logo screen appears press F8 to get the startup options menu
  • Chose Safe Mode
  • Once your computer boots, run AVG and let it remove all the viruses. Reboot and it should go into Windows as normal.You might have to rerun the scan a few times to get rid of everything but it should do the job.

I have a virus and stmanteec antivirus notification keeps popping up on my screen: What can I do??? Help Scan type: Auto-Protect Scan Event: Threat Found! Threat: Trojan.Zlob File: ...


If you have a virus you can not delete or if your system will not boot up correctly and you suspect a virus is the problem, a recommended solution is to start your computer in safe mode and run a virus scan. By running your computer in safe mode, non-essential processes do not start and non-core components are disabled. In other words, only the minimum necessary programs will load. Tough to remove viruses, spyware and other malware usually have no chance to run and disrupt your system and can more easily be removed.
**To run a virus scan in safe mode, you must have active anti virus software installed on your computer.
To run a virus scan in safe mode, follow these steps:
  1. If your computer is on, shut it down
  2. Power on your computer
  3. Immediately after you power on your computer, repeatedly press the [F8] key (about once per second)
  4. In the Windows Advanced Options Menu screen, use the arrows to select Safe Mode and presss [Enter]
  5. Select your current operating system and press [Enter]
  6. Select the user you would like to login under (if applicable)
  7. When your system finishes booting, click the Start button on your task bar
  8. Move your cursor over All Programs and navigate to your anti virus program
  9. Click on your antiv virus program to run it and follow the anti virus program’s normal steps to run a virus scan
  10. After the virus scan is complete, Delete all detected viruses
  11. Close out of your anti virus software
  12. Restart your computer (it should start in normal mode)
