Hi,

This sounds like a possible virus thats hidden on your flash drive and the fact that the hard drive may need checking for bad sectors too. Bad sectors will cause all kind of problems from the operating system not installing properly to programs not working and the system hanging.

First of all reformat the flash dive and use a virus free computer to download a decent antivirus program like AVG Free for example.

Secondly you need to run Check Disk to check the integrity of the hard drive and possibly recover any bad sectors or clusters.

To run Check disk do this >>>>

For Windows XP click on the Start Menu and click on Run. Type cmd in the box and press enter.
For Vista/Win 7 click on the Start Menu and in the search pane type cmd and hit enter.

A command window will open up.
In that command window type chkdsk /r (make sure you leave a space between the k and /)
Hit the enter key. You will get a message that says the drive cannot be locked and would you like to scheule a disk check next time the computer restarts. Type Y, hit enter and then type exit.

Restart you machine and it should scan and repair the hard drive. If goes straight through to the operating system restart the computer again.

The check disk can take a good few hours to complete depending on the state of the hard drive so please be patient.

After the check is complete see how the computer is running. If your happy with it then see if the antivius software will install and run a scan if it does. If not reinstall the operating system again.

Post back if you need anymore advice.

Good luck.

Your system probably has a virus. The fastest way to solve is to do a new installation of Windows. You would need a bootable CD to format and install Windows.
CAUTION: FORMATTING A HARD DRIVE WOULD ERASE ALL OF YOUR DATA. WHICH WOULD MAKE IT IRRETRIEVABLE.
For further help, please feel to ask me.

My laptop hangs when i open a progamme and see movie, my laptop is Dell vostro 1088, i installed new version of bios, but still hangs... i also format several times..how will solve this problem

You mentioned opening a program and watching a movie and it hangs, remove one stick of ram and see if there is a difference, if no! remove second stick and put back the first and test again, if this solves the problem the memory needs to be replaced.

My computer too slow always get the not responding reply.

Eliminate Viruses and Spyware
Step 1

Run your antivirus program. There may be something slowing your computer that you can remove. It is a good idea to run your antivirus program every week.
Step 2

Remove spyware. Run a good spyware tool at least twice a month.
Step 3

Use a pop-up blocker, if you have one. Check your antivirus program.


Dispose of the Extras

Step 1

Delete your document files for anything you no longer need. Saved pictures, audio and video files in particular can slow your computer.

Step 2

Remove unwanted programs from the Control Panel area. Old toolbars or games the kids downloaded off the Internet are a good place to start. Look for software you no longer use, such as the old printer you threw out last year.

Step 3

Clean out your email. Old messages are a constant drain on your computer's resources. Go through every folder, deleting everything you do not need. Leave no mail! Finish by emptying the Deleted Items folder.

Step 4

Turn off unnecessary programs. Check your taskbar for icons that show running programs. Disable anything you are not currently using.

Run Maintenance

Step 1

Run the Disk Cleanup tool located in your Control Panel. (Windows only. For other operating systems, please check the Resources section below.) This will remove temporary files, cookies and unnecessary components to speed up your computer.

Step 2

Defragment your computer. Defragging takes some time, but will speed your computer significantly. You can find the tool in your Control Panel. Run it monthly.

Step 3

Check for disk errors. Sometimes corrupted files slow down your computer. To find and fix these files, Go to My Computer and right-click on C drive. Choose Properties, then Tools.

My pc.. desktop is very slow.. its a windows vista

You may want to look into upgrading your RAM if there is less than 2GB installed. This is a recommendation that I have found in working with several PC's running this Operating System. Also, you would want to run disk clean up and remove any temporary files that Windows finds. Deleting any other temporary or unused files from your PC on a regular basis should increase system performance. In addition, if these steps do not solve your problem, you may want to consider upgrading to a faster performance hard drive (preferably a SATA II with a 32MB cache). As a last resort, you may look at your CPU to see if there is an upgrade for it, as well. Keep in mind that Vista is a resource hog and can slow down a PC within just a short period of time.

Acer Computer... extremely slow response time.

try installing ccleaner. It is free software from download.com
once installed go to the tools then to startup and disable anything running in the startup. then run cleaner. If it is still running slow change the ram. There may be some kind of driver issue with your speakers. They may also be bad speakers. Who knows' but the netbooks are not going to have the best quality of sound anyways. worst case buy headphones or external speakers

Uninstall XP Professional

If the computer was upgraded, then go into START | CONTROL PANEL | ADD/REMOVE Programs, see if uninstall Windows XP Pro is there. If it is you can uninstall it and not loose anything and the computer will reveert back to the operating system that was on there, before th upgrade.

Sometimes it is there, sometimes not.

If that doesn't work, then go to START | CONTROL PANEL | ADD/REMOVE Programs | windows components, and take out any uneeded components. Also check your system tray (bottom right by the clock) and see if there are eny programs there that you can close or better still uninstall as they eat memory and slow down your system.

Want to delete philips fun cam

Try opening task manager (control, alt, delete) and stopping this program before you delete it. Subsequently, you can go to "My Computer" or "Computer" in Vista, then to your hard drive and delete the program from there. I've done this with many hard to remove programs, including spyware.
