Hi, I am using MSI U100 notebook, having intel atom and windows XP as OS. For the past few days i have a problem and that is my screen resolution is 800 by 600 and i am not able to change to 1024by 80

If this only started a few days ago why not roll your system back to a date before you started having problems?

Click Start/Programs/Accessories/System Tools/System Restore then select a Restore Point (date and time) that is before you started having problems. System Restore will not delete your data, documents, music, pictures, videos or programs (unless the program was installed after the restore point you selected).

It sounds like you may have a virus or infection that did something to your display driver, and the restore will take care of it.

Shut down

Possible corrupt operating system. The cause of corrupt operating system is Windows file corrupted or virus infected Windows.

Solution corrupt Windows files:
1. START - All Programs - Accessories - System Tools - System Recovery Options - System Restore (restore to the date when the OS is still normal)
2. START - All Programs - Accessories - System Tools - System Recovery Options - System Image Recovery (restore using a backup system that you created)

Solution files corrupted due to virus infected windows
Update anti-virus and virus scan (if the virus is detected, the primary action = repair, secondary action = quarantine). Then repair the operating system with System Restore or System Recovery Options.
If the operating system infected with virus (virus infected not long ago), the best solution is to use System Restore. Restore to a date when the windows are still normal.

My Lenovo ideapad keeps freezing ever since I bought it a month ago.

If laptop was bought a month ago, it may still be covered by store exchange policy. If so, just take it back to store for exchange. If you bought it with a credit card, it may also be covered by the credit card company for its exchange or repair. Also, if you bought an extended warranty when you did the purchase, it will cover not only repair but also replacement should repair not be possible. Finally, there is the manufacturer's warranty which typically is for one year from the date of purchase but you likely will have to ship at your expense to manufacturer's designated repair site.

If you choose to continue troubleshooting yourself, here are possible freezing causes...
1. hard disk drive has defective sectors (not likely but possible which is why there is exchange)
2. virus infection (pc usually come with a firewall and antivirus which you must activate)
3. conflict between two firewalls, two antivirus or two spyware/malware programs (suppose to only run one of each but often an antivirus program includes features like an internet security suite.)

On the 2nd Tuesday of every month, Microsoft releases a free tool to address virus infections. The tool is called Microsoft Windows Malicious Software Removal Tool. It is usually downloaded in an infected computer's hard drive but if this cannot be done, the tool can be loaded into a USB stick or thumbdrive on another computer then inserted into the infected computer's USB port to be run. Microsoft also has online tools to scan and remove malware. For more information and download go to ....

You got infected with a fake security scammer. It self has put on your pc a lot more viruses so that your system is now completely corrupted.
The only way to fix this level; of infection is to reinstall from scratch. Once the reinstall is completed, and before you put your files back, install a good antivirus like Avast, which is free for home use, all you have to do to keep it is to register it.

My acer aspire 5740 with windows 7,freezes everytime i connect to the internet.pls help asap.

If your computer or laptop freezes on a regular basis, chances are it has acquired a virus or a series of viruses.

Press "Ctrl+Alt+Delete" when your computer is frozen. This will launch a Windows Security window.

Hit "Shut on the "up" arrow beside a red button located at the bottom-right corner of your screen. Select "Restart." Wait until Windows finishes the rebooting process.

Launch your web browser and install an antivirus program. AVG, Norton, McAfee, Kaspersky are all reputable makers of antivirus software and downloads

Restart your system after you have finished installing the antivirus program.

Launch the program and run a complete virus scan. Wait until your antivirus program completes the task and detects the virus infection. Follow its prompts to remove the virus.

Run virus scans at least twice a week. This will prevent your computer from getting another virus that causes problems such as the screen freezing.

I am thinking that you may have a virus or malware that has infected your system to be getting this type of problem. Go to the following sites and download and runs these apps. in an attempt to find and clean the system.

Ruun this next program and perform a quick scan, show the results when scan is complete and delete everything it finds.

This next app is a free anti-virus that just needs you to register it once a year...that's it. install this program and when it asks to perfrom a bootup scan, answer yes, that way this program will scan your hard drive before windows actually loads, that way all files will be scanned.
