I have had it since September. Never had any problems with it, until today. The screen got slammed shut and now will not do anything. It gets stuck on the starting windows screen and goes black. I have tried F11 and it does nothing. I have tried rebooting it but it just goes black and 15 minutes later it goes to a grey screen and has the cursor, but won't do anything else! I need help, please.

Which operating system you have installed? because there might be problem with the boot files, They may corrupted and unable to boot. Once check BIOS as well, check the boot devices list in that check first boot device should be set to hard disk, if not do it and press F10 and save the settings. Make sure that you have loaded operating system. One more reason behind this is your system is infected with viruses, get a good internet security software and scan the whole system.

If you are sure that you have loaded operating system, insert the operating system CD and boot from that cd. At the first screen you will find the options to repair the boot, try to repair it. If not done go to the next step where you will asked to check the license agreement press F8. After it will check for the OS if any previous versions are installed if not it will show you the list. Try to repair. If this screen is not shown, main problem with the file system. In some situations many os lost the File system, I have faced the problem so many times. If you lost the file system you cannot recover the data. If same thing happens to you, you need to delete the partition and create it. Install the OS and follow the procedure.

If you have any data that you lost, download the recover my files software and try to get your data back. It is a good software I assure you it recovers your data.

I wanted to clean up the disk so I scheduled a boot-time scan from Avast Antivirus. Normally, my files stay secured after boot-time scanning, but for some reason, I lost some documents and completely wiped out by virus. It's fresh and all, but the problem is that hardware resets to its original position every time, When I restarting the laptop. While it was rebooting, I deleted all the viruses infected and wonder if this has to do anything with this issue.

How do stop my laptop from re-rebooting every single time! Please help me. This is really annoying.

Avast is a good antivirus programmes that detects threats if you have a Full version of software. Avast providing the free version of it's antivirus programme with 1 year license, but you need to know why. The free version of Avast has limited features. If you install it detects threats up to the signature's level. Better Buy the full version to enjoy all the features.

Already you have scheduled boot time scan, It scans boot files...if any threat found it cleans and restarts your computer. Better Install a full version of internet security and update the virus definitions, scan the whole computer. Before scanning the system, disconnect your PC from the Internet.

If the problem persists, you need to repair the windows using windows installation disc, may be the boot files are infected, again the PC is re-restarting because of the it restoring the files from Backup, after restoring PC can able to boot.

Internet Security or All in One security has many features like anti Malware, antivirus  anti root-kit  firewall, anti trojan....etc. 

If your files are deleted unknowingly you can recover, there are many software's available on Internet, download them, they provide trial versions if you can afford buy the full version.
