I am no computer expert whiz-kid but I think it is almost impossible to restore the factory settings once a computer has been in service for a time as every time it is used it gathers rubbish - temporary files, cookies, empty folders and things that constantly go on behind the scenes. There are also extra programmes, software and documents that gather in all sorts of places, each slightly affecting how the computer works and responds and virtually impossible to get rid of and if you do get rid of some of them there is often a driver missing from either the operating system or one of the accessories.
The only way to get it back to the way it was when new would be to format the hard drive and reload the operating system.
Having lines on your webcam might be a hardware related issue.
However, before we come to that conclusion; you may also try installing the webcam driver.
If you need any help related to the webcam driver installation, please provide me the below details:
1) Make and model of the Laptop.
2) Operating system installed in the computer.
The correct term is to "flash the BIOS". The BIOS (Basic Input-Output System" is a small, physical chip hardwired onto every computer motherboard. It is key to booting and running your computer; when you press the power button, the power supply starts and the very next thing that activates is the BIOS which sends instructions to the CPU (your processor) to activate your hard drive and other devices (DVD drives, USB ports, etc.) which has your operating system (aka Windows) and boots Windows. Sometimes you have new technology you want to install on an old machine, and in order for your operating system to "see" it the BIOS must be updated with new commands. So "flashing" means that you overwrite the BIOS with a new set of instructions. No BIOS should be flashed unless: >You absolutely need to >You know exactly what you are doing and how to do it >You know exactly what to do if your flash goes bad. If a flash is done improperly you will ruin your computer and cannot boot. Period. Sometimes it can be fixed with a re-flash, but don't depend on it.
I always use the advanced setting when installing software from these types of website. It should then give you the options of not downloading the toolbars etc. Also create a folder in you computer drive that you can save these software too. In your case name it "SearchEX". This makes it easy to remove should you need to.
you need to use the recovery disc that came with laptop back up all important files first to either external hard drive or usb drive then restart computer press F12 on your computer put recovery cd in dvd drive then select boot from cd in the list that comes up when you press F12 when disc loads choose factory restore option.if you haven't got the recovery cd then you need to get your hands on a copy of windows some good deals on ebay at moment
You're running too much at the same time. I would not recommend touching the settings unless you are positive that you know what you are doing.
However, if you are confident that you know what you are doing, and you want to take matters into your own hands:
Under Performance, click settings,
go to the Advanced tab, and set more virtual memory
