You have other things to consider besides wattage. Find the entire list of requirements for power for your laptop, probably on the company website (you can look up the model number in their search option under support). Make sure your power supply matches all the specs or you will burn the motherboard up.
In Windows, go to Computer or My Computer and right-click on the drive that you wish to defrag. On the context menu, select Properties. Then tab over to Tools and select defragment. If you run into trouble, then scan the drive for errors. That is found in the same place where you load Defrag. If you still have trouble, then scan and defragment in Safe Mode.
Or you can install a program such as Defraggler from Piriform and use it to defrag the hard drive.
Yes. This is known as "formatting" the drive. If you don't have a DOS-based disk management utility, you can quickly do this by booting to a Windows installation CD - most provide an option to format the drive and assign partitions before you install the operating system, and you can simply format the drive and cancel the install.
Is this a riddle? Here's what I would do...find another fiance. You aren't tied to him or his problems, and you will never change him. Only he can change himself, and he has to desire to do that. Good luck.
The CPU, or Central Processing Unit performs the calculations and logic functions of the computer. CPU's only perform the most basic of functions, such as adding the contents of a memory location to the contents of a CPU "register", or comparing the contents of one register to the contents of another register and "jump" on a specified condition such as "equal to", "greater than" or "less than". CPU's are also able to initiate transfer of large blocks of data, read or write data to/from peripheral devices, and in general, watch over system functions. Of course, this is an oversimplification of the power and function of the CPU, but it gives you an idea of what is going on. CPU's have the capacity to perform many low level functions that are enhanced when added together into an application. If done correctly, the entire process is transparent to the user and all you see is a well designed application. The heatsink and the cpu needs a fan to cool them off
