This give an idea on how to optimize the system. No other magic work!!
Are you frustrated by your sluggish computer? With regular use, even the newest PC will slow down significantly. Here are some suggestions to free up PC resources and get that computer back in shape!
Instructions
Step 1 - Free up PC resources by deleting old programs: get some of that unused space back. In Windows XP go to start -> control panel -> add/remove programs. Highlight any program that you do not use and click REMOVE.
Step 2 - Free up PC resources by getting rid of adware and spyware: these two parasites threaten your privacy, expose you to unwanted advertisements and most importantly, slow down your computer. Free programs such as Spybot S&D and AdAware make it easy to remove adware and spyware. Simply install these programs, update them, run a scan and remove the intruders!
Step 3 - Free up PC resources by cleaning your start up files. These are files that run automatically as soon as you boot up your computer. Many of them are unneeded and are only taking up space! Besides removing spyware, Spybot S&D can also help you clean your start up files. With Spybot S&D running click the "tools" button on the left. Then click "system startup" on the left. Uncheck any entries that are highlighted in red, as they may be malicious files. Uncheck any entries of any color that are unwanted. Your computer will speed up as soon as you restart your computer!
Step 4 - Free up PC resources by cleaning your registry. Easy Cleaner is a program that can help you accomplish this. Make a backup of your registry before deleting registry entries.
Step 5 - Clean your junk and temporary files will also free up PC resources. You might be surprised at how many junk and temporary files your computer is storing! Programs such as CCleaner can help you delete these files quickly and easily.
Step 6 - Defrag your hard drive. Over time, files become misplaced and this can slow down your computer. Defragging puts files where they belong! In Windows XP, go to windows explorer and right click your hard drive. Scroll down and select properties. Click the tab named tools, and then click defragment now. Finally, select your hard drive and click defragment. Let your computer do the rest!
Step 7 - Reboot your computer, your PC resources are now freed up and you should notice a significant boost in speed.
Tips & Warnings
- All programs mentioned in this article can be downloaded for free at majorgeeks.com.
- Be careful when deleting files from your computer.
- Be sure to make a backup of your registry before editing it.
- These steps should be repeated from time to time to ensure that your computer continues running well.

Data recovery
Data recovery is the process of salvaging data from damaged, failed, corrupted, or inaccessible secondary storage media when it cannot be accessed normally. Often the data are being salvaged from storage media such as hard disk drives, storage tapes, CDs, DVDs, RAID, and other electronics. Recovery may be required due to physical damage to the storage device or logical damage to the file system that prevents it from being mounted by the host operating system.
The most common "data recovery" issue involves an operating system (OS) failure (typically on a single-disk, single-partition, single-OS system), where the goal is to simply copy all wanted files to another disk. This can be easily accomplished with a Live CD, most of which provide a means to 1) mount the system drive, 2) mount and backup disk or media drives, and 3) move the files from the system to the backup with a file manager or optical disc authoring software. Further, such cases can be mitigated by disk partitioning and consistently moving valuable data files to a different partition from the replaceable OS system files.
The second type involves a disk-level failure such as a compromised file system, disk partition, or a hard disk failure —in each of which the data cannot be easily read. Depending on the case, solutions involve repairing the file system, partition table or MBR, or hard disk recovery techniques ranging from software-based recovery of corrupted data to hardware replacement on a physically damaged disk. These last two typically indicate the permanent failure of the disk, thus "recovery" means sufficient repair for a one-time recovery of files.
A third type involves the process of retrieving files that have been "deleted" from a storage media, since the files are usually not erased in any way but are merely deleted from the directory listings

Processor Kinds
Kinds of Processors
Processors can broadly be divided into the categories of: CISC, RISC, hybrid, and special purpose.
Complex Instruction Set Computers (CISC) have a large instruction set, with hardware support for a wide variety of operations. In scientific, engineering, and mathematical operations with hand coded assembly language (and some business applications with hand coded assembly language), CISC processors usually perform the most work in the shortest time.
Reduced Instruction Set Computers (RISC) have a small, compact instruction set. In most business applications and in programs created by compilers from high level language source, RISC processors usually perform the most work in the shortest time.
Hybrid processors are some combination of CISC and RISC approaches, attempting to balance the advantages of each approach.
Special purpose processors are optimized to perform specific functions. Digital signal processors and various kinds of co-processors are the most common kinds of special purpose processors.
Hypothetical processors are processors that don’t exist yet (and may never exist). Sometimes these are processors in the design phase. Sometimes these are processors used for theoretical work. The most famous hypothetical processor is MIX (or 1009), a hypothetical teaching processor created by Donald E. Knuth for presenting computer algorithms in his famous series “The Art of Computer Programming” (discussed in the Basic Concepts section of Volume I, Fundamental Algorithms).
