Windows XP improve performance


Windows Xp

Remove unused programs

First, remove programs you don't use anymore. Programs take up space on your computer, and some run in the background without your knowledge. Removing programs you don't use can help restore your computer's performance.

Install and run antispyware software

Most programs can be removed using the Add or Remove Programs function accessible from Control Panel, but spyware programs are more stubborn. Windows Defender (a free download from Microsoft) or another antispyware program can detect and remove these programs. You should always have an antispyware program installed, because spyware might install itself on your computer without your knowledge. After you install the antispyware program, run it to detect and remove any unwanted programs
.

Free up wasted space

Removing unused programs is a great way to free up disk space, which will speed up your computer. Another way to find wasted disk space is to use the Disk Cleanup tool.

1. Click Start, and then click My Computer.
2. Right-click Local Disk, and then click Properties.
3. On the General tab, click the Disk Cleanup button. Disk Cleanup will spend a few minutes examining             your disk.
4. The Disk Cleanup dialog box will appear. Select each of the check boxes in the Files to delete list, and         then click OK.
5. When prompted, click Yes. Disk Cleanup will spend several minutes removing these files, which will             provide you with more space.
If you have more than one hard disk drive, repeat this process for each hard disk drive listed in My Computer.

Defragment your hard disk drive

When a file is fragmented, it takes longer for the computer to read it because it has to skip to different sections of the hard disk drive. Defragmentation improves your computer's performance by reorganizing your files. While fragmentation looks complicated, it's easy to defragment your computer.

1. Click Start, and then click My Computer.
2. Right-click Local Disk, and then click Properties.
3. Click the Tools tab, and then click Defragment Now.
4. The Disk Defragmenter dialog box appears. Click your hard disk drive, and then click Defragment.
5. Disk Defragmenter will work for at least several minutes, although it might take several hours. When             prompted, click Close.
If you have more than one hard disk drive, repeat this process for each hard disk drive listed, starting at step 4.

Disconnect unused network connections

The problem with network drives is that Windows XP will attempt to connect to the network drive when it starts up. If the remote computer does not respond immediately, Windows XP will wait, which will slow down your startup time. Additionally, some programs will attempt to connect to the network drive when you browse for files and folders. To reduce the problem, you can disconnect any unused drives.

1. Click Start, and then click My Computer.
2. On the Tools menu, click Disconnect Network Drive.
3. Select the network drives that you no longer need, and then click OK.

Troubleshoot video card problems



Display problems are among the most common difficulties people have when upgrading either Windows or their computers. Here are solutions to some common display problems.

Your computer's display consists of two pieces of hardware: a video card (also known as a graphics card or display adapter), which is installed inside your computer, and the video monitor, where you see all the text and graphics your programs display.Windows uses drivers to work with these hardware devices. The majority of display problems are caused by incorrect, corrupted, or missing video drivers. Hardware failure or incorrect installation make up another set of problems, and external factors can also cause video problems.

If you have just installed Windows, or have changed your video card and are experiencing problems, the most likely cause is a missing or incorrect video driver. Most video cards will come with a disk that contains drivers and other software. Before you install it, check the information that came with the video card to be sure it supports your current version of Windows. If not, go to the manufacturer's website and download the most current driver for your version of Windows. For more information on drivers, 

Download the latest display driver.

 Remove your old driver by going to "Add/Remove Programs" and selecting the driver.

 Install your new driver by following the installation setup provided to you from the download. A new driver should fix any bugs from your previous driver.

Install a fan to blow on your computer.

Reduce overheating the video card by directing a fan at your computer. Play a game with high graphics with the fan keeping the computer case and inner components cool to test your video card for overheating.

Check your power supply.

Purchase a high-quality power supply product. Video cards can be damaged if the power supply allows too few or too many volts to the machine. If the power supply is not the issue, then simply return the product.


Do physical checks

Occasionally  it's just a mechanical problem. Sometimes removing and then re seating the video card in its expansion slot  or disconnecting and reconnecting auxiliary power cables can get it to start working properly. That's especially likely to solve your problem if your computer has just been moved or you just built it and haven't gotten it to work yet.  Once you've got the video card out, take a thorough look at it. If there is a lot of dust in the heat sink then you can poke it out or blow it out with a can of compressed air. Look at the capacitors to see if they're bulging or leaking. Check the heat sinks to make sure they are snug and not wobbling around. Loosely fitting heat sinks are the cause of many overheating problems. If everything appears to be in order, then plug it back into the motherboard and make sure to reconnect any auxiliary power cables. Make sure you push the card fully into the slot.  If your slot has a latch, then make sure that it is fully latched down. That helps make sure that the card is seated properly. You'd be surprised how often a card which appears to be dead is actually just not pushed fully into the slot.

Sharing files and printers

Sharing files and printers
Prepare your PCs that are running Windows XP
Follow these steps on each of your PCs running Windows XP.
Run the Network Setup Wizard
1. Click Start, click Control Panel, and then click Network and Internet Connections.
2. Click Network Setup Wizard, and then follow the instructions on your screen.
3. On the Name your network page, type the same workgroup name used by your other PCs.
4. On the File and printer sharing page, select Turn on and printer sharing.
Note
If your network includes PCs running Windows XP, it’s important to use the same workgroup name for all of the PCs on your network. This makes it possible for PCs running different Windows operating systems to detect and access each other. Remember that the default workgroup name is not the same in all Windows operating systems.

Specify what you want to share
1. Right-click the folder that you want to share, and then click Sharing and Security.
2. If you are sharing a drive, on the Sharing tab, click If you understand the risk but still want to share the         root of the drive, click here.
3. Select the Share this folder on the network check box.
Note
To share individual files in Windows XP, either put them in a folder and share the folder, or share them using the Public folder.

Share your files and printers
Now that you’ve prepared the PCs on your network, the next step is to indicate which files, folders, and printers you want to share. Go to the PC where you store the items you want to share.
To share a file or folder
To share a file or folder, right-click it, click Sharing and Security, and then select the people or groups you want to share with. You can also assign permissions so that those people can or cannot make changes to the file or folder you shared.
To share a printer
When you first connect a printer to your PC, you have the option of sharing it. But even if you didn't choose to share it originally, you can still do it later. Here's how:
1. Click Start, and then click Printers and Faxes.
2. Right-click the printer you want to share, and then click Sharing.
3. Click Share this printer, and then click OK.

Access the shared files and folders
Now we're ready for the final step—accessing the shared files and folders. Instructions for accessing shared printers are on the following tab.
To access shared files or folders
1. Click Start, and then click My Computer.
2. Under Other places, click My Network Places.
3. Under Network Tasks, click View workgroup computers.
4. Double-click the PC you want to access, and then type your user name and password.
5. Navigate to the folder you want.

Access the shared printers
Here's how to access the printers you've shared. Instructions for accessing shared files and folders are on the previous tab.
To access shared printers
1. Click Start, and then click Printers and Faxes.
2. In the left pane, click Add a printer.
3. In the wizard that appears, click Next, and then select A network printer, or a printer attached to another computer.
4. Select Browse for a printer, and then click Next.
5. Double-click the name of the PC that the printer is attached to, select the printer you want to access, and then click Next.
6. On the dialog box that appears, click Yes, and then complete the rest of the wizard.

Type the name of the printer's network address. This will be the name of the computer and then the name of the printer. For example, if the computer on our network was called "hope" and our printer was called "hp" the network path for our printer would be: "\\hope\hp", if you are adding the printer on a Microsoft Windows XP computer you can click the Browse icon to browse your network and locate the printer. If you're unable to connect to the printer or browse and see the printer make sure you have the network rights and that any installed firewall is temporarily disabled.
