Top 10 Causes your computer slows

1. System Start-up packed with too many applications (Start-up overload)

Over time, as you add more and more programs to your computer, many of these applications automatically add themselves to your Windows Start-up folder. Additionally, these applications can add themselves quietly to a hidden area of your Windows Start-up system (accessed via the MSCONFIG run command). In extreme cases your PC will appear completely frozen.

Limiting the number of applications loading themselves at start-up can speed boot times considerably and increase overall system performance.

2. Spyware

Malicious programs that stealthily embed themselves into your Windows Registry and core file system are the number two most common cause of a slow PC or poor PC performance.

These applications are usually installed without your knowledge or consent during the installation of a “free” application you’re trying out, or pushed out automatically in the background when you visit websites that engage in this practice without the user’s knowledge.

These spyware programs must be removed as soon as possible to return your PC to top running speed, and before they damage your file system.

In some cases they can be removed by manually editing the Windows core file system and registry or by using an automatic spyware remover like XoftspySE, our favorite pick for spyware removal and cleaning.

3. Corrupted/Bloated Windows Registry

The Windows Registry is the master control center for your operating system and applications it runs. Corruption or overload registry issues can cause all sorts of pc performance problems, including poor application startup times, slow Windows start-up, extremely slow shut down, inability to resume from computer sleep and more.

Cleaning, compacting, and optimizing your Windows registry can go a long way to dramatically speeding up your computer’s performance, start-up and shutdown speed.

4. Badly Fragmented Hard Drive

The sixth most common reason for a slow PC is hard drive and file system fragmentation. Over time, your computer’s files can be scattered into bits and pieces located all over your hard drive. This is called fragmentation. Windows has a built in tool to help you with hard drive defragmentation:

* Open My Computer,
* Right-click once on your C: Drive and go down to “Properties”
* Select the “Tools” tab and choose the “Defragment Now” option and follow the step by step instructions.

5. Poor Security Software that is stealing system resources

Unfortunately, a large number of security software programs and suites out there demand a huge portion of your system resources and memory. This can lead to sluggish performance from the rest of your PC while your security software is constantly scanning and monitoring your computer for threats.

While threat detection is essential, some security vendors go overboard with their approach and drag your PC down with them.

To see how much memory and system resources your security software is using, press and hold CTRL+ALT+DELETE and choose the task manager.

Once the task manager is open look at the “processes” section to see how much of your system resources are being used by your security apps.

6. Remnants of uninstalled programs

Uninstalling an application either via the control panel or the application’s start menu folder has been known to leave behind remnants of the uninstalled program. These remnants can slow down your computer while Windows tries to figure out what to do with them. Additionally, residue of old program stays behind in your system registry, clogging up your PC’s core.

7. Pagefile

The Windows page file is a temporary area of memory that your computer uses to move files around while it processes functions. Basically, it’s a buffer that your computer uses for wiggle room. If your Pagefile is too small, your operating system won’t have enough room to move and you could end up with poor performance and error messages.

To increase the size of your Pagefile:

* Right-click on “My Computer” and go down to “Properties”
* Click the “Advanced” tab
* Click “Settings” under the “Performance” section
* Click the “Advanced” button
* Click “Change” under “Virtual Memory”

8. Hard Drive getting full and too many internet temp and windows temp files

If your hard drive has less than 10% free space, you will experience a dramatic slowdown in the performance of your PC. To improve this, free up some space by removing old documents you no longer use or programs that are no longer needed.

9. Virus

Closely related to Spyware, viruses can wreak havoc on your system’s performance and severely limit your PC’s ability to do what you ask it to.

Typically, viruses get onto your computer via infected email or instant messages, although they can also be installed via applications or files that you download from file-sharing networks and other non-trusted web sites.

10. Hardware Problems

The fourth most common cause of a slow or freezing computer is gradually dying internal hardware components. These can often show up in the form of slow boot and shut down, as well as poor program launches riddled with errors.

There are very few hardware diagnostic utilities out there, so we recommend careful removal of any newly installed pc components to see if they are causing a problem or incompatibility. Other than that, taking your PC to a certified, trusted hardware repair shop is usually a good idea.

Windows 7 Performance and Productivity Tips

1. Find bottlenecks

From what we’ve seen so far Windows 7 is already performing better than Vista, but if your PC seems sluggish then it’s now much easier to uncover the bottleneck. Click Start, type RESMON and press [Enter] to launch the Resource Monitor, then click the CPU, Memory, Disk or Network tabs. Windows 7 will immediately show which processes are hogging the most system resources.

The CPU view is particularly useful, and provides something like a more powerful version of Task Manager. If a program has locked up, for example, then right-click its name in the list and select Analyze Process. Windows will then try to tell you why it’s hanging – the program might be waiting for another process, perhaps – which could give you the information you need to fix the problem.

2. Keyboard shortcuts

Windows 7 supports several useful new keyboard shortcuts.

Alt+P
Display/ hide the Explorer preview pane

Windows Logo+G
Display gadgets in front of other windows

Windows Logo++ (plus key)
Zoom in, where appropriate

Windows Logo+- (minus key)
Zoom out, where appropriate

Windows Logo+Up
Maximise the current window

Windows Logo+Down
Minimise the current window

Windows Logo+Left
Snap to the left hand side of the screen

Windows Logo+Right
Snap to the right hand side of the screen

Windows Logo+Home
Minimise/ restore everything except the current window

3. Faster program launches

If you’ve launched one instance of a program but want to start another, then don’t work your way back through the Start menu. It’s much quicker to just hold down Shift and click on the program’s icon (or middle-click it), and Windows 7 will start a new instance for you.

4. Speedy video access

Want faster access to your Videos folder? Windows 7 now lets you add it to the Start menu. Just right-click the Start orb, click Properties > Start Menu > Customize, and set the Videos option to “Display as a link”. If you’ve a TV tuner that works with Windows 7 then you’ll appreciate the new option to display the Recorded TV folder on the Start menu, too.

5. Run web searches

The Windows 7 search tool can now be easily extended to search online resources, just as long as someone creates an appropriate search connector. To add Flickr support, say, visit I Started Something, click Download the Connector, choose the Open option and watch as it’s downloaded (the file is tiny, it’ll only take a moment). A “Flickr Search” option will be added to your Searches folder, and you’ll be able to search images from your desktop.

6. Schedule Media Centre downloads

You can now tell Windows Media Centre to download data at a specific time, perhaps overnight, a useful way to prevent it sapping your bandwidth for the rest of the day. Launch Media Centre, go to Tasks > Settings > General > Automatic Download Options, and set the download start and stop times that you’d like it to use.

7. Multi-threaded Robocopies

Anyone who’s ever used the excellent command-line robocopy tool will appreciate the new switches introduced with Windows 7. Our favourite, /MT, can improve speed by carrying out multi-threaded copies with the number of threads you specify (you can have up to 128, though that might be going a little too far). Enter robocopy /? at a command line for the full details.

8. Really remove the sidebar

At first glance you might think Windows 7 has got rid of the sidebar, but don’t be fooled. Gadgets are still hosted by the Sidebar.exe process, it’s just that this is now launched automatically when Windows boots. If you don’t plan on ever using gadgets then you could delete the Sidebar Registry entry at HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run, and recover a small amount of RAM. That might be a little risky, though, as we’re not quite sure what else the sidebar process does in Windows 7. The safest approach is to disable it temporarily by launching MSCONFIG.EXE, clicking the Startup tab and clearing the box next to the Startup entry. Now reboot and test Windows 7 for a day or two to confirm everything is still working, before finally deleting the sidebar Registry entry.

9. Load IE faster

Some Internet Explorer add-ons can take a while to start, dragging down the browser’s performance, but at least IE8 can now point a finger at the worst resource hogs. Click Tools > Manage Add-ons, check the Load Time in the right-hand column, and you’ll immediately see which browser extensions are slowing you down.

10. An Alt+Tab alternative

You want to access one of the five Explorer windows you have open, but there are so many other programs running that Alt+Tab makes it hard to pick out what you need. The solution? Hold down the Ctrl key while you click on the Explorer icon. Windows 7 will then cycle through the Explorer windows only, a much quicker way to locate the right one. (And of course this works with any application that has multiple windows open.)

11. Block annoying alerts

Just like Vista, Windows 7 will display a suitably stern warning if it thinks your antivirus, firewall or other security settings are incorrect.

But unlike Vista, if you disagree then you can now turn off alerts on individual topics. If you no longer want to see warnings just because you’ve dared to turn off the Windows firewall, say, then click Control Panel > System and Security > Action Centre > Change Action Centre settings, clear the Network Firewall box and click OK.

12. Parallel defrags

The standard Windows 7 defragger offers a little more control than we saw in Vista, and the command line version also has some interesting new features. The /r switch will defrag multiple drives in parallel, for instance (they’ll obviously need to be physically separate drives for this to be useful). The /h switch runs the defrag at a higher than normal priority, and the /u switch provides regular progress reports so you can see exactly what’s going on. Enter the command

defrag /c /h /u /r

in a command window to speedily defrag a system with multiple drives, or enter defrag /? to view the new options for yourself.
