10 things you can do to boost PC performance

10 things you can do to boost PC performance
Takeaway: Does your PC performance need a kick in the pants? These simple steps will help speed things up.

There’s so much information out there about PC performance (especially on Windows machines), it’s difficult to be sure what’s right and what’s not so helpful. Here are 10 proven performance enhancements you can make to your computer, many of which are free.

1: Get rid of malware

New machines shouldn’t have malware on them. But one of the most common causes of the “my PC used to be fast, and now it isn’t!” complaint is actually the presence of malware. Malware can sneak onto a computer in a zillion different ways and quite often it sits in the background slowing your machine to as it sends out spam emails, searches for other computers to infect, works on cracking cryptography, or any number of the other nefarious tasks that hackers like to use their botnet slaves for. There’s a good chance that the malware brought even more friends with it (that’s often how you see computers with thousands of viruses on them not long after the initial infection), and the infection may be bad enough to justify a wipe and reload. My first step in investigating a slow system is usually a virus scan.

2: Upgrade to a better video card

For typical business productivity tasks, a video card probably isn’t an upgrade that will have a lot of value. But for gamers and other similar uses, a video card is a slam dunk upgrade. If your current card and motherboard support SLI or CrossFireX, adding a second card and bridging them will be a good option as well. In some scenarios, better video cards can be a huge benefit even without heavy onscreen video work, because certain applications can leverage the GPUs for calculations.

3: Get a faster drive

Many times, the real performance issue is the speed of disks. Look at numbers like the RPMs, cache size, seek speed, and transfer rate to buy a faster drive. Often, a good drive will seem slow because the computer’s power settings are allowing it to spin down. You may want to consider changing these settings to make sure that the disk is more likely to be ready to work when you need it to. While the SSD vs. hard disk debate is still continuing, SSDs usually seem to feel faster to users. Boot times are usually cut for sure. But something about an SSD makes a system feel more responsive or “snappy” to use, and for day-to-day work, that’s a great feeling.

4: Address hardware and driver issues

All too often, system slowness is actually a sign of hardware problems. For example, if your CPU isn’t being properly cooled, it will often have its speed reduced in an effort to keep it from overheating. Recoverable errors with disk access can kill your throughput while not showing up as a dead drive. And bad hardware drivers can often make the whole system slow, especially video drivers. Using utilities to check your CPU speed and various temperatures, scanning for hard drive errors, and updating your drivers is a good start to investigating performance problems. Often, problems caused by hardware or drivers are not just poor speeds, but system flakiness too.

5: Use a RAID

Using a RAID can dramatically lower the read and write speeds of your disks, depending upon the RAID level you choose. You will want to do some research to see what RAID level fits your needs the best. Personally, I am a fan of RAID 1, 6, and 10 because I feel that they offer appropriate levels of data protection along with a good measure of speed improvements.

6: Try a different browser

It’s no secret: Different browsers perform differently, and most people spend a lot of time in their Web browser. Benchmarks really muddy the browser speed conversation. Some browsers perform well on some but do badly on others, even when they are supposed to test the same thing. The problem with the benchmarks is that what they usually test is not real work performance! While JavaScript is an important part of the modern Web, few Web applications beat on the JavaScript engine hard enough to produce a noticeable impact on performance. That said, it’s been my experience that the Chrome browser is the fastest for actual work. If you want to have your Web browser feel more responsive and lively, consider a switch to Chrome.

7: Remove junk

It’s easy to have a computer get loaded up with junk that slows it down. The worst part is, we invitethis garbage into our lives by installing “helpful” utilities, toolbars, and other add-ons. I could easily write a list of 10 kinds of computer-stalling junk. Here are some of the things you’ll want to seek out and remove for best performance:
  • Automatic update systems for various applications (but be careful: some apps, like Flash, Acrobat, QuickTime, and Web browsers are prime malware targets and you will want to keep these up-to-date)
  • Things that run on startup
  • Windows services you don’t really need
  • Crapware from the PC maker
  • Toolbars
  • Browser plug-ins (the Skype browser plug-in is an especially bad offender, I’ve found)
  • P2P applications
  • Web servers and database servers that were installed by since-removed applications, but left behind

8: Add a faster DNS lookup server

Most ISPs love to brag about how much bandwidth they are giving you. But they don’t mind letting the rest of their infrastructure slowly get overwhelmed or deteriorate. Among the biggest offenders are the DNS servers our ISPs use. If you want to know why things seem to take forever to start loading, slow DNS servers are often the cause. Consider adding a fast DNS server as your primary DNS server in your TCP/IP settings. Google’s Public DNS server is a great option.

9: Defrag

Defragging your hard drives is a great way to get some more performance. While modern Windows systems automatically defrag on a regular basis, I’ve found that the Windows defragging is fairly unaggressive. We’ve reviewed a lot of different defrag apps here at TechRepublic. I suggest that you check out your alternatives and find one that does a better job for you.

10: Check network connectivity

Time and time again, “system slowness” actually is caused by networking issues. Our computers do so much on the Internet that slowness there can affect just about everything you do on a regular basis. While there isn’t enough space to write an exhausting troubleshooting list here, some of the things you should try (or investigate) are:
  • Replacing the network cables, switches, routers, WiFi access points, etc.
  • Calling the ISP and checking the distance from the CO (for DSL) or the local segment’s current load (for cable); the ISP may need to rewire or rework its connectivity. Satellite customers will want to double-check their dish installation and ensure that it is tightly locked down and pointed in the right direction.
  • Malware scanning on all PCs to see if malware is burdening the network
  • Inspecting the wiring of the phone lines (for DSL) or coax (cable customers) to look for loose connections, corrosion, or flaky wires
  • Cable customers will want to find out how many splitters are between the line from the pole and their modem. If it is more than one (and preferably only a two-way splitter), they should rewire so that they have only a single two-way splitter between the pole and the modem to ensure the cleanest signal possible.

20 Windows 7 Keyboard Shortcuts You Might Not Know

20 Windows 7 Keyboard Shortcuts You Might Not Know

Mastering the keyboard will not only increase your navigation speed but it can also help with wrist fatigue. Here are some lesser known Windows shortcuts to help you become a keyboard ninja. ^_^


Global Windows Shortcuts :-

Win+1, 2, 3, 4, etc. will launch each program in your taskbar. It is helpful then to keep your most used programs at the beginning of your task bar so you can open them one right after another. This also works in Windows Vista for the quick launch icons.

Win+Alt+1, 2, 3, etc. will open the jump list for each program in the taskbar. You can then use your arrows to select which jump list option you want to open.

Win+T will cycle through taskbar programs. This is similar to just hovering over the item with your mouse but you can launch the program with Space or Enter.

Win+Home minimizes all programs except current the window. This is similar to the Aero shake and can be disabled with the same registry key.

Win+B selects the system tray which isn’t always useful but can come in very handy if your mouse stops working.

Win+Up/Down maximizes and restores down the current window so long as that window has the option to be maximized. It is exactly the same as clicking on the middle button on your windows.

Alt+Esc is like Alt+Tab but switches windows in the order they were opened and does not have the fancy window preview overlay.

Win+Pause/Break will open your system properties window. This can be helpful if you need to see the name of a computer or simple system statistics.

Ctrl+Esc can be used to open the start menu but will not work as a Windows key replacement for other shortcuts.

Ctrl+Shift+Esc will open the task manager without needing to hit Ctrl+Alt+Del first.

Alt+Space will open the window system menu which can be used to maximize (x), minimize (n), close (c), or move (m) the window which can be especially helpful if your window is somehow off-screen. This shortcut can also be helpful with windows that don’t close with the Alt+F4 shortcut such as the command window.



Windows Explorer Shortcuts :-

Here are handy shortcuts built into Windows Explorer which may have similar features in other programs too.

Alt+Up will navigate up one folder level since the up arrow on the menu bar was removed in Windows Vista. Alternatively, you can also make Backspace go up one folder level with a handy AutoHotKey script.

Shift+F10 opens the contextual or “right click” menu for a file/folder. This can be very handy for speed especially if you know which option you want to select. Look for an underlined letter in each option to know which letter you can press for faster access.



Shift+Del deletes a file without sending it to the recycle bin because who wants to empty their recycle bin anyway?

Ctrl+Shift+N creates a new folder in your current directory.

Alt+Enter opens the file properties so you can view file size, sharing settings, and creation date.



F2 renames a file or folder.

F3 will open explorer and select the search bar. If you already have an explorer window open it will highlight the search bar. In some programs it will also open the search dialog to search within that program.


F6 cycles objects in the current window. In explorer this will cycle between the location bar, options bar, left pane, and right pane. It also works with varying success in other programs.

F10 toggles the file menu in explorer.
