10 ways to make slow computer run faster



Many people will be planning on upgrading their laptop or PC this Christmas, but here are 10 ways of avoiding a costly new purchase



Instead of consigning your old computer to the dump, here are 10 ways to make it run faster


1) Uninstall unused programs
New PCs come with a whole load of programs you will never use, and you probably don’t even know they exist.
Some programs even run background processes when you load your computer, even though you are not using them.
To remove all these pointless programs, open the Control Panel’s Programs and Features page, and have a trawl through the list of installed software. Uninstall those that you do not need, while being careful to leave programs your computer’s hardware needs (typically their publisher will be listed as the PC maker’s name or as Microsoft).
If you are still unsure about which programs to use, try a third-party called such as PC Decrapifier – it’s free for non-commercial use – which should tell you which programs you don’t want or need. 

2) Automatically delete temporary files


Temporary files amass on your computer through everyday tasks and can remain on your hard disk, slowing the computer down. Getting rid of these files, including your internet history and cookies, should give you a larger amount of hard disk space, speeding up your PC.
To do this, open “My Computer”, and select your local drive (usually C:\). Select the “Windows” folder and then open the folder titled “Temp”.
Use your mouse to right-click on the folder, and in the “View” options, choose “Details”. Once this is done, select all the files that are older than the current date and press the delete key. Then go to the Recycle Bin on your desktop and empty it. 
3) Install a solid state drive
Hard drives are the biggest cause of slow speeds and especially slow startup speeds on your PC.
While they are not cheap, installing a solid state drive, which have extremely fast read times, can speed up your startup considerably. 
4) More hard drive storage
Even if you make sure to regularly clean out all your temporarily files, if your hard drive becomes 85 per cent full, it’s going to affect your computer’s speed.
If you regularly film videos or use your PC for recording television, then you will want as big a hard drive as you can get, upwards of 1TB in size.
Here is a handy video on how to install your new hard drive.

5) Prevent unnecessary start ups
This method will primarily affect how long it takes for your laptop or PC to startup, but often many of the programs which are launched on startup continue to run and use up your computer’s memory.
To do this, click “Start” and “Run”. In “Run”, type “msconfig” and then press enter. You should then see the “Startup” tab, with all the programs ticked the ones which will load upon your computer starting up. There is a good chance the list will contain a number of programs you might not have realised were running on your computer during startup, or even at all.
You can either manually deselect those which you do not want to load, or click “Disable All” and then select those you want to run, such as particularly important programs like anti-virus software.
Another trick can be removing all the unnecessary fonts Windows loads. Windows 7 loads more than 200 fonts on startup which can slow down the speed at which it boots up. Go to the Start Menu’s search box, search for the Fonts folder and check off all the fonts you don’t need, and click the “Hide” button in the toolbar.
6) More RAM
RAM, which stands for Random Access Memory, is the temporary storage memory used by your computer and is in use when tasks are being executed by different programs. Therefore, the more programs you use, the more RAM you need, and the slower your computer will be if you don’t have enough.
A clear indicator of not having enough RAM is if your computer slows down every time you try and process large files, or it freezes will carrying out several different actions at once.
You can either add more RAM with an extra memory stick or two, or buy getting completely new memory if all the slots are taken. There is theoretically no upper limit on the amount of RAM that you can have with a 64-bit operating system, but in practical terms 4GB is more than enough for most people.
For a handy guide on what kind of RAM you need, look here, or watch the video below on how it should be installed.


You can also find out how many RAM your computer is using in the Task Manager’s Performance tab (hit Ctrl-Shift-Esc to bring this up). 
7) Run a disk defragment
Sounds complicated, but this is basically a way of reconfiguring how your hard drive stores information for maximum efficiency.
Go to “My Computer”, right-click on the hard drive and select “Properties”. Under the “Tools” tab there should be an option to “Defragment Now”.
8) Run disk clean up
Windows also includes a built-in disk de-cluttering tool called “Disk Cleanup”.
It searches through the system for unnecessary large files such as temporary Internet files, program installers, and so on.
Open Disk Cleanup by clicking “Start > All Programs > Accessories > System Tools > Disk Cleanup”. 
9) Give your computer a static IP
Another trick for speeding up your computer loading time is to give your computer a static IP address that never changes.
When you startup your computer, it spends a decent amount of time asking the network for an IP address. Not only does having a static IP address make the network easier to manage (particularly if you have several devices using the same network), but it also cuts time off your startup.
To do this, visit the “Network and Sharing Center”, and select “Change adapter settings”. Right click on your local adapter and select “Properties”. You then need to highlight what should be titled “Internet Protocoal Version 4 (TCP/IPv4), and click the properties button.
In “Use the following IP address” enter in the correct IP, Subnet mask, and Default gateway which correspond with your network setup.
Make sure to check “Validate settings upon exit” so Windows can find any problems with the addresses you entered.
To find out what your IP, subnet mask and default gateway are, go to “Start” and then “Run”, and type in “cmd”. At the command prompt, type “IPCONFIG/All” and it should come up, as shown below.

10) Hoovering out the dust
Again, this sounds a tad radical, but dust is your computer’s enemy. It can impede airflow, which is vital to keeping your computer’s temperature down, and if your computer is overheating, it is likely it will slow down its performance to cope.
(Incidentally, overheating will also make it impossible to use programs such as Skype, because for the person on the other end of the conversation it constantly sounds like an aeroplane is taking off).
If you have a desktop or a laptop, you can take off the computer’s exterior and use a hoover on a low power setting to try and remove some of the dust. Make sure your computer has been switched off for at least 30 minutes and that all cables are disconnected before starting your clean.
Use your hoover with a small attachment, and try either the reverse setting to blow air into the vents and push the dust out, or use its standard suction to try and extract some of the dust.

Engineering and Technology Rankings
Seven stars shine over Golden State

4 October 2012

The state of California has maintained its grip on the Times Higher Education engineering and technology table.

As in previous years, California, the home of the high-tech business hub Silicon Valley, takes three of the top-five places - including the number one spot, retained by the California Institute of Technology.

The Golden State takes seven of the top 50 places (two more than the UK), with an exceptional showing for the research institutions of the University of California system: Berkeley maintains fourth place; Los Angeles is seventh; Santa Barbara is 17th; San Diego comes joint 36th; and Davis follows them in 48th place.

The private Stanford University - whose nearly 90-year-old engineering school claims to have "laid the technological and business foundations for Silicon Valley" - completes California's septet, in joint fifth place. Household names such as Google, Yahoo! and Hewlett-Packard originated there.

Overall, the US dominates the list, taking almost half of the top 50 places. The country's East Coast is represented in the top 10 by Princeton University and the Massachusetts Institute of Technology.

But Asia features strongly, too. The region has 11 representatives, its best subject-level performance, led by the Republic of Korea, which has three candidates: the Pohang University of Science and Technology (24th); Seoul National University (joint 36th); and the Korea Advanced Institute of Science and Technology (44th).

Asia's highest-ranked institution is the National University of Singapore, which has risen to 12th position.

Meanwhile, Nanyang Technological University leaps from 50th to joint 26th place. Bertil Andersson, Nanyang's president, points out that the 21-year-old university is one of the world's biggest dedicated engineering universities, with two-thirds of the institution devoted to the field.

It scores particularly strongly for its engagement with industry and its international .outlook
