Here are some of the shortcut keys which are useful while working with Microsoft Excel.

1. First, run a scandisk or checkdisk. Let Windows fix any errors.
2. Run a disk cleanup utility…this will flush your temporary internet folder, trash can, temp system files, etc.
3. Delete any garbage files or data…if possible, run a Duplicate File Finder program.
4. Run Defrag on all partitions (NOTE: run this after you have deleted all trash and excess files!)
5. Run a registry cleaner utility and delete or get rid of any orphaned entries in that registry.
6. Check your exisiting swap file for it’s size and location (*will explain location later in the post). If you have alot of ram (i.e. 1 gig and over) set this swap file to something small, like 250 mb. The reason is that this will force Windows to load more into memory, resulting in faster performance (note: some games and applications actually require a certain sized swap file so check your applications performance after making a size adjustment for any error messages.)
7. Under XP, you can tell Windows to use Classic Style on your desktop, – this will remove the neat single click and internet-style desktop but for lower end systems this will improve performance in other areas, such as gaming and multi-tasking.
8. Run msconfig and under startup and only keep the programs that are essential to load in the tray icon (and hence stay resident in memory). Uncheck anything else non-essential, like an ATI or Nvidia control panel, Quicktime utility, Real Audio, etc.
9. Upgrade drivers! Check for the latest BIOS, video, motherboard, sound, etc drivers from the manufacturers. Alot of my friends had chipsets on their motherboard that had advanced disk management capabilities or AGP port settings but the drivers weren’t loaded for them so they were never being used. A simple upgrade realized a noticeable difference. For instance, they didn’t have the latest driver for their AGP port so it was set to 1x, instead of being used at 4x!
10. (OK, so this won’t speed up your PC but it could save you alot of time and trouble later on!) After making all these improvements, make a working backup! I use Ghost, but for XP users you can also use System Restore..

Twitter Feeds is one of the new type of feed for website and bloggers which has much greater reliability, the twitter feed have almost completely rebuilt the back end over the last month and added a lot more capacity. We’re confident that this should largely solve the problems that have occasionally meant Twitterfeed hasn’t published a post on time. What’s more, this will give us a great basis for building an even stronger, faster Twitterfeed in the near future!

1 Hardware Conflict:
The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device.
For example, a scanner usually connects internally on IRQ 6. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 5. Each device will try to hog a single IRQ for itself. If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both the device at a time it has a possible to crash. This may also result to BSD (Blue screen death).
So go to * Start-Settings-Control Panel-System-Device Manager.
Often if a device has a problem a yellow ‘!’ icon appears next to its description in the Device Manager. Highlight Computer (in the Device Manager) and press Properties to see the IRQ numbers used by your computer. If the IRQ number appears twice, two devices may be using it. Sometimes a device might share an IRQ with something described as ‘IRQ holder for PCI steering’. This can be ignored. The best way to fix this problem is to remove that faulty device and reinstall it.This is the best thing to prevent from conflict.
When working inside a computer you should switch it off, unplug the mains lead and touch an unpainted metal surface to discharge any static electricity. And main thing before opening have some hardware knowledge and beware of warranty seal. Means once the warranty seal is gone then you can’t claim the warranty of that product unless it expires.
2 Bad Ram
Ram (random-access memory) problems might bring on the blue screen of death with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem. Sometimes it may mean a part is damaged and will need replacing.
But a fatal error caused by Ram might be caused by a mismatch of chips. For example if one slot contains 1GB ram with 667 MHZ and other 1 GB 386GHZ these type Ram gets conflict so please use same MHZ Ram which is supported by your motherboard. This will often crash the machine if the Ram is overworked.
3 BIOS settings
Every motherboard is supplied with a range of chipset settings that are decided in the factory. A common way to access these settings is to press the F2 or Del button during the first few seconds of a boot-up.
Once inside the BIOS, care should be taken. It is a good idea to write down on a piece of paper all the settings that appear on the screen. That way, if you change something and the computer becomes more unstable, which may also damage your motherboard.

Here are some computer file format which you must know basically …..
ISO:
A file that is created from an image of a CD. You can make an iso yourself with a program such as Adaptec Easy CD Creator, or you can burn an ISO file to a CD-R to create a copy of a CD.
Bin/cue files:
These are also used to create an image of a CD. Most people burn these with CdrWin or Fireburner. The .bin file contains all the data for the cd, the .cue file is just a small file in text format telling the software exactly how to burn the data onto the CD.
MP3:
Don’t know what these are? What cave have you been you living in? This is a format used to compress music files. You can create your own by encoding .wav files ripped from audio CDs. There are many free players that will play mp3s for you (see the Winamp tutorial)
Ace files:
These are used to compress/archive data. Use WinAce to decompress them, or to make your own. The normal format for ace files is to have .ace, .c01, .c01, etc.
Rar files:
Another compression/archive format. This is most commonly used on iso or bin files in order to split them up into smaller files (15 MB is the norm). Winrar and many other utilities can decompress these. Rar files are usually in the format .rar, .r01, .r02, etc. But don’t be surprised if you don’t see a .rar file. Just open up winrar and point it to .r01. You also may see them packed as .001, .002, etc. (maybe with a .rar, maybe not)
Pub:
This is an FTP that has left on anonymous access. Many are owned by large companies, so they have a lot of bandwidth. This makes it possible for one person to send files there and many people can download them at once =) These are found by scanning ranges of ips (see the FTP tutorial). Just remember, like the name says, these are public. Just because you upload something there or make directories with your name does not make it ‘your pub’. At the same time, realize that if you come across a pub with another person/groups stuff on it that it may be in use to build other pubs from – so don’t ruin it for many people by deleting stuff you find there. For more on this, go read some posts on our Bulletin Board.
Proxy:
A system that is set up to forward packets… There are many different kinds, check out the proxy tutorial for more info. Basically, a proxy server helps cover up your tracks because you connect to remote computers through the proxy. Think of it as the condom of the Internet
SFV Files/ CRC Checks:
SFV files contain information about files that they accompany. You can preform a CRC check on the files using a program such as WinSFV. This compares the information in the SFV file to the file itself. If the information doesn’t match, then the file was probably messed up in transfer somehow.. try downloading it again, from a different source if possible.
