10 reasons why PCs crash U must Know

Fatal error: the system has become unstable or is busy," it says. "Enter to return to Windows or press Control-Alt-Delete to restart your computer. If you do this you will lose any unsaved information in all open applications."

You have just been struck by the Blue Screen of Death. Anyone who uses Mcft Windows will be familiar with this. What can you do? More importantly, how can you prevent it happening?

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 printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. 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 devices at the same time, a crash can happen. The way to check if your computer has a hardware conflict is through the following route:

* Start-Settings-Control Panel-System-Device Manager.

Often if a device has a problem a yellow '!' 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 the problem device and reinstall it.

Sometimes you may have to find more recent drivers on the internet to make the device function properly. A good resource is www.driverguide.com. If the device is a soundcard, or a modem, it can often be fixed by moving it to a different slot on the motherboard (be careful about opening your computer, as you may void the warranty).

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.

To be fair to Mcft, the problem with IRQ numbers is not of its making. It is a legacy problem going back to the first PC designs using the IBM 8086 chip. Initially there were only eight IRQs. Today there are 16 IRQs in a PC. It is easy to run out of them. There are plans to increase the number of IRQs in future designs.

hack passwords using USB Drive

Today I will show you how to hack Passwords using an USB Pen Drive.
As we all know, Windows stores most of the passwords which are used on a daily
basis, including instant messenger passwords such as MSN, Yahoo, AOL, Windows
messenger etc.
Along with these, Windows also stores passwords of Outlook Express, SMTP, POP,
FTP accounts and auto-complete passwords of many browsers like IE and Firefox.
There exists many tools for recovering these passswords from their stored places.
Using these tools and an USB pendrive you can create your own rootkit to hack
passwords from your friend’s/college Computer.

Need the following tools to create our rootkit:

MessenPass: Recovers the passwords of most popular Instant Messenger programs:
MSN Messenger, Windows Messenger, Yahoo Messenger, ICQ Lite 4.x/2003, AOL
Instant Messenger provided with Netscape 7, Trillian, Miranda, and GAIM.

Mail PassView: Recovers the passwords of the following email programs: Outlook
Express, Microsoft Outlook 2000 (POP3 and SMTP Accounts only), Microsoft Outlook
2002/2003 (POP3, IMAP, HTTP and SMTP Accounts), IncrediMail, Eudora, Netscape
Mail, Mozilla Thunderbird, Group Mail Free.
Mail PassView can also recover the passwords of Web-based email accounts (HotMail,
Yahoo!, Gmail), if you use the associated programs of these accounts.

How To Close Ports

So i've been looking for a while on just how to close a port on a computer. I simply
couldn't find a way. Well, i finally found it. This'll only work for windows users (unless
your unix version OS has netsh).

it's actually quite simple. here's the command for it:

netsh firewall delete portopening TCP portnumber

it's that simple. Simply go to START -> RUN -> and type in that command up there,
and it'll close it for you.
or, you can also open up command prompt (START -> RUN -> CMD) and type in "netsh"
without the quotes to get to your windows firewall settings.
\
VBS Script
set ss = createobject("wscript.shell")
set ws = wscript
dim PORT
PORT = InputBox("Enter the port you wish to close:")
ss.run "netsh.exe"
ws.sleep 1000
ss.sendkeys "firewall delete portopening TCP " & PORT
ss.sendkeys "{enter}"
ws.sleep 500
'ss.sendkeys "exit"
'ss.sendkeys "{enter}"

.BAT Script
@echo off
title Port Closer
echo Port Closer
echo.
set /p port=Type the port number you wish to close here:
netsh firewall delete portopening TCP %port%
msg /w * Port %port% has been closed.
exit
