    HI! thanks for the help. The computer wouldn't let me go into safe mode or any of the safe mode commands. what I ended up doing was a memory test from a cd, and found out that my RAM was bad. So I got a couple of sticks from school (i'm a network engineering student), and now my pc is running great! But thanks for the help anyway!!

Things You Must Know To Avoid PC Crash Part 1

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 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.
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, mixing 70-nanosecond (70ns) Ram with 60ns Ram will usually force the computer to run all the Ram at the slower speed. This will often crash the machine if the Ram is overworked.
One way around this problem is to enter the BIOS settings and increase the wait state of the Ram. This can make it more stable. Another way to troubleshoot a suspected Ram problem is to rearrange the Ram chips on the motherboard, or take some of them out. Then try to repeat the circumstances that caused the crash. When handling Ram try not to touch the gold connections, as they can be easily damaged.
Parity error messages also refer to Ram. Modern Ram chips are either parity (ECC) or non parity (non-ECC). It is best not to mix the two types, as this can be a cause of trouble.
EMM386 error messages refer to memory problems but may not be connected to bad Ram. This may be due to free memory problems often linked to old Dos-based programmes.
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 delete button during the first few seconds of a boot-up.
Once inside the BIOS, great 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, you will know what settings to revert to.
A common BIOS error concerns the CAS latency. This refers to the Ram. Older EDO (extended data out) Ram has a CAS latency of 3. Newer SDRam has a CAS latency of 2. Setting the wrong figure can cause the Ram to lock up and freeze the computer's display.
Mcft Windows is better at allocating IRQ numbers than any BIOS. If possible set the IRQ numbers to Auto in the BIOS. This will allow Windows to allocate the IRQ numbers (make sure the BIOS setting for Plug and Play OS is switched to 'yes' to allow Windows to do this.).

This device cannot start. (Code 10)

Right click on my computer >> selected manage.
Click On Storage & then Disk Management
If there is no drive letter assigned
Assigned a drive letter
& then Restart the Computer

This can happen, if the USB port IRQ is shared with something else that is causing data flow delays & or address conflicts at the same IRQ
It may be preferable to use a port that is directly from the USB host controller
Sometimes if this cannot be resolved by swapping around USB connections
try using a powered active USB hub between the drive and the port.
You may still have to try different USB ports this way.
The active hub can act like a buffer & thus eliminate any delay effects from the IRQ sharing

Run Check Disk to Fix the External hard drive error code 10 on Windows 7
Reboot your PC and press F8 key continously until Menu appears in DOS mode.
Select command prompt from the list. Now in the command prompt type
chkdsk c: /f /r
(space after chkdsk & space after c: )
This may take some time. You may get an error "windows cannot check the Disk- Do you want to run on reboot"
Type Yes or Y press Enter
& then Restart the Computer \r

Hi, I have a problem with my Acer Aspire 5732Z laptop. Upon boot up, I get a blue screen saying there is an error with my computer, and the following file name appears: DRIVER_IRQL_NOT_LESS_OR_EQUAL Not...

It seems you have an IRQ conflict. You install a driver and it wants to use an IRQ which is already assigned to a different device. That's why you can start in safe mode because the drivers for your added devices are not loaded.

The computing phrase "interrupt request" (or IRQ) is used to refer to either the act of interrupting the bus lines used to signal an interrupt, or the interrupt input lines on a Programmable Interrupt Controller (PIC). The interrupt request level (IRQL) is the priority of an interrupt request.

In computing, an IRQ conflict is a once common hardware error, received when two devices were trying to use the same interrupt request (or IRQ) to signal an interrupt to the Programmable Interrupt Controller (PIC).

The PIC expects interrupt requests from only one device per line, thus more than one device sending IRQ signals along the same line will generally cause an IRQ conflict that can freeze a computer.

To view your current IRQ assignments you can open Device Manager. Click on START, click on CONTROL PANEL. Click on Performance and Maintenance. Click on System. Click on the Hardware tab. Click the DEVICE MANAGER button. Once you have Device Manager open, select VIEW from the tool-bar menu, and then click Resources by Type. Double click on Interrupt Request (IRQ). If you are experiencing problems with a newly installed/configured piece of hardware and the drivers are installed correctly, then check to see if it has its own IRQ channel.

To change an IRQ setting follow these steps:
-Right click on the device in the list (see above), and then select properties.
-Click the Resources tab.
-Remove the tick from the Use automatic settings option.
-Select a non-conflicting configuration from the pull down box.
-Click OK.

Hello annwiles,

Checking IRQ Conflict in Windows 2000 or XP:

1. Click on the Start button, and click on the Run option.
2. When the Run window opens, please type in devmgmt.msc and click OK.
3. When the Device Manager Window opens, click the View menu. Then, select Resources by Connection.
4. Expand the Interrupt Request (IRQ) category to view IRQ assignments.
5. Once you find your adapter on the list, check if the number that is assigned to it is the same as anything else on the list.
6. If your adapter is sharing an IRQ with another device, you may be having an IRQ conflict.

Resolving the IRQ Conflict:

1. Try placing the Network Adapter into different PCI slots. By doing this, the BIOS will assign the network adapter a different IRQ.
2. Disabling COM and parallel ports, or built in motherboard devices (sound chips, etc) in the BIOS may help to free up their IRQ's.

Note: Changes to the BIOS can cause major problems with your computer. If you are unsure, please contact the manufacturer of the PC for further assistance.

3. You may be able to assign IRQ's by PCI slot in the BIOS. Please contact your computer manufacturer for more information.

Open device manager. (Settings, Control Panel, System)
Expand system devices.
Open PCI Bus, then IRQ steering.
This should generally be enabled, but disable it if it isn't working for you.

When you restart the computer check the system bios (Usually "Press <del> to enter settings" to see whether you are allowing the operating system to control devices through Plug and Play. Either setting may work, but setting to Plug and Play Operating system is generally better with IRQ steering enabled. Try all combinations.

Although MS no longer supports Win98 you may find that Windows Updates still works. You should take whatever updates are available.

Start up problems

This looks like a monitor problem, as the refreshing rate is set to high. Please try boot your PC in safe mode and then change the refreshing rate for lower that the monitor currently has. To get to those setting you wll need right klick your mouse on emtpy space on the desktop -> choose the last tab-> press btutton "advanced". To start PC in safe mode power on / restart computer
  1. As soon as the BIOS has finished loading, begin tapping the F8 key on your keyboard. Continue to do so until the Windows Advanced Options menu appears. If you begin tapping the F8 key too soon, some computers display a "keyboard error" message. To resolve this, restart the computer and try again.
  2. Using the arrow keys on the keyboard, scroll to and select the Safe mode menu item, and then press Enter.
This not necceserly need to be F8 key, depend on Operatin System verion and the PC itself it also can be DEL or CTRL key.
