Answer 1

As you didn't stated the full stop code or the error code,is like for others to guess what is the real problem.

Well,it could be your hardware or software.The irql error can happen with the NDIS.SYS file(which is your graphic card), if the error is caused by a network or modem card, but other hardware can also be the cause of the conflict. Because of the severity of the this kernel level problem, the error results in a blue screen or stop error. Driver errors would normally be obvious because the blue screen error lists a .SYS file.

Using the .SYS filename, you can find out which device or hardware is responsible for the error. You can then disable the hardware in the Windows Device Manager to see if the device is really the cause of the error.



In most cases the ‘irql not less or equal’ error can be solved by updating the drivers for the device causing the error. Also make sure you update your Windows and antivirus software, as some of these errors are not caused by hardware, but software problems like you are having multiboot OS.If can,delete Windows XP and keep Windows 7 will do.You can have XP mode in Windows7.



You can use the Windows device manager to uninstall any currently installed driver for the device and the reinstall the latest driver. When you reboot your PC after uninstalling the drivers, Windows will detect the new hardware, which allows you to install the latest drivers for the device.



If you do not have the drivers for the device in error, or are not comfortable in using the Windows device manager, you can also use a driver update program to find, download and update all device drivers for you. Driver update software will accurately identify your hardware, including the device in error, and automatically install the latest drivers for it. This can solve driver irql not less or equal errors.



If updating the drivers does not fix the issue, try loading the default BIOS options. This will ensure that RAM timing, FSB timing, and CPU timing are not causing the error. Further you can check the resource assignments on the devices in the Windows Device Manager to check if there is an irq conflict.

Answer 2

Blue screen errors, or blue screen of death (BSOD) errors, are the most severe errors Windows can encounter. Since Windows can not recover from this kernel level error, a blue screen is displayed with the error details. The error details contain a STOP error code, which indicates the type of error.

There are a lot of possible causes for blue screen errors, but most of them relate to the computer hardware. The cause of a BSOD error can be a temperature problem, a timing error, a resource conflict, hardware failure, a corrupt registry, a virus or simply a device incompatibility or driver error.

In reality, the most common cause of blue screen errors is a device driver problem. Outdated, incorrect or corrupt drivers can cause the system to encounter a STOP error, resulting in the BSOD.So the easiest way to try and fix a blue screen error is to reinstall and update your system’s device drivers. This will ensure that all driver bugs are fixed and that all hardware has the correct driver. http://best-way-to-improve-pc-performance.com Scan your computer for free now!

Don't delete any windows folders. They are important and are needed for your computer to operate correctly. Crash or physical memory dumps are normal. Doesn't mean anything is wrong with your machine. I turned mine off. This is how you do it: 1. Right-click My Computer -> Properties 2. In the Advanced tab -> Startup and Recovery -> Settings button. 3. System Failure -> Write Debugging Information -> drop down list select None. 4. Click OK

Answer 5

Try this first.

Boot into safe mode, uninstall the nvidia drivers.

After you uninstall the drivers that are installed, delete its folder in C: then reboot / reinstall then reboot again.



If this does not work this may be a memory fault (either faulty RAM or faulty sockets on the board). Grab memtest and see what it reports.

The easiest and fastest way to solve this problem is to run a registry cleaner software. A registry cleaner can eliminate errors in your record. This record stores all information about the software, drivers, applications and games that are installed on your computer. And in time, it can get bad, because some obsolete entries are not deleted and can lead to what they call the "blue screen of death."By using a registry cleaner http://make-a-computer-run-better.com the blue screen error can be eradicated and increases the speed of your computer in the process. In addition, the blue screen of death will not happen if you regularly check and care for your computer system.
