stop: 0x000000124 and stop: c0000135 BSoD Windows 7 and vista

Hi, this is an error that can have a few causes but as a general rule of thumb it is usually hardware. There are TS steps you can do, and I'll give you the list, it is pretty comprehensive but if you follow them we will definitely get you closer to a solution.

If it is software  In a lot of cases it is a corrupted driver or a driver conflict.  The most common causes of blue screens are over heating, bad RAM, and  video card problems.  Make sure you have a good temperature and voltage monitoring program, keep your fans cleaned out, check your drivers to make sure they are all up to date, and try a clean boot to rule out driver conflicts… another summary follows:

A crash can be caused by a number of things, including:

·         An outdated or misbehaving device driver,

·         A computer virus,

·         A corrupted program, or

·         A problem with your computer's memory.

·         Hard disk  or motherboard is corrupted

I would suggest you to try the following steps:

Step 1: Try to boot the computer in safe mode and check if the issue persists:

 a. Restart your computer and start pressing the F8 key on your keyboard. On a computer that is configured for booting to multiple operating systems, you can press the F8 key when the Boot Menu appears.

b. Select an option when the Windows Advanced Options menu appears, and then press ENTER.

c. When the Boot menu appears again, and the words "safe mode” appear at the bottom, select the installation that you want to start, and then press ENTER.

If the computer works fine in safe mode, you can infer that some third party software is causing the issue.

Step 2: Put the computer in clean boot (to figure out if any third party software is hindering the process)

Perform a clean boot (check step 1 of the link); if everything works fine after a clean boot, you can infer that some third party services are causing the problem.

Proceed with the remaining steps to pin-point out the third party service.

Note: After you figure out the problem causing program, you may have to update or install a higher version of the program, if you seldom use that software you can consider uninstalling

Important: - remember to put the computer back to normal startup follow step 7 in the link.

 If the issue persists,

Step 3: Try to install the latest drivers for all the devices via windows update or check the device manufacturer’s website.

1.         Open Windows Update by clicking the Start button, clicking All Programs, and then clicking Windows Update.

2.         In the left pane, click Check for updates.

Install all the important and recommended updates.

Step 4: Check if RAM sticks are working fine; follow the steps mentioned in the link below

Step 5: Check your hard disk for errors; follow the steps mentioned in the link below

Step 7: You may consider flashing\updating the BIOS (Basic input output system)

Modifying BIOS/complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.

Please check with your computer manufacturer for flashing the BIOS. 

Hope this helps,
