win32k.sys BSOD error. PLEASE HELP!!!

Hi,
I have windows xp and recently have been getting this bsod. There is no particular thing that I do that causes it. Attached is a picture of the blue screen.

 

May I suggest you download the latest version of Malwarebytes. 2.0.2.1012

After updating, click the scan tab at the top and select Custom. Then Scan Now, then select the options as shown in this box.

It takes a bit of time but is worth it.

 

You should also run checkdisk with the /r parameter:

How to perform checkdisk

if you do not have Recovery Console installed, then run from the start menu

go to start, run, type in cmd

in cmd type in chkdsk c: /r and press enter

type Y for yes and press enter

type exit and press enter

restart pc, allow checkdisk to finish and run again

this is a lengthy process depending on the size of your harddrive, the percentages will fluctuate, this is normal, you can view report in the event viewer.
go to start>run> and type in eventvwr.msc, click on the applications directory, and in the right hand panel choose winlogon.
