We need to read your minidumps in order to help you. Everytime you have a BSOD Windows will create a Minidump pointing to the cause.
This is how you find your minidumps with ">" meaning "left-click."
My Computer > C Drive > Windows Folder > Minidump Folder. Inside your Minidump folder are your Minidump Files. We need these files not the whole folder.
Next time you post attach these files as you would a Word document to an email. Notice in the Additonal Options screen when you reply (it is below the reply screen) the Manage Attachments. Click this on and you'll notice Browse. Click that and find your files. If you have several Zip them together and attach the Zip file by clicking Upload and when that is finished hit Submit Reply. We'll be able to open them and read them and if possible give you a solution or solutions to your issues.
