In order to take a better look at what is going on with your system, please do the following:

Download DDS from one of these locations:

Save to the Desktop.

Right-click DDS and select: Run as Administrator

When done, DDS opens two logs:
-DDS.txt (Opens on the Desktop)
-Attach.txt (Is minimized - will show on the TaskBar)

Save both reports to your Desktop.

Since this report can be quite large, please go to the ‘Uploading’ website:

In: Select files to upload, click 'Browse', and 'Look in' the Desktop.
Select the DDS.txt report, and click on 'Open'
You will see the following:
“Your file has been uploaded successfully: (Name and size of the file)”

Please copy the 'Download link', and provide it in your reply.

Do the same with the Attach.txt.

Also download aswMBR:

Save it to the Desktop.

Right-click the file and select: Run as Administrator

Click 'Scan'

Upon completion of the scan, click ‘Save log’ and save it to the Desktop.
Note - Please do NOT attempt any fix anything!!

Also post the log produced by 'aswMBR' in your reply.

You will notice that another file is created on the Desktop.
It is named MBR.dat.

Please keep the file on the Desktop, and do not do anything with it.
This is important, just in case we need to have access to the Master Boot Record (MBR) information.
