HP pavilion dv6...or windows 7?

In all the times I have asked someone to run Seatools I have never known it not to find the hard drive, so this is a bit unusual.

The graphical lags might be due to a faulty graphics card but a faulty hard drive and several other things could cause the same problem.

Lets run a Disk Check and see what that tells us.

Disk Check

• Click on Start then type cmd in the search box. A menu will pop up with cmd at the top, right click on it and select Run as Administrator. Another box will open, at the prompt type chkdsk /r and hit Enter. Note: you must include a space between the k and the /
• You will then see the following message:
  chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)
• Type Y for yes, and hit Enter. Then reboot the computer.
• chkdsk will start when Windows begins loading again. Let all 5 phases run and don't use or turn off the computer. (The chkdsk process may take an hour or more to finish, if it appears to freeze this is normal so do not interrupt it. On drives above 500GB it can take several hours.)
• When the Disk Check is done, it will finish loading Windows.

Then follow this guide to find the chkdsk log. NOTE: You need to do the search for wininit not chkdsk.
