[Closed] Computer rebooting/locking up a lot

Pretty much the pc freezes when opening the programs section of the start menu. It also freezes sometimes when right clicking files or when opening new firefox tabs. The computer will reboot seemingly at random several times a day. AVG isnt picking up any virus or malware…

Here is the log.

Hi and Welcome,

Please do the following:

STEP #1

Please download DDS and save it to your desktop.

Disable any script blocking protection
Double click dds.pif to run the tool.
When done, two DDS.txt's will open.
Save both reports to your desktop.

—————————————————
Please include the contents of the following in your next reply:

DDS.txt
Attach.txt.

STEP #2

Download the GMER Rootkit Scanner. Unzip it to your Desktop.
Before scanning, make sure all other running programs are closed and no other actions like a scheduled antivirus scan will occur while the scan is being performed. Do not use your computer for anything else during the scan.
Double-click gmer.exe. The program will begin to run.
**Caution**
These types of scans can produce false positives. Do NOT take any action on any "<— ROOKIT" entries unless advised!
If possible rootkit activity is found, you will be asked if you would like to perform a full scan.

Click NO
In the right panel, you will see a bunch of boxes that have been checked … leave everything checked and ensure the Show all box is un-checked.
Now click the Scan button.
Once the scan is complete, you may receive another notice about rootkit activity.
Click OK.
GMER will produce a log. Click on the [Save..] button, and in the File name area, type in "GMER.txt"
Save it where you can easily find it, such as your desktop.

Post the contents of GMER.txt in your next reply.

Please describe how your computer is behaving at the moment, listing any symptoms and problems that you are experiencing.
