What is your comouter make and model? If it is not a branded computer what is your motherboard make and model? In what country was the computer purchased?
I am now able to comment on the images in your Sky Drive:
1. The chkdsk report as you say reveals no problems.
2. Device Manager shows 6 problem devices. We need to resolve these errors. The previous attempt to resolve these failed as image 4 reveals.
3. Folder options seem to be correct
4. Image 4 shows that an attempt to update drivers for 4 devices failed.
5. I am unable to interpret what the Memory means. I need to carry out further research.
6. Memory test error. I cannot ever recollect seeing that message. Is it occurring during the boot process? It says that the memory test, which is part of every normal boot, cannot be carried out. Late edit: What removable mass-storage devices are or have been connected to the computer?
7. As you say no minidump file has been created.
8. The StartUp and Recovery window is not showing the selection of a Default operating system. Use the scroll to select Windows 7.
9. The Windows Security Center cannot be started. Please check the status of Services. You are interested in Remote Procedure Call (RPC) and Windows Management Instrumentation (WMI) which should both be set to Automatic and have started. These are the services the Security Center needs to be able to start.

Click on the Start button and select Control Panel, Administrative Tools, Services. Locate the required service in the list. Check that it has started and that the StartUp type is Automatic. If it is not set to Automatic right click and select Properties, General tab. There is a box after StartUp type. The options are available on a drop down by clicking on the arrow down to the right of the box. Make the change and click on Apply and OK. Restart the computer and check whether it has started.
I suggest you run a check for malware
Download and install Malwarebytes (freeware version for home users only), update definitions and run in safe mode. Disable other security software whilst you are doing scans.
Download and run SuperAntiSpyware (Free Edition)http://www.superantispyware.com/download.html
