The Speedfan results do indeed show that your temperatures are too high and this would cause the system to shutdown, the results however are also missing certain details that we need so please run HWMonitor and provide a screenshot for us http://www.cpuid.com.../hwmonitor.html
Once the above is done we should have a look at your HDD storage capacity as you say in your OP "its like "working space...") 3326 MB" and we need to check if this is your HDD information.Please use the method below to take a screenshot and then upload it;
To capture and post a screenshot;
Click on the ALT key + PRT SCR key..its on the top row..right hand side..now click on start...all programs...accessories...paint....left click in the white area ...press CTRL + V...click on file...click on save...save it to your desktop...name it something related to the screen your capturing... BE SURE TO SAVE IT AS A .JPG ...otherwise it may be to big to upload... then after typing in any response you have... click on browse...desktop...find the screenshot..select it and click on the upload button...then on the lower left...after it says upload successful...click on add reply like you normally would.
Depending on the results we may need to run further software for comparison.
Go to Start
then to Run/Search
Type in compmgmt.msc
and click Enter
On the left side click on Disk Management
On the right side you will see your hard drive.
Now I need you to take a screenshot and attach it to your next reply.
