Windows 7: c: Health (Boot, Page File, Active, Crash Dump, Primary Partition)

Can anyone help me with my problem please

Why yes I can!

If you want to communicate with others over the web it is important to understand that the other people cannot read your mind, so you want to carefully consider what your question is, clearly and concisely, and ask it with as much description and detail as you can. This way the observer can "see" what the problem is as well as you can!

Hope that helps!

PS: see that 101MB unallocated space in your screenshot? Leave that alone. Windows requires that space at the beginning and end of some drives to use for some advanced features, like dual booting and the creation of Dynamic Disks.

can you make some step by step on how to fix my problem please..

What is your problem?

on how to fix my problem.. you mean i need to install win xp and win 7.. that's dual booting right

No!
You do not need to dual boot unless you want to!

Could you please explain what it is you want to fix?
I can't see anything wrong in the screenshot you posted.

when im playing or using my pc in 15 minutes.. somethings pop-ups that something error on my hard disk.. and asking me to back up my files... and when i tried to re-install win-7 and make some partitions.. there are 2 unlocated partitions and i can delete it.. and why in my screen is it's disk 0

Could be a failing hard disk. Find out your hard drive's maker and model and download the diagnostic utilities from their site. This tutorial tells you what to do to find out what hard drive you have (among other things).

As for the "disk 0", that's normal. Machines start to count with 0, not with 1 like humans do. So if you have 3 devices, for a machine you will have "device 0", "device 1" and "device 2".

Please run CheckDisk on your drive:

• Start > All Programs > Accessories
• Right click on Command Prompt > click "Run As Administrator"
• In the window that opens > type: chkdsk C: /f > press ENTER
• You will be warned that chkdsk cannot run unless you restart > Restart
• Let checkdisk run without interuption, do not disturb the process > Windows will load when it is done

Look for any errors in the list as it runs, if any, and make note of them.
