Looks like Windows XP?
If this is Windows XP..
You may have run out of room on your disk,
Device driver or system file may be damaged (If one of these happened, there is practically no way to fix that unless you have a Windows XP disk. Unfortunately, I do not know much about the Windows XP setup.)
Try removing any devices, disks, anything attached to your computer.
If not, spam the F8 key right when you start your computer, and disable driver signiture.
If none of this works, I would recommend taking it somewhere to get your files backed up. If you do have Windows XP, I recommend getting a Windows 8 computer.
Hope this helps.
Also, do you mind uploading the image somewhere (photo bucket) and giving me the link so i can see it?
