Can you be more explicit on what happens (and what you can do and what you can not do) if you boot. It's not clear from your current description, I'm afraid. And please tell your OS.
Maybe your computer has been fine, but somehow it isn't any more. But it ain't clear yet what's wrong with it.
The risk of not doing a regular backup of things you don't want to lose (like your photo's) is that you will lose them if you can't do a last-minute backup. Of course, it is - or has been - your choice to not do it, so don't blame me if they get lost now. But I don't think they will. Wiping a disk is hardly ever necessary. And - unless it's severely broken - it's possible to buy a new hard disk, install the OS on it, then copy the contents of the old disk to it. But even that might be unnecessary.
I purchased a PC 2 months ago,it had been running fine until now. I cannot access anything on my C drive, the computer freezes and then the screen blacks out for a few seconds i then have to restart for it to work again? But if i try to access my computer nothing happens, I cannot access any programs on my c drive,i cannot even connect to the internet but have been told my connection is fine! What can i do? I have been told i will have to wipe my PC, I cannot even save all my family pics to disk on my computer? Is there any way i can save my photos?
