Black screen with cursor

Two weeks ago I had my computer left running and when I went to use it the PC had locked up and there was a strange screen which I can't recall now. I rebooted it and ever since it has been freezing up. After running it a while the flashing black screen comes on with a flashing cursor in the top left corner. I have to reboot again and everything still freezes up every couple of minutes. The mouse moves but you can't click on anything. Playing a song on media player it freezes at least three times before the song is complete. I tried going back to Last Known Good Configuration, Malwarebytes, Tweaking.com Windows Repair, Paretologic RegCure, Spybot and Microsoft Security Essentials. It is still happening. I am desperate. Nothing works. Here are my specs:

Windows 7 Ultimate

Service Pack1

Manufacturer: Biostar

Processor: AMD Athlon ™II X4 620 Processor 2.60 GHz

Installed memory: 12GB

System type: 64 bit system

I am not sure if the hard drive is crashing or malware is taking over. I have searched the internet for a cure but can't find the answer. I probably have made it worse instead of better. Please help

Hi

You might want to backup your files before doing a reformat to see whether the problem persisted.

Thanks.
