You could try memtest, although it would seem you have a severe RAM failure. Is it under warranty still?
I suggest you run Memtest86 for at least 8 passes.
Which one should I download?
You have two options to choose from, you can either download the ISO version then burn it do a CD and boot it from there.
The other option is downloading the auto installer for USB sticks, you then boot from that USB stick.
Be warned though, it will format your USB then install the files needed to make it bootable so any files left over will be wiped off.

So how does it work?
It works by writing a series of test patterns to most memory addresses over 9 tests, it then reads the data back to compare it for errors.
The default pass does 9 different tests varying in access patterns and test data. A tenth pass is optional from the menu which writes all the memory in zeroes then sleeps for 90 minutes and compares it to see if any address have changed, this takes 3 hours per pass each time.
My memtest86 isn't booting! What should I do?
This can be caused by a number of different reasons, common ones include your BIOS not setting using the correct settings, you might want to change your boot priority order.
Other causes include your motherboard not supporting bootable USB sticks in which case you'll need to use a CD (or floppy drive).
