Niotic,
You've not told us anything about your computer, like brand, model, age, OS, amount of ram, etc.
And most importantly, why do you think you have bad ram?
What's going on with your computer?
Explain in as much detail as you can.
Do you have a floppy disk drive? Making a boot disk for Memtest on a floppy is the easiest way to run it.
Fill in the blanks, so we can better advise you.
Cheers mate!
