Last week my friend Pwajdeur was over, and I gave him my copy of Hiren's BootCD. I did not realize how useful that CD is, so tonight I had to go back online and get the newest version and burn another copy for myself.
This CD has everything you need to find out what's wrong with your busted computer. In short order, Pwajdeur and I were able to find out that the memory on his system was toast.
