At work i am using ultimatebootcd: http://www.ultimatebootcd.com/
Just burn it to a CD and boot from it, then you've tons of good testing tools.
Memtest aint that hard. Just select it and follow the instructions
There is nothing to select though.
Nothing in either folder or .rar file that can be used to actually run the damn thing. I have put the CD in (well DVD since I didn't have any CDs) and changed the BIOS to boot from CD and it just boots straight into Windows without prompting me if I would like to boot using CD.
That was what I downloaded.
