This is an ISO file. You will need an ISO burning program to burn it. It cannot be burnt as data as it is an image.

If you use Nero there is an option called "Create Disk Image".

If you do not have Nero you can use this free program:

This will add the burning option to your right click options or shell.

With Nero just point it to the downloaded ISO. With the other recorder just right click the ISO and choose Burn Disk Image.

A new blank CD is required.

After the burn this CD will be a boot disk and will boot MemTest.

Verify that your CD drive is set to boot prior to the hard drive and boot the CD.

i think my dvd drive was causing the freezing all along. i replaced it now. working fine at the moment. re-started like 3 times to make sure.

if the problems persist i'll come back here and ask for you help again.

thanks sooo much!!!!!!!!!!
