I did try memtest yesterday after burning the iso file.
Once i put in the memtest disc, i immediately realized the issue i would face. If I put in a RAM card in the 2nd slot, i cant even boot up - all the lights come on - but as i said before, the cd tray keeps clicking and the display is blank.. So i was not even able to boot off of the disc to run memtest with one RAM card in the 2nd slot.
However, when only one RAM card was present in the 1st slot, both cards had no problem being detected and memtest ran successfully without any issues.
Thanks for your help so far.
