I thought this RAM might cure a lot of my computer woes but it's caused my whole system to go down.
Ok condor...that is the KEY sentence of this entire thread and the KEY phrase is "computer woes". You never mentioned computer woes until now. This is what we need to know to hopefully help you solve this problem.
What are all the woes? When did they begin? Do they happen all the time? If they Don't happen all the time then When do they happen? What are you doing when they happen? Do you receive any error messages? If you do, what is the exact wording of these messages?
And finally, OTHER than adding the RAM and then removing it, what steps have you taken to correct things?
Give us more information about the computer...processor, hard drive size, video card, what all do you have installed on the computer and what exactly do you DO with the computer...gaming? music? photos, videos, what?
