Basically, i built my own rig a week ago and had nothing but BSOD's, after endless testing and reformatting vista i found that it was ONE of the 2 ram sticks (totalling 2gb) was fubar. So i took that one out and my rig now works fine with just one of them in...but its a certain one, not any one. I then put the other stick in by itself and found i got a BSOD again. BUT the issue here is, If i put BOTH in (in same slots which HAVE been tested) that i can boot up into safe mode and do anything there but in normal mode it just blurts out the BSOD! and bare in mind i have done ramtests with no issues. Reformatting wont do anything as i already have...any suggestions? Iv had loads before and im used to fixing them but this is really mind bending! Thank you ever so much!
