Hey guys I have a Compaq Presario SR1365CL-B with AMD Athlon(64) XP 3300+ 2.4 GHz the pc came with pc 3200 512 mb ram. I upgraded the ram to 2gb the max it can handle. I fired the pc up and everything took, but now i cant use my dvd burners. I went to my device manager and there was a yellow exclamation point on the 2 drives i have installed in my system. I went to the properties of those drives and it said i had a code 41 and windows successfully loaded the device drivers but cant find the device. So did the installation of the new memory mess the dvd drives up? I need some advice. The droves were working like 3 days ago when we last used them.
