Hello. Here are my computer specs.
Computer: Dell XPS Gen 5
Ghz: Intel P4 3.4 Ghz
Graphic Card: NVIDIA Geforce 6800
Ok so here is my problem. I have 1GB of RAM as you see above. Well.. My friend was going to put a 512MB stick in one of the empty slots so I would have 1.5GB, turns out they wernt the rite type for my computer. At the time my friend did not know this, so he decided to take out my computers battery and reset the BIOS or w/e. I noticed my games were getting graphical lag when they NEVER used to. Having my computer specs and all, that shouldn't happen. SO..
Someone on a different forum told me to take out the two 512MB RAM sticks I have currently in my PC, and reseat them ( plug them back in ). I did that and it worked, I had 1GB again. I installed the latest NVIDIA Driver for my GeForce 6800, rebooted my PC and checked my RAM. 512MB..
Basically, one RAM stick isn't being detected. How can I fix this? I appreciate the help. Thanks in advance.
