I have the avg 2011 virus protection. It has new shown any viruses in the scans. Not sure what sata or ide means. I will do the hdscanWhat is the specific model of the laptop ? I will assume for now your drive is a sata and not ide ? If you are running WIN7 and booted up the ram seems normal the OS uses 900 to 1.1GB the rest is for the apps and 4GB for Win7 is fine in most cases. Download hddscan and run it and post results lets see if something is up with the WD drive. Its also possible you are infected with sypware/malware.
