this friend of mine uses this HP laptop-
http://h10025.www1.hp.com/ewfrf/wc/d...roduct=3545691
the operating system was intalled from factory, and the laptop was bought from abroad. earlier it had 4GB RAM installed. couple of days back the laptop crashed due to overheating, then he had to reinstall os to use it again. problem is, after doing that, windows is showing that the RAM is around 3.3GB. but cpu-z or bios shows it 4GB alri8. can ne1 tell why this is happening?
