Maybe he doing something wrong ? We are friends and i can tell him watever you suggest. Ty in advance.
Well if the Win 7 that you have installed is the 32bit version you will only see 3.25Gb of usable memory. If you want the whole 4Gb to be seen by Windows you need the 64bit version. Not sure about the noise issue.
Well he needs to configure the RAM correctly in the Bios before anything. This means key in the correct timings/voltage and frequency. As far as the beeping goes the manual will tell you exactly what the problem is. Beeping is normally related to user error and can be adressed just by reading the codes on the manual.
He should also run memtest on each stick to make sure they are 100% good to go.... If one of the sticks has any errors then it is time for a replacemant.
