Re: Upgrading my computer
If you had Windows XP in the old computer that is why you only saw 2 gigs of memory. XP can only address 2 gigs. The motherboard could handle 3, 4 or possibly up to 8 gigs but the operating system couldn't. If you installed Linux, it would have used all 3 gigs.
Now, it is possible that the motherboard could only use the 2 gigs but, the manual may have been stating 2 gig max due to the limitations of XP only. If you had installed Vista you would have found out because Vista no longer had the 2 gig limitation of XP.
If you keep XP, it will never use more than 2 gigs of memory - it can't address it.
Lastly, do not keep you PC on 24/7. Turn it off at night when you go to sleep. You will burn out that Asrock motherboard in about 18 months if you leave the computer on 24/7 (or the power supply).
