I've just bought a new custom built PC and it has a problem. It's abruptly restarts itself randomly and though it has 2 x 2GB RAM cards in it only just over 3.3GB of RAM is showing under properties. Would you think i have a duff RAM card that's causing the restarts? The restarts happen randomly regardless of what programs are running or indeed if no programs are running.
4GB same as Windows XP Suggest you contact the retailer as you have only just bought the PC.
If you can open the case without voiding your warranty, then you could check that the ram sticks are firmly in place in their slots and are being recognised. Take them both out and then put one back and boot up. Check in properties if it is 1GB Switch off pc. Do same with other ram stick (using the same slot)
Now do it with both ram sticks in.
note: the slot nearest the CPU is (usually) slot one.

Just a thought, if some of your other components have inbuilt memory (graphics card for example) then that would cause some of the ram stick to be not recognised as it would take it over the 4 GB that can be seen by Vista/XP
