I have recently had a custom PC put together with Vista as the OS. It has an fault which causes it to randomly restart itself. The guys in the shop are convinced it's a Vista issue and keep trying to get me to swap back to XP. However i'm concerned that Xp can only utilise 2GB of RAM despite being able to detect more. I could swear i read this somewhere. Can anyone adivse?
Vista 32 bit supports 4GB of *address space*, not RAM. The 4gb total that it can see/address will include the memory used by hardware such as graphics cards etc and this is lopped off the amount of ram it sees. I have 4gb of ram installed but vista only sees 3.1gb.This can range between 2.75GB and 3.25GB depending on your hardware requirements. As an aside,2 x 2gb sticks will give a slightly beter performance than 3 x 1GB sticks as 2 matched pairs will be accessed quicker and used more efficiently than 3 sticks of ram. Also if you are lucky enough tthat vista sees 3.25gb you will get a slight boost from that.
Just had the same problem with a new vista machine so this may be relevant. Once or twice a day from new it crashed to the blue screen then re booted.On the 4th day i sussed it. This is often caused by bad or uninstalled/corrupt drivers. It was my realtec pci card that needed a driver install due i imagine to a corrupt or wrong version installed. In control panel go to problems and solutions and it may list your prob/conflict. Mine said problem caused by realtec 810 blah blah so i went into device manager and updated the driver and no more crashes.
