Re: Help with Q9550 and Vista 64
For your second question, try a program called siw, just do a search on google! It can tell you all your pc specs dealing with your motherboard, graphics, ram, hard drive, processor, etc.! How much ram do you have? 32 bit of xp will only use 3.5gb of ram or less, so if you have a 4gb ram or better, use 64 bit of xp or vista 64 bit!
Don't re-format if you have stuff on your hard drive, unless you don't care if you delete it!
