  1. I am currently using a powerspec E372 computer, the specs are below:

    PowerSpec® E372
    Processor Intel® Core™ 2 Quad Processor Q9300
    OS genuine Windows Vista® Business 64 Bit edition
    System Board Intel DP35DP
    System Memory 8GB composed of 4- 2048MB DDR2/800 DIMMS
    Hard Drive 1TB RAID 0 - (2 x 500GB SATA HDDs) 7,200 RPM
    DVD ±R/±RW Drive
    Blu-ray ROM / DVD± / ±RW Drive
    Video GeForce 8800GT PCIe 512MB
    Sound Integrated Sigmatel® 9271D 8 channel audio
    LAN Wireless LAN G/B PCI Card
    LAN Intel® Integrated Gigabit Ethernet
    Firewire TI TSB43AB22A IEEE Firewire 1394 Controller

    Over the weekend I did a clean install of Windows 7, and not until I started reinstalling programs, and getting everything back to normal I realized I installed the 32 bit 7 and not the 64 bit 7.

    It wasn't until last night where I saw RAM 8 Gb installed 3.25 usable and realized I had done the 32 bit install.

    My question is, does it make sense to install the 64 bit OS, and if so will it take a fresh install of can i just upgrade the 64 bit on top of the 32 bit like an upgrade so i don't need to reinstall everything again.

    Thanks for your help and advice

    You will have to do a fresh install of Windows 7 64-bit

    If you want to use all of your 8 gigs of RAM (I know I would ;) ) you will have to start over. Everything I have read says you can't upgrade from x86 to x64. For what its worth, I had the choice and went with the x64 version of 7 Ultimate. I say if you have a 64 bit processor why not. You were already running Vista 64 so I wouldn't think drivers would be a problem for you.
