  My post here was precipitated by upgrading Kaspersky KIS 2013 to KIS 2014 and ending up in a state where it booted up to the logon screen but there was no keyboard available. So running a program on it will require an XP repair.I can tell you what the CPU was when it was built and it is an Intel Core 2 Duo T7200. This is off original packing slip and I have seen that T7200 in other programs, like CPUID. This link seems to indicate my CPU is Intel 64 capable and should run the 64-bit OS: [URL] the chipset "limit" of 3.25 GB independent of the video chip used? I have the Nvidia card in mine. It may also be possible that the hardware supports more than 3.25 GB but the software programs the chipset with a maximum upper limit and without a hack you can't get beyond the 3.25 GB. Thanks for these links!!! Simply awesome!!!I have Win 7 on my desktop, that's what I am on now, and prefer to have the same OS on both systems so I lean toward Win 7 Thanks! -Dennis   The T7200 will handle the 64 Bit version without problem. The upper limit of memory usage should be independent of the video card. From here on the same model: [URL] To address the "full" 4 GB, chipsets usually remap the reserved space to above the 4 GB space, so if the chipset can't do the mapping, it won't be able to access the "full" memory space Essentially the chipset can't handle more memory so you won't get the full 4 GB or more. You might get up to 3.5 GB with the NVidia card opposed to 3.25 GB with the shared Intel one but I'm not sure.
I have an Inspiron 1705 running Win XP MCE. Works great, runs Firefox, PostBox, and other apps but MS is discontinuing XP support April 2014 trying for force people to pay to upgrade to a later version of Windows.I am not sure what my options for the laptop really are. I see a 3rd party selling Win 7 Pro 64-bit SP1 (DELL) for $70. Would that work?I previously upgraded my RAM from 2GB to 4GB (I knew that under 32-bit XP I would only have about 3.2GB available but that was 50% more and worth it. If possible to run Win 7 Pro 64-bit I would expect my available RAM to be the full 4GBMy concern with any OS change is having drivers for the laptop. TIA
