1). Have HP nx9500 with 512 MB memory 2). The screen is 1/2 size 3). Can I load Windows 7 and upgrade to 1 GB memory Hershall

According to the service manuals there is no memory upgrade for the 500 and standard memory is 16mb.. The 800 and 510 only have upgrade capability.

no processor upgradation this model upgradation means change MB also this is not possible

sad how, how fixya AI guessing wrong??? pathetic, mess....

HP does not support this quote
HP Media Center m1070n Desktop PC,its RETIRED now
https://support.hp.com/us-en/retired-products


The BIOS does not do that!
what HP, it has full name and model.
the MMC controls this, and is very strict. (mem-managment controller)
the memory you are buying is no good. for YOUR PC.
this is so very common
and worse every year,
ever heard of Crucial or Kingston memory
they can fit up memory for you, it very complex.
not just DMM1, 2,3, but speed, min.
density rules.
chip count rules
chip voltage, 1.3. 1.5 or both or?
Total memory max allowed and PER SOCKET !
and even number of chips per side of stick , rule.
that worst was intel i5 old processors.
those are facts, and only the exact motherboard you have a
and what processor is there, (and if mmc is external to processor that)
matter.
? this?
M1070n

finding data on such and old box.
is not easy but google can dig up bits.
why not ask Kingston? for help,.

key facts are, (besides old)
HP Media Center m1070n Desktop PC
Intel Pentium 4 520 / 2.8 GHz
Intel 915P Express (my guess, mmc is inside here)

why not find a newer box? (pc) say 2010 or newer.,
they will run better and can buy ram easy
vastly better.... even Goodwill has them for few bucks

Download and install the Windows7 Upgrade Advisor software using the following link. It will tell you what upgrades you may need.
http://windows.microsoft.com/en-US/windows/downloads/upgrade-advisor

NOTE: [These are my recommendations only] You should have a Video Card with at least 256 MB Ram to take advantage of AeroDesktop. You should have a minimum of 2 GB of System Memory.
I have a laptop with 1 GB System Ram and only 128 MB Video and Win7 works well.
