sounds old, the NC , the C smacks of COMPAQ relic'izms...
let me look up what that means. 6400
yup Compaq, came with w2000, XP or VISTA
what OS on yours.???
well this old PC I think (too old really and I never liked Compaqs so )
HP PCs this year, had the F10 key , pre W7 PCs (rtm read you guide for your PC on HP.COM)
the magic F10 key loads the OS from scratch, or does repairs.
this is a BIOS hot key, that only works at power on.. just 1second after Power on press f10 , and the BIOS launches the RESTORE PARTITION IMAGE OF YOUR OS. calle HP RESTORE< but wait.
but if you kick the HP HDD out , that goes byebye, gone for ever. the install partitions gone!, bad deal that, but if HDD is dead, so be it.
it's empty , 100% ! this new HDD, id have put SSD in it.
so you have 2 choice (and sub choices)
HP covers this , if you went HP.com .
- buy the HP install disk, called the HP media kit , end story all works like new, get Vita, if you can. XP is a virus magnet.
- or buy W7 (or newer) from Microsoft.com and install that. My guess is it will be missing key drivers, for video or networking.
- Warning some old PCs have chips that have no drivers at all after VISTA, that be end of the road there.
lets say you want to put in MS W7 (its supported is why and MS does not sell the older OS, sorry they are END OF LIFE NOW)
so you are savvy and put in the DVD drive 1 , disk called
windows PE 8 live windows.
you boot it and it works but you see many chips failing,
say its Video from Nvida, and Nvida has it. good.
if its from (wild example) S3 chips sorry its dead now, and gone.
we have list of all dead video chips, its HUGE. (we love our lists, saves me ENDLESS work and searching times, wasted)
dead means maker is GONE, or does not support w7 at all.
same goes for wifi and ethernet chips
if the chip is Intel good, if not may be not.
we can talk compatibility all day,
here is your support pages, btw, after 10 years HP deletes them.
but lucky you , its on the cusp of byebye
as the first one was made in 2006/7.
here is the windows 2000 page
ill trust you can backup one page and find yours.
if your OS is missing, buy it from HP or AS THEY TELL YOU TO DO.
they do have qualified vendors that DO that.
better is go to goodwill store and pick out a PC that is 2010 and newer with W7 on it. be 100000x better that.
but who knows maybe w7 will like it.
i read the pages, it has a VAST number of chip used , for all years made,.
btw3, if you talk to HP real, and tell them your serial number
they can tell you what chips are in yours, of the the many.
is seen newer ones made in 2009 had more intel chips, all good that.
