Which driver do I need for Compaq Evo D300 PC Desktop? I'm not sure it's Compaq Evo D300 PC Desktop because Aida32 just says "Compaq Evo D300". So far I've tried installing every possible title starting with "Compaq Evo D300" on www.hp.com. After rebooting my computer none of these drivers removed the yellow exclamation mark. I mean at this menu: right clicking my computer>properties>hardware>top button.

Its and HP why not post to HP.,com ? there is no COMPAQ now.
D300
no OS stated, what operating system. is it , we cant guess that ever.! and matters #1 , always.
you do know all OS are now DEAD up to and including VISTA.
right> that means all PLUG and PLAY actions are now dead
due to Microsoft cut the cord XP (for example) 3 long years ago.

at HP.,com if you looked youd see most compaqs now have zero support, its called RETIREMENT, (me , i scrap them all)
its only worth $5 used, at Goodwill stores. why waste hard earned cash on this? find one newer there for $20?
some even RAN IBM OS2, operating system gawd hope not you.,
or XP or Windows 98
why even post lacking a clear statement as to what OS.

learn rule 1 on OS.
the drivers must match your OS.
if not they fail.
there are tricks to run older drivers yes, but there is ZERO guarantees that that works.

so got HP PC, with no install disk, that be why it can work
in all cases. see why?
answer well, you can buy them now, cept from horder/scalpers online. and many of those nasty sources are all virus infected.
or worse.
most the 10 years old PC support at HP are gone
but not this one, the D310 was not deleted, dont tell HP this or its gone tomorrow.. hint , down load it all and the books while its still there. (yah)?

i guessed XP for you, why must I?

this page is 15 years old.
it dont below there but , thar see be, all fat and ugly.
XP is a virus magnet, why run that.
you will get infected, for sure. on the net. in minutes.
you cant prevent that , now.
XP has no updates, no PnP
no support
and the top reporting site in USA , only 1% of Americans use it now.

For good reasons. it's a HORROR.

XP has no base line internal protections that , started in VISTA.
VISTA is bad too but XP 100x worse.
The only OS to run if running old is W7,
period.
or as id do, run Linux, on this box, for far batter safety.
get Full blown, Ubuntu..
