HP Pavillion a620n update graphic card. which one?

that PC is now retired. its no longer supported. (retired says HP)
just asked for you.
i went to the advisor page and it show no support for any A620
https://support.hp.com/us-en/drivers
shows no support exists. period.
this PC is why over 10 years old
and has PATA hard drives, (long off tooth old)
and AGP slot for adding video, empty right?

there are many Net frames , not one. most PC to run may apps
need most of those not just 1 or 2. a fact.

most good apps that needs netframe ,ver.x loads it first .
facts.

WHAT that is the VIA thing.
i dug and dug and found a data sheet on a620n
hard to find it. but seems that is the ON BOARD Video chips
(GPU) used by HP, on board mother board, and jack same place.
its not a AGP slot card.
rumor has it (google)
A7V8X-LA (Kelut) mobo , 13 years old , it is.
uses, KM400a and VT8237 chips from VIA
the km400a drives the VGA jack and the AGP slot.
per this page
https://www.viatech.com/en/silicon/legacy/chipsets/km400a/

to there, click support click drivers
oops there never ways a w7 driver, for KM400
that means whom ever put w7 there, , killed the video dead.
doing that bad act.

your PC came new with what. XP ! never w7
so someone put on W7, id bet cash they did not use HP windows 7 media kit to do that, so that means the whole OS is not supported by HP, now. and for sure the card.

that leaves you with only these possibilities
1: only microsoft can help ever use device manager? and up date mode there, and be connected to the internet.?
this is 100% MS, plug and play mode , zero HP help here\
this all fails because Via never produced this drive..



2: go to VIA and get it from the chip maker.(did and fails)

4: buy new AGP card at say Newegg and make sure its w7 supported?
5: go to HP forum we are not them. and beg for your driver.

your not the first to ask.

SOLVED , there is no driver, sorry.! only XP.

Unplugged it first.Open tower. Check memory slots.Push modules down.Plug and try again.

your current integrated video card is only 64MB video memory. i suggest you upgrade to at least 128MB video memory or higher. check at your local computer store for the compatible AGP 8x video graphics card. happy shopping :)

Considering the operating system windows vista try this link below and check under graphics update the graphic card, if you have HP Integrated Digital TV Tuner and also try to upgrade the bios which is available for Microsoft Windows Vista Operating System environment.

i tought you were dead since it has an integrated graphic card, but it seems you have an expansion agp 8x slot.
you can buy a hold agp 8x graphic card for it.
anyway as a personal suggestion, don't buy a 100$ card for a pc that whose vlue would be arround 50$... buy a new cheap pc the would be enormously better than this!

its the common problem with graphic card, if its nvedia chipset graphic, there is only one temp solution, ask any hardware machanics to put a glue and heat the display ic, then it would work for a week, in that period buy the amc from hp service centre, after a week if there is a prob, company will have to replacd the motherboard

You have to check if your motherboard has a pci express or agp card slot. only then you could add a graphic card!

Posible bad power supply try using another power supply.

try enabling PCI option in the bios...
and also update your graphics card drivers for nvidia.com

It Could be a bad stick of RAM I have seen a bad stick cause all kinds of problems.
Try booting with another stick of ram and see what happens.
Good Luck
