HD4850 not working with Vista 64bit, Suggestions?

there is no service pack 2 for vista.....
does this happen only with vista 64bit OS. or for there OS too

check ur GPU temp and if ur card is Overclocked, then try underclocking it.
also u dint mention ur PSU. this kind of problem can be associated with bad PSU too.
another reason you might be having these problem is if u got a bad card. my old 7300GS had these kind of artifacts and withihn weeks, it died.

PSU CORSAIR|CMPSU-750TX 750W RT

I've only got vista 64bit OS. And yes its the only OS ive tried it on. I have a 9400gt card i could swap in and see if it makes a difference?

GPU is running at 40c with just firefox open. I haven't touched an OC capabilities. Everything is running as stock.

yes.....u could try out the 9400GT with the same driver.i could determine if the problem is in software or not.
also does the grafix look weird only in warhammer or for other games too.

EDIT: make sure ur PCI-e power cable is strongly attached to the card.

Graphics look disturbed just booting up. Lines vertically up and down. On the desktop i have those blue dots all over the place. My mouse cursor has two lines like this | | to the right of the mouse cursor.

Ill try swapping over the graphics card and see if that makes any difference.

if these line presents itself from the moment u boot, then i believe you should get ur card changed.
but do try out the 9400GT. and also if possible try using a different PSU.

I put the VGA 9400gt in and its 10x better. No blue dots everywhere or anything. So the HD4850 is a bad card or am i just not getting the right driver updates?

Most likely a bad card. RMA it.

RMA time, the card is defective.

RMA that badboy!

I hate when GPUs influenced by the impressionist movement gets a RMA.

They were never fully understood. They just have a different view of....stuff.

Don't feel bad, I had the same problem with EQ2, Vista 32 and an HIS 4850. I tried multiple rebuilds, all available drives and all the tricks I could fine. I even got non-fixing answers back from ATI support. All testing worked fine. Several minutes into the game I'd get the same artistic rendering that you got.

The final solution was to replace the card with a 9800GT. Everything worked fine from then on out.

I just installed a 4850 on my VISTA 64 system last week and I assure you it works fine. I'm guessing a bad card.

BTW that image looks like what was happening with my 7900GT the 4850 replaced. The 7900GT would play any game for a few minutes and then start acting up, display varying degrees of those diagonal lines.

For those who are wondering, bad GPU is the verdict. Tried the HD4850 in two different set ups with 1 OS being XP and 1 being Vista 32 bit. Gonna RMA it and wait 2 years to get it back =(

Thanks for all the help - Sinnex

You know what OP, just trade up to a 4870x2. Call it a day, and in the morning, it'll make you breakfast (its damn well hot enough to)!

Sinnex this is not addressed to you. This is to all those gurus who seem to keep repeating the same things to check!!


Who else is tired of the same stupid questions to a very common problem?

I also have the 4850 with vista64 and the card crashes with 64bit drivers specifically hd4850 drivers.
I noticed the drivers that come with the card are hd4800 drivers not hd4850. The ati website lists hd4850 drivers but they don't work with vista or work partially. I have the same screen shot that you have.

I am SICK of the incompatibility of hardware problems. The problem IS NOT the psu,the cpu,the ram,overclocking,motherboard chipset drivers,and its not a bad card. So RMA'ing that "bad boy" will only cost you time and anxiety.

I have had this card from Best buy for 3 weeks and took it back and got another from Circuit city just 2 days ago just to test for myself. And WOW the same exact driver problems!!!!!!!!

I have a new system that I built with all new parts. I am not going to list all the components as I did not have these problems until after installing the hd4850 card.........

So please don't offer a fix unless you have a fix. don't say anything about psu,cpu,chipset,ram,fan,oc,overheat,bios,etc...... these are not the problem.

And the only driver that works 70% of the time is the one that came with the card. HD4800 drivers .

So I mostlikely will take this card back and get an nvidia card. WAHHHHHHHH

Well with a 4870, that uses the same drivers as the 4850 works great under vista 64. Its a shame my 8800GTX never did(may well be fixed now).

I've been experiencing similar problems. The card works and I can use it but I can't install the drivers - the driver installation program crashes when I try and run it. I'm trying to install this on Server 2008 x64.

Although I cant help to tell you what to do. I can tell you that my 4850 works just fine with Vista 64bit. No issues at all. Nothing special either, I updated drivers from ATI website.

Hey, I am not sure where the problem was with the hd4850 but I did try one from best buy and circuit. But the problem has now corrected itself. I installed an 8800gt.

The other issue I can think of is that you may not have fully disabled the nvidia drivers. When I think about it, I had a slight issue with my 4870x2 when I first installed it. I didn't think about this until just now (thus I am posting). I uninstalled my Nvidia drivers, then shut off my PC, installed the new card, turned on the computer, installed ATi drivers, restarted and went on my way to play some games. I did notice games were crashing and that was odd. I went into windows boot setup and found that the Nvidia uninstaller left a few crapplets behind that start-up with windows. After I disabled them, I have had flawless gaming since.

Maybe this is to little to late for you, but others might find this helpful.


I forgot about this because this took less than 5 minutes of my life to figure out.
