ATI HD4850 Windows 7 Driver problem w/no display

[Ottomania]

I have old Ati Radeon 4850 1G used clean.

A few days ago my friend closed pc after playin CS:GO on Steam. Next day I came home and mom told me no display. I plugged it onboard VGA slot and I have display.

Before this incident I had updated my driver via autodetection utility of AMD. But no problem occured for 2-3 days.

Now, deleted drivers and tried to install Legacy. But it's for 2k 3k 4k etc. graphic cards. And it installs 2100 WDDM driver.

No display.

HELP!

Like my name? Because it actually happened! lol

The old ATI HD48XX were great cards! I loved them!
Same thing happened to my 4870x2.
I updated my drivers and a few days after the card stopped working.
Never figured out exactly what it was.
+The card booted in the PC
+No PC error beeps
+Fans worked
- no post, no display
took it out and some of the plastic had actually melted!

If your not getting post...
unplug your PC and remove the MB battery then hold down the power button to reset the BIOS. If still no post then your card might be dead or the power supply might not be able to power the card anymore. Believe it or not they do go bad just enough not to power discrete cars sometimes... go fig?

If you can post but just no video when windows boots up...
Unplug your video card. boot with on board graphics. Uninstall CC and any other amd/ati video card tools. search for your ATI or AMD graphics drivers and manually delete them. shut down and reinstall your card and see if windows will boot using plug and play drivers. If so, your card is still good, if not, it's toast.

Card is OK I think. When I replugged the card Windows get it. There's icon in device manager. This time I tried auto update choosing one of the 4800s on the list. It didn't worked. After that tried full auto update it installed standard VGA driver (FTW?).


But automatically updates or CCC drivers didn't make it work. Auto detect says I use 2100, which obviously not.

I though the MB battery and some BIOS stuff. But I think it's about new drivers and CCC are not compatible with 4850. idk. HEELP! 😀

Edit: When I installed one of the 4800 drivers on the list it came up with code 43.

Windows is not recognizing the video card.
Unfortunately you can't beat windows over the head until it stops being a ars so your going to have to manually point to the drivers.
Device Manager > Select the hardware > properties > update drivers > browse my computer > select the location where you extracted the drivers
or something like that.
unfortunately I've ran into a lot of hardware in recent years that keep their drivers packed into installers and won't extract if an error occurs during installation. but I believe that AMD still extracts drivers to you C: directory before it tries to install.

Legacy 13.9 installs CCC. It's for 2k 3k 4k Radeon graphics cards which can be found here: ( http://support.amd.com/en-us/download/desktop/legacy?product=legacy2&os=Windows%207%20-%2032 )

But even no 4k drivers, even not signed ones. There's 5k 6k 7k even 8k drivers. Now I wiped up everything. Redownloading and reinstalling. HELP!

Edit: Redownloaded and installed. True signed drivers of 4850 found and installed. But, Windows has stopped this device bla bla (Code 43)... There're several topic about 43. I've applied them. Usb value on regedit 3 etc. Nothing changed. 4850 driver installed but code 43 came up. HELP! 😀

I plugged another card (Radeon HD 4850 Sapphire OC Edition 512mb) it didn't work. So I think it's now the hardware. HELP!

Sorry for the long wait. I am unavailable over the weekends.
To solve code 43 you must go to your device manager, find the problem hardware, right click and select scan for hardware changes.
Or you may have to select it, uninstall then scan for hardware changes.
If it works the problem should go away, if it does not you need to go into the properties and to see if the device is using the drivers you want.
It may not be a hardware issue, it could be that the drivers you hare are not signed so your computer wants to use other drivers it thinks are correct but are causing an error.

Try running your computer with linux from a DVD with your card plugged in.
If your card runs fine under linux then it might be a windows problem.
You may need to disable your on board graphics in your bios but with how fritzy the situation is that might be a bad idea.
Worst case your hardware may be bad but it is more likely it is something that has gone wrong in windows.
If you can't resolve your problem and your absolutely set on keeping your old hardware you may have to resort to reinstalling windows.
