dedicated graphic card problem

[edanndj]

Hello everyone!

I have a HP probook 4530s and after 2 years of using the dedicated graphic card (ATI Radeon 7470) seems to have a problem. I was playing my game, which is a flash based game on chrome and suddenly the screen frozened. I am using by default the ATI graphic card because the system supports switchable graphics. So after this frozen screen i turned off my laptop and after i turned on again he don't want to pass by the welcome screen of the windows. I entered in safe mode, disabeled ati graphic card and after i restart again i was able to enter windows properly. A funny thing is that after this i reinstalled windows and the first thing was to install graphic card driver. after i hit restart my laptop frozened again in the welcome screen of the windows.

Can someone please help me with this problem?!

Thank you in advance.

Hey Edanndj,

I understand you are having an issue with HP Probook 4530 freezing.

You could try doing a system restore back to a point when it was working ok.

This document will give you some assistance.

Hi and thank you for your support. As regarding my problem with my graphic card i didn't solve nothing with system restore. I have another thing, when i go to device manager and then properties of the ati radeon 7470 it says that the device did not respont (code 10). all i suspect is that the chip from the main board is broken but i don't know how to find out for sure.

Hi Edanndj,

You could try to uninstall from the Device Manager. Then reinstall from

You could also try the HP PC Hardware Diagnostics UEFI. Download and run the software.

Hi again. I allready reinstall the operating system but the eror is still there same  frozen screen at the start of the windows. i did realyze a thing by unchecking the switchable graphics in BIOS. and now i'm running on the default graphic processor, wich is the intel r provided by the processor. i will try thow the second solution that you gave to me.

Hi again!

I made that system check and all has passed.

I also made some print screens with the some errors.

Hey Edanndj,

You could try uninstalling the drivers and reinstalling the new driver from HP support page.

To get your issue more exposure I would suggest posting it in the commercial forums since this is a commercial product. You can do this at Commercial Forums.

Thanks.

Hi,

I have got almost the same problem as OP. I am a student and I use the manual switch for integrated/dedicated GPU because some programs just don't automatically switch to dedicated even if I change the settings. So I use integrated in school and dedicated at home. Yesterday, when I came from school, I tried to switch to dedicated but only black screen appeared. So I did a restart, tried to switch it - same thing. I went to safe mode, uninstalled all video card drivers (by DriverFusion) and performed a clean install of drivers after rebooting from safe mode. Restarted the system, and now it's stuck at the loading screen (this one http://www.tech-101.com/images/7_install/windows-7-install-2.png ). When I look at the HDD diode, it is constantly flickering as it should until the screen freezes at this loading. Then it stops acting whatsoever.

I also tried to exchange HDDs (I used to have an old one in laptop until 14 days ago) and it froze too, so it's not windows thing. I performed multiple ramtests, tried every solution anyone has posted in this thread, but nothing worked.

Anybody knows what's going on? Is my dedicated GPU chip dead?

Thanks for respond

(didn't want to start a new thread, this is only 1 month old and OP has the same problem as I do)

Hi Mirean,

I saw your post and based on what you put there is does sound like the dedicated GPU chip is dead. There are hardware diagnostic tools that you can try. I have included a link below. It is for Windows 7/Vista but you will using from the boot menu. I would run the System Test – Extensive Test to check out the whole computer and under Component to the Video test.
