Driver for WinXP on Extensa 5620

Thank you very anyhelp in advance....

On my Acer 5620 I upgraded the Bio's and installed WinXp. From Acer website I downloaded all the driver for XP however there are 4 item still flagged with yellow explaination mark ( PCI Device, SM Bus Controller, Video Controller, and Video Controller(VGA Compatible). I downoladed these two driver from Acer website but non of them seem to work:
VGA_ATi_v8.371_XP and VGA_Intel_v 6.14.10.4820_XP.
Can anyone tell me where I can get the driver's for these items?

Thanks

 

First make sure that you installed the Intel Chipset Driver. It should really be the first thing you install, and it should get rid of the SM Bus Controller. As for the video driver, it depends on what the specs for your model are. Did you get the laptop with a discrete ATI video card or did you opt for the integrated Intel video? Whichever your system uses would be the driver you need to install. Narrow it down to one or the other, then try to troubleshoot why the correct driver isn't working. Do you get an error when trying to install the driver for the video card or does it do nothing at all?

As for the PCI Device, can't say exactly what that would be. Probably need to fix the video and chipset issue first, and see if it's still there. When all else fails, after you've run the driver installations, remove the Other devices and restart the computer to let Windows redetect them and possibly install them automatically.

 

Thank you......After installing Intel Chipset I was able to install video card.

I'm still getting yellow explanation mark on USB Root Hub under Universal Serial Bus controllers.

Can you assist?

Thanks

 

yeah well, usbhub.sys was missing under WINDOWS/system32/driver.....I downloaded usbhub.sys from driverguide and everything work fine after.....
