How do I fix Graphics and Video Card Driver problems?

Roll back to the previously installed Driver

Device Manager, an inbuilt utility in Windows, allows you to troubleshoot common driver-related errors. For instance, you may sometimes start experiencing driver related problems after you have updated it. To resolve the issue, you can roll back to a previously installed driver. To do this in Windows 7/Vista, perform the following steps:

1. - Open the Control Panel window and double-click Device Manager
2. - Double-click Display Adapters to view all devices under it
3. - Double-click the device that is causing the problem
4. - Click the Driver tab
5. - Click the Roll Back Driver button and follow the onscreen instructions

Scan your computer using a Driver Update Tool

While Windows does provide an interface through which users can fix driver-related errors, the fact is that all driver-related issues cannot be resolved efficiently via Device Manager. Another fact is that resolving driver issues manually is a tedious affair. Also, you need to be proficient with Windows to carry out such a task.
On the other hand, driver management tools present no such problems. With just a click of the mouse, a driver management program scans your entire computer, identifies all installed hardware devices, and updates drivers for the identified devices

PCG-K415B is the correct model number the label is possibly the service tage or something.

Here are the specifications of your laptop

• Intel Celeron D Processor 345 3.06GHz / 533MHz FSB
• 512MB DDR SDRAM - Low cost double memory Offer - call for details
• 40GB Hard Drive
• DVD Dual Layer Drive - To read DVDs and CDs and write CDs, DVD+, DVD- and large Dual Layer DVD
• 15.4" XGA Widescreen TFT Screen
• ATI Mobility Radeon 345M 64MB shared graphics
• Integrated wireless 802.11b/g LAN - Call for advice on Wireless networking
• Integrated 3-in-1 card reader –Memory Stick, Memory Stick Pro, Memory Stick Duo
• Operating System: Windows XP Home Edition
• Includes Sony Software Bundle

My guess is that the laptop is around 1 or 1and half year old as the celeron 3.06GHz is a relatively new processor.

go to the following website, scroll down and download mobility modder. http://www.driverheaven.net/modtool.php you will also need to download the lates catalyst software from ati don't worry that it isn't for your graphics card because mobility modder will change the files. finally follow all the instructions on the dh modder webpage where you downloaded it from and you can't go wrong. i used to have a sony vaio and i couldn't beleive how sony supports their customers after sale. they haven't and probably never will release a driver for these graphics cards. Shame on Sony!

You're ATI video card has software called VPU recovery. You can shut that off in you're display properties. Suggest you upgrade you're current display drivers. If you are running Windows XP any version, than click on the link below & download the latest driver combo for you're notebook. Creat a folder on you're desktop & save the download into that folder.
After the download is complete, open add/remove programs & uninstall the older driver software. (Do not restart you're notebook)! Install the new driver combo. Than restart you're notebook.

Cable3,

Sounds like you indeed have a problem with an audio hardware driver. Presumably the 'Audio Device on High Definition Bus' is the system detecting a device it doesn't have a driver installed for.

First question - was the sound working previously? If so, did you recently install any type of audio software not related to the sound device itself?

Please provide the exact model number of the VAIO notebook and we can point you to the correct driver and try that for starters.

Not quiet sure what you mean by its only using a fraction of your graphics card?

If you go in to device manager it will tell you what graphics card you have.

What game is it you are trying to play?

If it is lagging then it suggest that your card isnt powerfull enough to cope with the game.

Have you tried dropping the display settings in the game to see if that helps?

have you tried your power management settings?

There is no replacement for this as the graphics controller is onboard, as in built into the motherboard and not a seperate dedicated graphics card. You can try updating the driver but i would firstly go to my computer>right click>properties>hardware tab>device manager>click '+' sign on display adapters, select the adapter and right click and select uninstall. Restart pc and the graphics driver will be reinstalled. If no change, then it could be that the lcd or the back lighting is faulty and requires a qualified repairer.
