Upgraded OS and now, no sound with video or websites

The OS will ,USUALLY, apply a generic driver to the Graphics Adapter, and most essential components. Not always, but usually, when it boots the first thing you do is Windows Updates. You may have problems with some hardware when doing a OS upgrade.It can be tricky. If, say, you jump from XP to 7, you may be able to use vista drivers. Your in luck, on the ThinkPad R31 support website Vista and Win 7 drivers are available, SEE: http://support.lenovo.com/en_US/research/hints-or-tips/detail.page?&DocID=HT072387 Go with Win 7, if you have that option.

Here is a link to every driver you may need for your laptop! http://www-307.ibm.com/pc/support/site.wss/MIGR-4VGUYW.html
Here is a link to your audio driver (assuming oyur using Windows XP) http://www-307.ibm.com/pc/support/site.wss/MIGR-4VGUYW.html
No sound is most definitely a driver issue, so give me a thumbs up if these links help you!

If you have an XP COA on the bottom you can use (borrow) any XP restore disk (doesn't matter what mfg) or a standard XP disk to restore the OS. You can also buy a CD on eBay for less than $10 but you will of course need the COA.

You are apparently missing the correct drivers.

This will enable you to go to the correct website without guessing.

the new video drivers require your Thinkpad to have BIOS version 1.14 or higher so update bios or download an older ati driver.

Here's a link to IBM's video drivers. You might have to try several before finding the right one. Keep in mind that it doesn't have to have your particular model listed in order to work properly.

You don't say what OS you run, but have you tried reinstalling your audio files? This will probably fix your problem.
If you run Windows XP, 2000 or 98SE, this link will download the correct drivers :
