There is one wise saying in English: "If it isn't broken, do not repair it.". From my experience I can tell you it is a piece of real wisdom.
Ok, it is good to change video drivers from time to time, but e.g. various BIOSes are certainly things which should be left alone unless there is a *real* reason for their update ....

Isn't there anyone who can help? The BIOS was by the way necessary to upgrade because the problems that I had with my computer.

It is difficult to say what is a problem and how to solve it. I can give you just one advice: reinstall (at least VDMSound, when it does not help then the whole Windows - yes, it takes time 🙁 ) and pray and hope...
If reinstallation does not help then it is probably really something wrong with the new BIOS ...

Good news!

I managed to solve the problem. The problem was with I/0 access with NTVDM.EXE file. Bios update or some virus declined all necessary I/0 rights to the NTVDM.EXE file so it corrupted the vdmsound. If any of you gamers have this same problem, download program called Porttalk from "www.beyondlogic.org/porttalk/porttalk.htm" then copy porttalk.sys to your windows/system32/drivers directory and click on porttalk.reg file and reboot machine. Then create bat-file with following line:
(your harddrive):\(porttalk directory)\allowio ntvdm.exe 0x378

Then simply click this bat-file every time you start windows then vdmsound works perfectly! 😀
Case is sol-ved.

no. that program actually renders vdmsound completely useless, it opens up the ports to talk directly to the harwdare and bypasses the emulation. works for adlib if you have an adlib chip on an isa board, but will almost surely foobar your computer if you try to open up other sb ports or all ports and have ntvdm talk directly to hardware that only drivers are supposed to talk to. so tht .sys is EVIL.

your bios upgrade probably aded new settings to your bios menus, see what's new and potentially configurable.
