was having issues with the sound drivers on my P.C.. I use a dual boot Windows 98 SE (C:\ drive)/ XP Pro (D:\drive) ,system.
Have had loads of virus issues poping up every now and then ,though have several softwares installed for A.V,Anti-Spyware ,host guards ,active monitors ,anti key loggers ,key stroke scramblers, etc... on my system,and the resident as well as online scanners give me a clean chit ,however do have viruses /keyloggers activity poping up every now and then,and a bunch of registry errors ,every time i reboot.
Some i have a feeling it is a infected driver behind all this. In 98SE(C:) ,my network adapters don't work (so cannot update my software/A.V. programs) other then that alls well.However in Windows XP my sound doesn't work ,had got an blue screen (system crashed thereafter ) :

Download updates for Windows ® WDM driver for Realtek AC'97 (ALCXWDM.SYS)

This problem was caused by Windows ® WDM driver for Realtek AC'97 (ALCXWDM.SYS). Windows ® WDM driver for Realtek AC'97 (ALCXWDM.SYS) was created by Realtek Semiconductor Corp..
So expecting a virus , made the mistake of i shift deleting the drivers after running a search ,before uploading and verifying whether/which one was infected (by the way two versions were found ALCXWDM.SYS in D: and alcxwdm.sys in C:)
Followed the solution steps, made sure the new driver was compatible in both 98/Xp environments ,and that i had un-installed it from Xp as well as 98 before proceeding , but it keeps asking me for the same file followed by a list of others,after the system tries to complete installation after reboot.
Also ever time I load a driver installation CD my explorer hangs or doesn't read,initially thought it might
be a problem with the CD ,but tried three others with the same results.Have a Samsung DVD-R,and an ASUS CDR which work otherwise

Also graphics are exploded/minimal color dept in, Xp safe mode ,and cannot be changed.
tried running Avast boot time scan several times without any results.
