I installed 2 EVGA GeForce GTS450 SLI cards on my SLI mobo.
I use WIN XP 2002 SP3
Quad Core Intel 2.2 mhz
EVGA 790i mobo
Had been using 2 GeForce 9800 GT cards
Video Cards previously connected with a DVI to DVI cable.
I used the 450GTS with the DVI connector for a while and had no problems.
One week after I changed the connector to a mini HDMI and when I did a restart,
windows asked for new drivers for a new PCI device.
After inserting the GTS450 CD, Windows recognized new High Definition Audio Drvers.
After using the computer for about a week, I started to hear an intermitent loud distortion on the audio.
I decided to updated the audio drivers and got the latest Microsoft High Definition Audio drivers.
Since the new drivers did not solve the distortion problem I uninstalled them.
Now I cant detect any Audio Device. First I received a messege dls.dll missing.
I installed a Creative External card and after detecting the device the first time I turned up the computer, I didnt had any sound. Now I cant detect any Audio Device at all.
When I open Audio programs I get this messages:
iTunes has detected a problem with your audio configuration.
Audio/Video playback may not operate properly.
Bad DirectSound driver. Please install proper drivers or select another device in configuration. Error Code 88780078.
Finally I did a System restore but is from a week erlier and my problem is two weeks older.
I try all the updates for the video card and for windows. Havent try a bios update yet. I tried to re-install the audio drivers and the directsound drives but Windows did not allow the updated because they are older than the ones installed.
I already did a backup of drive C: just in case I need a FORMAT.
Im planning to do a Windows restore to get all the windows original files (WIN XP SP2).
Im worried because I have some custom made programs that I need them to stay working.
Should I be able to reinstall all my programs and maintain the previous settings after doing the Windows reinstall?
I never done this but I read two guides on HOW TO DO this. They dont say if I will loose all my desktop icons and the programs funtionality.
I will appreciate any advise.
