I tried to install a Just Link CD R-RW drive from an old computer into this one without success. I tried some different things to get it to work, but still no go. I removed the drive and left the computer as it was. After that, the computer would boot up normally.
Also, I installed a Sound Blaster Audigy card on this computer as well. There was a problem with that installation when my Avast Antivirus found a trojan in the installation software (CD). I posted that issue on this forum under Operating System - Windows XP. Despite that, I was able to successfully install Sound Blaster. It is working just fine as I type up this post.
After installing the sound card and software, I wanted to get into my device manager to see if the onboard sound had been disabled and/or drivers uninstalled. At one point during the Sound Blaster installation, the software detected another sound card on the system and indicated it was not a good idea to run multiple sounds cards simultaneously. I exited the installation at that time and went into Add/Remove programs and removed the SoundMAX onboard program from there. I then tried the Sound Blaster installation once again. It still said there was another sound card/program detected, but I continued with the installation anyway.
Once the installation was finished, I went back to Add/Remove Programs to make sure SoundMAX was gone (it was) and then went to check in Device Manager as well to see if it was removed from there as well. Welp, now I can't get into device manager. This is what's happening. I right click on 'My Computer' and select 'Properties'. From the 'Hardware' tab in 'System Properties' I click on 'Device Manager' and this is the message that pops up:
"Microsoft Management Console
MMC cannot open the file C:\WINDOWS\system32\devmgmt.msc.
This may be because the file does not exist, is not an MMC console, or was created by a later version of MMC. This may also be because you do not have sufficient access rights to the file."
Any idea what that's all about?
