Since the 790/990 also has wddm 1.0 vista drivers then they work from dos to windows 7 or 8 or 10 just fine. Other than that, windows 10 works great! Windows 7 professional is housed on the 500gb. However, as dell does not support win 10 no drivers. Many dell drivers can be used on both platforms. To keep your business class pc? Down to use a compatibility, searched many suggestions. The optiplex 990 sold new from dell for $1900. I have an issue with dell optiplex 990, i am getting no bootable hard disk found error. Drivers for the keyboard and connected devices.Ġ7-10-2018 -i disabled the windows defender by following a win10 hacking guide, not just the disable firewall for 30 days or so button that does nothing.

Went to dells driver page for the 990 and it doesn't have windows 10 drivers just 8 and 7 drivers, i was reading. Each are mutually exclusive to the optiplex 990. Lenovo drivers will try to extract to their own, specified path, but that can be changed at runtime. I have downloaded a driver for this type of chipset.Newer computers have the ability to use uefi with support for legacy bios system uefi-csm, but not the 990. Here is what the audio/sound (it is a combo card) specifications are: I have uninstalled the card, check IRQ's, connections, and everything seems to be ok! It was working fine until I did a win 98 SE clean install, so I don't think the audio card is damaged. I went to multimedia under control panel and under audio I can't even access show volume control on the taskbar, it is all greyed out!! Under device manager everything seems to be fine except for the riptide, it audio device, it doesn't have a question mark on it, it has an little yellow exclamation, I have tried a ton of drivers and none of them will work.

Here is what everest had to say about my devices: Everything is working beautifully except for the audio, there is NO sound. I feel helpless!, I have a HP pavilion 8674 D running on Windows 98 SE.
