Most likely a problem with the card. They tend to corrupt easy enough. Try formatting the card.

Onboard sound does not need drivers. The little speaker is attached to the motherboard directly or by wires plugged into the motherboard. You need to check to see which speaker you have. Once you have found out, be sure that, if it has wires attached to it, that they are plugged in.

With your Dell computer's "Tag" number, visit their support website and enter that number to bring up your machine; from there you should be able to find/download your drivers.

(if yes can NOT be ignored) my dells all have F12 diagnostics, power on and hammer F12,, pick diag eSPA and run it older PCs dell if the HDD is dead the F12 diag is dead. due to being located there back long ago. my dells have a BIOS log page, go to BIOS the click tab, LOG read the logs. see what fails. (coin cell RTC sure)_ easy no?\ but why on earth post lacking the model number making any useful simple help 10 pages long for 29years of models. 1993 is the first OptiPlex, seen here. https://en.wikipedia.org/wiki/Dell_OptiP... nobody can guess and no era is the same. evolution max. ..

What is the exact error that you are getting? Do you get any blue screens? Have you installed any software recently or made any changes? I can only suggest checking the power cables and trying to use a different cable or spare if you have any for now.

Sounds like your on Google Chrome, this has started popping up since the last update and only on secure webpages at random, try running Windows Update and make sure it's up to date, it check the root certificates which should come with the windows updates.

ok 960 SFF is not the same as MT or the big case MOBO.SFF has its own mobo (motherboards)it has 11x2 row non ATX spec, power . not yours as it has 12x2 some SFF have 2 diffr. moboand a dell custom PSU for just this mobo and its odd duck jack.

Go into device manager. Uninstall audio driver. Restart computer. This will reinstall the default driver. Try again. If it doesn't work, go to Dell website to find specific driver for your computer (using the service tag) and install that.

Desktops PCs usually have a 'jumper' on the motherboard, inside of the PC, that resets the BIOS, removing the password but also changing some settings to their defaults. It takes some 'know how' but you can google it to help you locate it.

What are you talking about? Video card?

You are getting blue dump on start up or after booting in to the system
