Maybe iTunes don't want your burning their music. I'm not sure cuz I don't use Itunes, but if it works on others that sounds like it might be the problem.Here I found the below on Apple's site. Symptoms Find out what to do if you can't burn an audio CD using iTunes for Windows. Sometimes an audio disc may not burn as expected. Here are some things to check. Resolution Update iTunes Download and install the latest version of iTunes for Windows. Songs not authorized iTunes will stop burning a disc if one or more of the songs in a playlist were purchased from the iTunes Store but are not authorized to play on this computer. This message appears:

"Some of the files can not be burned to an audio CD. Do you still want to burn the remainder of this playlist? For more information on why some files can not be burned, click below".

There's more so click the link below and see why you can't burn your cd.http://support.apple.com/kb/TS1436

Bad driver disc (or out of date). Use this program : Driver Update Software for XP Vista 7 8 to download and install proper drivers. regards Walter

You can also have a faulty power supply. I've seen many dells meet their demise with junk power supplies. If you are able, and you have the time, try a different one inside of it. it will need to be about a 300 watt 24 pin ATX style power supply with a 4 or 8 pin CPU power plug. (depends fully on what the board calls for.)

Check in the bios on boot up, it may be disabled.

Press the on button quick and don't hold it down. If you keep it on just that millisecond longer it could shut down. Hope this helps. Get back in touch. Steven :D

Looking at the specifications for the Optiplex 755 line I'm seeing the highest power supply is in the minitower version at 305W. I can't find a document specifying the power requirements for the Radeon x1900, but most benchmark power consumption tests show the system pulls around 280 - 300W with that card installed. The problem is either your specific Optiplex 755 configuration can't support the power requirements, I don't know if you have the MiniTower, Desktop Tower, Small Form Factor or Ultra Small Form Factor version of the sytem or the card is itself is bad.

If the system has a BIOS password, then you can clear it using a jumper on the motherboard.

Larry provides great information. Larry Ng Apr 30, 2022 good news the not told at all PC screen is not dead. a major fact but lacks all evidence like: 1, No PC told no OS told xp to w11 2: fans spin? all do, psu ,cpu and gpu card if fan. 3: Optiplex is a desktop 29 years of models made wow. 4: you mean Dell Splash logo. yes, and then it does the post bar, if post bar stalls that means hardware gross errors. sadly no PC model told of vast versions. wow. just wow hopeless that.? but is par here, and vast wrong answers just for that fact alone.even mine. i have many optiplex PC here old and new and my fav is 9020MT or smaller my oldest is 380(in storage) is your coin cell dead. (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.

Please see picture below

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. (called PICO plug)why not buy a new PSU? that matches this PC?even the SFF PSU case is not ATX spec.https://downloads.dell.com/manuals/all-products/esuprt_desktop/esuprt_optiplex_desktop/optiplex-960_service%20manual_en-us.pdf

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
