Dell Inspirion 660 is beeping when trying to boot up

It could be many things honestly. A couple possibilities could be; you put in too much RAM/not the correction offset of RAM; CPU issues; System fan issues (though some computers will let you run it anyways pressing F2); Power supply issues; or something errored on the motherboard. Those are just a few off the top of my head. If you recently installed RAM, try putting things back the way they were previously and look online for your max RAM support. If not, look on the back of your power supply and you should see a brightly lit green LED. If it is dim, pulsing, or off...you will need a new powersupply. If light is bright and on, try opening your case and making sure all of the cables from the power supply are firmly in place on your motherboard. If after all of that and your computer is still having issues, you might need to replace your Motherboard/CPU, or both. Hope this helps. :D

SOURCE: very slow boot on 660 inspiron

The first thing you can try is to start up your dos shell, Inside the dos shell type chkdsk /f this will run a check on your registry etc and will fix any issues that it may have, Please note that it will get so far and tell you that it could not perform an action as windows is currently being used do you wish to run this check the next time windows start, Tell it yes by typing y press enter and restart it will perform it's checks and if it finds any problems it will fix them and generate a report at the end to tell you what it fixed. If this does not work, Try updating your BIOS from the Dell website this can be found under the driver and support section you can download it or do it on line ( Best Off Downloading as it will restart your system into a setup type screen and you will loose your internet connection. If after all this and it is still very slow at startup contact Dell support for further technical assistance. I hope this helps.
