This 15 year old Inspiron 560 is to old to appear on the Service Tag site. The generic Inspiron 560 page offers the Service Manual which has troubleshooting.

@redxps630​ do you mean i have to take this red cap of the 2 pins, shove it over the other 1 and middle, then plug and turn on, turn off, and replace the red cap to original position? sorry this is quiet first time in my 37 years i have opened a computer. I know its old computer but used it for personal project on it, if lost it would really stink. i know you guys aint here for the money but the one who can give me instructions to make it work again with all info still on it Im willing to pay 500 dollars as a thanks.

Just remove the battery with the system unplugged and wait 30 min. That will reset the board. While you're waiting, remove and reinstall the memory modules.

If that doesn't get the system running again, you'll have to evaluate whether a repair to a system this old is worth the cost.

There is instruction printed on mobo how to move the jumper to CLR cmos  1-2 Clear

@redxps630 you mean this right? I got ansolutely no idea what to do here or what it means tbh.

removing cmos and replace ram i allready tried.

also i expect not recoginizing any key on my keyboard (although it recognized ky usb-keyboard) should tell me something.

it means by default the jumper is on pin 2-3.  you move it to pin 1-2 to clear cmos.  then move back to 2-3.  try power on PC again. PS if jumper stays on 1-2 PC would not power on

well i still dont understand this jumper thing, but its solved. Part of the problem seemed to be the keyboard, i tried 3 (!) with usb, all no response, decided to find the original dell keyboard (with few missing keys lol) and now pressing the key did something. it recognized the other keyboards but not pressing key on them.

off course ram clearance and battery remove was also part of it, but with these 2 and also using dell keyboard i made it to windows, so great👍
