Dell inspiron 580 not recognizing gpu

logo897 · 28 Jun 2016

Hello all,

I have a dell inspiron 580 and it refuses to detect my NVidia GeForce 8400gs gpu. How can I fix this?

The bios doesn't have a disable onboard graphics option, sadly.

First, make sure you have it correctly and fully seated on the motherboard. What I see this does not require a separate power supply connection but if it does, that is probably the problem.

Second, "clear CMOS" by (with the PC Powered Off) removing the CR2032 backup battery on the motherboard for at least 10 minutes. Reinstall the battery, observing polarity, and then power on and see if its detected.

Do you get any Beeps when you first power one, and if you do post what they are so I can cross reference it to the Dell diagnosic beep chart.

Finally, the video card may be bad.

Hello,

I tested the gpu on another computer actually and you were right, the gpu is bad. Thank you very much for your help I appreciate it.
