Download the audio driver from http://www.dell.com/support/drivers/uk/en/ukdhs1/Product/inspiron-5160

you mite have fried the power supply. or the battery.. try removing the battery and pluging it in,and then power it up

If the monitor works try hit ctrl alt f3. if that works you might have to reset your resolution

there is an adjustment for that on labtop

u need to update ur laptop BIOS or change it

The only way you are going to get any enhanced audio out of a 5160 is with an external USB audio device.

One option: PCMCIA Sound Blaster® Audigy® 2 ZS Notebook

I think its the end of the monitor. I dont think there is anything that you can fix in this.

Inspiron 5160 is probably at least 3 or 4 years old. If it is running slow, (and maybe fan is running all the time and fast) you might need to check if the heat sink/fan assembly is in need of cleaning. You have to remove this assy from the laptop, and remove all the accumulated dust and gunk from the INSIDE of the copper fins. Inside meaning remove the fan from the assembly and with a fine brush, GENTLY remove the gunk from the fins, or with the fan removed, try canned air.
