Is original then here's a few options.
Do you have factory disks? Some of the disks that Dell sent with some computers had something wrong with them. You can request 1 set of disks from here.
Since you didn't mention your operating system, the rest of this will be general.
Dell's website has the drivers that you need for your computer. Dell recommends that you kindly log on to http://www.support.dell.com for updated version of drivers and other downloads
Please download the drivers from these links (in this order)
Desktop System Software or Notebook System Software
Chipset or SMBus driver
Processor Driver (if applicable)
Input Drivers (keyboard/mouse)
You can try putting in the disks and try this.
Go to start
click on run
type sfc /scannow (space between the c and /) hit enter
It will fix anything that wrong with the system files.
I have a Inspiron 9300 since 05 and all of a sudden a I have crashed three times with serious error and have developed three 1 pixel lines in my LCD screen. I do not know if these two things are related just seemed to happen about the same time.
The lines on the screen I traced back to a recall problem but Dell says my part number of my screen doesn't match the ones they say they were having problems with even though everything else matches computer model time frame and the actual problem and they will do nothing to help without large fee probably because I am out of warranty?
The error I am getting when the computer does its serious crash is BCCODE: 10000050 BCP1: E11FF5F6 BCP2: 00000000 BCP3 : 804EC8A3 BCP4: 00000001 OS VER: 5_1_2600 SP: 2.0 Product 256_1
I send report but I get no response so I don't know how that is suppose to help me.
