Hi,
\015\012
\015\012From the symptoms and a breif discussion with Dell technical support its clear that there is an issue with the Video card and the fan located on it.
\015\012
\015\012Run the Dell diagnostics to verify the operation of the fans. If the video card fan is not running, DO NOT use the system - you'll turn a $50 fan replacement into the need to replace a $400 video card.
\015\012
\015\012If this card has been in your system for a while, not a new install, then your GPU is going bad. You might try updating drivers for the GPU and testing the memory, but it looks like a bad GPU chip.
\015\012No changes to your monitor? No chance the monitor cable from the unit is loose, checked the connections on both ends?
\015\012Run the Dell Diagnostics for hardware, on F12 Boot Sequence, drop down to Diagnostics, you can check the memtest, prepost, etc, but you need to drop down and do a hardware test or a system tree test.
\015\012
\015\012Please follow the link bellow to understand how to replace the graphics card.

Dell Inspiron B130 was black when turned on. Holding flashlight to screen, could see desktop and all icons. Was able to open programs, etc., while looking with flashlight. Replaced LCD Inverter listed for B130. It turned on fine, worked about 2 days, then started flickering, and went black again. Could this be power surge from motherboard, or backlight instead? By the LCD Inverter I purchased working for a couple of days, I felt like that was the problem, but something is knocking it out again.
