Question about Dell Computers & Internet
I restarted it so much times and I tried to reboot on safe mood.But no change
You don't mention which model of 780 you have and there are 4 different sizes. However several manuals (in pdf format so can be downloaded and saved to computer) can be found here:
Product Support Dell UK
Looking through them, using "light" as a search term I found these quotes below.
"Solid amber light when the computer does not
start indicates a problem with the system board or
power supply. Blinking amber light indicates a problem
with the system board."
"solid amber - indicates that the system
board is unable to initialize"
From these I would think that the main board (motherboard) on your computer has become faulty, and needs replacement.
Hope this is helpful, if so would you please register that with Fixya

Yellow or Amber lights on the power button of dell computers generally mean power issues. This can be a bad power supply, or dead motherboard.
If the computer is under warranty you can contact dell for a free replacement of the part. Otherwise you may need to contact a local computer repair shop to test which part is defective and have it replaced.
In most cases the data on the hard drive is fine, so you probably have not lost any data due to this issue.

What do the diagnostic led lights show. The diagnostic LEDs are located on the front of the chassis next to the power button. These diagnostic LEDs are only active and visible during the POST process. Once the operating system starts to load, they turn off and are no longer visible. Below is the manual that provides information on what the led pattern shows to help resolve the issue.

spywaregard 2008 is malware, a parasite if you will
the last 1/2 of this article will run down a list of files you need to delte to get rid of this nasty little bugger. You can also download various tools to remove it, but it is dependent on your comfort level. if you are comfortable searching for files and changing a couple of registry keys, then by all means, manually is the way to go. If not, you will not have a hard time finding a tool to get rid of this

i would have to disagree with jerry, while that seems reasonable if the motherboard fan isn't running at all then whether or not the video card is ok is somewhat irrelevant.
I would agree somewhat though, i think the PSU might be a good thing to check to see if it is functional.
when you power it on does the CPU fan start or shudder at least ? that would be my first guess for a problem if you had been having any problems recently

I have an HP that does close to the same thing. Mine goes into a 'Perm-Sleep' mode that I can't seem to pull it out of. I have to remove the battery, then unplug the power adapter, not in that order. Leaving it in this condition for about a minute so that all the power stored in the RAM goes away. This is the same as holding the power button down for 10 to 15 seconds until it completly turns off, sometimes referred to as a 'Cold Boot.'
Once I have powered it down I have to go into the control panel and select the power settings and make sure that hibernate is not an option. If you close the lid on the laptop and the systems goes into a sleep state, it may be configured to go to hibernate after, say an hour or when the battery gets close to being drained. My computer does not like to come out of hibernate and I have to Cold Boot it, so I just don't let it go into a hibernation in the first place anymore.
