Dell Inspriron 1545 Screen Problem

Hello,

I have a problem with my Dell Inspriron 1545, the laptop has it's usual way of turning on with it's logo and everything. After the wait and logo, I enter my password that I've set and as it gives me the normal "Welcome" and the "spinning ring" (is what I call it). After that, my desktop is blank (with the exception of the color of the desktop that I have set [which is a light army green] and the arrow [and spinning ring sometimes]). There's absolutely nothing, no faint images all but my expired McAfee (that is i guess, "built in") find it's way of being shown for a second and disappears as usual. I've tried to right click but is unable to see the "drop box". Ctrl + Alt + Delete won't even work, the color green has never became so annoying in my life.

Before all of this madness, I turned my laptop on and it's going great so far. I enter my password and I see my desktop with the icons and start bar, but without my "special bar" that acts like a knock-off of a Mac's icon bar and the vista side bar with my applications. I noticed nothing would load like the internet connection and anything I (double)clicked. Nothing showed up, so I planned to restart the laptop. I restarted the laptop, the desktop faded away with everything else as usual. The "Logging Off" oddly took forever (possible 8-10 minutes maybe even shorter because of my impatience but I knew it was pretty long). Eventually I became tired of waiting and aborted the restart by making a hard shut down. The long "Logging Off" problem has happened before when I wanted to shut down the laptop and so I made a hard shut down, but when I turned it back on everything was fine... Until this happened.

Please help me find an answer.
