Randomly one day my computer screen looking like it was seizuring then went black then came back to normal and said in the corner that the graphics panel had stopped responding. It later seizured again and this time the whole computer shut off. Now when I try to turn it on, the screen is black with flashing colorful lights in different lines all over it. If I connect the laptop to a computer monitor, it shows up fine and can sometimes boot up all the way in safe mode, but eventually blue screens saying there was a hardware issue and shuts off. Help!

The OS-loading screen is a stong indicator that thee is nothing wrog with your hardware, but it is a driver issue. You need to press F8 as your computer starts up and enter SAFE-MODE. Windows 7 Using the F8 Method:
Restart your computer.
When the computer starts you will see your computer's hardware being listed. When you see this information start to gently tap the F8 key on your keyboard repeatedly until you are presented with the Windows 7 Advanced Boot Options screen as shown in the image below.
Figure 11. Windows 7 Advanced Boot Options screen
Using the arrow keys, select the Safe Mode option you want.
Then press the enter key on your keyboard to boot into Windows 7 Safe Mode.
When Windows starts you will be at a typical logon screen. Logon to your computer and Windows 7 will enter Safe mode.
Do whatever tasks you require, and when you are done, reboot to go back into normal mode.
In safe-mode remove & delete the drivers you installed. If you can, revert to your old driver set.
christelledt, When black screen of death rears it's ugly face, the first thing to do is look at the "date of manufacture" on rear of the unit! If unit has lots of "ON" time (300 days/year x 8 hrs/day x years in service) it may need to be replaced or refurbished. 7 to 10 thousand hours is middle to old age in monitor life. If unit performs in same way when connected to different pc then you will trade-in for new or investigate a DIY refurbishment of the units internal ac to dc switch-mode-power-supply/CCFL inverter printed circuit board. unit may need $5 in capacitors replaced to fix it. Plenty of info and videos on that on the web and here at fixya. 12fixlouie
I agree with NeoDude007, Sometimes Windows update will find a video driver maybe newer that the one you are using but sometimes it will screw up the resolution or color quality.
run cc cleaner great free tool and dl latest nvidia drivers hows your screen lcd or crt is it old ? does it do it on anther computer your screen ? can u reseat the video card is your case full dust hot ? blow it out
Regarding the screen jitter, believe it or not, the infrared port is causing the issue. If you disable it through settings inside the unit your issues will go away. The sun basically destroys the infrared sensor and the unit "thinks" a button on the remote is getting clicked continuously.
