If you computer gets to hot it mess up things. don't use a computer on the bed it will keep the heat in the computer there are air ways under some laptops for the fan and if the fan can't blow heat out you laptop will soon have problems. One other thing, Laptops are not made to run like Desktops.

The colors on my laptop's screen are inverted, how can I fix this?
Both OS X and Windows have inversion options for their displays. Their meanings, on the other hand, differ with the operating system. An inverted display on Windows refers to the display actually being upside down, while an inverted display on the Mac refers to the colors being inverted. Either way, these options can hinder the use of your computer, for obvious reasons. Luckily, an inverted screen can be fixed quickly, on both Windows and OS X.

Right click on the Desktop and select "Properties." Click the "Settings" tab and then select "Advanced." Click the "Driver" tab and then "Graphics Properties." Press "Display Settings" and uncheck the "Enable rotation" option. Click "Apply" and then "OK." On Mac OS X Click the Apple logo in the upper left hand corner of the screen. Scroll down and select "System Preferences." Select "Universal Access" and click on the "Seeing" tab. Check the "Black on white" option and the display should return to normal. Close System Preferences to save the changes.

your laptop display mass color, it is not the issue of inverter.
there are two situations:
1) mass color you can not see any messages like letter or picture
2) mass color with some or any messages you can see.
above situations you need to check LCD sreen cable connection between LCD socket and the motherboard socket, plug back properly.if not fixed, there are some tips you may consider:
1) change the Ram if the display ram is not isolated.
2) the LCD cable damage need to change or
3) LCD screen damage need to change or
4) finally the motherboard display chips damage(rare)

HP Pavilion DV7 Display problem
How long have the colors on your display been "reversed/inverted" and looking like a negative....... Did you drop or damage the laptop in any way (sudden shock/bump)? Also, has it been allowed to overheat (if you run the laptop while it is sitting on a soft surface such as a bed, pillow, couch, etc it can allow the motherboard to overheat because it cannot get the airflow through the cooling system through the fan/vents because they are blocked). Have you checked to see if your laptop is included in the "HP Service Enhancement" program???

The pictures on my compac presario laptop model V5305WM look like negatives, or xrays. This problem appeared overnight.
Are you talking about the thumbnail view or when you open the pictures in a specific program? Please check the program settings viz. view, edit, tools etc. and see for any option to invert colors or so.. 
If this doesn't help then you may also check the display settings for your monitor.. however that shouldn't just affect the pictures on the computer , anyway..

Negative/inverted pictures
If the images in the camera are inverted , then could mean repair or replacement is the remedy and I suspect only replacement will be the answer.
When you say Photo Gallery- do you mean as displayed in your computer after uploading?
If so then an image editor such Irfanview or Picasa will revert them.
