This sounds like a hardware problem, but it may not be particularly serious - it could be the VGA cable has become slightly loose and pressing it home on the PC and monitor may fix it.
Yes, there are. Try this one. http://spacefem.com/mnemonics/

This has to do with the electromagnetic spectrum. Whether you know it or not, Gamma-rays, ultraviolet, X-rays, microwaves, visible light, infrared, and radio/tv waves are all the same thing, just in different doses. Infrared literally means "below-red", while ultraviolet means (beyond or above violet, or purple). With fore-said spectrum, visible lights highest frequency color appears to us as purple. At a slightly lower frequency we observe blue, then green, followed by yellow, and eventually red. In between each of these colors we observe intermediate colors like magenta, teal, orange and pink. At a frequency lower than, or below, red, we begin to enter the infrared area of the electromagnetic spectrum. Above purple, we enter the ultraviolet area of the electromagnetic spectrum.
EPROM or Erasable Programmable Read Only Memory was invented by Engr. Dov Frohman. It is a ROM-type chip that can hold data from 10-20 years. It is different from PROM because it can be programmed more than once. An EPROM programming is erased only through exposure to ultra violet light. The EPROM is configured or reconfigured using an EPROM programmer.
Solid-state storage, known as ROMs. Read Only Memory.Some are programmed once only and retain their program material with no power at all.Others may be EAROMs (Electrically Alterable Read Only Memory), where the data is stored in long term capacitors and can be altered by programming with the correct voltages applied.Others are erased by ultra violet light and can be re-written, but hold the data with the power off.Removable types, would fit into the category of flash memory cards, or USB sticks.These contain IC's which hold the data stored on them, allowing for easy transfer of information from one device to another.
Violet and purple are similar colors but not exactly the same. Violet is a spectral color with shorter wavelengths, while purple is a mix of blue and red. In general, violet appears more bluish and purple appears more reddish.
When white light shines on a violet object, the object absorbs most of the wavelengths in the white light spectrum and reflects primarily violet wavelengths. This means that the violet object appears violet because it absorbs other colors and reflects violet.

A violet dress appears violet in sunlight because the dress absorbs most of the other colors in the sunlight spectrum and reflects back violet light. This selective absorption and reflection of light give the dress its violet appearance when viewed in sunlight.

Violet and red-violet are made of red and blue.
There are five colors between Red and Violet. Red, Orange, Yellow, Green, Blue, Indigo, Violet.
Blue and red will give a near violet colour.
The color violet has the highest energy among the visible colors. It has the shortest wavelength and the highest frequency in the visible spectrum.
Blue-violet is typically made by mixing the colors blue and violet together. Mixing blue and violet in varying amounts will produce different shades of blue-violet.
