I seem to be having a problem with my screen when I boot up the computer, either from sleep or shut down, my computer monitor flickers and the colors on the screen are faded for about the first 10 minutes. Then, the color is restored back to normal...Even if Im using the computer for a while, then all of a sudden shut the computer off and reboot it, the same problem still occurs..
If anybody could shed any light on this matter, it would be immensely appreciated.
It sounds like a problem with the video card, whether it be on-board or a card. See if you or a friend has a spare one laying around and try that one instead. If it's not the video card, try a different monitor.

you are cold booting the pc always shut down normally when you shut down just useing button it will eventually corrupt the system I have several computers and never shut them off at all unless installing new hardware if you get a keyboard with the specific button just for the sleep mode this problem will clear up but if you shut down normal it will work rite
sounds like your windows installation took a hit, try booting from the windows cd into the repair console and do a chkdsk /F /R; a fixboot and an fixmbr command. if ths doesn't work, try the repair option. You can also try to boot from a hirens boot disk and try the tools that come with that.
Three possible causes of sleep mode. first, an extensive screensaver with password lock prevents display. A condition that is observable as a blankscreen also known as sleep mode. Second, a computer power saver settings that shutsdown during idleness. Third, An improper shut down of the computer would have caused a sleep mode to save the system data files.
Restoring the computer to regular functionalioty
First solving predictable sleep mode settings
1. A movement of mouse pointer across the screen should reestablish unprotected password modes
a. password protected sleep mode would display an promp message requiring key code soon after the mouse pointer has changed direction
sloving unpredictable sleep mode settings
1.A computer power saver, screen saver, or splash screen displays prevnting programs acess would require manually powering off the computer system.
a. A manual power back on of the system should restore to program functionality mode
1. contact expert technical assistance
If you can restart it and it starts up fine, then I would go into the power settings and disable sleep mode. Every computer is different on how to wake a sleeping computer, so you could read through your manuals and find out for yours, but I just disable sleep mode on all computers so i dont have to hassle with it.
Could be a power supply. Fluctuations in that can cause power drops, which would be visible in the video card, and if severe enough, cause the PC to shut off. There are 4 screws and one 1 wire holding those in. It would take about 10 minutes to replace and probably cost you $40-$50 in parts.
