PS makes all right sounds fans etc.
but monitor set to wrong input port, via OSD.

that is it for now. lots more causes. we need all symptoms to progress.

what model do you have? most older emachines, gateway and dells are very similar...1) round purple ps2 to keyboard, 2) round green ps2 to mouse, 3) teal oblong serial 1 is older output to modem, 4) blue oblong vga output to monitor, 5) reddish long oblong is parallel port to printer........ all these are usually not used on newer models...others include a white oblong for dvi to monitor, or small rectangular for hdmi to monitor, as well as the traditional usb 2.0 and usb 3.0 for a multitude of input and output usages...... small round female ports are for sound.. pink for mic, green for main speakers, black for rear surround, gray for side surround, orange for center surround, and blue for line in....may also have an esata port (not used much) and a ethernet port for internet connection (looks like a slightly bigger telephone jack port).... might have a spdif (sony phillips digital interface) for digital audio.....hope this may help...

Put a piece of tape over it

blinking power button indicates a low or missing voltage problem. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

Just a standard Power Supply will work for this machine. Roughly 400W will do it, there about $30-$40.

please check the monitor or LCD that you have. because the computer will not flicker if there is a problem on the display. isolate it. use other monitor or LCD then check if it flickers again.

the only reason to have removed them was to switch the board or put the board in a new case..if you put a new board the new board is what you have to go by, look in the book, or take the number off the motherboard and go to yahoo and type in schematic for xxxxx board.
DO NOT go by emachine model as its worthless, too many models have different hardware.
This is all basic repair 101, how do you have customers? lol

the is a small program called Userinit Fix available here, it will correct the boot loop..
