Re: Desk top emachine powers on
You state that thre are no beeps coming from the PC upon boot. If you remove the memory entirely and reboot, you should get a series of BIOS post tones. If you do not get these, I would first test your power supply to make sure it is working properly. If it is, you most likely have a failed hardware component: either motherboard or processor. If you get no post tones without memory loaded and with a known good power supply, the motherboard will be your problem child.
If you DO get post tones with a known good power supply, try replacing memory 1 stick at a time (if you have more than 1). If 1 works, you have your culprit. If neither work, then you most likely have a bad processor.

Your desktop tower/cpu tower has to be turned on to give those hardware power. If you can't turn on your computer then that means you have an internal problem with your motherboard etc. If everything else powers up except for the screen/monitor your video is dead. Find someone you know that has an extra monitor and hook it up to your tower, if it works then it's not your video but the monitor instead.
Usually when you hear long beeps coming from your computer it telling you that there is hardware loose . You may have knocked something loose. Check cd roms , ports and cards , memory to make sure they are fitted in correctly . good luck
Not so sure about this but I hope this will help.
-try to disconnect all the cables from the back (monitor, keyboard, mouse, usb's, power cable, etc.)
-then disconnect all the card (video card, sound card, NIC) if all are integrated then you dont have to.
-connect just the power cable
-try to turn on the computer and check if it beeps
-if it does not beeps need to replace the motherboard but before you do this check if the fan will spin even for a single second if does not spin then you also need to replace the power supply as well
-if it beeps then turn it off again.
-connect the video card and connect the cable of the monitor, keyboard and mouse
-turn on the computer then check if theres any display
-if theres no display check for any beep indication. and right it down on a piece of paper on how many times it beeps and if its long beep or short beep.
kindly provide an email if this things does not work so that I can give you a resolution.
does it make any beeping sounds? try unplugging all peripherals like keyboard, mouse, usb devices etc, just leave the monitor and power cords and try powering it on again. If it is beeping give me the number of beeps and frequency.
