multiple things could be the problem, you'll have to do some troubleshooting.\n\nFirst I would check that the monitor is plugged in correctly and powered up. There is a plug, ususlly blue, plugged into the back of the tower and leading to the monitor. two manual screws hold it in place. untighten the screws to see 15 pins. make sure all pins are intact and not bent. plug it back in tighten screws, power on pc, give it a second and see if it works. if not... \nNext I would check the monitor on another computer or try another monitor on the first computer. If the monitor is not fried, its likely you have a video problem. \nIf its a video problem, you are going to need to get a video card. ask at your local computer store. buy, or borrow one from a friend for testing. you might want to open your tower first to see what kind you need.\nGet some canned air and a small screw driver. \nBefore you open the case check to see if you have onboard video or a video card. You can do this by seeing if the Video plug(vga 15 pin same as before) is located behind your I/O shield (where the printer port, mouse keyboard and usb ports are) which would mean its onboard. If it is in one of the long horizontal slots, its a card. \n\nunattach the VGA cable and Open the case. Its usally either a screw on the back and then sliding it off or a handle that you can use to pop it off.\nBefore touching anything make sure the power is off, but the computer is still plugged in and put a hand on the metel case to ground any static electricity in your body. esd can damage your mobo. \nplug your nose and close your eyes and blow out that dusty mess with the canned air.  \ninside is a mess of cables that can be scary but bare with me you are looking for a speciffic thing. you should see the power supply with all the multicolored cables running to the cd rom hard drive and other stuff. Then there is likely some IDE cables (flat ribbon cables connecting the motherboard to the hard drive and cdrom.) on the mother board there will be some slots (usually white) that correspond to the slots on the back of the tower. in these may be the video card, if so you have a PCI video card. If the card is plugged into a similar slot that is shorter, set back more, closer to the inside of the motherboard and probably brown or blue (also corresponds to a slot in the case usually the highest slot), it is AGP. If you have onboard video just see if you have an AGP port so you can get an agp video card. (note there is a new technology called PCI express but unlees you bought your computer in the last 6 months don't worry. ill assume you haven't otherwise you'd just use your warrenty)  \nso get yourself the correct video card (agp or pci agp is better).\nPull the old one out (unless you have onboard video) \nThe long piece of chrome metel attached to the video card is bent at the edge and there is a screw in the top. (or there is a clip over all your expansion cards) unscrew or take this loose. agp cards sometimes have a plastic clip on the back to keep them from popping out, unclip this.\npull strait up on the card, some force may be required but don't break it. handle all circuit cards by thier edges only as much as possible to avoid esd. \nUnpackage the new (or Known good) video card and insert it the same way you pulled the old one out. make sure that it is seated well. put the screw or clip back in place and close up the case. \nattach the cable to a known good monitor and power up.\n\nif this doesn't change anything, its likely that your motherboard is freid. if this is that case you will need to have a professional work on it for you or just buy a new pc.\ngood luck.

Reset CMOS. Better still, remove and replace the CMOS battery.  If that does not work, then you need to have the motherboard tested to see if the back panel connectors are working properly.\n\nEdited- PN   she said she already checked the keyboard on another pc, besides if the CMOS battery dies, it can do so quickly so you would not be able to tell if time was kept properly.  This is from years of experience with PC repair, so before you answer, read the question.

Please do the following procedures step by step until your problems are solved:\n1.open the computer case\n2.unplug all interfaces, cards and cords. (you are supposed to spray on the monitor and VGA card connector too.)\n3.spray the electronic connector cleaner onto all connectors.\n4.plug on all interfaces, cards and cords.\n5.power on\n6.Hit del as soon as the computer reboot.\n7.Hit F6 to restore default setting of bios.\n8.reboot\nIt's supposed to function well if you has completed all the procedures as above. If it is still not working, tell me the symptom, I will help you.

you have a bad video card, oth e onboard chip is bad most likely, if you have onboard video, try taking the ram oud and reseatin git, if you havea video card, do the same, if you still have not video, start thinking about a corrupt bios, or a new motherboard

run dxdiag and it will tell you everythiing about your computer dont be scared to open your tower and get a better look @ the moutherboard to see exactly what your working with

Try turning on the monitor, see if it is plugged in right.  If none of that works don't hit it with a sludge hammer, bring it into a computer store.

Make sure the internal connections are still there, and then reinstall the drivers.\n\nmaybe its just busted.

Is there any beeping when you start up your PC?  Have you made sure that the cable is securely connected on both ends for the monitor?\n\nGenerally if ram has bad sectors in it, the PC will still boot up.  I am not sure if this is the same for a video card, but I think so.  Have you made sure the video card is in its slot all the way?  I would open your PC and check.  Oh and have you recently installed any new software or hardware?

Check the connection.  Most problems are a loose connection, or a bent pin.  Also, make sure that nothing is depressing any of the keys when the computer boots up.  If the keyboard is sending signals to the computer during the boot phase, it may register as an "Keyboard Missing/Error" message.\n\nOtherwise,\nTry another keyboard.  If it works, then your keyboard is faulty (cheap to replace).  If the other keyboard doesn't respond, then it might be the connector on the motherboard (which is very bad).\n\nHope this helps.

There are several problems which cause no display on monitor. \nMight be due to bad SMPS power supply... Check the back fan is working or not...?? if yes there might be problem with ur Mother board. u can check with the beep sound when starting PC...\ncheck the RAM & Processor....

do you see ANYTHING during the boot process?\n\nif 'No', then disconnect the power and open the case and verify that the video card is pushed-down all the way.\n\nif is 'onboard video' (ie the vga connecter is up by the keyboard & mouse & audio connecters,) then try to plug in a different monitor, see if a different one displays...\n\nmake sure you're taking the Monitor's power cord or power supply with you to the P3 machine....  :-P\n\nHope this helps !

I'm thinking it's a power supply in the monitor.  You might want to try another monitor to assure yourself that the problem is indeed with the monitor.

check if the cables are plugged properly. if you still get no sound, and if you are knowledgeable enough, reseat the sound card on the tower. u can also try other speakers. dont forget to turn on the power and volume of course ! :P

I think it is problem in your BIOS settings. It is trying to detect a hardware that is not functioning. So try to correct the BIOS settings.

This sounds as if your power supply on the PC itself went bad.  Especially if you have checked all your power connections, and you are still on getting power to your system.  \n\nyou may need to contact E machines and see if your system is stll under any warranty.  If you have any Geek friends, have them check it out to make sure its the power supply, and not the motherboard, memory, and/or processor.

Check if you have all the correct drivers installed. You said that the PC had recently been formated so it could be as simple as incorrect video or mouse (trackpoint, touchpad) drivers.\nYou should check the manufacturer's support site to get the latest version of drivers. If you don't know the address just post your make and model and we'll try to find it.\nHope this helps!

Check the cabling between the monitor and the PC. It may be a bad connection.
