Big Problem

Trouble shooting the power suply to make sure it is starting up and the fans are spinning

Check the CPU,listen for the fan to start,open the case to inspect

Check the memory slpots to make sure they have not crept out,and are making good contact

Try using another video card to see if this is causing the problem

If all else uninstall all cards except the video card and boot the system,with no beep sounds coming from system it looks as though you have a motherboard problem

I would recommend that you take everything out your PC and just leave in the CPU, RAM and Graphics card.

You dont say what CPU you are using.

Try some different ram if you can. Faulty MODEMS can cause the PC not to boot.

If none of thesethings work I would suspect the mainboard. IS THE CPU FAN spinning OK

It sounds like one of your devices is bad. Start with the cdrom, disconnect the cable (the data interface cable) and reboot. If that is not the problem try the hard drive cable next. This is caused buy the post, it checks all the system devices first and if one is not responding it halts the system. If you hear the the system start to come up, ie. fans, lights, memory and hard drive check but it stops there. You have a bad device.

try changing the slot for the graphic card...check for any loose connection in the cables... get some working pc's ram and test on your pc..last but not least get another bootable hardisk and use on your own set ... see which one is causing the problem..

I don't know what OS you are using, but I ran into a similar problem with a client's computer. They were running WIN98SE and had a bad modem. The system would boot OK most of the time, but if they had any problems connecting with their modem (fax orinternet) the MB would freeze. We eneded up replacing both the modem and video cards to correct the problem.

im running windows XP, and im worried its the motherboard because that controls every device/drive in the comp, and right now nothing is working. also it houses the BIOS info, and i dont even get so far as the BIOS screen. just a blank screen immediately and no noises except for fans and hard drive spin. i tried taking out the modem, that didnt work. i tried a different vid. card, it was only a 8MB card, so im not sure if its even powerful enough to power my comp. but i would think it could at least get the BIOS screen up. any advice to this input is greatly appreciated.

Check your cables make sure they are oriented correctly. I have had my system not show anything because an IDE cable was backwards on one end. Also try different RAM.

If you fallow some basic steps you can find out what went wrong and why. First disconnect every device connected to the system. Take all the cards except the video card out of the system also disconnect all drives, ie. hard drive, cd-rom, floppy. Now try to start the system. If it works start to reconnect devices starting with the floppy back up to the motherboard. Try starting the system after each device. If the system doesn't start you've found the problem. If after you've disconnected everything it is still not starting then I would try replacing the easiest things first. If you have more than one memory stick that all of them out except 1 or 1 pair then swap them out to test each one until the system responds or you have gone through them all. Next because of the nature of the problem I would try either the cpu or the power supply. It just depends on if you have any spare laying around or how much money you have. Good Luck!

I have encountered the very same problem. All of a sudden out of the blue, on a perfectly good pc, nothing happens - except for the fan and the hard disk spinning.
No beeps, no POST, no screen display, no nothing.

What did I do? Changed the whole motherboard. Reused everything else.
That's nearly six months ago. And no problems thus far.

Maybe u can give it a try. Be a good buddy to someone for a couple of weeks and he might just let you borrow his motherboard ... to experiment on your own pc.

Don't think anybody suggested this so far. Did you try clearing the CMOS? I've seen computers that seem dead and with a CMOS clearing, they're good at new.
