I'm in the process of upgrading an old E-machine, basically just replacing the mobo and CPU. I'm re-using the hard drive CD/DVD drive, floppy etc. I installed a FoxConn 661GX7MJ-H LGA 775 Micro ATX along with an Intel Celeron 420 512 kb L2 Cache CPU (Basically this matched more or less what was in there, while keeping things fairly cheap. Anyway, I get everything back in the case and hooked up, I connected a monitor plugged it in and.....nothing. Nothing came up on the screen at all, I checked all the connections, everything is connected properly, the IDE cables are connected right (nothing reversed) the memory board is seated correctly, all the fans work and the VGA connection is tight. I've built a couple of computers before, no problems, this really has me stymied because I don't have a clue on where to start, the monitor is good so thats not the problem, the only other thing I've noticed is the little hard drive led on the front of the comp flashes, (I even changed the HD but still nothing. As far as the CPU goes (it's that LGA 775 with the pins coming up from the mobo) no problem there, (the chip fell right into place) Hopefully somebody can give me a couple of ideas on what else to check. :thumbsup:

There is a problem with taking a hdd with a OS installed on it from one machine and installing it in another. There are key points in the registry which have been recognized from the chipset on the motherboard, and when you install that hdd to another motherboard it sees the new chipset and gets confused. This usually will result in at least the need to run a repair, or it could result in your needing to reinstall the OS.

Can you get into the BIOS? If you can, make the CD-ROM the first item in the boot order and see if you can boot from the installation CD for your OS. If you can boot from the CD then you OS is the problem.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

All I can suggest is to take everything out of the case and try it on the tabletop, on a piece of cardboard. You said it's an old eMachine. Do yourself a favor and get another power supply

Actually it does have a new power supply in it, but the fact that the hard drive might be the cause of the problem intrigues me. I was told that using the old hard drive would cause no problems, and indeed was working fine when I turned off the comp, and replaced the mobo and CPU. I may have access to a new (and blank) HD, I'll try installing it and see if the machine will boot up.

You should at least get the BIOS when you're starting up, even if you don't have a HDD plugged in.

Is the RAM in tight? Thats all else I can think of. (Although you said that, didn't you?)

Don't forget to make sure that the BIOS jumper (if equipped) is set to Normal. If it is, reset the BIOS and try again.

D'OH :thumbsup: I should've looked up the specs and done my research earlier.

Yup, Celeron D, not a celeron 420

A Celeron 533 D ya say............ooops! maybe this has been my problem, I'm trying to use a Celeron 420 Conroe-L 1.6GHz. Others kept telling me it wouldn't boot if I was trying to use the old HDD, (this is what the mobo mfg. FoxConn told me) Well I'll certainly check into this, thanks!

I wouldn't exactly equate telephone tech support to the level you have available on a forum like this.

No one knows that much about everything but when you add up the resources here at Bleeping, it's "strong with the force"
