I recently migrated my mobo into a new case, but found that now that the comp won't boot. At first it booted telling me that the Cmos Setup was wrong and that the Time and Date was not setup. So I shut it off and turned it back on a while ago only to find out that it won't boot to POST or nothing (at least, nothing shows on screen). The HHD LED light stays on as in active, the fans all spin as well. I tried removing the ram to see if I get that post beep and I do. Any ideas on what could be wrong?

Try removing any and all USB devices from the PC that are not needed to boot the system. It could be that the USB devices are hanging up the boot process because the system has not had time to load the USB drivers yet. This may cause your system to hang on a new install.

If this doesn't work, try booting into Safe Mode and take a peek there and remove the video drivers and then reboot the system and let them reinsall.

If the computer lights up but doesn't POST at all then that means the motherboard isn't recognising that there is a CPU in the system. I would try removing the CPU then reseating it and trying to boot it up again. Hopefully this will fix the problem. You may also want to try clearing the BIOS.

That sounds very much like a dead battery (the battery itself, or not present, or installed upside-down). It's cheap to replace it. Once replaced, rerun your BIOS setup, see if it holds.
Note: this also happens when the IDE cables are poorly seated, or when the M/S settings of the drives are incorrect.

That's a good sign.

Try disconnecting everything that is not absolutely essential for the machine to POST. Yank the IDE devices, PCI cards, floppy drive, even the CMOS battery.

Then try powering up again.

Good luck,

Come on, PSI, of course, removing the RAM will cause beeps.
You are on the wrong track...
Explain to me what it is good for to remove the battery.

It won't cause anything if the board is fried. The fact that it does beep means the mobo is in good enough shape to get at least that far.

Explain to me what it is good for to remove the battery.

Even with the battery removed, a computer will still POST. Without the battery to allow the system to maintain the old CMOS settings, the BIOS will revert to the default settings. So if, for example, a screwy/corrupt BIOS setting is causing the system not to POST completely, this action could help. In any case, at this point it is better than doing nothing.

It is possible this problem could be caused by something not being seated correctly (i.e. a PCI card). So yanking all the nonessential stuff will invalidate this possibility.

Most motherboards will have a set of pins on them that can be jumpered to revert the BIOS to it's default settings. This is especially useful if you have to clear your BIOS multiple times because it's easier than trying to flip out the battery.

I just noticed that this thread was started in August...

Not most mobo's have that jumper - they ALL have it. So, removing the battery is indeed good for nothing - except for replacing it.
Starting it up without memory will not help for anything. The mobo does work - at least sometimes.
