Computer wont boot to BIOS, just sits

[BitterAvatar]

I have been using this computer for several months now with no issues to speak of. I have made no recent hardware changes, so this current problem is completely out of nowhere.

When I booted up this morning my computer sat at the logo screen that says my mobo type and the 'push Del to enter setup'. It will not move from this point. I can't enter the BIOS or do anything. I notice that my little HDD activity light isn't actively doing anything so it makes me believe that it might be the harddrives, SATA cables, or the mobo connection itself.

I have 3 SATA drives and I've attempted to power on with any combination of 1-3 with their power cables attached with no success, which makes it seem unlikely that all three drives or all three cables failed. This leads me to believe that it could likely be a motherboard problem.

Since I can't even access the BIOS my testing options are limited so I am hoping someone may have ideas or alternatives to figure out what may be doing this.

For reference this is my rig:
Intel C2D 2.4 Ghz
Nvidia 8800 GTX
4gb DDR2 800 RAM
2 Lite-On Drives
3 WD SATA2 HDDs
PCP&C Silencer 750 Quad
Vista Home Premiun 64-bit

May not help but you could try resetting CMOS

Ironic, I get the same problem when I go over my overclock limit. If I were you I would open the case and inspect to make sure all the fans are working and you are getting good airflow including the PSU.

Another thing do you have a Raid setup?
