New Build: Can't get past CMOS screen

[janeandgus]

We have just assembled the following components:

Motherboard: Jetway J775GT4-G
Processor: Intel Pentium D 775 Dual core EM64T
System memory: WINTEC AMPO 512 MB DDR2 SDRAM (2)
Power supply: Cooler Master extreme power RS-430-PMSR/P
Video card: Rosewill R6600 256SLI Geforce 6600 256MB 128-bit DDR PCI Express x 16
Western digital 80 gb hard drive
Airnet AWD108 32bit PCI wireless card


CDRW, DVD, floppy drive, keyboard and mouse have been scavenged, mostly from a Dell (vintage 2001)

The sytem starts up, and we have gotten as far as the standard CMOS screen-- at some point the keyboard seems to be no longer connected to the system-- we cannot make any changes in this screen, and after a few clicks, we can no longer navigate. Is the computer crashing? Is it the keyboard?

The motherboard has three jumpers associated with the keyboard/mouse power (PS/2 ports), and USB power (two jumpers for several USB ports. We have tried two different keyoards, a Dell and a no name both PS/2 and USB. These are now at there default setting, which shows up in the CMOS as "Halt on: All, But Keyboard".

We have also tried starting up with a boot disk in the floppy drive, and/or a boot disk in the CD drive (Windows XP Media version)-- doesn't make any difference.

Any ideas about what to try next?

THANKS!

Try first to clear the BIOS to default settings(pull the battery or CMOS reset jumper if available). If this doesn't work, you need to do an out of case test to make sure something isn't shorting the keyboard jack.

Thanks-- I reset the BIOS with the jumper--same thing is still happening--

Can you tell us how to test the components out of the box?

[janeandgus]

I found this in the PCMech online manual-- I wonder if this is the problem--

"If, after several minutes, the heat sink gets too hot or the temperature readouts become abnormally high, or if the PC Health screen freezes and you cannot do anything with the keyboard, then you likely have a cooling issue with your processor."

The temperature is 88C/200F (+/-) on startup-- this seems high to me-- but I am not sure wht it should be. What do you think?

OMG, 88C on start up? Is the heatsink/fan on your CPU working?

[janeandgus]

we will replace the thermal interface material and se if that solves theproblem-- the fan on the heatsink works.

:) problem solved!
