My brother and I were putting this a new PC together in a Thermaltake Mambo case with the following components:

Intel DG965 RY motherboard
Pentium 4 641 3.2 GHz
2 GB or RAM
320 Geforce 8800 GTS
Thermaltake 550 W power supply

When we were testing the PC with those components, there's been some issues. We reset CMOS and the RAM, but nothing shows up at the monitor. Any way to solve this?

The most common cause is that the CPU fails to initalise (so no POST occurs) due to brass standoffs from motherboard to case are incorrectly locates, shorting the motherboard copper tracks.

Have you tried it outside the case, with the motherboard on a piece of cardboard?

Also need to make sure the four wire (2 yellow + 2 black) power connector is plugged in near the CPU, and power is connected to the 8800 GTS.

The scenario you describe is fairly common on socket 775 processors that are not fully seated and locked.

These instructions apply to INTEL coolers that were shipped with pre-applied Thermal Interface Material or Thermal Interface Compound.

Without removing the cooler take a flat blade screwdriver and turn the locking pins 90-degrees counterclockwise to the unlock position. With all the locking pins loose, without lifting up on the cooler assembly "gently" turn the cooler assembly left and right a couple of times (Just a couple of degrees each way). Turn the locking pin assemblies back clockwise as far as they will go by hand, and re-align the locking pins with the holes in the motherboard. Push down HARD on 2 pins at a time diagonal from each other, until all 4 pins are fully down and locked.

If you removed the heatsink you will need to clean the heatsink and processor with high-purity isopropyl or denatured alcohol and apply new thermal compound.

Here are instructions from the Artic Silver site as to how the thermal compound should be installed. Whether you use Artic Silver or another brand of thermal compound the procedure would be the same.

After the processor cooler is fully down and locked, see if the machine will boot.
