I am trying to build a pc from a motherboard and intel processor that I bought awhile back through the Intel Retail's Edge Program. I put the motherboard (Intel® Desktop Board DG965WH ) and the processor in (Intel® Core™ 2 Duo Processor E6300) in to the case (which I also bought new.) After troubleshooting different problems, I finally got the (heatsink fan) to turn on.However, it seemed that there was no video signal going to the monitor (I have a separate video card, but I was using the built-in VGA output.) and now...sometimes, when I turn it on, the heatsink fan turns on for a couple of seconds and then the fan shuts off. any ideas on what it might be?

Short diagnostic summary for the Intel Desktop Board DG965WH + Core 2 Duo E6300 build: the fan coming on briefly then stopping and no video can be narrowed down without buying parts first. The hints from , and point to power, boot configuration and cooling. The following prioritized, safe checks isolate the fault in a few inexpensive steps.

  1. Safety and bench setup — disconnect mains, ground yourself, remove the board from the case and lay it on a nonconductive surface.
  2. Minimal-boot configuration — attach only the PSU (24‑pin) and CPU 4‑pin/8‑pin, one known-good RAM stick, CPU cooler (with its fan header plugged into CPU_FAN) and either the onboard VGA or a known-good GPU. Leave out HDDs, optical drives and extra cards.
  3. Power verification — use a PSU tester or a known-good PSU. If neither is available, a careful paperclip test can show whether the PSU spins, but swapping in a working PSU is safer and more diagnostic. If the PSU runs but the board still shuts itself off quickly, look for shorts (incorrect standoffs, foreign metal) or a motherboard protection trip. Inspect for bulging caps or burn marks.
  4. POST, speaker and CMOS — connect a small chassis speaker for beep codes, and clear CMOS to rule out bad BIOS settings. No beeps with minimal hardware points strongly at power/motherboard/CPU-level faults.
  5. CPU/heatsink and memory checks — remove the heatsink, reseat the CPU and inspect the socket for bent pins (LGA sockets have pins on the board). Clean and reapply thermal paste correctly and confirm the cooler is mounted firmly but not over-torqued. Test each RAM stick in the primary slot.

If these steps still don’t produce sustained POST, swapping in a confirmed-good PSU is the most cost-effective next diagnostic; a working PSU rules the supply out and focuses attention on the board or CPU. These instructions expand on points raised earlier and are intended to produce a clear pass/fail for each major subsystem before replacement.

Bad connection to mobo from PSU and/or PSU failing and/or already dead.

About $250 to $300!

Yeah dead PSU
Or you cooked the CPU

ohhh..u might not have installed properly the heat sink of u'r processor..try to fix properly the heat sink..if still doesn't work then u'r processor might have some problem..

If the CPU is damaged, there's no fix other than replacement, not usually considered Warranty.
