Computer won't POST / Boot

[moforles]

Hi everyone. My new system has been running fine for a couple of weeks, but a few days ago, I tried to boot it up, and all of the fans/lights turned on for a few seconds and then all turned off. Then they turned on again and turned off. The process repeated until I finally turned off the power supply. Now this happens every time I attempt to boot the system.

Here's the build:

Intel Core 2 Quad Q6600 Kentsfield 2.4GHz 2 x 4MB L2 Cache LGA 775
GIGABYTE GA-P35C-DS3R LGA 775 Intel P35 ATX Intel Motherboard
2 x CORSAIR TWIN2X2048-8500C5D
eVGA NVIDIA GeForce 8600GTS 256MB GDDR3
Samsung SpinPoint HD501LJ 500GB
ASUS DRW-1814BLT (Black 18X DVD+R ?)
Windows Vista Home Premium 64-bit (OEM)


I've read that others have had similar problems. Would replacing the motherboard be the best step? What about replacing the power supply?

Thanks!

Hi moforles,

I have had problems with a couple of other Gigabyte MBs where similar things happened. In most cases, the motherboard was the culprit. In one case, the video card and power supply were also damaged. Each time, this happened using a case that had neon fans/lights. Don't know if there's any connection to the lights or not.

The best test would be to test all of the major components in another system if possible. Especially the video card, hard drive, power supply. Maybe the RAM and CPU.

Another good test would be to see if the system will POST with the motherboard out of the box and just the CPU, one stick of RAM and video. If it does start, it will yell at you for there not being any drives, but it's OK for a test.

Good luck. Let us know what you find.

Hi moforles,

In most cases a quick reboot in the initial stages of the POST indicates that the CPU fan is not starting, not spinning up to speed, or is not well seated and pasted on the CPU.

Open the case and give it a look, don't depend on just hearing fans start up to assume that they are all working <G>.
