I have an unusual problem with my home-built system. When I turn off my system, the next time I turn it on, it powers up but doesn't boot up. All the fans (CPU fan & two case fans) are spinning, as is the hard drive, but there are no beeps, no images on the screen -- nothing. I then turn it off using the power button and turn it back on, and it boots normally. If I leave it on for a day or more, as I usually do, it runs just fine - no indications of problems at all.
I've replicated this sequence -- turn off, turn on, power up but no boot, turn off, turn on, boot up -- several times. My hardware configuration is:
- AMD Athlon 64 3000+
- Gigabyte GA-K8N51GMF-9 GeForce 6100 Micro ATX Motherboard
- 4 GB Kingston ValueRAM PC3200 RAM
- Hitachi HDS722525VLAT80 250 GB Hard Drive(7200 RPM, Ultra-ATA/100)
- Integrated Nvidia GeForce 6100 (256 MB)Video
- Syba USB/FireWire Combo Card
- SoundBlaster X-Fi Xtreme Music Sound Card
- Lite-on IDE DVD/CD-RW
- Iomega Internal 250MB Zip Drive
- Sony Diskette Drive
- Antec Case w/ two 120mm case fans (front and rear)
- Antec NeoPower 480w power supply
- Windows XP Pro w/SP2
I don't think it's a power issue. My Antec NeoPower 480 worked fine with my old motherboard, and I had a lot more separate peripherals, including a FireWire card and ATI X700 Pro video card, each of which required separate power connections.
I downloaded the latest BIOS update and drivers for my motherboard, so I'm not certain that's the issue, either. As I indicated previously, it runs just fine once it boots up.
If anyone can unravel this mystery, you'd be helping me immensely. Thanks!
