I'm inclined to think this might be my power supply or motherboard going bad, but I'd like some thoughts.
Here are my system specs:
ASUS A7N8X rev2.0 Deluxe motherboard
AMD Athlon XP 3200+ processor
1024MB PC3200 Corsair RAM
ATI Radeon 9700 Pro (128MB) AGP
2x120GB Seagate SATA drives in RAID-0 configuration
Plextor 8x DVD-R/+R/RW/etc.
Antec Sonata case with 380 Watt power supply
On initial bootup in the morning about five days ago, the system POSTed fine and then hung at the Silicon Image RAID initialization screen. It wouldn't detect the harddrives in the RAID array. After a warm reboot (I hit the reset button), it detected them just fine and then booted to Windows normally. I ran all sorts of system diagnostics in Windows XP Pro, but they didn't seem to detect anything wrong with the harddrives themselves.
This pattern continued for about three days -- cold boot failing to initialize RAID followed by a successful initialization and boot to Windows XP after a manual reset.
Then yesterday morning, I turned on the computer and it wouldn't even power up to the POST. Everything would light up, but the harddrives wouldn't spin. Hitting the reset button or the on/off switch did nothing here, so I had to turn off the power at the power supply. Once I turned it on again and did a cold boot, the system POSTed fine (although I had to reset the CPU speed), and then proceeded to the RAID initialization with similar results as before. After a warm reboot, the system would POST and initialize the RAID array and launch Windows XP. It did the same thing this morning as well.
Thoughts? I'm disturbed that this appears to be getting progressively worse. At this point, I'm inclined to just keep the computer on continuously until I can figure out what the problem is and fix it.
Thanks!
