Question : Running XP Home Edition w/SP 1a.  Problem with search screen/windows explorer.  Search screen turns on unbidden.

I have a ABS computer (custom made).  3.0 MHz Pentium, 1024 MB memory, ATI 9800 XT graphics, Audigy 2 ZX sound, RAID 2-0 (Western Digital 120 MB HD's), ASUS motherboard.  It's running Windows XP Home with SPD 1a (plus updates).  Ever since I've had it, a maddening problem has occurred (motherboard and HD's have been replaced).  After boot up, the Search Screen (on Start Menu) comes up unbidden and begins iteration after interation.  I sometimes see 50-60 Windows Explorer groups in the task bar.  I try to cancel these out using Task Manager, but it's usually a losing proposition.  I know this sounds weird, but this problem seem to occur most often in the afternoon -- after the machine sits all day.  It usually runs fine in the morning.  Also, it sometimes won't boot properly.  The HD light stays on until I press FI, and the Windows splash screen stays on until I press Control several times.  I've reinstalled Windows from the image on my HD twice, but it doesn't help.   This is obviously a game oriented machine, and it runs beautifully -- when it runs properly.  Benchmarks are right up there.  I can't seem to find any references to this problem in the databases I've checked.
