strange system reboot problem

hi, all,

I have a strange system reboot problem. Please help me out.

Every time I reboot my pc, windows (xp pro sp2) couldn't start up. PC always says," disk boot failure, insert system disk and press enter." i pressed enter, but the alert still comes up and windows could not boot up. However, when i turn on my pc, the problem won't show up. i could log into windows immediately. In other words, the problem only happens when i restart windows.

I have checked the disk cable already. the connection is fine. the booting order in bios is cd-rom, floppy and hard disk. but there is nothing in the first two devices.

my system is clean with windows patches only and i just installed it. there is no virus inside.

i built my system three months ago( so i don't think it would be a battery problem)---AMD sempron 2500+(no overclock), kingston pc3200 ddr 1g, gigabyte GA-K8U(bios version F6), western digital WD-800JD(it is a sata HD, but i set it as an IDE in the bios).

any ideas or comments?

best regards,

shek

 

Um probably not this. But since your boot order is cd-rom, floppy and hard disk. Are the cd-rom & floppy drawers empty?

 

yes, they are empty.

btw, even there is a boot failure during the restart, the system does detect my HD on its self test.

best regards,

It could be a HD-problem.

Perform a extended test with Western Digital's Data Lifeguard Diagnostic.
