恐怖的藍畫面!!

大大...這件事情我是過各種方法....都不能解決...
問題如下：
我重灌windows XP...格式化是用XP光碟直接格式化
然後檔案複製完畢，從新開機，到XP跑馬燈那裡，出現了
恐怖的"藍畫面"....藍畫面的內如如下:
A problem has been detected and windows has been shut down
to prevent damage

UNMOUNTABLE_BOOT_VOLUME

If thisthe first time you've seen this stop error screen, restar
your computer . If this screen appears again,follow these steps:
check to make sure any hardware or software properly installed.

If this is a new installation , ask your hardware or software manufacturer for any windows updates you might need.

If problems contiune , disable or remove any newly installed
hardware or software. Disable BIOS memory options such as
caching or shawdowing.

IF you need to use safe mode to remove or disable computers
restar your computer , press F8 to select Advanced.starup
options, and then select sofe mode

(亂碼....)

stop:0x000000ED(817E97E0,0xc0000185,0x00000000,0x00000000)

從開機好幾次了...也還是一樣...
然後我用98開機片format c: 到100%的時候....
竟然出現一個警告視窗..."wareing".....>"<...
第一次看DOS出現警告視窗....>"<....
好奇怪喔...每次到跑馬燈那裡...就出現恐怖藍畫面了....
我用了很久...還是用不好....是硬碟的關係嗎?...
藍畫面出現後...我有用XP的光碟開機...到要選要灌哪一槽...
那個C槽的格式竟然是:無法辨識...明明已經格式化成FAT32了...
竟然還....

組態如下：
光碟：windows XP (sp1)
CPU：ＡＭＤ 杜龍(tm) 650Mzh
硬碟：Seagate80G
記憶體：256 SD RAM
主機板：A open...(當初的套裝電腦)....

問題很長...謝謝各位大大看完...^^
