hp 3005pr usb 3.0 port replicator crash several times a day

[csoapy]

To James,
if i switch to Win8 on same system(hardware), it never halt but still would freeze awhile sometime on several last release version.

i installed lastest driver 7.4 M0，there are somthing different from old driver(7.1 ~ 7.3), yes since 7.1, i install every released driver.

firstly, sometime, XP would pause responsing of display and keyborad & mouse input, that's means freezing awhile. but other time, XP halt, becase all lamps but power on my pc would close. BTW, if i play music through my dock, it would freeze or halt mostly after installing 7.4 M0.


and another question, how many valtages on power input? i checked this document(http://h18000.www1.hp.com/products/q...a/13223_na.PDF), and found that value is 19.5V! same as my notebook's power adapter. dos it need such large power? i now use an power adapter with 12V 4A output, maybe this is why it crash frequently?
