Vista Ultimate x64 services timeout issue...

I recently installed Ultimate x64 which ahas been running fine. I hav
noticed a couple times when I come home from work my computer reboote
and it lists it being due to a bluescreen. I search through the Even
Viewer and find that several services have time out like the following

\"a timeout (30000 milliseconds) was reached while waiting for
transaction response from the audioendpointbuilder service.\

\"a timeout (30000 milliseconds) was reached while waiting for
transaction response from the cscservice service.\

\
a timeout (30000 milliseconds) was reached while waiting for
transaction response from the hidserv service.\

i am not sure what is causing these. i know i can edit the timeou
limit in the registry. however a couple of these do not have entries an
the ms article tells you to make a dword. i know in x64 you have qword
with are x64 entries. one, would that even be a fix and two, would
still use the dwords or would i do the same thing but with the qwor
entries
