OT computer crew, got a problem for ya... today while i was watching tv, my laptop screen goes black. i turn itoff, then back on, for it to do the startup screen, then it went to a blue screen (bsod?). on the screen it says there was a fatal error in the windows logon process. it had two codes on the screen: c0000219 and 0xc0000135. what does all this stuff mean? did the hd crap out, or is it something more serious? laptop is a dell inspiron 9100, p4 w/hyperthreading, 1gb ram,xp home os w/sp2.
