explorer errors, program errors, no task manager

[Guest]

New Sony laptop w/ Vista Home Premium has problems. At least once a day my
explorer windows will open and be blank, and I can't fix it without
rebooting. Also, about once a day, some program will cause an error and
close, but there's no rhyme or reason to which program it happens to.
Lastly, when all this happens and anything is frozen, I can tell it to open
task manager, but nothing happens. Any ideas? Stupid Sony told me to
optimize my startup and display settings. Not suprisingly, that did
nothing...

Unfortunately I can't return it, as much as I wish I could. Also, it didn't
come with a regular installation DVD, and even the OEM install stuff isn't on
a CD either. I'm going to try to search Sony's tech support stuff about
doing a repair install, see if they hid the files somewhere on my computer
already. Any ideas?
Thanks for the advice!
