Windows Vista black screen, and other minor errors?

I posted this on the Microsoft Windows Vista forum, but I figured I
might as well post it here.

I just purchased an HP Pavilion Notebook model dv2513nr about three
days ago.

My specs are as follows:

Microprocessor 1.6 GHz AMD Turion â„¢ 64 X2 Dual-Core Mobile Technology
TL-52
Microprocessor Cache 512KB+512KB L2 Cache
Memory 1024MB DDR2 System Memory (2 Dimm)
Video Graphics NVIDIA GeForce Go 6150 (UMA)
Hard Drive 160GB 5400RPM (SATA)

As for my problem?

I have had no problems until today. I loaded Windows Vista (32 bit),
and
after the loading bar, but before the "Welcome to Vista" screen, it
showed a
black screen with a green vertical line through it, not down the
middle but
off to the right side. The line itself was around 5-6 pixels wide. I
was told
this is a glitch in Vista, and not to worry. Anyone know about this?

Later on, I loaded Vista again, and after the "Welcome to Vista"
screen,
instead of loading my desktop, it loaded a black screen, so I reset
it, and
it still loaded the black screen. So on my third reboot, it still
loaded a
black screen. All the times I got a black screen, my keyboard and
mouse were
responding. So I pressed ctrl + alt + del, and came to a blue-green
vista
screen with several options. I clicked cancel, and it loaded my
desktop just
fine. I've had no further issues. Anyone know anything about that?

Then, I put it into hibernate, and came back with this error.

I looked it up, and I seem to not be the only one with this problem?
No one
seems to have a fix yet, so I thought I'd ask what this is about?

I sincerely hope I do not need to return my laptop, because I just
went
through hell and back with my old laptop, and that is what made me get
this
new one.

I hope it's just Vista being unstable, and nothing serious, like a
hardware
issue or something that would need my laptop to be sent off or
returned.

Any help would be grateful, thanks.
