A blackout will not short your PSU. It won't short anything, the only problem it may cause to your computer is if it's on, your software might be upset at being powered off unexpectedly. Brownouts are similar, except that it may not strain your software, but everything will slow down (hardware-wise). It's possible that it could cause damage, but very unlikely.
The real damage comes from power surges. This is why surge protectors are huge business. Aside from expanding your power ports (probably the main reason why people get them), it guards against those surges. I live in an area where lightning occurs frequently, and I lost about three dial-up modems to power surges. The reason wasn't from the power lines, though, but (I suspect) from the phone line, which I did not have wired through a surge protector. Keep every electronic that you can behind a surge protector. But a surge protector will not guard against blackouts, nor will blackouts cause damage. If you're having issues with blackouts, get a UPC (uninterruptible power supply). It's basically a big old battery, and depending on its power rating it can keep your system going for another 15 minutes before shutting it down. Its real use comes if you're in an area that experiences brief blackouts/brownouts at high frequency.

Yes, that's their purpose, to provide electricity to the computer in the event the mains go offline.
Most UPSs come with software that monitors the UPS. You can configure the software to shut the PC down after a period of power loss, say five or ten minutes. That way the PC can be turned off gracefully.

Well it depends on the UPS itself (the battery capacity) and your computer loads. If you're running heavy loads on your computer while using UPS it won't last long (mine can only stands for around 4min) but if you're just idling, or doing minor tasks it can last even longer...

To expand on what furuno said, it depends on two things: the rating of the battery (some batteries have a higher capacity than others), and the power draw of your system. If you're playing a hard-core game and your system is a Pentium 4, you're going to eat through your UPS very quickly. If you have a low-power system, it'll last much longer.
It's really no different than a laptop, really. Why do some laptops have better battery life than others? Energy efficiency. This is a battery, but for your main computer. On top of considering all of your system's power draw, you may also want to consider your monitor. If you look at the power ratings of a UPS unit and see what the time estimates are, they usually make an estimate based off of your computer's PSU and (for some) what type of monitor you're using. LCDs use less power than CRTs, but larger monitors draw more power than smaller ones. The UPS should only support your computer and possibly your monitor. Speakers and other extraneous devices (printer, etc.) shouldn't be used with it, unless they're absolutely critical components. The point of the PSU isn't to let you play around while the power's out, but to keep your system up long enough to be shut down gracefully, as SeijiSensei said.

I don't think that brands are terribly important. For surge protectors I buy APC and Belkin, but those are the two that are usually available to me. For UPC units, I've only really seen APC. Note that UPS units can get pretty pricey, especially if you want a very high-capacity one.

But yeah, that flickering can mean an old monitor. I have an old one thrown around somewhere that used to do something similar, too, whenever the screen was filled with a lot of white.

Anyway, if that's the case, my old monitor have something similiar like this, i've repaired it but it wasn't last long (just around 1 week), so i think buying a new one is much efficient.

When you say black page do mean not to connect it to the VGA just in test mode??
@hobbes_fan Question regarding upgrading...Well lets say I got the dvd burner and rom and the 7300gt/gs VGA and finally the internal card reader? Can I still ad fans? a big one on the side and a small one at the back? because I know with that much equipment the pc will burn up.. With a fan with this size at the side. Spoiler:
