Vista - Odd Boot In Safe Mode, Freezes w/ Normal Boot

I was playing a shockwave game on my computer while being extremely lazy, and apparently the housework Gods have decided to punish me.

The Vista laptop was unplugged, running off a battery, and ran out of power.

I plugged it back in, but it wouldn't restart until I unplugged it and took out the battery for a minute.

It then gave me a blackscreen that said it needed to check its disc, so I allowed it to do so. I wandered away from it, and when I came back the "Users" screen was up. But it was frozen, so I rebooted (hard boot required)....

THe next time I was able to get into my User Account, but it froze while loading my anti-virus software.

So, I rebooted, and it ran the whole CHKDSK routine again, and it froze at the user screen.

SO, I rebooted again, this time in safe mode, and it froze at the user screen.

So, I rebooted again, and again in Safe Mode, and made it into my User Account this time.

What should I do now?
