My Photoshop is being very strange....

I am currently using (it hasn't changed since last time xD) PS 7.0, for... iunno a few months now & I've never come across a problem like this. The scratch disks are one thing but this... it's really strange.

I had Photoshop open, but my internet decided to be all funky and kind of froze so I restarted. I didn't open PS again until a little later, from what I recall it worked just fine but I THINK I switched the power switch off while it(the computer + PS) was on. Didn't think much of it, I always do that when something funky happens. I tried to open PS and what happened was this:
It started up just fine but when it finished checking for everything it just vanished from my taskbar & didn't even open. No message of what was wrong, no nothing.

I restarted my computer, I reinstalled it, I even went through ImageReady, it just won't open. ImageReady will... but PS is just being all funky.

Maybe I messed it up with all the ons and offs? Iunno.... I'm smart with computers when you compare me to my family but on this kinda stuff.... I'm clueless.
Any help is greatly appreciated btw :)
