Real Life Horror – Windows Unable to Start or My Misadventures in Hubbing

I own a laptop which operates Windows 7. It has two USB ports, far less than what I require. Frustrated with swapping devices in and out and trying to get them recognized, I purchased a ten port hub on eBay, which arrived yesterday. I liked the wall mounting option because of my small desk area. And the price.
I unwrapped it and plugged it into the powerstrip and connected my keyboard, mouse, printer, and then laptop via its special cord.
The horror begins.
My HP went black screen of nothingness. Needless to say, I unhooked everything and began to act like I was locking up inside myself. All the work I have done and failed to back up raced through my mind like the matrix green and black screen on speed. My brain began to overheat. Three keys glowed on the laptops keyboard, but no startup. I turned it off and began my plans for panic attack.
After my boyfriend – hereby known as Magic Finger of Hope – pushed the power button, it finally spit out something about thermal hibernation. We let it power down and set to cool.
I read reviews on Amazon (post purchase of USB hub) to find out that it A)Does not support Windows 7 and B) Can possibly BACKFEED POWER.
Oh good. Backfeed as in distributing power to things that do not need it. Maybe that was why the battery was acting as nuclear reactor. I might be dramatizing a bit. Only a bit.
Hot lil laptop plus writer deadlines plus Meri equals you-haven’t-seen-crazy-yet-beeches.
So, I am in “this may take several minutes” stage of startup repair mode. Oh, dear Lord please save my files.
For all of you readers (all seven of you) DO read reviews BEFORE you purchase anything that connects to the multihundred dollar device of your favor. Just do.
Oh my God. A new screen. Let’s hope it doesn’t contain the word fail!

Okay, recovery process has begun. File backup first, then restore. Wish me luck, loyal fans!
