Not sure about the other things you added in your post. Is the system working well other than this Flash problem? If so I will the rest there and concentrate on the Flash install problem. If not, perhaps make another thread and detail the other problems?
I would use Adobe's dedicated Flash Player Uninstaller from;
Download that uninstaller file to your Desktop, then run it. it should uninstall all Flash products from the system.
Then I would reboot, (restart), Windows, just to ensure the registry and any system files have been updated.
Next step, back to Adobe to install Flash, from here;
Beware! Look at that web page carefully because Adobe has included an option, (top right of the page), for downloading and installing a McAfee security installer. You may see a different option in your browser. If you don't want that additional utility, remove the tick.
Then download the Flash installer to your Desktop and run it.
See if that works.

Firstly I want to say this computer has not been turned on in more then a year. Family that got it off me said it didn't work... That it just beeped and shut off...only thing that looked wrong to me today at a glance was that little switch in the back was set to 230 and not 115 so I flipped it back to 115 and up until now it seemed to work fine and as fast and noisy as I remember (it's pretty big and I think a counted 12 or 13 fans in it once)...according to the guy I got it from when he "upgraded" to some sort of water cooled system or something (actually I think he just dropped parts in a vat of oil *shrugs*), he said, that this is running hot. the little readout next to those knobs to control the fan speeds are reading from 58 F, 120.8 F and 88.2...but I know my body temperature is in the 90's and the internal air feels moderate while the shell that it is all in is cold to the touch...I do not know if that could have anything to do with my actually problem.
The above only mentioned as a possible part of the problem?...figured I should be descriptive to a fault rather then vague.
Its odd where my knowledge about computers abruptly stops and starts again...but any way, the problem I am having right now, is while trying to update...well everything security and Internet related that isn't necessarily automatic.
I get the following error when attempting to install the latest version of the adobe flash player (downloading installer step):
Installation is corrupt! (16291.103.506 - 42072312.80040154.FFFFFFFF.80040254)
