Windows 10: Computer is Freaking out

I have a dell inspiron pc that ive had for 3 years and only a couple weeks ago did thid problem arise. I had brought it in for a virus clean up but after running several detection softwears at many diffrent times, no virus was found. What first happens is it will start typing randomly using the 8 6 - = charicters, then it will randomly open programs that are already installed like the print function if im on a website. It will also open the magnafier as well as the search function and anything else on the task bar. All the while muting and lowering the volume and disabling the delete key.

Normally if i let it sit for a while it goes away, but it always returns and i have no idea how to stop it.

How Does This Power Supply Look?

Raidmax is a bad idea, especially if you're wanting to reliably run an 8800GT. The Antec freak listed is great deal! Only if you're willing to take the bite of the MIR's, the Corsair or PCP&C for $80 are a step better.

Does this computer build have compatibility problems? Opinions welcomed!

Lets start with what you're going to use this computer for, not what you want to put in it.

Rules/steps to building a computer (in chronological order):
First rule: Determine what your needs are.
Second rule: Define your budget.
Third rule: Pick parts.
Fourth rule: Review parts several times.
Fifth rule: Buy said parts.
Sixth rule: Build it.

You are on rule/step 1. Go through the list until you're done.
