Windows task bar is on top of full screen video or games

Windows 10 task bar is on top of full screen video or games.

This happened to me recently. I could not figure it out for a while, there are all sorts of "fixes" on the internet about it.

I got a clue that reminded me that I had changed the resolution of one of my monitors to something other than normal, and back again. restarting explorer did not fix the issue. I logged off and back on again and now it is back to normal.

Hum in class D Sure Amplifier

I have a Sure 2 X 100Watt Dual Channel Class D HiFi Power Audio Amplifier Board - AA-AB32971 that I built as an amplifier for my computer.

I was having trouble with hum especially when the LED lights in my laundry room were turned on, or the wife ran a vacuum cleaner in the back room.

Also sometimes for no apparent reason I would just get hum at anything above low volume settings.

I tried line conditioners, filters, different outlets, ups's, audio isolation transformers, different connectors, and ferrite loops. Nothing would stop or reduce the hum. The audio isolation transformer would inject a local AM station directly in to the amp.

The power supply was a switching supply taken from an old laptop.

what fixed it was installing a 3 prong to 2 prong adapter on the plug. The lack of ground on the plug caused the problem to stop.

How to make your own Vanish or SaniFlush crystals

Sometime around 2009 the government banned Vanish and Sani-flush because it contained Sodium Bisulfate. 

The crap it has been replaced with is terrible at cleaning toilets and removing hard water stains. 

It also had the effect of helping to keep older toilets flushing because it dissolved calcium buildup in the jet hole.

use this information at your own risk.

You can't get real Vanish or Sani-flush but you can get the main ingredient that they used.

Just go to a pool supply store and buy Ph- but make sure it says on it sodium bisulfate or sodium hydrogen sulphate.

keep in mind this is pool acid and don't handle the crystals.

place 1/2 cup sodium bisulfate in the toilet bowl let it sit a few minutes and stir it with the bowl brush. wait 15 minutes or longer then scrub as normal. Sodium bisulfate does not fizz or bubble like the original vanish or sani flush because the bubble were for show they did nothing other than neutralize some of the acid made when the crystals dissolved in water.

The remainder of the ingredients was a surfactant (sodium lauryl sulfate), blue dye, and wintergreen scent. Only the sodium bisulfate did anything.

I use it all the time now.
