Why does my A/C Compressor keep going bad?

In mid August, I changed the A/C compressor in my 2003 Honda Civic EX because it was making a horendous screeching noise every time I turned on the A/C and eventually, cold air stopped coming out. A couple of days ago, my car started making the same screeching noise when I turned on my A/C. Why does my A/C compressor keeping going bad? Is there a different part in my car the could be causing my compressor to fail?

What causes thick-mashed potato like substance on/in a radiator?

I picked up a free car, it's a 2002 Honda Civic that he said needed a head gasket. (He doesn't know ANYTHING about cars) all he said was that it overheated and just googled and of course everyone says head gaskets.

I brought it home, checked the fluids and nothing is mixed. Oil is just oil, coolant is nasty dirty, but just coolant. I put about 3/4 gallon of water in the radiator to top it off and the car runs and drives just fine. Didn't ever get past halfway on the temp gauge, heat works great, AC works great as well.

The only thing I noticed odd, was this thick white paste looking stuff that seemed like it boiled over or something out of the radiator. I've saw milky oil and coolant before, this is nothing like that. It's literally thick and gritty like mashed potatoes or something. I'm gonna do a flush with the radiator cleaner stuff and replace the radiator cap off the bat, but I'm just curious what that stuff could be?

My car won't stop beeping

I have a 1990 Honda Civic I've had it for 4 years. First some background info on the beeping. When you turn the car off and leave the key in the ignition the car beeps and won't stop until you take the key out of the ignition. It's a simple 4 quick beeps about one second long occurring every other second. I assume it's a feature that prevents you from leaving your keys in the ignition. Cool makes sense. Ok so here s the problem. About 4 months ago it started doing that same beeping but not when the car was off and the key was left in the ignition but when I was driving. It would beep a few times then stop. It was a very occasional thing. Over the next 3 months the beeping happened more frequently and stayed beeping longer and finally about a month ago the beeping started every time I turn the car on and continues until I turn it off and remove the key. Over this month I've just turned the music up loud enough to mask the beeps but it's a really loud annoying beep. I just want it to stop. Today while trying to figure out how to stop the beeping I discovered that if I open the driver door it stops. If the car is off and the key is in the ignition and beeping if I open the door the beeps stop but as soon as I close it they start again. Same with if the car is in accessory mode beeping away if I open the driver door suddenly the beeps stop but as soon as the door closes they start up again. Same if the car is running.

BMW X5 vs Honda Civic as a first car?

I'm getting my first car soon and I'm 17 going to college next year, Honda Civic would be the better option I'm guessing if I'm paying for my gas and insurance myself, but the bmw is sort of fuel efficient w just a 7 mpg difference and nicer, would I be delusional to assume that I could keep up with the expenses of a bmw without any help from my parents? (not paying for the car myself)

Should I replace timing belt on 04 Honda Civic that I just purchased?

Should I replace timing belt on 04 Honda Civic that I just purchased? - 1

Added (1). I bought an 04 Civic with 123k on it. The dealer doesn't know if the TB was replaced but said his mechanic thinks it "looks" fine. My co-worker insists that if the car has made it to 123k without the TB breaking that it must have been replaced, and thinks I should risk not replacing it right now. Does that seem like a reasonable assumption? Just want to get some opinions, I know I might just have to replace it for peace of mind anyways.

Is it the car timing? 2000 Honda Civic LX?

On Tuesday, I was pulling in to the driveway when I noticed that my car temperature was going up towards the hot. But as I pressed on gas it went back to the normal in between hot and cold. On Wednesday, I drove a far distance and I noticed my car temperature went all the way up past the hot red Mark. Then the white smoke came from under the hood. I pulled over and it was smoke around the engine. We put water on the car and antifreeze. But it poured out on the left side of the front. The mechanic came and said it was the water pump and the timing belts. He replaced them and the car was good. Then as I'm driving the car it feels like it cut off for 1 second and cut back on. It does it while I'm driving and it's worse when I stop.

Do I need to fix the TPSM light on my 2011 Honda Civic, or can I leave it for now?

It is NOT the tire pressure light (the!). I assume it means one of the sensors are not working, or the system isn't working. I checked my tire pressure and they are all fine. I have no time to bring it to my local mechanic. Can I leave it for now and just check my tire pressure periodically, and bring in the car when I have the time?

Added (1). No reset procedure, I can't ignore it indefinitely because I will need an emission test soon and they won't pass if the light is on.
