Can'TThinkOfAName

1. So i using my computer playing a game and the whole thing shuts down randomly

2. I go to turn it back on, and it starts but then immediately turns off, like it’s trying to roll over but it doesn't have the strength to make it over the hill. It doesn't even have time for a beep code

3. So i turn it off and leave it be for a while

4. Next day I turn it on like normal and it boots normally do a memory diagnostic test.

5. Before the test finishes, the computer shuts down

6. I try to turn it on but it wont boot like in step 2.

7. I open the chassis and inspect the mobo for bulged capacitor or ny sign of damage. Perfectly fine.

8. Clean the pc.

I have a school task to make a working oven using cheap, available materials. Its a small oven like 10cm cube oven to heat 4 degrees celsius party pie to 60 degrees. The exterior will be out of wood. The question is what materials should i use to insulate the oven and trap the heat? i'm thinking of layering the inside with aluminium foil and making a gap and stuffing the spaces with cotton. Some other materials i could use are cellulose, Polyurethane Foam, styrofoam or mineral wool to keep the heat in

I've had this pc for 3 months now.

my knowledge of comps is limited. i didnt build it, a friend did it all for me.

Anyway, i was playing batman arkham origins, and suddenly the screen blue, all blue, no text or anything and there was a beeping sound. this was what i did afterwards

1. i held the power buttin down and then started it up again. the fans and lights where on but there was nothing being displayed on my monitor.

2. so i unplugged everything, pressed the satrt button 3 times, replugged everything and pressed the start button. this time the fans weren't spinning and the comp was turning on but instead the lights kept blinking slowly. weird

3. i waited a few minutes afterwards, and then began to spam the start button because i was frustrated. nothing

4. i left the room did stuff, came bak then just pressed the start button. boom. working now.

question is, wtf happened, why, and how do i keep it from happening again.
