What is the problem with my new computer? Help please?

I recently bought a new desktop. The specs are
intel core i5 2500k
corsair 8gb
asus 6950 2gb direct cu 2
asus p8p67
wd 1tb
cooler master haf 932
cooler master 700w psu
twinguard microtek 1kva ups
acer 20" led

One day i noticed some kind of black smoke coming from the front of my case, I shunt down the computer immediately then. I opened the case and check the inside of my case i didn't find anything wrong and i am not a pro.After some time I started the computer and nothing happened. Later i played crysis 2 for about 5 hours and nothing happened. The temperature of my gpu was 45c after playing crysis as showed by asus smartdoctor and idle temp of gpu is 37c. Idle temp of my cpu is 40c and of motherboard is 32c shown in asus ai suit. I am using the stoke cooler for mu processor. Yesterday i ran a torture test in prime95 (in blend mode) about 1-2 hours and noted my cpu temperature as 46c and motherboard temperature as 37c. Still no presence of black smoke again. The room temperature is about 22c in my house. Now please tell me is there any problem with my computer, i am a little worried. Also any useful information's and tips are welcome. Thank you.

Well presumably if there was smoke then something burned out and probably won't be working now. Just check to see if everything is working, even down to minor things like case lights and extra fans etc.

I wouldn't worry about it too much if everything is working though, it might not have even been to do with your computer since everything works now and it was coming out of the front of your case. Reason being that it doesn't make a lot of sense since the front of your case would suck in the smoke if anything.

Now there seems to be a new problem. When the computer is running in battery(ups) power there is strange buzzing sound coming from the case, I only noticed it now because the electricity was gone a few minutes before and the sound suddenly started. I am feel foolish because i never thought of checking it before. There is no sound when the computer is running normally.
