HP Envy looses connection with WIFI

[KimberlyIsak]

I need help!

I have so many problems with this computer that I don't even know where to start..

For some time now my computer looses connection with WIFI. It takes 20 minutes from start and the WIFI disconnects. The first 10 seconds after the disconnecting I can see all the available WIFI users in the field but then everything just shuts down and I can't even search for WIFI. Every user just disapear.  I've only had the computer for a year now and the problem started after only 3 months. This did'nt disturb me at first bc I did'nt use it that much but know when I need it every day I need this to be fixed. 

The other problem I have with it is that I can't watch any videos for too long or the screen is flicker in different colors in the video. It's like it gets too hot or something and it just can't handle everything that happens in the video? This problem starts after 1h. 
One other problem is that I can't play any games. The Sims is just a big nono. The first time I tried to play the computer flipped out and showed black or blue screen. I had to turn it off bc I could'nt press anything to make it stop or to turn the game off. After trying too hard and after restarting the game too many times it started to turn it self off instead.. I had to make a adjustment in the game that makes the graphics look very bad, but that was the only thing that helped. 

I have submitted the computer to HP support one time and when I got it back they had updated the BIO system, but the problem was'nt solved so I had to call HP support. I've talked to them 2 times now in the phone and a 3rd on monday.. The first time they helped me with an update (HP connection optimiser) and helped me to uninstal the network card (Realtek). The second time (today) they helped me update the BIO system (again in one week?!?!). This did'nt work either. 
30 minutes ago my computer flipped out again and shut it self of after I connected the HDMI cable into the TV bc I was watching a show. I watched 1h and then it flipped out and the screen turned black with some green stuff on it. Then it started to make this wierd noice that it was about to blow up.. I can't even explain it.

Please help me. I really need a computer bc I'm starting to study this fall.. Sorry for my bad english I'm from Sweden 🙂
