Windows 10: PC loses signal to display, and does not respond

Hi, my PC will lose signal to display but keep running, as the fan gets loud but the computer is not responsive as i disconnect from everything. It started when opening heavy games, and evolved to barely being able to make it past the log in screen without the fans blowing harder and losing signal to display. I have tried upgrading the power supply but the problem persist. In the beginning i would also get glitches on the display after a crash, but would be fixed quickly by a restart. that doesnt happen anymore. I have noticed when the crashes happen, on my graphics card Rtx 2060, lights

No Signal on the extended display

Need your help, google didn't help.
Short description:
No signal on the extended display
Laptop: Dell xps15 9570
OS: Windows 10
Display: Philips 245E
Details:

• connection - HDMI
  
• it was working before, but nothing has changed, after a few days of being turned off just stopped working
  
• display is detected by the laptop, I can see it in Display settings. But "no signal" on the actual display.
  
• Speccy link: http://speccy.piriform.com/results/80vYxevPHSAuYLWTKoLb5Kd
  

I am 100% sure that this is a software issue with Windows.

What have I tried:

• plugin another laptop to my display - it worked. The display is working fine with other laptops
  
• plugin another display to my laptop - it worked. I tried to connect my laptop to a TV using the same HDMI port - it worked
  
• switch HDMI cables - no result. HDMI cables seem to be fine
  
• reinstall display, and video adapter drivers - no result
  
• tried different modes ( extend, duplicate, only pc, only extended ) - the same situation in all modes, display is detected but "no signal"
  
• I have booted from a USB stick (Ubuntu) and the display worked without any issues
  

 

N70 losing signal

This is really annoying me now. I've had an N70 on TMobile for two weeks and it freezes and loses the signal almost every day. It fails to work in any of the areas where my old Nokia used too. TMobile suggested forcing GSM through the Settings>Network
menu and this fixed it...for one day! Now back to square one with phone losing signal for hours on end wuith no warning, not being able to make or receive calls or text in the middle of a city is a nightmare! Any ideas what to do? Change the phone?
