The screen turns off when reinstalling Windows or starting the BIOS. How to fix it?

Question

Iron

Hello. I decided to reinstall Windows after half a year of use, but as soon as the first installation page appeared, the monitor went into "Sleep mode", that is, the screen went out and the light began to flash, only turning off the power helped. When you start the BIOS'a and wait a little, about a minute, the same thing happens. The system itself has time to load and there is no such problem. Tried to change the BIOS'a battery, PSU and hard drive, did not help.
Motherboard: ASRock P45DE
Processor: intel core 2 quad q8400 processor 2.66 ghz
Video card: MSI ATI Radeon HD 5830

Answer 1

Perhaps the current monitor does not want to work in the resolution in which Windows is installed.
This is somewhat strange, but it may well be, for example, for 16:9/16:10 monitors and older versions of Windows that are set hard to 4/3, which thread is 1024x768 or 800x600

Answer 2

do you have any problems with iron? swollen conders, for example - he is 100 years old at lunchtime

Answer 3

Try connecting the monitor through a different interface - for example, through vga

Answer 4

It all depends on how you install Windows, and what kind of driver it comes with!
Try:
Install from another assembly;
check the system board for problems, at least superficially examining it, if there is a tester, then go through all the main voltages;

• If there is an assembly with C PE boot install firewood and check the video system;
  
• Also Try to deploy Windows with PE and boot;
  
• Play around with video outputs;
  
• If it doesn’t help, then most likely the handkerchief is an old problem in it, there may also be a video, given that the board is from ASRock, I agree with Diman89 check the conders!
