After putting all components together PC started without any problems. PC was connected through HDMI to external monitor (grafic card port). In BIOS I’ve enabled PS2 emulation to be able to use mice and keyboard. Then I set boot from DVD. Windows has been installed and was working successfully. I wanted to install driver for grafic card, which wasn’t working (but was connected). As I didn’t have CD with driver, wireless adapter , LAN cable , I turn the PC off.
After I bought USB wireless adapter, I connected it through USB. After turning on the PC my monitor stayed black with title “no connection (no source)”. HDMI cabel as well as monitor I’ve tested by connecting them to my laptop and everthing worked. The I tried to connect monitor (through HDMI) to mother board port and grafics port, nothing worked, just black screen. I do not have DVI cabel, VGA ports are not available. Then I disconnected USB wirelless card. I took away grafic card and reseted CMOS. HDMI cabel was reconnected to mother board and turned PC on. Monitor shows data now, but doesn’t run WIN7 from SSD drive, and doesn’t boot from DVD. It shows only black screen with with cursor. I am able to go into BIOS.
Could you please advise what to do in this situation ?

Since you have a display in the BIOS it sounds like a crashed OS.

Not that you have to tell but the last few months has had a few cracked pirate Windows 7 OSes show up at the counter which were "not booting." Installing a fresh OS (not pirate) cleared them all up. About half the clients don't want to pay for the OS and they take the machine back.

Hi, thank you for your comment. It is an original Win7 installation medium.

At the moment I am downloading Win10 through microsoft tool to test if system would work at newer platform.
It may also be broken SSD drive. In the meantime I've tried to remove SSD and tried to boot from DVD, which was working. After connecting SSD back, the same issue persists (being stuck at black screen with cursor)

That makes me think of fast boot options.

Look around the BIOS for fast boot options (note! not always called the same thing) and turn them off.

update

this function has been disabled (no effect)

But, I have an update. I've tried to download WIN10 through official MS tool and boot was successful. I did SSD disc formatting, and installed new OS.

I've reconnected grafics card, installed the latest driver. Now I have another problem.
Is it normal that grafics fan starts after PC is turned on, and in moment when desktop appears, fan stops ? Is it because of some 'energy saving mode", and it is enabled only when needed, or this is malfunctioning ? I just add that the latest driver has been installed. Is there any way how to do testing ? I've tried to run FIFA 15 demo and fan did not start.

I appreciate all comments

YES. That's normal.

It's on the web so my short (excuse me for being short on this) explainer.

Since the fan control is via the drivers the design decision is to max or close to max out the fan speed until the driver gets on its feet to take a temp reading and set the fan speed to what's needed. Just in case the card was at a high temp at boot time.

There are debates (which I won't start) about if this should be done like this.

Thank you for your comment. I've done testing by using unigine heaven and it started working so suppose it operates as it should
