Dude!
I did not quote you, but you received email notification of my reply, yes?
It is preferred "form" here to use edit rather than reply to your own notes.
So... Let's see if I am starting to get the picture.
Anyways I hit F1 at restart to play with settings.
You used F1 to adjust your BIOS settings. Now, your computer is fubar... Hence the warning often seen...
Making changes to BIOS settings can have adverse effects on the way a computer performs. Use caution when performing BIOS modifications.
It is probable that we can restore your BIOS settings to factory default but, to do so, we need more information.
Tell us details about your computer...
Mainboard - Make and Model
Processor
RAM
Cards installed
PSU
OS = XP (Home? 64? also including SP if applicable).
(not essential at this point, but likely will become important soon)
(Adjust the above as needed for a laptop!)
Finally, if your initial issues are due to virus, BIOS settings are not going to be any help to you.
Once we have you restored to the point you can see your monitor, and hopefully boot to safe mode,
we will need for you to go to the Virus and Malware area,

read the three stickies at the top, and if you decide to clean rather than follow the other Sage Advice, then
following the 8 steps scrupulously,
https://www.techspot.com/community/...lware-removal-preliminary-instructions.58138/
start your own thread there asking for help to get cleaned up.
I would recommend that you read some more here before you do so, so that you minimize your chance of getting ignored or "dissed".
In particular I would recommend the tutorial by Kimsland...

Finally, remember that everyone here generously donates their time and expertise in order to be of assistance.
Many (most?) you encounter here in one way or another do Tech Support professionally.
For me, it is just a hobby.
Several dozen people have already looked at your post here, and if I am not able to help you to at least get your monitor back, one of them likely will.
