|Tell us the make and model of your brand name system, or if you have a generic desktop system, the make and model of the mboard. |
The model, sometimes the make, of a mboard in a generic desktop system is usually printed on the mboard's surface in obvious larger characters, often between the slots.
The specific model of a brand name system is often shown on a label on the outside of the case somewhere, or it can often be determined by going to the brand name's web site and loading a program they have available, if Windows is still working, on the subject computer.
If this is a desktop computer, is there more than one physical hard drive installed ?
Go into your mboard's bios Setup while booting the computer.
Are the time and date the correct current time and date ?
If NO, the bios Setup settings have been set to defaults including the time and date, probably because your Cmos battery is too weak or dead.
You must replace it. The + on the top of the battery must be visible when it has been installed.
After you have replaced it, the first time you boot the computer, you will see an error message "Cmos Checksum Error" or similar You must go into the bios Setup and set at least the date and time to current settings to get rid of that error while booting the computer..
When the bios Setup settings have been set to defaults, if you have more than one physical hard drive installed, if two drives both have at least one Windows installation on them, the default settings may be booting from the Windows installation on the wrong physical hard drive.
The fact that you're seeing a multiboot screen where you can choose one of two Windows installations - a screen you haven't seen for years - one of which works fine but did not have malwarebytes and AVG and Kaspersky installed in it, leads me to conclude that you have at least two hard drives and the bios is booting from the Windows installation on the wrong physical drive by default, and that you have three Windows installations on the computer - two on one physical hard drive, one on another physical hard drive which is the Windows installation you were using previously recently.
To fix that situation, AFTER you have replaced the Cmos battery and have set the current date and time in the bios..
In the bios Setup, there is either
- a list of hard drives - they're usually listed by their model number - the model of the hard drive you want the computer to load Windows from must be listed first in the list, Save bios settings
- or - there is more than one hard drive listed in the Boot Order or similar list - they're usually listed generically - the model of the hard drive you want the computer to load Windows from must be listed first in the list, Save bios settings
Whatever the other drive(s) listed are, the one at the top of the list by default is obviously not the right one. If you have only two physical hard drives, the choice is obvious.
"malewarebytes and AVG and Kaspersky"
AVG and Kaspersky anti-malware software each have at least one resident module - a part of it that is running all the time in the background all the time in Windows looking for suspicious activity.
You should NOT install more than one anti-malware program in Windows that has a resident module, because the resident modules are likely to CLASH with each other and cause you problem, unless you DISABLE the resident module(s) of all such programs except one.
The free version of Malwarebytes has a resident module but it causes no problems; the Trial and Paid versions DO have a resident module that can cause problems if it clashes with the resident module of another anti-malware program.
"Anti-malware" programs also applies to anti-spyware software, and third party software firewall software. .
