Desktop running on speed!

Don't know if this is the right place to post this, but please direct me to the right place if not.

My desktop appears to be runing on speed!

I switched it on, and that startup screen with the four coloured windows logo, is flashing like mad. The next screen I get is the password screen. On here, the cursor is spinning like mad. When I try to enter the password, pressing the first letter fills the input box with characters. I don't know whether this is the character I have just entered, although I guess it is. If I try to delete the characters, pressing backspace deletes all characters in the input box. Pressing the first character goes through it all agaiin.

I now have a desktop that I can't get into because of this. Nothing new has been added...software or hardware. Everything has functioned as normal prior to this.

Anyone help?

Try rebooting in safe mode (F8) with networking.. If you can I would check for malware by downloading Malwarebytes and running it.

Tried that., and no Malware / Viruses were found.

So booting into Safe Mode does not have this speed issue?

If not then at least you can narrow away the possibility of it being an issue with anything related to his mouse or keyboard. Although a spinning mouse cursor? I've not seen that before. Hmm

When you say the cursor is spinning like crazy, do you mean something like this one?


If so it means stuff is running in the background.
