Hi enipuskas, welcome to 7F!
- When you say incorrectly you mean all those accents above/beside the letters. The fractions, % signs and ¬?
- Is this all incoming messages or just from certain senders?
- Has this just started?
- How long have you had your HP Pavilion dv6 Notebook PC?
- Is the dv6 fully updated?
I have to look back in my posts, but there was a similar problem, and it was narrowed down to incorrect encoding by the senders email system.
There could also be a conflict in language packs. Have you installed any?
For the time being you could try running:
SFC /SCANNOW Command - System File Checker, run it at least three times even if it reports all is okay.
EDIT:
