[ModeX]

every time I change the time it always resets, even when I change the bios time!

Can you help me?

Check you CMOS battery.

 

[ModeX]

do I reset cmos?

After what does it change ? After a restart ? Or just randomly ?
Usually, this is just a case of your CMOS battery being out of juice...
Weird though, as I'm sure that motherboard of yours is a new one...

gravity, that is what I thought - "new board"

ModeX, try another CMOS battery. Reset the CMOS and then try it.

you need a 3V CR032 cell to replace the one on your mobo.

Have you been playing around with the CMOS jumper ? If so, maybe you short circuited the CMOS circuit, and drain the battery rapidly...
But then again, same answer, replace the battery...
