just now i noticed that my pc memory was back to 256 and its 512. There are 2 256 on the board and even a drive thats no longer there comes up as primary slave at boot. i went into cmos to change this but the disk wasn't there either. i tried removing the memories but still the same 256. help wud be appreciated

Try getting rid of any new thing you installed.
Or reset by back dating the pc.
And try getting rid of any thing you do not need.

i just reinstalled windows so its not as if theres anything on it thanks

thank God i just repaired it all i had to do was switch the positions of the memories
