Quick question if anyone can help out. Yesterday I painted my room so I had to take out my computer and later when i plugged it back in my computer made a beep sound (1) and it showed up with a screen showing how fast my cpu is and how much memory i have etc. It showed i had 512 mb or ram when i have a 1x1 gb stick installed then it said to press f4 to resume so my OS can startup but then i restarted it and i went into my bios and it said i had 1gb of ram so i exited out and saved all changes and everything worked fine and then i went into my system info to double check and it said 1gb so everything was correct now. Do u guys have any idea why it does that? its the second time that this has happened.
