A few weeks ago, I put my computer in sleep mode. I left it there for like half a day. WHen I clicked the mouse button to take it out of sleep, inside the computer started to make a loud rattling, buzzing, vibrating sound as the fan spun. So basically it started after it was sleeping and waking up to get the fan going. This has never happened before. I shutdown the computer and started normally and after that the computer sounded normal.
Now, sometimes when I start the computer even starting normally inside the computer makes similar sounds. Anyone know what is going on? Is this possibly a fan that has gone bad or something? Could this be the fan on my video card going bad? I did a web search and read where someone had something similar and thought it was their motherboard. I'm not good with computers so have no idea and am a little overwhelmed because I try to take care of my computer and hope its not something major. Thanks for any help.
