Once my computer boots fully and displays its temperature monitor, itвЂ™s at around 10C. The thermal shrinking seems to be causing the fan to grind against its housing. IвЂ™ve been having a similar issue, Judy, and the conclusion IвЂ™ve come to in my case about the noise is that my computer room is getting too cold at night and IвЂ™m starting my computer before the room warms up in the morning. ThatвЂ™s probably what you want to be looking at first. Like I said, the fact that youвЂ™re experiencing severe system slowness while this noise is happening really has me concerned about the hard drive. ItвЂ™s usually pretty clear вЂ“ itвЂ™ll probably be coming from one of the fans or from one of the drives. My approach would be to open the box and just listen carefully to from where the sound is coming. YouвЂ™ll first back up, then replace the drive, and restore all of your data to it from that backup. ThatвЂ™s why I started by saying back up, now, while itвЂ™s still working.Д«acking up really is the first step of what turns out to be the only real solution. That typically means that when that thing becomes completely loose, itвЂ™s going to go flying around in there and cause all sorts of destruction within the drive itself.ДЄnd that kind of destruction is typically irrecoverable. That grinding noise is something loose inside the hard drive, where there simply shouldnвЂ™t be anything loose. Internal destruction is usually whatвЂ™s next. ItвЂ™s a precursor to something much, much worse. Sometimes, when a hard drive is failing or about to fail, it can make those kinds of grinding noises. If your machine is working and youвЂ™re not already backed up, stop reading right now and back up that machine.В Your data may be at a serious risk of complete, irrecoverable loss. The other option that concerns me is the hard drive. I heard it and I fixed it simply by moving the cable out of the way. I rerouted the cable to make room for the hard drive and as a result, the cable ended up sitting in front of the fan. The most recent was when I installed a hard drive. ItвЂ™s fairly easy to fix if you open up the computer and look for things that are bumping into the blades. If there is something partially obstructing the fan, the blades could be hitting it and that could easily sound like a grinding noise. They do this at start up to make sure that the fans work and to dislodge any dust or dirt that may have accumulated that a low speed wouldnвЂ™t just blow out of the way.

One is something that you should deal with, but itвЂ™s nothing to really panic over. Go to Product Repair.There are two possibilities that come to mind.
