Since around 1 month my pc is constantly overheating, my fan is turning in place and not completely, my hard drive is making a constant grinding noise and it is slower than before at start. Other than that, it is working perfecly. My pc is a Dell inspirion 5100. I wanted to know if anyone knew what type of problem it is, how to proceed and around how much it would cost. Thanks

If you are comfortable with doing so, opening it and checking the cooling system would be the first thing:

For your purposes, you can skip to this section:

In the past I've opened up laptops that had so much accumulated dust and crud blocking the intake of the heatsink that it looked like a piece of felt. This is far more likely to be the case if you have a pet (or multiple pets).

Most computer fans have permanent lubrication, but you could always try a drop of oil near the base of the spindle. If you have to, replacing the fan in an older laptop isn't that expensive. I usually purchased parts on ebay, although you do need to know enough to avoid used parts that have been "used up".


If your 5100 is still using the original hard drive, there is a very good chance it is dying, as it would be well past the failure date for most hard drives. That could be true even if it replaced. Normally I would recommend replacing it with a SSD, but the 5100 is so old it still used an IDE hard drive.

The good news is the hard drive on the 5100 is very easy to replace:

Unfortunately, since IDE hard drives are old tech, a lot of places overcharge for them, and buying a used drive is a bit of a gamble. Unfortunately, if money is tight (and I suspect it is since you are using a laptop that old), you may not have any choice.

That's a big difference between the two...lol ! I was going to recommend a bullet to the old Dell at fist . I have one of those sitting in my closet waiting for me to install a Linux distro on it . Now , since you have a newer one I would also recommend a new ssd drive . Also get an external portable ssd for storage . The fan is most likely clogged with lint or pet hair . If you have any questions you can pm me . I work on friends desktops & laptops all the time . I have a collection of old Dell laptops too .

For that one, here is the manual:
http://downloads.dell.com/manuals/all-products/esuprt_laptop/esuprt_inspiron_laptop/inspiron-15-5547-laptop_owner%27s%20manual_en-us.pdf

See page 17 for the hard drive, page 26 for the fan.

Since this one is new enough to use a SATA interface for the drive, seriously consider going with an SSD if your hard drive is failing. Whether that is a viable option depends on your budget and how much space you require. (I see this unit originally shipped with a 1TB drive).

If you don't need much space, I've purchased 120GB TLC units (Silicon Power brand) for around $30 each, although I would recommend going with Samsung if your budget can go higher. Those start at around $70 for a 250GB 750 EVO. You can get 1TB SSD's, but those get rather pricey (from about $200 to over $300).

That said, while it isn't impossible a hard drive of that age is failing (especially if the machine has been bounced around a lot), I wouldn't say it is likely.

Overheating is very likely caused by a clogged up air intake indeed. You should be able to unscrew the bottom part, and then take off the cover (don't be rough, might have plastic hinges). Once the cover is off, you should be able to remove the dust with the help of a q-tip and possibly a more pointy tool. Usually the dust accumulates inside the small fan, as well in the filter/heatsink that's probably installed in front of it.

I've just unscrewed the bottom and cleaned the fan and pretty much the whole thing, the hdd still has the same problem so I will need to buy myself a new one. Thanks everyone for your help. If I need help with my computer when i'm changing my hard drive I might pm some of you. Thanks again
