Inexperienced And Need Help Lol

I am using an HP Pavilion g4-2149se notebook. Don't really know anything super specific, but it runs really hot and has even frozen up to the point task manager will not even open. I've got an older fan that hooks into the USB on it, and don't even think that it is helping at all. Anyways, I've been trying to find some sort of software that can help either control the fans or help keep it cool so that it will not die before I am able to upgrade. Any sort of information or advice is very much appreciated. Thanks in advance.

I'm posting in software because I really need to avoid having to purchase something at all costs. Just curious if possible to use software for temporary fix... Also, I can provide Speccy report.

 

That's what I was afraid of. Thank you my good sir.

 

Making sure the inlet vents are being blocked by anything try pointing the vac at the outlet vents while the comp is running. This may help a little but the job needs doing properly as has been suggested. You could also get a can of compressed air and blast the inlet vents first.
