I've done what you said, didn't bother with doing anything else shown on the thread since you just said to download FRST.
Just to recap exactly what i did,
I went to the thread, downloaded FRST, didn't do anything except press Scan, and saved the two files.
Also, bear in mind that i recently got my PC fixed, had to replace the hardrive. I may have to get it fixed again as the new hardrive has been making noises, and the other day i saw a blue screen (with writing). I'm planning on buying a new PC in the near future as this one is very old (2011 i believe, Dell Inspiron 1545).
