You found 3 fans. Why not order new ones and replace them all? These are only good for a few years and any Pentium 4 is well past the time that we expect these to last.
I got a message yesterday when I started up my computer that said:
Fan Speed Too Low.
I was then prompted to press F1 to fix it or ESC to exit and continue with my normal start up. I pressed ESC because I didn't know what to do.
The computer I own is a Sony Vaio VG3-RB30 desktop. Windows XP operating system. Intel Pentium (R) 4 CPU 3.00 GHz. 504 MB Ram. Service Pack 3. With 128 GB free space.
It has been making some really weird noises the past couple of days. Kind of like a mini weed-whacker.
What do I do to fix this? I opened up the tower and cleaned out as much dust as I could. There are 3 fans in there. 2 with easy access, 1 that's more difficult to get to. After the cleanup the noises were still there. But not as bad.
Also, on a side note, Firefox takes forever to load on my computer. Any suggestions to get it to load quicker?
Thanks a lot for your potential responses.
