Some things to look at:
Running to hot, with fans increased in speed, your machine may be throttling the
CPU down to keep it from cooking. This will slow your machine to a crawl. Three
big things can cause this:
1) More processes going on as software is loaded and the load for the hardware is
to great. Higher the load on the processor, the more heat it produces. (see #3
below) Possible malware activity also.
2) Your machine's HDD is running in PIO mode and this can keep the HDD activity almost
constant thereby slowing your machine to a crawl which increases the load on the
CPU, causing more heat. ( go into the device manager and look at the IDE channels
to see if they are running PIO or DMA).
3) Your CPU heatsink is becoming clogged so that the CPU can't cool, thereby throttling
your CPU down. They generally reduce speed in 25% increments, slowing your machine
down.
You can use this utility to watch the speed of the CPU to see if it is throttling
down when the speed is slower:

It works on most systems I have used it on.
