Hello

I copied a file which was only 3mb & it took like 5 minutes. Since I have an Intel core 2 Duo 2.66mhz processor, it doesn't seem normal. I recently installed CPU killer, which I used to slow down the processor for a game - but I unistalled it as it made no difference & was wondering if that might have DONE something? In PC Wizard 2008, it's showing my processor running at 1600 mhz instead of 2666 (this was also the speed while I was copying the file).

Concidentally, I've just started getting a warning from my Intel desktop utilities:



Here's PC Wizard showing my processor running at 1600mhz:



What's this all about guys?That's known as throttling, your CPU will slow down and reduce the voltage to decrease heat output and power consumption.
It shouldn't affect your overall speed, as this only happens when it's idle.
Is the computer overall running slower?
Keep checking, measure the speed after doing something demanding and see if it's different.
Also try copying the file again, is it faster or the same?HI, I restarted & tried it again & it's still the the same - slow copying, and now applications are not responding.

The temperature of CPU is 53c - is that normal?

While it was copying, down the bottom the processor activity was showing no more than 10% (if that's helpful?)

I just got a pop up from intel utilities saying 3.3v out of range - *CENSORED* is going on?53C for that CPU is not normal, no.
Follow the instructions here to clean your PC, this will determine whether or not it is a heat problem.The PC isn't dirty, I recently installed a video card & it's squeeky clean inside.

It seems to have somehow returned to normal, I copied the same file & it was instant... weird...

Anyway, thanks for your HELP Calum.Try DosBox for those games...
