Back with more questions
..with more questions of course..1) Will it be detrimental to my monitor if I constantly switch it on and off? The duration can be as short as a few minutes to as long as an entire day.
2) Using SiSoft Sandra, these are what my temperature sensors indicate:
Board temperature: 64.5C / 148.1F
CPU temperature: 44.5C / 112.1F
Power/Aux temperature: 42.0C / 107.6F
It is clear that my motherboard temperature is too high (there's an exclamation mark next to it) so what can I do about it? I don't know how to install a fan ON a motherboard, just those that blow out behind the CPU.
3) Is it OK to just open the side cover of my CPU and have a fan directly blow it? Will it be detrimental to the CPU health as well (dust particles and stuff)?
Thanks again.

Oh yeah... on a side note, my motherboard is a MSI 82865G/PE/P, 82848P DRAM Controller board. I've been trying to find an update driver on the net, but no luck even on the official site. It's not been updated since it was installed nearly 2 years ago. If you happen to know of a site which contains the driver update, please let me know

I think I see the problem now.
When I built my last PC, I bought filters for my fans that have kept it largely dust free. Definitely worth the few cents it cost.
