OK my computer is constantly freezing, I've come to the conclusion that it is over heating (I've pointed a household fan towards the open case and it works fine, never freezing up)

Things I checked-

-The Graphics card, was an nvidia 7800gt, i took it out and used on-board....still overheats.

-The Power supply, I recently completely replaced it, with a new PSU that has two fans...still overheats.

-I took off the heat-sink and applied thermal compound.....still overheats!

Now I'm not even over-clocking, I have 3 standard case fans, and the new PSU has 2 fans. I should not be having an overheating problem, but for some reason It freezes up when I do simple task like browsing the internet or listening to music (not just when I play games)

I have a
AMD 3800 X2 processor
4 gigs of ram
Gigabyte GA-M51GM-S2G Mobo
Power Star 600 W watt Dual Fan ATX PSU
Windows XP MCE (use to have XP pro, same problem)

I'm not sure if it's a memory problem or not...because 4 gigs is more than usual. But it doesn't seem like that that should be a problem since it is supported by the mobo.

Appreciate any help.

My first sense is that it is not a heating issue. So, how do you know it is overheating? Do you have onboard utilities that tell you the actual temperature? My box has a video card fan, a cpu fan, two fans in the power supply, and one case fan, and I have no issues. Oh, I have three hard drives in near constant use, and I do extensive development on my system, meaning that I may have two or three virtual environments going, an IDE, a couple browser windows, several database applications, a web server, and two or three command windows. (I work the heck out of my system)

When you say freeze, do you mean "freezes so that I have to kill the power to restore it", or is it just stuttering for a few seconds. There is a big difference. I have had people tell me that their Scan Disk wasn't working because it kept freezing. When I asked how long, they would say "like 10 seconds or so". (Darn impatient kids anyway). At any rate, total freeze is one thing, stuttering is another, and application lock-up is something else. So when you say 'freeze', I'm thinking that you need to toggle the power to get going again.

When it freezes, shut it down, unplug it, open the case, hold onto the metal of the chassis with one hand - and with the other hand gently feel each component (careful - it may be very hot!). Be sure to check the CPU, the vid card, the memory, the hard drive, and the north and south bridge chips.

The hottest one is likely to be your problem.

Yea I figured out it was the north bridge chipset, the only component I didn't think to check until someone on another messageboard suggested it. I replaced the stock heatsink with a better one and it's seemed to work fine so far.

(And yes groovicus, it was freezing completely so i had to restart, and the reason i could tell it was overheating is because it worked fine with i had a big fan pointed it)
