I would look at cooling the Motherboard and the 2nd drive, the CPU and AUX are not unusual

I would also look at hardware issues, so try tuneup trial

http://www.tune-up.com

Run disc clean up then registry clean up then click optimize to run reg defrag, which takes a while then needs a reboot. After the reboot, click optimize then system optimize then optimize the computer and then the internet configurations, each need a reboot.

With these out of the way, the software side should be clear, leaving hardware, possibly the drivers for the video adapter

sometime the psu can cause a heat up problem too. Was it only replacing fan that cause this problem or did you replace anything else? Also make sure your case has clearance and make sure that you are not activily overclocking. Yeah and clean up your registry via, msconfig so not as much stuff loads on startup and download the 15 day trial of diskkeeper and defrag if you can with nothing else running. Why did you replace that fan with a worse one if i might ask? lol

Yeah, if the back of the case feels hot then that would indicate it could be the PSU instead thats overheating. The cpu temps are not really high enough to cause the shutdown problem, unless the temperature rises much above the figure given by everest.

What make of PSU do you have & what power output rating is it?

It could also be your video card thats getting too hot, but if the case feels warmer near the top, then more likely its the psu.

Which fan did you replace?

well....i think i found the problem....apparently my motherboard fan (the one on the rear end of the machine) has stopped rotating. this is where the heat is coming from also, so that makes sense. im almost 99% sure that this is the problem. so would i have to replace that fan? and if so...how much would something like that cost and where is a good place to buy one? thanks again for all your help

You can check the wiring, if it is in place, remove the fan, take it to a shop and ask them to test it, if it does not work, get a new one. Ask them if you can get an uprated fan.

Where to buy depends on your location but the cost will not be prohibitive

Keiths right, the fan shouldn't be expensive but I'm not sure whether you mean the fan that is fixed to the case & connected to the motherboard or a fan that actually sits on the motherboard (eg chipset fan) or do you mean the cpu fan?

Worth checking with the manufacturer of the power supply or a PC shop

If you want some excitement and are are knowledgeable in Electronics, you can
clean your PS Fan. If this baby gets gunked up with lots of dust and crud, it
will slow down and not move as much air out of your PS and eventually fail.

Thus causing the PS to overheat, and shutdown.

While your at it, you should make sure ALL your system fans are clean. Again
crud on the fan kills the performance of the fan, not able to slice through the
air as good.

If your case supports to back fans and a front fan... populate it with the fans.
