Re: emachines T2958 overheating
Even though it is reporting thermal shut down, it may not be what the problem really is.
I've gone through this with Dell GX260's (same error, same function after. Or you can turn it on 7 or 8 times, and it might finally work).
Look inside the computer at the motherboard.
And look for the capacitors (they look like little cans standing on end, about 3/8" to 1/2" tall, about 1/4" in diameter).
If the tops are slightly dome shape, or they have a brown sticky substance around or on them, the motherboard is shot.

When the CPU in the computer or laptopoverheats then it will shut down (i.e. thermal overload) and won't boot upagain until it has cooled down. If this is the problem is not fixed then theCPU will eventually fail. A faulty fan causes this problem or the fan and heat sink assembly are cloggedwith dust. Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged withdust the remove the dust and make sure the vents are clear and dust free. Use acan of compressed air to do this.
Try blowing out any dust from around the fan with compressed air. If the fan is turning on and off a lot, this could be normal, depending on your processor, but if the system just shuts down fully and randomly, it would be a heat issue. The CPU is overheating and the failsafe mechanism is to instantly shut your computer down. The only way to avoid this is to raise the CPU shutdown temp in the BIOS settings, or if you can access the CPU, remove it and apply new, quality thermal grease. Also, ensure the fan is operating correctly during use and dont block any air intake or exhaust ports.
try applying new cooling pest between cpu heatsink and cpu. Heat from cpu surface should be quickly transferred to heat sink. Either coolent problem or heatsink doesnot properly fit on cpu. But be carefull, you need an 'EXPERT' to do this, or you end up damaging everything.
If the computer detects overheating or fan failure it will shut down automatically. If you replace the fan you should be fine. Remove your old fan and try to get one that connects the same way, some of them connect directly to the heat sink, others to the motherboard.
Your computer is automatically shutting down to prevent damage to the CPU because it is getting too hot. This can be caused due to a malfunction fan, heatsink, or dirt inside the CPU.
Remove the side cover of the CPU. Using a can of air (which can be purchased at most electronics departments), blow out any dust inside the case, paying specific attention to the fan and the heatsink mounting the CPU. Also blow out all vents and anywhere else you see dust. Do not shake the can of air and keep it as level as possible. If you do not have a can of air available, an air compressor will work. Alternatively, you may vacuum the dust up with the hose of a vacuum cleaner but do not use any attachment with brushes on it.
If the inside is relatively dust free, check to make sure all the fans are functioning properly. If the one on the CPU is not, then that fan will have to be replaced.
And one more thing, please give this solution a fixya rating. Thanks! :c)
Hi rebecca_fran, Well the system is shutting down for a reason but before you run off & buy a new CPU fan I want you to try something. Unplug the power cord from the PC. Open your case & ground your self by simply touching any bare metal. (The bottom of the case will do). Please remove the memory currently in your system. If you have never done this before please check within the manual for your eMachine. (There should be a section on how to install memory). You can also click on this uTube link, it’s a bit long but you can skip through the video. http://www.youtube.com/watch?v=SsXNT6fnHmM&feature=related If you have some canned air blow out the memory slots. (Do not place your fingers on the memory contacts at any time). Re-seat the memory, firmly but gently. Leave the case opened & plug in the power cord. Turn on the PC. See if the fan runs & the system doe’s not shut down. If it still does replace the CPU fan. Your PC uses an AMD Athlon 64 X2 4400+ / 2.3 GHz CPU. Here is a replacement AMD CPU fan & assembly. http://www.endpcnoise.com/cgi-bin/e/std/sku=dual_core_cpu_fan.html The CPU will come with thermal tap on its underside. (No need to buy thermal grease). (Make sure you remove the old thermal grease from the top of the CPU). Use a clean rag with a little alcohol on it. (Not dripping). Allow time for drying. Do not scratch the CPU surface.
