Re: emachines T2958 overheating and shutting down
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)

I can't see your car but doubt the battery is the culprit and only slightly suspect the alternator.
If it were my car I would plug in one of those cigarette lighter voltage monitors and watch it closely. It will tell you more than any mechanic can by examining the car while you are not having the problem.
Your car's voltage should never go below 13 volts while the car is running, and as high as 14.8 volts shortly after you start it. It should also not be below 12 volts before you start the car and after you shut the engine off.
If you notice the voltage is lower than 12 volts before you crank the starter, the battery is drained too much, and that could be because something is draining it. Suspects could be anything from an alarm circuit to the radio.
However if when you start the car the voltage doesn't go up to somewhere around 14 volts, it may not be charging properly, and it sometimes when it's running it's voltage drops below 13 volts, then you know the charging circuit isn't working.
If it sometimes goes over 15 volts while it's running, there may be a bad connection to the battery.
I always remove and reconnect the battery connections whenever I suspect I have a battery problem, it's just so easy to do and often the problem.
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.
The PSU voltages can be checked with a digital multimeter at the ATX connector, 3.3v (orange), 5.0v (red) & 12v (yellow) if the DMM is indicating values of MORE than 5% variation your PSU is the likely villain (best to rule it out first).
Are you getting a BSOD (Blue Screen Of Death) or error messages when you PC randomly shuts down?
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.
your files might have been corrupted i know the end close screen file sometimes and will get corrupted quicker than startup screen
now the question is was this the floor model or a straight out of the box unopened comp cause floor models always needs to be reformated those are the show comps. people play with those all day once you reform. comp. and put in new O.s. system everything should come back to working perfectly and dont forget spyware checkers and virus blockers name branded backed up these will help protect your comp
simple other solution might be you just need to upgrade your system files threw windows update
Hi James, replace the fan or If it's still under warranty have it serviced. Suggest you stop turning it on until the fan is replaced. It could be the fan cooling the CPU. You don't want it to fry.
The shut down process is normal when over heating is detected by the system.
