I have an emachine T5230. It will power up but after only a few minutes it shuts down. I thought the power supply was going bad so i have replaced that but it still shuts down. The heat sink on the cpu has a fan that only runs right at start up. Could this be the problem?
Any suggestions or is this something I need to take to the pros?

Re: emachine heating issues
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.

The first thing to check is to see if you have a dust problem! A lot of times the problem is that the processor heat sink is full of dirt. Take the fan off of it and do a good cleaning. Check to see if the air intakes are fouled. Intel processors have a safety feature that shuts down when the heat is too high. This is why it starts at first then shuts down. The heat is still an issue so the processor won't try and start again until the temps come down.
This sounds like either a power supply issue or a CPU fan issue to me. You say you hear a fan spinning loudly. Try and determine which fan it is. Take the left side panel off your case and start your game. When the fan gets loud identify which one it is. It's possible that the heatsink on your CPU is clogged up (pet dander, dust, smoke, etc.) and needs to be blown out. Get a can of compressed air and try blowing out the inside of your PC. It's possible your CPU/video card/power supply is just getting too hot.
Your eMachines features the cheapest power supply in the industry. I have personally replaced 6 of these. You can replace it with a factory unit for $20 or go to your local compter shop, and get a $40 unit that will last until you need a new computer.
Sounds like it is a problem with the m9700 overheating.
I have just repaired an m9700 with this exact issue and it was resolved by taking the CPU heatblock off, removing the dried/caked-on heat compound, and replacing it with my own (Arctic Silver 5).
Was 91c before, now down to 74c max on load (Measured with coretemp). Random crashing has stopped.
Hi there. When you turn on your system, enter the BIOS setup screen. Depending on your BIOS, you may have a section that tells you the PC Health Status. If you do, you can check what temp your processor is, and it may even let you adjust the warning temp, (it may be set too low). Some BIOS's will shut down a machine automatically if this temp is reached, to save the integrity of the system.
Yes, you may have a faulty power supply. Try testing it with another and see if the same thing happens. Also, make sure that your power supply is connected to your motherboard properly. Easiest way is to just disconnect it from the motherboard, check for any bent/broken pins, then just click it firmly back into place.
If you need me to clarify anything, just post a comment.
This may seem like to simple, but try checking to see if the technician plugged the fan power supply into the correct pin for it. It sounds like the fan is plugged into a external plug directly from the power supply and not into the board, which would control the fan speed for you. Give a look, and maybe it's just that simple.
I have the same T3256 emachine. It starts up then quickly shuts down. Sometimes it'll run for a few minutes and then shut down. I too replaced the power supply for 80 bucks with the same result. Then I thought, the switch is not a toggle on/off switch, its a push in, spring loaded type. I opened the front of the machine, removed the switch from the snal clips, open the switch (boy its small) vacuumed all the dust out when i replaced the power supply, and simply claned the internals of he switch. bw careful, there's a small spring that is easy to lose! I just did the cleanup thing again today. the firs cleaning lasted 6 months and it didnt start for nearly 4 years. So dont give up!! All I did was just scrape the contact wih a pointed knife until it was shiny again. Be sure to clean both sides.
1. Heat. Make sure the air vents on the tower are free from dirt and debris. Open the side up and, using a can of air found in most electronic departments at stores, blow off the dust on the fan and heatsink which resides on top of the CPU. Also blow out as much dust as you can. If your computer is fairly dusty then this should solve your problem, if not check out the other things.
2. Power supply. Sometimes when a power supply begins to fail, it doesn't put out enough voltage to the various devices inside your PC when under load. Swap out the power supply with one from a know working system to verify.
3. Memory. Remove and reseat the memory chips inside the computer. Download a program like memtest to run checks on your memory.
4. Hard Drive. Sometimes when a hard drive begins to fail, it loses valuable windows files. The computer chugs along up until a point it looks for a file then it kills the system.
Based on the issue you described, I believe it to be a heat issue as the computer is designed to automatically shut down if the CPU reaches a critical temperature to protect the internal components.
