How can I fix my power supply?
I have a Emachine, which I think the power supply is not doing its job. I have money, so I'm wondering if anyone knows anything about them to repair? It is a Bestec ATX-250-12E
Hello: You state that you do not believe that the source Emachine Power is doing its work WHY? What are the characteristics you find that lead to this conclusion? In any case – Opening the Computer Case and clean the fans, the heastinks, and all the dust that accumulates may be all you need to do. As heasinks, in particular, are covered dust, food and the CPU overheats, it can can cause severe stress on otherwise "working" parties. DO – to disassemble the power supply and the explosion in the air after using a screwdriver or pencil to block the fan blades spin. Use a damp cloth to clean screwdriver areas that the air is not clean. Just unplug the power cord before cleaning. Again, usually there are 4 screws holding the heatsink fan of CPU, which has been eliminated, and make sure the heat sink fins are clean. I repair power supplies, but "repair" WHAT? You is very vague. IFit isn't broke, can not be fixed. If your computer is working, what makes you think that the power supply is not "doing their job." If the power supply was not working, the team would be totally dead … The Bestec 250 normally maintain a platform of the machine is very good – I've seen PACKED solid food sources with dust, and played with the power supply and motherboard. If you have added all sorts of things in the eMachine without upgrading the power supply to height, Then you would have problems .. You do not state what he did, or what is the problem. CLEAN everything on your computer can make a difference alone. "Repair" a power source means that something is broken, and does not express what is broken. Post back a note explaining the problem and people can help. Did you know or anything you add devices to your machine? Is the machine dead? Have you looked at the heat sinks on the CPU and power supply and full of dust? Carefully taking the machine apart and cleaning is trivial, but if solid bags, will run the machine as efficeintly again. You also could have problems with Windows software XXX (not specify) slow to a crawl with dozens of programs running at boot (bad) and large folders time was filled with hundreds of megabytes of trash, and spyware and adware and other pests from slowing you down – in which case it is necessary to make a full FDISK, FORMAT, reloading windows, and install Spybot, adaware, firewall and antivirus, and start again. Please send a note to describe the current state of his team, and what is wrong. I would "fix" the power supply at the bottom of a long list of things to do first. Once SEVERELY damaged a power source, probably not worth the effort to fix it – I just overheating of the power supply of the machine I'm writing this in, and just put in all capacitors back into the power supply and motherboard in the 3.3 and 5 volt rails. I was lucky that I caught the problem before it destroyed both the energy supply and the motherboard. The heat sinks were covered with dust, the CPU cooler was connected, and this helped to overuse the computer when heated. Only the cleaning only does this unit work better than it has in a long time – I had no idea it was as bad as it was, and the dust heastsinks was not visible until I started the separation equipment. The power supplies that will upgrade capacitors, coils transformers update, add missing components, update the resistors used to burn Votage, add fans, alter the "silence" implementation circuits for fans to run on premium of 12 volts, and modify other characteristics. If the driver has been integrated chip, or high power rectifiers are cracked so I just used the parties for energy. My standard solution to a small power supply is to add one or two people – old AT power supplies are free, and with the 12 volts out in the first or AT ATX, go to a repeater shelf of 12 volts (a car, a coffee machine, microwave, etc.) can run any number of Power supplies with 110 other entries. The results of the power sources added that the route of hard disks, CD's, fans, etc., while the original use just for the motherboard. You must be energy power sources added "Good News to the 5V, but this is the only modification really needed. I also cut all the tracks are not used at all power sources to keep things clean. I hope this helps please post an update – I'll check again Robin
