The "fan twitch" you're seeing is a nearly certain proof there is a short circuit somewhere. It could be the PSU, it could the the motherboard, or anything directly connected to either or both of them.
You need to reduce your machine to PSU + motherboard (out of the case/on the table) + CPU (with heatsink of course) + one stick of RAM + video card (if there is no integrated graphics). Reset CMOS, re-seat your CPU, cleaning the old and applying a new coat of thermal paste as needed, re-seat RAM and a video card if needed, then try turning the machine on. You can use a screwdriver head to short the power-on pins on the front panel pinout of the motherboard, if it doesn't have a dedicated power-on button on it.
If it still just twitches the CPU heatsink fan, remove graphics card (if you used one), connect a speaker to the front panel pinout (if the board doesn't have an integrated speaker/buzzer on it) and listen for an error code. If you didn't need a video card (have onboard/integrated), then remove the RAM stick and listen for an error code, if the machine even starts.
Reducing this to PSU + motherboard + CPU problem, means you should try a different PSU. If the machine still doesn't spin the fan, your motherboard is shorted somewhere, probably the VRM.
Thank You For Using Flixya and expected to see again
This seems like a power management problem on the motherboard.
Disconnect the power cable. Remove the small silver CMOS battery for 2 minutes to clear the BIOS Memory. Reinstall the battery and reconnect the power.
Look carefully at the power lines coming from the Power Supply Unit (PSU) and make sure that no one power channel is powering an unequal load of devices. Try and divide the load as evenly as possible amonst the power lines.
If none of this solves the problem, then consider upgrading the fitted 300W PSU to one with a higher Wattage, as 300W is on the low side for current standards. 450W-500W is more typical nowadays. The higher the Wattage you can afford (up to a 650W maximum for this particular specification of PC) the better
A higher wattage PSU will work well within its capacity and therefore under less strain than the current one. The symptoms you describe could be signs of the current PSU straining at the limits of its performance range to power all the devices inside as well as maintaining the computer's heavy workload of interaction with all the devices connected to it.
The only thing i can suggest is remove one of your RAM sticks and see if the machine will boot. I had this problem with mine and it turned out that one of my RAM slots was faulty and would not boot if both RAM slots had RAM in them.
Choose within this options with regards to your monitor:
1. You could replace your monitor with a new one.
2. Or you could send someone or send it to a technician to repair your monitor.
Boot Up Problem:
1. Try checking the Power Supply Unit (PSU) if it give out 12Voltz. If not you could replace it with new PSU.
2. Check the motherboard if there are some blown out Capacitors. If there is, send it to a technician to replace it. If none, replace your Processor. That is the defective. That causes the boot up problem.
On boot up screen. Of course it will not show a boot up screen because there is a problem on your monitor. And so, there is also a problem on your motherboard (Processor or Capacitor).
Hope this might help. Thanks.
From what you are descrbing it sounds like a PSU issue
Please try the following
1) Remove all the wires from the PC
2) Press and hold the power button in for about 10 seconds (yes i know there is no power :) )
3) Plug everything back in and retry, if it still fails the Power supply will need to be changed
The Power supply can be swapped out at any decent PC repair shop and is quite cheap to do
Try reseating the RAM memory modules, see if any change.
If no change, remove, battery, Drives, Wireless card and RAM, see if the system will run longer or give an error code. If something changes, add 1 RAM module and try again. If the system runs, then add items back one at a time until you determine the faulty item.
If the system issue doesn't change, odds are a motherboard problem. Motherboard are about $100 on Ebay
measuring 12v at the psu is not enough.
the psu have several voltage outputs ranging from 12volts to 3.3 volts and maybe even 2.2 volts..
firstly, check all onboard USB ports, a bent or shorted pin in a USB port will prevent the psu from operating.
next, the psu has a safety connection to the mainboard, this is called the power good signal ( pwrgd) and it is a signal from the psu to the mainboard and tells the mainboard that everything in the psu is functioning correctly. If the powergood signal is lost ( drops from 5volts to zero volts) the mainboard will issue an interuppt to the cpu and the cpu will shut down, this will also shut the board down to prevent damage and data loss. mainboards all use pretty much the same connectors so your board will have either a 20 pin power connector or a 24 pin one. It may also have an additional 4 pin connector to power the cpu and northbridge functions.
use a known good psu and plug this into your board along with the 4 pin connector and attempt a switch on. If the system begins to boot, replace the psu. if not, try unplugging or removing everything connected to the board, pay special attention to expansion cards and usb ports.
remove the ram sticks and video cards if fitted, then attempt to boot again. if the system does not respond, replace the main board. if it now begins to boot, refit everything one item at a time and try starting the machine. turn off before refitting the next item and start the machine up again. when you get to the problem item, the machine will stop starting.
If all else fails, replace the mainboard or take the machine to a reputable repairer..
