If your monitor is black but everything is still spinning, first off if you have opened up your PC check for certain if everything is connected again properly (especially the 4 pin connector near the CPU) and also the cable to the monitor and the monitor's power cable of course.
First of all try to connect your monitor to another device and see if it works. If it does not then your monitor is broken. if it does, let's go to the next step.
If everything is connected properly inside the PC, the odds are very high that your CPU and/or motherboard are broken. If possible try replacing the CPU and motherboard with another one if you have one lying around. If you don't you can either buy a new CPU or motherboard or if you want to take the more simple way, which is actually more recommended, go to your local PC shop and have your PC fixed.
Do one think just plug out Monitor to CPU cable , just on monitor only if so can you able to see one small icon go top to bottom its like keyboard, if you can see that, you don't have any problem on your monitor.
step 1 - just remove ram slot and insert again try to ON your system now
step 2 - take your cpu and connect to other monitor and check where it getting on or not , if monitor get ON and work good mean you don't have problem with your CPU , problem was in monitor to cpu cable ,so change your monitor cable its just cost of 4 to 5 $.
step 3 - take your monitor connect to another CPU , check weather you getting same problem if it work good mean, your CPU motherboard have problem just call your hardware engr to solve it,
GOOD LUCK ! if your problem solved don't forget to rate
These general instructions are intended to supplement or simplify some of the information in your motherboard manual
Make sure to read the manual that came with the motherboard - instructions differ for each one.
Ground yourself with any professional grounding equipment you have. Otherwise, ground yourself by touching the computer power supply.
Place motherboard on its anti-static bag.
Configure motherboard: Set jumpers or DIP switches for CPU, voltage(s), and bus speed, if necessary. If your motherboard is configured by software, you will need to configure it after you complete the physical installation.
Position motherboard in case. Line up holes in board with holes in case.
Insert spacers, plastic stand-offs, washers and screws, as necessary. Tighten screws carefully, but securely.
Make sure motherboard is not touching metal anywhere.
Make sure slots and connectors fit into openings on back of case.
Connect motherboard to power supply.
Connect CPU fan, if you have one, to power supply.
Connect reset and power switches to power supply.
Connect LED indicators to power supply.
Connect case speaker to motherboard.
Check all connections.
Test motherboard (and configure in CMOS if necessary) before installing other components of computer system.
TIPS AND WARNINGS
If possible, do installation in an uncarpeted area.
Be careful not to touch any chips. Handle board by its edges. Static damage (and even oil damage) may cause a failure months after the incident.
If you do not understand these instructions or you lack good manual dexterity, have a qualified technician install the motherboard for you
hmm sounds like a faulty motherboard first if you know anything about the insides of a computer try unplugging the HDD the ram and the disk drives and if you have a floppy disc drive unplug that as well. basiclyunplug everything exept screen power supply keyboard and CPU if the problem carrys on it looks like youll need a new motherboard
Power supply, that can be the cause.
Did you try disconnecting few devices to check if the CPU fan has enough power to turn itself on. Usually motherboard will have two connectors for the CPU fan, you may try connecting it directly to the power supply.
Also Check through the BIOS and see if there is a setting to disable the CPU Fan monitor (Hardware Monitor??) It should be where the temps and voltages are.
The BIOS in most computers has an option to monitor a CPU fan. If none exists, then the option needs to be disabled. I am assuming the error is occuring during the BIOS stage of bootup.
If the error occurs in Windows, it may be that some software has been installed to monitor a fan that doesn't exist. Sometimes monitoring software comes on the motherboard CD and someone may install it, thinking it is a driver. It is not necessary.
