The System don’t start at all :


These types of problems are easy to spot if you push the power button and nothing happens. The solution to these kinds of is usually quite straightforward, but the following symptoms will show you some of the wrinkles that may occur. Start with the following checklist, then see if you can match a specific symptom:

1. Check for AC from your wall outlet.

2. Reattach or replace the AC line cord.

3. Reattach the power cables between the supply and motherboard.

4. Check for improperly installed devices like expansion card, graphics card or dvd player also.

5. Replace the power suply.

6. Replace the motherboard.

7. Replace the CPU

The system starts but dont initialize :

Things getting only complicated as now we see power reaching the system and POST process is also starting, but a problem in the system is preventing the start up process. This can be motherboard problem, assembly problem like any component that is fitted on motherboard not working. Here we can start with the following check list  :


1. Reattach the power cables between the power supply and motherboard.

2. Reattach the power cables to all drives.

3. Reinstall all expansion cards.

4. Check & reinstall all signal like ribbon and cabling

5. Check for POST errors using a POST reader card.

     How you use POST READER CARD : Flip-POST is the Universal POST testing card

     designed to quickly and easily troubleshoot a dead PC in a matter of minutes in 3 easy steps:

a. Insert the Flip-POST card into a PCI or ISA slot
b. Power on the system. Flip-POST will display one (or more) error

codes (note: the first code is a card self test, see manual for details)
c. Look the code in the Flip-POST manual under the correct BIOS and you’ll know

exactly why the pc hardware isn’t booting.

6. Check the CMOS setup.

7. Replace the motherboard.


The System starts but crashes or reboots intermittently

Now many possible causes of crashes can be there. We need to first decide whether it is caused due to hardware or software fault. Trial error would lead us no where. The following steps are found to be useful, you too can try them:

1. Viruses can impair stability, so start the diagnosis with a virus checker.

2. Check device related problems and system errors in device manager.

Go to start -> My Computer / Computer -> Right Click on Computer -> Manage

Device manager gives you info on non functional hardware components, OS error,

application errors. This will give you an idea of what sort of problem has occured.

3. Buggy/Damaged Application  is a threat to OS stability. Stopping a software, Upgrading a

software and at last Uninstalling a software will solve the problem if it is caused by any


4. Start windows in SAFE MODE for few time and check whether this stabilizes the OS or not, if

it does then problem is caused due to some software error. If this also don’t solve the problem

then move to next step.

5. Driver updates can also solve your problem so think of it after coming to this step.

6. Still not solved now the time has come for checking hardware part. Change the AC outlet.

Change it from a high load point to low load point. Install a new surge/spike suppressor (or a

UPS). If it stabilizes the system its good or move to the next step.

7. Device installation problem could be a reason for this problem, so make sure expansion

boards and signal cables are seated properly. If boards are not fixed properly they can short

bus signals and cause spurious reboots. Check if any extra body is visible. Free the

motherboard and check. Check all the screws. Clean the entire system properly. Not solved?

move on.

8. Double check the power supply problems. Use a dc voltmeter to verify that each output from

the power supply is correct. Change the power supply. Not solved? move to the last step

according to us.

9. CPU overheating can impair stability, so turn off the PC wait for 15 minutes and check the

CPU heat-sink/fan assembly is fitted on correctly.  Check CPU fitting. System is still not



Last Hack and Slash Troubleshooting :

1. We tried all the available options to solve our PC problem but it dont just seem to solve, so

now start the Hack and Slash Troubleshooting. Remove one device at a time from the

system and check the system stability.

2. Restart the system after removing each hardware and check.

3. You can also change DVD-ROM drive as a slave on a secondary controller to the master

device instead and rest the current master device as a slave.



Sometime resetting system to the previous driver stage can solve the problem as some driver updates cause the problem. That’s all for now keep checking with us for more interesting topics on Pc Troubleshooting and Keep checking the other topics.
