If there is a excessive heatup or a short circuit in cpu or if there is a surge in power, The systems protection mechanism kicks in and stops all the processing. The reasons might have fried up some cpu components which is why its not restarting. Try some more restarts and If the cpu is not working at all, then there must be a problem with the power supply

My system suddenly hang when we restart it, monitor does not get any signal. After when we get rid hard drive motherboard was working. on other system my HDD is working fine.


This is usually dust clogging up the CPU cooler.
When the owner of the PC forgets to clean the fins and the fan of the CPU cooler it plugs up with dust and dirt and looks like the inside of a vacuum cleaner.
There is not enough airflow and thus not enough cooling, so the CPU overheats and the safety circuit shuts the CPU off until it cools down, and the CPU will not reboot the PC until it is cool enough that the safety circuit can reset.

First step remove the CPU fan and check the fins of the CPU cooler. If they are clean, the problem is usually somewhere else.

Suddenly stopped working ,won't restart my PC?


First of all disconnect all peropheral connected to your motherboard. Take out Your RAM and clean it with soft clothe. Reinsert ram and restart your PC. If you can get display at this point then shut down your PC connect all peripheral back and restart your PC.

If not you will need to replace your ram.

My cpu is on just i power off the monitor.,series is samsung SyncMasterB1930 is the model., now when i am trying to on the monitor the monitor is not responding it is still power off mode.


First check if the monitor is functional by removing the monitor cable connected to the CPU, once disconnected you should see a onscreen display on the monitor (Keep the power cable intact).

Second check if the CPU is working (not stuck / hung) if you hear the windows logging on sound, then your CPU is fine. If you do not have sound enabled during startup or no speakers then once the system is on give it some time to load windows and then keep tapping the Caps lock or the num lock key, if the lights respond / glow on and off when you press the keys then the CPU is working.

Third check if the CPU has two display ports (in case if you have a onboard VGA and a seperate video card) disconnect it from one port and insert it in another port and restart the computer and see it it works. If you do not have two video ports then skip this step.

Fourth - Restart the computer and keep tapping F8 Key while restarting, in the windows advanced menu choose enable VGA mode or Low resolution video mode (based on XP or Vista/Win 7 the menu changes), if you can see that menu then the issue is with the display settings only. Once in VGA mode or low resolution mode reduce the video resolution settings and restart the computer.

Please revert if you need further assistance, or clarification.

No any display in the monitor, no beep of the RAM while CPU fan is running


Check your power supply. It sounds like you have a bad power supply. Even though the computer powers up, it does not mean that it's good. I have had this problem before, and almost 9 out of 10 times the power supply had gone bad. Just try a different one and see. hope this helps you.

How to repair my system


Hi, the first thing to try is to make sure your craphics card has not worked loose. If this is still firmly in place then try a replacement card. When your system boots and hangs up it is usualy either RAM chips loose or failed and as you say the system boots ok then it will almost certainly be the craphics card at fault. Regards mistyman

Pc is not working


as computer starts hold down F8 and youll see a safe mode. use the safe mode and it might just come back, restart it....sometimes strange viruses does this but i dought in your case.it should come up in safe mode allowing you to save your files ...folders to cd record disks...then you can format and reinstall all programs.

I have intel gvsr motherboard hangs every 3 to 4 hrs


Dont overclock the CPU, and underclock the GPU and see what happens... This should solve it, along with adding a fan or two with a thermostat!
