Try clearing the memory, clear the CMOS on the board.Then start again, if still wont start, replace the RAM with new ones.

If there is noise "beep" then it has RAM issue/RAM port. If is not noising then it has motherboard issue. I guess you need to take it to the technician and ask him to fix or replace it.

I have HCL Ezeebee desktop computer when we boot the system monitor, keyboard, mouse blink for a while and monitor (HCL) show 'no signal' message, and keyboard num lock led not display mouse i


No signal at the monitor indicates (if you know the monitor is working ok) a failure of the graphics chip or graphics card, The lack of indicator light on the num lock LED and the lack of power to the mouse would indicate that there is a major issue with the motherboard.
you can try using another monitor to confirm the problem lies with the graphics, and in the case of the keyboard and mouse, swap them for a usb version, if they work, the Ps2 ports are probably damaged.
I'd be thinking of replacing the motherboard

On start up fan runs, no beeps, black screen, no response from keyboard & mouse. Unplugged everything for 30 minutes, then tried again, start up began then went to black screen, no keyboard, no m


in your case, there might be some problem with the main board.
usually no beeps will related to the processor error / mainboard error / ram error / PSU error

to check the processor : try to exchange the processor with the same type.

to check the Memory: try use rubber eraser to clean the cooper plate of the memory. then plugged it again.

in case if there is a power supply error, then try to exchange the power supply using other PC PSU.

if all steps above are checked, the problem might be at the mainboard. in that case, replacement will be the best option.

HP Pavillion won't bring monitor back from sleep mode


hi...if u can read " no input signal" from ur screen, this means that ur monitor is ok..
Look if u have power buttons on ur keyboard.. try to wake it from there.. some pc may have shortcut keys to bring back the pc... look @ ur pc docs on the internet for more info...
However if it's a hardware issue, it may be that ur RAM memory needs to be cleaned

Power supply


There wouldn't be anything from the PSU giving power to your keyboard and mouse. The mobo handles that unless your giving your mobo the wrong amount it needs which might be why your P2P and USB arn't working. Although it is odd that your mouse isn't working with P2P as that requires less power.

Wont post.


Try a few things for me OK? From what you typed, turned on the psu "the toggle switch on the psu", pc seemed to be starting up. I need you to keep the toggle switch on the power supply in the on position. Press and hold the start button on the PC case to shut it down. Give it a few seconds & power up by pressing the power switch on the case. Notice a differance? Next, unplug everything connected to the pc expect the monitor, mouse & keyboard. Try to boot. Still no? Remove the side of the case exposing the board. Turn the psu off by flipping the toggle switch on the psu, wait till the green light on the board goes out. Grab the Mb ( I know it's tight in there) and see if you can move the board in any direction. Not loose? Re-check all data & power connections for a solid connect. Re-check your case to Mb connections. Also check the PSU, there is a red slide switch it should be set to 115v. Post your findings..
