Hello,

Try this 1

If you notice that your CPU fan is running but there is no display in the screen,

then remove the RAM from the slot, clean it and place it back properly or try

another slot.

If you have no idea about RAM, then click on the below hyperlinks "Images".

RAM

Removing a RAM

Check your RAM also. Even bad RAM will result in display problem.

If you are having two RAMs then remove it, place only one RAM and check the

display. If you failed to get any display then change the slot. If you still failed to

get the display then try the above procedure with the other RAM.

Good Luck

Thank you, jack4rall 4

Hi birukadu,

"2 blinks followed by a short pause, 1 blink, long pause, then repeats", this pattern indicates "Bad Motherboard". The motherboard in the computer needs to be replaced.

i shut the PC down forcefully and try to start I gain for few times, but finally the PC stop start (like dead) the fan also stop. only the power on button blinks red light. even after I remove the power cable, the red light blinks for around 30 sec.
and when I touch some external part of the PC it has a little shock.
this is not the first time when I try to change the hardware, I always discharge myself b4 making any change. this is so strange to me

Hi birukadu,

The OptiPlex 7010 supports either integrated graphics or add-in graphics card. What is the graphics option in your machine? If you have add-in graphics card, please try to re-seat the video card and check if you can obtain video on the screen. Refer to the Service Manual for Safety Instructions and removal steps.

Do reply with results.

Hi birukadu,

You have mentioned that the Power button is blinking red, this indicates a failure condition indeed. The power LED always blinks in a pattern. The pattern is 2 or 3 blinks followed by a short pause then X number of blinks up to 7. The repeated pattern has a long pause inserted in the middle. Example 2, 3 = 2 amber blinks, short pause, 3 amber blinks followed by long pause then repeats. Please reply with the exact pattern that you observe.

Hello,
Try this 1
Try to reset your CMOS settings.
Turn off your PC and remove the power chord --> Open the cabinet --> Remove the CMOS battery for 15-30 minutes and then put it back properly. Now plug the power cord back in and switch ON your PC.
Click on the below hyperlink "CMOS Battery" if you don't have any idea about the CMOS battery
CMOS Battery
If the problem still exist, click on the below link and follow the instructions in "Hardware Reset".
