This morning like around 9AM I decided to clean up my computer like anyone else would do. Now... I've done this multiple times and everything seemed to work fine but this time it didn't.
( I have a CYBERPOWER PC and a 6670 HD Readon along with the L-G monitor. ) everything was working fine this morning until I decided to clean up my PC.

Things I did
Opened my case up

Removed my graphics cards, RAM,CPU and my hard disk

I cleaned all the dust carefully and made sure I placed everything back in order

I tripled check to see if thy were any missing cables and everything was placed on its right position.


I plugged everything to start my PC again and this message shows now.



I've tried all the solutions today... I got 13 hours trying to figure out what wrong with it.... I even searched on this forums and tried all the solutions an yet nothing. my monitor just says the message and goes star8 black. I removed everything again and placed it and yet Nothing.. Can someone ease help me. I got important files I can't lose. Thanks

I'm on a smart phone

Hello,

Try this 1

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

are able to get the display. If the problem still exists then change the slot. If the

problem still exists then try the above procedure with the other RAM.

Remove the Graphic Card once again and place it back properly.

Good Luck.

Hello,

Does your motherboard have onboard VGA? Remove the graphic card and connect the D-Sub cable to the onboard VGA and check if you are able to get the display or not.
Also make sure that you have applied the thermal compound. Remove the old thermal compound from the CPU and from the heat sink --> Apply a little new thermal compound in the middle of the CPU and place the heat sink back properly.
Good Luck

Hello,
Try this 1
Can you hear the single beep when you have switched ON the CPU?
Does the keyboard Num Lock and LED is ON ?
Make sure that you have placed the CPU properly and the CPU FAN is running.
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".
