When i turn my cpu on, my computer screen stays black with a blinking green light.
its a monitor signal cable issue because before i could twist the open end of monitor signal cable around and get a glimpse of the picture on my screen. but now even that wont happen and the screen stays blank.
so what do i do? do i need a new signal cable? can i repair the present one?

Re: monitor signal cable troubleshooting
Hi, there is some loose contact in the connection. Take out the cable end from the VGA socket and check the pins inside the socket for any bend inside the socket. Reconnect it, tight the connector with the socket bolts. If not solved, try for any loose solder or wire breake.

I disagree with ikkenom only due to the symptom of the flashing blue light. This would indicate to me that the monitor is not getting any display signal and is in sleep mode at least the is what happens on my Samsung monitor. Used to be that they use a two color led in the monitor, green when ON and getting display signal and amber or orange when in sleep mode. I would check the computer by trying a different monitor. If you have a second monitor, great, if not, maybe a friend will let you bring your computer over and try the computer with their monitor. Could also be a display adapter setting. Do you get any change when you first turn on your computer? i.e. Do you get the BIOS or manufacturer screen when first turned on? Also if you disconnect the monitor cable from the computer and power cycle the monitor, do you get a No Signal display for a few seconds before the monitor goes black and the blue light starts flashing?
Let me know what happens with the testing above or if you need further instructions to carry out testing.
First make sure that all the cords are connected properly from the back of the CPU to your Monitor.I suggest you to unplug all the cords of the CPU and then plug them back in after 10min. and make sure they are all connected tightly.Next check if the power cord connected to the Monitor is attached tightly.
If you still face the problem then you will have to replace it with a new power cord whih connects the CPU to your Monitor.It is black in colour.
remove themonitor cable from the cpu and see wether there is no connection mentiond in the screen if you have so then remove the cover of the desktop and remove the ram and clean them and still the cpu is not working then change the ram
Generally Monitors have a single light in fron pannel, with dual mode colors as Green and Orange.
Green: Everything is OK .
Orange: Everything is OK, except it is not getting
any signals from computer or other source.
Try with any other monitor with your CPU, it may happen that CPU actually not providing any signal to Monitor. Try checking the "NUM LOCK" button on and off, whether it makes the light on keyboard to flash on or off.
If NUM LOCK is woking OK, there is surely some problme with your monitor and you need to get is checked physically with an engineer.
