fter connecting the AC power supply to CPU and on pressing start button , CPU light does not blink spontaneously ,It took 3 to 5 minutes to start blinking and window start immediately as light start blinking on start button .Reliability report does not show any error.Pl suggest me some remedial action
Ehm, CPU is "central processing unit", a computer component. It does not have a light linked to its operation. If by CPU you mean the whole machine, call it "computer".
If that led is close to a symbol that resembles a lightbulb, then it's the power led, and tells if your computer is actually getting power or not. It should go on when you press the power switch and remain on until you shut down the computer.
If it is close to a cylinder symbol, it is the memory usage led, and tells if your computer is reading from its main internal memory device. It does blink randomly when in normal operation and if you don't experience other issues you can safely disregard it.
Other leds can indicate the wifi connection or whatever the maufacturer thought to place there, if it's not one of the above, try to describe it or find an image of it from google.
Please follow this tutorial to fill your system specs (step 7 to do it automatically), so we can know what is the thing you have in your hands. Without knowing more, help provided will be limited.

Those lights if I understand what your writing correctly is nothing you have to worry about as stated in the post above yours it only indicates hdd activity and memory, so they wont light up or blink if nothing is being used.
My computer does not start at all as it took 3 to 5 minutes to start after pressing the power button .Any solution
Question; when it does come on does it function normally?
After pressing the power button ,computer start after 3 to 5 minutes ,once computer start,it boot up in normal way and their after it function normally
It sounds like you have a lot of background programs starting up or it could be a virus that causing the slow bootup, have you scanned for virus lately?
I am using Norton Anti virus2013 and full scan is carried out once a week and i disabled all services during start up
Actually, it sounds like there's a problem even getting the computer to reach the BIOS part of the bootup. Try using another outlet, it could also be a failing system board or power supply. Are there any noises or lights at all when you press the power button?
