After switch on CPU have a delay around 3 to 5 minutes and then booting my system, please hep

[sm5]

Thanks in advance.

When I switch on my power in mother board I am able to see the stand by light is on, then if I switch on the cpu power button its taking some time 3 to 4 min to boot.

But there wont be any issue if shutdown and switch on again my cpu. Once the main power switch is off and then on the problem arises. Help me experts.

i tried by removing the ram as well, the same issue.

details of mother board and processor:

Computer Manufacturer :Intel Corporation

Computer Model :DH67CLSystem RAM :16 GB

processor Model:Intel(R) Core(TM) i3-2100 CPU @ 3.10GHz

CPU Speed:3.1 GHz

• Power disconnected
• Unplug your DVD and any unnecessary USB devices.
• Power connected
• Then try booting again

I am betting on the DVD.
