HP pavilion doesn't start up, orange light on

[Sybastian16]

Pretty awesome how the "support" comes in with the same generic answers they give to everyone with similar issues, then they fade away and disappear when they're told their bs solution from the script they're reading from doesn't work. Par for course, usual behavior of businesses big and small these days. No such thing as customer service anymore. Smfh

Same Problem...I have HP p21332 ix PC. Yesterday (15/03/17) evening I cleaned my CPU internally (both fans) also I opened the motherboard fan and replaced it again. But today (16/03/17) I am turning on the computer and the power button starts blinking 5 times along with 5 beeps and then having a pause.Mouse and Keyboard are not Responding yet.Also monitor is displaying no signal. Please tell me some solution as fast as possible.
Thank you
