Hp SFF 6300 didn't Boot at once

[Mohit0033]

Dear HP,

I have been using my HP SFF 6300 equiped With Intel I5 3270s and 8GB DDR3 RAM. I am facing one problem since last 5 days when I start my PC at Morning it turns of immediately and start looping couple of times but after some time The fans start moving At full Speed with no beep and red Light and power light stays green then I am forced to directly turn off mains and after that it start and booted.

The next day same.

The other day I hv decided to turn off the mains for whole night but the same problem on next morning.

If some one can help me it would be really appreciated

When the motherboard is powered-on, it runs the fans at 100% speed (and noise), until it finishes the POST (Power On Self Tests). When the POST has successfully completed, and the temperature of the motherboard and the processor are in the "normal" operating range, the motherboard instructs the fans to slow down (and get quieter).

So, it is probable that the POST either never was launched, or that it has not successfully completed.

The fact that your second try to boot is successful implies something "intermittent", such as a "marginal" electronic connection (inside the motherboard?) that fails when the computer is "cold", but is OK when the computer has warmed-up.

If the HP Warranty is still valid, then contact HP Support. Otherwise, find a qualified computer technician, for professional trouble-shooting.

Sadly the product is out of warranty.

Now today it starts at one click but turning off itself I am frustrated with it as it is keep turning off in middle.

I tried other power cord from other pc also, same problem and tried other power outlet available in my home still the same issue.

maybe it PSU issue?

Or mobo issue I can't try other PSU though coz of that proprietary PSU Connector in HP SFF 6300. I have standard extra PSU with 24pin connector and as I am in India the idle temperature remain 25 C on the room where PC Sits.
