PC Cant Boot When Connected External HDD and DVD. HELP! [ SOLVED ]

[_Hustler_One_]

Hi everyone..

 

Please HELP!!!

 

Yesterday I bought an external DVD, and I have an unused 3.5" internal HDD which I converted to be an external HDD by using SATA to USB converter cable.

 

I connected both to my PC, then hit the power button, and my PC only blinking like there was very brief power inputs and cuts repeatedly and endlessly, its blinks like car's turn sign lamp when it's on. I tried to reseated the RAM and GPU and cooler fan and clear CMOS. Then it booted up to allow me enter BIOS, but when I finish setup the BIOS, and restarted from it, the blinks happened again.

 

Then I switched off my PSU, and disconnected the external HDD and DVD, then switch the PSU back on. This! When I swithced the PSU on, there is one of the debug LEDs was on even without I push the power button, I'm not sure if it's the CPU or the RAM because it blocked by cables and cooler fan so I cant see clearly which LED is on. (edited: it's the CPU debug LED).

I switched the PSU off again, and switched it back on, again, and that indicator LED is turned on again before I even push the power button.

 

This never happen before the external HDD and DVD.

 

I'm suspecting it's the PSU or the CPU which failed, but unsure about that..

 

Any thoughts?

Help me please..

So, find out which debug light it is.

Obvious first step to diagnosing.

Will do this right now..

@wONKEyeYEs man, it's the top LED = CPU

 

 

Dang.. This PC is less than a year with the CPU only at 4.8GHz and 1.25v with happy temps. This 8700K is complete loser silicon, I guess..

 

Can it be fixed?

You could try re-seating the CPU as a long-shot.

If you could try another CPU in that MB or that CPU in another MB that would be informative.

If this happened without you doing any recent work inside the case

and when you plugged in your USB drives I would possibly be suspect of the integrity of one of those drives.

 

Oh, you re-seated the cooler fan, CPU cooler?

You may have torqued the CPU cooler and applied undue force to the CPU.

It would be useful to know if the CPU debug light was on before you re-seated the CPU cooler fan.

 

I would want to remove the CPU and inspect for any visible damage to the contacts or pins.

Then, if finding none, re-install the CPU and cooler and test.

If you can do so gently without hurting the parts.

Everyone is different and some degree of manual dexterity is needed for this.

Yes, and no, I didn't do anything to the components before this problem happened. The problem started when I plugged the HDD and DVD via USB ports.

Not the CPU cooler, but the CPU fan cable to the CPU Fan header, just to make sure that the motherboard detects the CPU cooler as if we dont plug the CPU cooler fan onto the CPU Fan header, it might give error massage and doesnt want to boot, so I did that, and confirmed that the cooler fan is properly installed.

 

I edited the main post and add a video how the CPU debug LED turned on when I turn the PSU on and how it blinks when I push the power button.

With that quick cycling of the PSU it really makes me think of an electrical short.

 

I would check every cable and connection.

 

On the off chance that it's the case power switch you could remove the front io power connector from the MB and short those two pins with a little screwdriver or something

to start the PC.

 

Because of the debug light for CPU I would want to inspect pins on MB and contact pads on CPU for damage.

 

It could be so many things at this point.

Could be the PSU, do you have another?

You should try removing the GPU and running off the onboard.

Could be a short somewhere. Check everything inside.

 

I'm not a tech, maybe one will show up.

 

It is also advisable if you don't know the prob to remove everything from the MB except the 20/24 pin and 4/8 pin, one RAM, boot drive, CPU and cooler, CMOS battery.

Remove all the front io connectors and boot by shorting the two power pins as I said above.

This gets things as simple as possible.

If the board boots without the power cycling then start adding components and cables one at a time.

@wONKEyeYEs so I found this, I tried to unplug the PSU power cable from the socket, and plugged it back, and switch the PSU on, and that CPU debug LED doesnt turn on, and PC booted to windows and I can use it, "BUT" when I tried to properly restart from windows, the blinks happened again.. WTH happen to my PC? I'm clueless here..

Will try your suggestion and wait for another solution from other people here..

Hey, it's working! Praise the PC Master Race Gods.

Does the PC start from a shutdown state but not when you do a Windows restart?

Or do you also have to interrupt power at the PSU?

No it still have same issue, but this time, everytime I unplug the power cable from power socket and plug it back on, turn the PSU on, it boot to windows, but when I restarted either from windows or shutdown state without replugging the power cable on its socket, the problem reappears.

To my limited knowledge, it could still be many things.

Maybe PSU or MB?

At least it still functions though eh?

Unplugging from the wall and flipping the PSU power switch is probably redundant.

Try just flipping the PSU switch, pushing the PC case power button to discharge caps, and flipping the PSU power switch back on and boot.

@wONKEyeYEs Tried to replugging all the cables which connects to motherboard, still cant fix the problem.

[_Hustler_One_]

Bump!

 

Anyone, my PC can boot only if I replugging the PSU power chord on the house power socket, with or without UPS, is the same. So I'm suspecting it's the PSU problem, but can anyone help me to confirm it? But I don't have a backup PSU to test..

[_Hustler_One_]

@wONKEyeYEs I found the real suspect! It was the fking DP cable! I'm not joking.

 

I was tried to check all the cable connections on the rear I/O panel, and ended up found the DP cable affected this problem.

When I took the DP cable off the CPU debug LED light is gone, and I was like "WUT?! SERIOUSLY???" then I connected the DP cable back on, the CPU debug LED light turn back on..

 

Why such a display cable can affect the motherboard to turn the CPU debug light indicator and doesn't allow the system to boot?

 

I was about to RMA the PSU but this finding relieved me.. 

Then I swapped the DP cable to a DVI, and this problem disappeared..

 

a DP cable... WTH..
