Re: Computer troubles...
Bad BIOS would be my first guess, short on CPU VRM would be my second, dead chipset would be the third.

Re: Computer troubles...
No, it only powers up for about 3 seconds and during that time there's no video. There's barely enough time for the CPU fan to start spinning.
It's like one of the very first checks is failing.Leave a comment:

Re: Computer troubles...
simple test,
if you go into the bios settings - does it stay on?
my one did - it was only when the o.s. started ramping up the system that it doed.Leave a comment:

Re: Computer troubles...
i have seen a bad cpu do that.
i think it had a short in a section that is not active at boot.Leave a comment:

Computer troubles...
My home PC is giving me some trouble, it's not booting up properly.
The power cycles on and off continuously. It doesn't show any signs of activity and only turns on for about 3 seconds before turning off for one, then repeats this cycle continuously. I have bench tested the power supply and that seems OK. It stays on when PS ON is held low. I've also scoped the rails on the outputs and they seem reasonable when under normal load, 12V at 12.2V, 5V at 5.09V, 3.3V at 3.37V. I'm thinking it's the motherboard, which is a Gigabyte Z97X-UD3H.
Does anyone have any experience of this issue?
Have done the obvious, like disconnecting all peripherals and drives, all fans, and running with only one stick of RAM. Will try another PSU just in case, also need to reset the CMOS or maybe use the backup BIOS flash on the board (apparently it has two).
Took power supply apart (EVGA NEX650G), no bad capacitors visible.Last edited by tom66; 02-08-2018, 02:03 AM.

lenovo l490 esc light is continuously on and no display what to do ?... -
As the Elitebooks (820, 840 all gens) only show flashing Power LED and flashing CapsLock (continuously) + a very soft "ticking" noise near the DC Jack,
I wonder if re-flashing the BIOS might be of any use here.
As far as I understood, steady flashing either means insufficient power or a CPU/GPU/Motherboard issue. I use the original 65watt power supply.
There are so many threads out there, but most of the solutions involve flashing codes, which I dont have or claim that you MUST use the original power supply, do a hard reset, reseat the RAM, clean the RAM,... -
hey all,
i have this board earlier it was dead no power i changed the smc and all worked fine.Then after 5 days the customer gave back with it stuck on sleep mode.
so i checked the rams then checked all voltages they are all fine.Put another smc and also programmed the bios.Still same issue.the funny part is when i remove the rams i get long beeps indicating no ram, but still the sleep led is on continuously.I get plt_rst 3.3V ok.also LPC_ad0 ,ad1 ad2 ad3 all communicating. also i see bios communicating.
I just narrow it to 2 issues now pch or cpu has anyone faced this problem...10-19-2023, 08:17 AM
