Title: Tech gurus assemble, I need your opinion. [PC]
Post by: Christo on September 16, 2013, 09:08:29 pm
So, after my PC survived and got home, things were all fun and games, until..
My PC isn't powering on normally anymore. Now, I've been reading some articles and threads about this, but the weird thing is, it's completely random.
Last time it happened about a week ago, I used the PC the night before, woke up in the morning, fired it up.. nothing. Green led up, but no response. Came back home later in the evening, it turned on for the first try.
Today is the same thing, I did everything usual, played for some hours etc, no problems, then shut it off and went to sleep. Turning PC on early morning to read some news, nothing. Nothing ever since.
The weird thing is that I know it can give power, I used it for weeks with this setup and gamed heavily for hours. So the hell is it's problem? This is what I could use some insight for, I only had the exact opposite with a dying PC years ago, it didn't want to turn OFF, and always turned on in the middle of the night, waking me from sleep. That was a bit creepy back then though lol.

I had a similar issue recently where I knew I had power going through the computer (Motherboard LEDs were lighting up to signify power flow) but it wouldn't want to boot up. That was something to do with the power supply failing to have a continued charge as I never switched the plug off, it was still getting a current which may have buggered it up.
Anyway, the next time I shut the power off from the mains, it wouldn't turn on at all, I had to buy a new power supply and since then it's worked fine.
In short, I honestly am quite lax on the whole hardware past how it all fits together & the maths on the back end of it, but I would hazard a guess that the power supply is giving up the ghost...

Does sound like a power supply failing to me...
I have had two power supplies fail in the past, and in both instances they had problems leading up to the ultimate failure (they never actually "failed" completely, one was arching and sparking towards the end so it was obvious it was shot, the other would power off randomly, which was probably just due to not enough power for my PC...so maybe just one failure I've had).
But in the one that failed, it would turn off intermittently, and it would also work just fine at other times.
Only way to really know if that's your prob is to replace with another power supply.

Balls, this power supply supposed to be the "replacement" I scrapped from my ancient PC after mine gave up on life recently.
Fuck. My. Life.

Well if that's the case, I'd be less likely to think it was failing or somehow not working properly, as I would tend to think it's just not powerful enough for your system.

Both were the same wattage though, at least on paper.

How did your first one "fail"? Like what symptoms were you experiencing?
The fact it won't turn on sometimes is not a good sign IMO (I think if it was just not powerful enough it would turn off at certain times, but not expect it to fail to turn on the system).

Wait.....you took a PSU from an ancient PC which belongs to a technological museum as a relic of the past and put it into a PC of a newer date ? :rolleyes:

PSU is a pretty safe bet. Could also be the power switch, though, but if you say you can see the leds of the mainboard going on and fans spinning, probably not. Some mainboards have failure beeps/led flashing combinations, do you have anything of the sort?

Is there any beeping? If it's RAM it does this beep, otherwise I'd say PSU. Worst case it's your mobo

Nope, nothing spins up. Dead silence. No POST-apocalyptic beeps either. hue
Also I've tried swapping power switch with reset, nothing, the screwdriver trick doesn't do anything either. Only way is if it randomly happens, lol #RNG_PC_yolo

Sometimes, when power supplies fail, although they used to deliver enough current, they just break down at a certain threshhold. That means the power supply can deliver a little bit of current but when the computer (or anything else) connected to it starts to get thirsty the power supply "crashes". I've mostly experienced this with low-quality power supplies though.

I suggest you don't touch the system anymore until you have a new PSU. Wouldn't want to damage any other components in the process.

ive had this issue some times but never the same solution.
one fix was i disassembled the entire computer and put it toghter again and it fixed it. i still dont know what was wrong. but this is just typical :)
another time i think i used older PSU with too many HDD's (not ssd) it started to act like you descripe. i tried disassemble. didnt work. then i disabled all drives apart from the C: HDD and that fixed it.
theres so many reasons, first id disassemble your comp and put it toghter again making sure all plugs and cables are connected correctly. if it still have same issue, id disable all the devices that you dont need for the comp to start up, like CDROMS, extra HDDs and so on. if you have on-board GPU then disable your graphics card as well.
if problem STILL persist, yeah then id say PSU game over OR you need to dust it off :)

1. Make sure the last speck of dust is removed from everywhere, specially inside the PSU 2. Put a little bit of oil on the fans while you're at it, also inside the PSU 3. If it doesn't start at the first try, get a new PSU. Choose a proper brand unless you want to change again soon.

Yeah I'll try to disassemble everything, then decide what to do.
Also looking at what PSU I might get, limits are the skies as usual, lol
Seeing some industrial junk being sold for 6-8 euros is just hilarious

Actually, the tip about disassembling and reassembling is worth a try, since it might be a loose cable somewhere. Also, if you disassemble the PSU, be careful, there can be charged parts for quite some time after you have debranched it.
