View Full Version : The G75VW Random Shutdown Mystery not Solved

I got my G75VW back a few months after it first came out and for years, until now, I've been suffering from a seemingly random shutdown/powerloss reboot. No matter what the computer was doing, playing games, at the windows login screen, browsing the web, occasionally it would shut down as if the cord was unplugged and battery removed.

Other users have solved this by disabling hibernation and uninstalling certain ASUS programs, I've done all that. Like everyone else, no problems show up in event log. I've reinstalled and uninstalled USB 3 drivers.

I have now found the solution. My USB ports.
With anything plugged into my computer via USB in any port other than the non-powered usb on the right side of the computer, my computer will ALWAYS reboot within 1 day, at the best of time, every 30 minutes or so at the worst.

So, I've diagnosed the problem, finally after 2 or 3 years. I have no idea where to begin solving it, or even if it is solvable at all. If anyone has any ideas, please point me in the right direction. Thank you!

TL;DR - Computer crashes randomly when anything is connected to any USB port other than one. Ideas?

Is your computer still up and running?

This trick didn't help me though :(

Yeah. As long as I only have one thing plugged into the computer in the front-right usb and nowhere else, its fine. Otherwise it always crashes. I recently had to reformat a 3TB exD that went read-only because it crashed in the middle of copying.

I remember having sudden shut-downs (I mean like having sudden power outage) and they told me that they could not reproduce that in their service center. I forced them to change the motherboard and since I had never this problem.

Aliasmk,

I also have a G75VW with random shutdown issues (only on battery though) and am looking for some clarification from your post.

Concerning your statement:


USB in any port other than the non-powered usb on the right side of the computer

What do you mean by "non-powered usb" exactly? My front right USB is my USB Charger+ port...is that the one you mean?

Thanks!

UPDATE: The computer just crashed twice in 2 hours, the only thing plugged in was the mouse, in the port that was working before. I'm so done with this, USB broken, DVD drive broken, horizontal lines on the screen, I just want to RMA it.

Anyone have any experience with RMA? Ie: how much did it cost, how long did it take?

Sorry for the late reply. On the right side of my computer there are two usb ports. One has a little lightning bolt next to it, the other doesnt. I presume the lightning bolt one is powered while the computer is off but idk, never used it. the point is the only usb port that didnt trigger the crash for me was the one with out a bolt (the one closesed to the Minidisplay port. However, please see my edit.

I seemed to have fixed the problem... I've basically always used my computer plugged in on the High Performance battery setting. I decided to try it on Balanced, and sure enough, for the past week I've had all 4 USB's plugged in, and not one crash.

Update: 2 weeks later and its started crashing again. No idea why. I'm about ready to let gravity do the "fixing", unless RMA is cheaper than I think it is.

I have the same issues. It's a gpu issue or something, or a power supply thing i dont know.

I found a fix for my machine. First of all downloading the latest BIOS driver from asus site helped. Then download msi afterburner or some other clock program and UNDERCLOCK your GPU. I set mine to 365 Mhz (the minimum) and I get guaranteed no crashes.

But it really sucks because I can't play any games now, I have to stick to the lowest graphical settings, in games like WoW and League these settings look like crap, and the whole reason I bought a 2000+ dollar laptop was so I could play at max settings on the go... Such a shame.

Anyway turning up the core clock to about 450 or more and then playing a game or even doing random tasks cuts the power from the computer.. great. At least most of the computer is functional, you just have to stick to the lower settings. Hopefully that might help some of you guys.

I seem to be having the same issue. The laptop only shuts down during gaming so while charblaze's solution might work, i'm not willing to turn my gaming laptop in a facebook machine. I'm still testing if it works while usbs are unplugged. I'll update it when i've done more testing. But i'm 90% sure that usbs are the only explanation as i've given my laptop to IT friends and they couldn't get it to turn off.

There's definitely something wrong with the USBs, it works fine without anything plugged, or with just my mouse in the usb 3.0 port, (i have a g74sx so i have 3x USB 2.0 and one 3.0). It won't boot my usb stick with windows 7 on it and when trying to print things it gives communication errors with the printer even though it ends up printing fine.

I still find it weird that the shut down only triggers during gaming or heavy video card usage i guess?

The question is how do we fix it :-(

Mine crashes regardless of any load on the system other than pure idle, which i've never observed it crash under.
Its very likely a power issue, which is why charblaze's solution worked. I'm not willing to underclock either though.

Right now I just want to sell it and be done with it, but I cant sell a crashing laptop with a randomly defective DVD drive.

Edit: It would be nice if we didnt get auto throttling when on battery power because then we could see if its the power jack generating some weird voltages. But throttling would take care of that in the same way underclocking would.

My laptop died completely and would not power on. The light would turn on for a millisecond and then nothing. I assumed that the usbs might be fried and the laptop is not cutting power when turned on as a fail switch to not further damage the motherboard.

I've sent the laptop to ASUS romania for repairs and they told me i need a new motherboard. Somehow i doubt that the issue couldn't be fixed and that the motherboard is 100% dead. I'm sure it's convenient to just ask for 600 euros for a new motherboard and be done with it.

I'm annoyed that i bought a new charger for it which costed about 100 euros and 8gb and ram and it died less then a month later. I'm also not willing to spend that much money to revive a 4 year old laptop

Any opinions or suggestions are welcomed. Man i'm pissed right now

This sounds really scary. Are you saying this happened after disabling BD-PROCHOT with Throttlestop?

EDIT: Oops.. I was thinking of another thread... Did anything out of the ordinary happen before it died?

Update: Disabling BD-PROCHOT as advised my other threads does not fix the problem, laptop crashed on idle an hour after playing for a few hours. Temps are not an issue, throttle stop reported maximum of 70 degrees last time I checked before the crash.
Back to square ****ing one. Only thing that really works to solve is only plugging in one USB.

i have this exact same issue...
it all started suddenly after maybe 1~2 years of use
seems users everywhere in the world are having this issue!
i installed MSI afterburner and lowered the core clock to 400Mhz
and it helps to avoid the random shut down i say by 80%
still 20% of the time, i get random shut downs, during game, during chrome
the question i have is that
why does this problem only surface after maybe 1~2 years of use???
and once it started, there's no way to return to normal?
people are saying it's GPU and the motherboard
but some say after replacing with a new motherboard the problem still persists
i really don't want to dump this expensive machine only after 3 years...
how could ASUS put such product onto the market?!

Hi there,

Have been experiencing the same issue as yourself. So far only work around is to underclock the gfx card however that does not appear to be the issue. I have been working closely with a motherboard component repair specialist to try and isolate the issue. Based on your previous post about the machine not being able to turn on straight away after a hard shutdown is a symptom of the cpu overheating. I haven't reapplied thermal paste to the cpu/gfx card heatsink just yet. That will be something I will be doing in the coming days but should I come across the root cause of the issue I shall post it here.
