G74SX shuts down in games

Hello there!

I'm new to the forums, though i've had my G74SX for about 3-4 years now.
So my problem is as follows: whenever i start playing a game my laptop completely cuts off all power. It is not a heating issue as i've cleaned out the laptop and replaced the thermal paste. Temperatures also hold up fine. I've had this issue a month ago and after trying different things with a friend who is an IT specialist we concluded that my directx files might have been corrupted and the issue has been fixed with a windows reinstall. However, the problem seems to have resurfaced. The problem occurs on both battery and while plugged in and only in games (or 3dmark).

Any suggestions are welcomed, i would like to make sure what the problem is before i reinstall my windows again.

File corruption usually ends in a crash of some sort. Not in a total blackout. That's mostly due to a power delivery failure and that means battery, charger or both usually.
Can also be a stirring problem with the motherboard in a laptop, but that's usually a life ending issue on a 3-4 year old laptop so I would try with a different charger and/or battery if you got access to that.

i have a 150W ASUS charger which i bought about 2 months ago when my old one died. Why was the issue fixed by a format then? it worked fine for a month.

How is your hard drive doing are you having any sectors repaired?
You could easily be having two separate problems, your power adapter crapped out and your hard drive is slowly crashing. Have you check it out with HD Tune or a Tool from the hard drive manufacture? When hard drive start losing sectors is usual right where all your windows files are stored.

Is that the same (or higher) wattage as the original charger for that laptop?

The problem you're describing is pretty spot on for a forced shutdown by the power delivery protection circuits. And this would happen when there's a hardware fault somewhere or if you use a to low wattage power supply. This can of course also be caused by overheating but you're saying temps are fine so I'm ignoring that.

Corrupt system files would give you endless streams of bluescreens and/or reboots (depending on Windows setting for handling BSOD and what files are busted). Hardly ever see forced shutdowns when file corruption is the cause.

And never underestimate the effect of installing software that runs in the background which causes increased power drain under load. Which can give the illusion of fixing the problem with a fresh install. 🙂

It's of a higher wattage than the original 120W.

I have also considered software running in the background, but i can't figure out what it would be.

While blacking out is a purely hardware related issue, could it be the hardware related issue slowly corrupts the software untill it becomes both? 😛

Yes, hardware failure can cause software failure, bad hardware logic or data translates directly into bad software logic or data. Bad memory or cache or mobo or signal lines or interfaces or controllers can corrupt data on an HDD/SDD which can then corrupt critical OS files and cause BSoDs (along with all sorts of other problems).

Power failures which interrupt write caches can corrupt/lose data and erode stability on a running OS. Almost unavoidable if sudden power loss forces improper shutdowns with great frequency, especially on large-flash-block NVRAM-based devices (like SSDs or SSHDs).

If it's an option, the OP (or his IT friend) should try swapping the laptop's memory and boot/system drives. Try them in another machine (with clean OS install) - see if problems follow. Try good memory/drives in the troubled laptop - see if problems vanish. Each troublesome or suspect hardware component can be tested in isolation (on a known-good platform) if necessary, until the problem is properly identified or can be properly ruled out.

hard drives are both fine, no errors. my it friend is on vacation so i'm waiting till he's back.
all i know for sure is that the issue only pops up during games/3d mark, temperatures are quite good and that a windows reinstall solved the issue for a month.

I haven't used it for awhile but I actually have a similar issue on my G74SX, when it loses power, are you immediately able to restart it? or do you need to pull the battery + plug first?
