Question

Computer shutting off. (not overheating)

I just recently started having this issue where my computer shuts off completely when trying to load Leauge of Legends (it happens at other times but mostly while in game or right when pre game lobby is over). Once the computer shuts off and when i go to turn it back on it normally shuts down right after windows chimes. After that it will load just to desktop just fine. I recently just installed a fresh version of windows 7 ultimate, I have made sure to download all potential drivers and update all windows files. I troubleshot while in a custom game by lowering my in game setttings from medium to low and when doing so my computer instantly shut down after going from medium high to low setting. I'd like to think it is the gpu but from all the forums ive been reading it could be a whole list of different issues. my specs are
Ta970 5.2 mobo
AMD FX-6300
nvidia gtx 560 ti
Corsair Vengeance Blue 4GBx2
samsung ssd 840 (THE OS IS ON THIS)
Hitachi HDT725050VLA380
Rosewill RG630-S12

Never rule out heat.

In reply to: Computer shutting off. (not overheating)

After decades in repair, you ignore any lines like "not heat". You just run into heat issues where a chip or board that has become heat sensitive. That is, when new a board can run at extend temps. Years pass and it won't. It's that simple.

The build looks very old. You have to ignore the not heat then treat it for new heatsink compound and cleaning. A fan test is made than you leave the cover off and see if it stands up to testing.

The shutdown on high game settings often points to GPU, PSU or motherboard issues. Which part can you change first?

https://www.newegg.com/Product/Product.aspx?Item=N82E16817182200 has mixed reviews but it seems to be a nice enough single rail so it's lower on my list. Try GPU then motherboard.

Sadly nothing.

Currently I do not have any extra parts (gpu, psu or mobo) to swap out to see if that would fix the issue. If I did I don't think I'd be posting here. I understand that it is more then likely a hardware issue but is there anyway it could be software? I have only had this issue really since updating my OS, now that i think of it i did update my BIOS and right after i had a cmos failure, so I bought a new battery and that fixed that but the shutting down started to happen more frequently in just the past 2-3 days. I have had points where I played hours (since its been shutting down) of league of legends, but lately I cant last more then 25 minutes in a game. I have cleaned my entire computer out and im making sure (using Open Hardware monitor) that it is not getting too hot. If it comes down to replacing the hardware so if thats the case ill go with GPU first then the motherboard.

To test the software

In reply to: Sadly nothing.

We slip in another drive and do a quick install. This way we have a clean build without any doubt about OS and drivers. Remember this is our method in the shop when we suspect software.

Remember, hot is not the cause in many cases. It's just some part that can't take stress like it used to. In the shop we have spares for PSU, GPU and a few CPUs, RAM and not much else. But to do PC repair you have to have spares as the industry never perfected testing by any other means.

(NT) Might have solved my issue.

Woops

In reply to: To test the software

Did not mean to post just that title. Any ways, personally thinking that my issue was GPU related, a while ago my case was slightly bent in the moving process. I hooked my computer up outside of the case and since ive done so (45 minutes now) I havent had any issues at all. I played a custom game of league of legends (no other players just me, on medium settings). I was able to play the entire 30 minutes of the game. Now I'm typing this to ask, would my computer have been resetting due to my case somehow? I've read just recently someone having this issue, if this is the cause to my issue that would be good, a case is a lot cheaper then a psu,gpu or cpu. Also what would be the best possible case to use (under $75) for my hardware? Which again is
Ta970 5.2 mobo
AMD FX-6300
nvidia gtx 560 ti
Corsair Vengeance Blue 4GBx2
samsung ssd 840
Hitachi HDT725050VLA380

Yes.

In reply to: Woops

I've seen bent cases interfere with seating of cards. Also found way too many extra motherboard mounting posts that short it out.

What gets most folk is "it worked for years. It can't be that." After hundreds of such statements you nod and dive into the work.

Another thing. Outside the case you are getting every part maximum cooling. If a part has become heat sensitive (not overheating) then a stuffy case can cause issues to return.

Gaming pitfalls

In reply to: Computer shutting off. (not overheating)

As Robert stated heat is too often the bad thing. Damage is done but may not be noticeable. Its already too late as somewhere its compromised a component. GPU or CPU, thus be sure the cooling is active and well within specs. Alas, swapping parts is about the the only fix that says, you got it. I suggest you remove GPU and CPU entirely and blow-out the innards and regrease. If you can reduce gaming demands and see if it lasts longer. Gaming when done constantly and using basic cooling or having cooling get less than desired will wreak havoc. Don't forget the case as well to be clean out to include buried fans.
