Hello guys, I'm building a new rig for my friend and it keeps rebooting randomly. Once it reboots it would sometimes reboot 2-3 times immediately. Sometimes none, it reboot once after 1.5 hours and it's been about 6 hours since the last reboot.
The cpu runs low around 38C-55C at most
The gpu runs at 50C-70C

Build is here: https://pcpartpicker.com/list/4JDzTH

Edit: I also unchecked auto restart on system failure, but it still doesn't go to the blue screen.
Also ran stress tests on cpu and ram and works fine. I swapped my duke and his duke and everything is normal too. I'm speculating the problem might be the psu, but not sure.

I had a similar problem when i had a shit-tier PSU. It simply could not deliver enough power to the GPU, so there would be power dips and the PC would randomly restart.

However, you seem to have a good PSU in your build. Maybe it is slightly broken, or maybe some power cables might be slightly loose?

What Simberto said, I would add: run memtest for minimum two full runs, optimally for a whole day/night.

Random reboots/lock ups could definitely be a power issue.

In Germany, most 1800 and 1600 rams are cheaper than 1333. It's ok if i buy that and use it without OC? I have no clue how to OC.
edit: I have 2x2GB 1333 CL9, but I want to upgrade. There are 2 slots free. All local shops offer 1x4GB 1333 CL11. I haven't looked about 1600 and 1800 timings.
I also can buy 2x4GB CL11, install them and remove the 7 yrs old CL9 rams.

Should be fine; it'll default to the lowest usable setting. OCing it is a pretty simple process though. Just google for a guide to see the jist of it.

As a gamer, you should only look into Mhz speed, since CL (Cas Latency) has little to no impact on performance for these types of things.

It depends on the game as to if they'll scale with bandwidth and/or latency

Lower latency also lets the RAM start a transfer earlier - a 2133c9 kit will outperform a 2400c11 for bandwidth across a certain range of transfer sizes. The 2400 has more theoretical bandwidth but the 2133c9 starts the job earlier and small transfers are finished before the 2400 has enough time to catch up and overtake it, leading to a lower achieved GB/s score for the 2400. It's important to somewhat balance latency & bandwidth for general use if you're optimizing that sort of thing

Ok, thanks guys. He used the computer all day today and didn't have a single restart. I told him he should run more tests anyway, but he said it's fine.

It seems I must OC my mainboard and not my RAMs? Google gives me a headache about OC. It seems that all OC guides is about how to maximize the RAMs performance.
I only need that nonOC 1800/1600mhz Rams are working on 1333 slots at mainboard.

The (OC) part is about overclocking the CPU memory controller. They should just default to 1333 AFAIK

What would you do if you want to upgrade from 4GB to 8GB Ram? You have 2x2GB 1333 CL9 in your pc,you are not going to OC and you still have 2 free ram slots. 1333/1600/1800 have the same price. Considering that all local shops only offer 1333 CL11 nowadays.
Just try to buy 1600 CL9? then it works like 1333 CL9?

hi
i'm making this posti nside this thread not to polute the forum with another (maybe) simple thread.
Apparently my computer is infected by this trojan "win32.lnk" which is located in this location:

C:\USERS\USERNAME\APPDATA\ROAMING\MICROSOFT\WINDOWS\START MENU\PROGRAMS\STARTUP\WIN32.LNK

I used malwarebytes to remove it twice in a row and after rebooting everything is working fine. The problem is that both the trojan and the problem are back again after just a few minutes. Can any of you help me get rid of it for good? This little fella is annoying the shit out of me because it's preventing me from using Brazilian accents* when i'm texting.

I'm getting [ ~~a~~a~~aaaaaaaa~~a ] instead of [ ããããããããããããããããããããã ].

Currently using windows 10 and all keyboard and language setups are fine. Thanks.

*is that the same word for language signs as it is for language speaking habits?

Did you try cleaning it in Safe Mode?

I think so. Normally you have to relax the timings when you're going up in Mhz (OC), but I don't think that applies going down.

IMO it's really hard to gauge the difference CL9 vs CL11 actually makes. Probably you wouldn't even be able to notice the difference.

Hi guys need help on this one, my PC sometimes randomly reboots and displays a weird screen with random colours. It's 6-7 years old and probably one of the parts is dying but not sure which. Anyone knows what is this and which part I need to replace? Thanks in advance!

More info makes things easier to diagnose.

Memtest86 will show you if it is the RAM. Watching HWMonitor will tell you if you have problems with your temperatures. Run some pressure tests like Furmark or something.

Weird colours suggest maybe graphics card. Do you have access to any other graphics card to test if the problem persists if you exchange it?

Other than that, you really don't tell us enough to diagnose anything.

I currently have an iPhone 5s and want to upgrade... Do I wait until Sept/Oct until the iPhone 8/Google Pixel 2 comes out to buy a new phone or is it okay to buy now? And at that point, should I switch over and try Android on the Pixel?

Really depends on your budget / wishes.

For me Samsung and Apple phones are just way too overpriced. The Google Pixel also feels that same way (note; I've been using the LG Nexus 5 and LG Nexus 5x the past years and I'm a huge fan of Google phones).

Me and a friend just bought the Xiaomi Mi Mix for 450$, which is an high-end phone from China. Xiaomi has been delivering more and more superb quality phones the past few years for a fraction of the price of the high end Samsung / Apple models. I'd like to recommend the phone already, however I must say that I haven't even received it yet.

If you're really hooked on iOS, stay on iOS, but for me personally, there will never come a day that I would buy the newest iphone and/or samsung for 900$+. It's just too much for mediocre* phones.

*with mediocre I mean cost/performance wise, I'm well aware that these are the most powerfull phones on the planet.

I like that response. I agree with the sentiment that they are overpriced, as people are willing to drop that much on a phone that they'll use for two years. I can maybe justify spending $750, but I'd prefer not to... Currently, I know Verizon is having a promotion where, the Galaxy S8 is only $420 ($750 for ATT and Sprint). Unfortunately, I have ATT right now.

Can you provide more details on the Xiomi Mi Mix? I'm apprehensive on trying a brand, especially from China, that I've never heard before. Are there good reviews?

I know just 1 person in real life who owns a Xiaomi, he is really satisfied with it.
A couple other friends of me (one is the guy who now bought it aswell) follow the phone industry much much more than me and they have been quite fond of Xiaomi over the years, but just for specs vs price.
Xiaomi is the market leader in China and other parts of Asia in smartphones.

I'm a bit of a newb when it comes to phones, so I'm not the best person to ask, but here's some different phones and reviews : https://www.androidcentral.com/these-are-top-xiaomi-phones-you-need-know .
The Mi Mix is really big, so might not be for everyone (about the same as the iPhone 7 Plus in size, but 6,4" instead of 5,5" due to his superior screen-to-body ratio).

Aw, to be honest I can't comfortable hold giant phones with my baby hands

Appreciate the response though
