First Time Build Stability Issues and Random Restarts - i5 4670k - Please Help Troubleshoot

Hello everyone,

So this past weekend I completed my first computer build, and have had a few issues that I cannot seem to get resolved. Here are my system specs:

CPU: Intel i5 4670k
CPU Cooler: Hyper 212 EVO
Mobo: MSI Z87-G45
GPU: Gigabyte 7950
RAM: 8GB Vengeance LP
PSU: Corsair CX750M
Case: Corsair Carbide 500R
SSD: Samsung 840 250GB
HDD: Hitachi 1TB

This particular issue has happened about 3 times while gaming since I completed the build, and each time has required me to reinstall my Killer internet drivers to get internet back again. So, basically I will have been gaming for a few hours and the computer will suddenly shut down, reboot, and then cannot access the internet anymore. I have been monitoring the temperatures of the system with HWInfo and cannot pin-point the problem. I thought at first that it might be the CPU cooler, so I completely removed and re-added the 212 EVO last night. But again, after a few hours today the system crashed on me again and when it rebooted, it could not access the internet until I removed the internet driver and then reinstalled it from the mobo CD.

Please, please, please help me find the issue to this. If absolutely necessary, I might need to completley reinstall Windows, but I would obviously only do this as a last resort. I just cannot find out why the computer seems to crash randomly, and then reboot and not have internet. Thanks for reading and I appreciate any help with this!!

I had this same problem on a windows 8 computer. It turned out to be a bad Ram module. Try running each module separately and see what happens. It could also be a driver compatibility issue for your network adapter.

Do you mean the actual RAM sticks? Or just the modules that they are installed into? I know that I had issues when installing Windows with my RAM. I had to install Windows with just 1 4GB stick. And when I installed both sticks, I had to change the frequency from 1600 to 1333 to get it to be stable. So, could it possibly be bad RAM sticks, the RAM slots on mobo, or both?

Also, I am curious if it could be a power supply issue. I went ahead and ordered a different, better power supply (the HX750) to swap those out and see if I'm still having the same issue.

I also saw in another thread that I should try plugging the cord directly into wall socket and not into a surge protected power strip.

I'll look into the RAM issue, and I'm going to swap out the power supply this weekend and try to plug directly into wall. If there is anything else someone can think of, I'm open to suggestions.

I mean the Ram sticks and it is very common for one of them to go bad. I don't think plugging the PC right into the wall will do anything, it just doesn't make any sense unless you have a surge protector with a circuit breaker and you are drawing enough power to trip the breaker, but that's very unlikely unless you have a lot of other things plugged into it.

Okay, whats the proper method to troubleshoot the RAM issue? Try to run each stick individually and see if the restarts are still concurring? I got the RAM from Microcenter, so if something is wrong I can stop by this weekend and get a different set of RAM.

As far as the power supply, I have the computer and my printer and speakers plugged into it. But with my previous desktop, I never had isues with it. It was just a thought, but like you said, I don't think thats really the issue.

Thanks for the help

Yeah just run each sick by itself and which ever one doesn't make the computer restart is the good one, it's pretty basic, or you can try to run a memory test but that doesn't always detect the problem.

Memtest 84. Run it completely with both sticks installed. It could take 8-12 hours to complete. Do it while you sleep. If you wake up before the test is done, hit snooze on your alarm clock ;)

I would try chkdsk as well, schedule a scan then reboot, I've had a similar problem only its a windows file that keeps going bad, repair/reinstall masks it for a while then it comes back, the hd is junk. Do you get any other problems like hanging when transfering files?
