Hello guys,

I've been reading these forums for a few years now and have mostly been able to find solutions to my problems for quite some time (So thanks for that) however i'm currently stumped with this latest one.

This will be a fairly long post so again, thanks for taking the time to read it.

Recently built a new computer with the following components:
Processor: Intel(R) Core(TM) i5-4690 CPU @ 3.50GHz (4 CPUs), ~3.5GHz
Memory: Corsair 8192MB RAM
Motherboard: Gigabyte H97-HD3
GPU: Palit NVIDIA GeForce GTX 970 4GB
PSU: Corsair VS Series VS650
Single HDD: 1TB WD-Black

The problem is that whenever i play a more graphically intensive game (or more demanding), i get horizontal lines moving across my screen, then after a few minutes (depending on the game) my computer restarts, often to:
- no video input, no post message
- at times a post code that i can't seem to be able to find anywhere online: 2 Long beeps, 3 short
beeps
- 1 short beep, 1 long beep, where the computer actually boots up, but the entire system seem to be moving sluggish, video/audio playback is glitchy, etc.

I can reproduce this issue with pretty much any game, although it does seem to be alleviated for some games when i turn on VSYNC (limiting frame rate to 60)
A few examples:
Tomb Raider - Max details, 1080p reboots after about 20 minutes
Dying Light - Max details, reboots after about 5 minutes
Batman: Arkham Origins - Max details, reboots after about 30-40 minutes
Sleeping Dogs - Max details, reboots after about 10 minutes


Here are my idle temps & voltages in CPUID hwmonitor:

Here are my temps & voltages in the monitor while playing Dying Light:

I have already tried getting a better cooler for the CPU (Deepcool GAMMAXX 300), installed and everything, didn't notice much of a drop in CPU temperature really.

So i'm not really sure if it's overheating, faulty GPU, faulty PSU, or faulty anything else really?..

Any input is appreciated!


Update: Here's what shows up in the Event Viewer when one of these restarts occur.

Thanks for the reply, Bossyfins!

I've just tried out all 3 options (Small, Large & Blend) in prime95, and now i've left the first one run. The temps currently don't exceed 72C with any of the 3 options in there, plus i'm not seeing those horizontal lines that are usually shown before a reboot.

Here's a screengrab of all 3 programs if it helps:

Thanks!
I'll leave it on for the full hour and see if the temperature increases any further.

Update:
After the full hour, highest temp reached was 74C on Core#0 & the package.

GPU temp hasn't budged.

I will attempt to plug in my video card into another similar computer tomorrow, i guess. I've also got a couple more PSUs around here but they're around 550w so i'm not sure they'll be strong enough to power all the components.

One quick question though, is there any way for me to diagnose the PSU, or shall i just let the guys at the warranty handle it?

Thanks for the reply!

Great success!! I've managed to reproduce the restarting issue (along with the horizontal lines) by running the Power Supply test provided on the application.

I've just ran it again and cancelled it before restarting, and it outputted a bunch of PNGs that i can't really understand. Can you please have a look JED? I'm afraid the voltage stuff is going a bit over my head..

Hoping this hosting site is appropriate, i just used the first one i could recognize on google.

I cant open those. Go here (http://en.m.wikipedia.org/wiki/ATX) and scroll down to the table with tolerances. Open the file occt dumped one by one til u find one with the volts (3.3, 5, 12) and compare to the wiki. If theyre outside those then your psu is probably jacked (tho it could be mobo).

I believe the standard tolerance is around +- 5% for ATX specifications(for 12, 5, 3.3V). Anywhere outside this range can cause problems/possible damage. You would want to check your voltages idle and under load. Also be aware that software readings aren't completely accurate which is why people will recommend using a digital multimeter.

Alright i've looked at the voltages in both idle and load and they seem to be under what they should be. The voltages remain constant irrelevant of whether the pc is under load or not.

http://i61.tinypic.com/11sl378.png

+3.3V is sitting at 1.88V-1.98V
+5V is sitting at 3.40V-3.43V

Does this mean that the PSU is shafted?

Thanks again, i think we're getting somewhere..

Hey guys,

Just for the latest:

I've went out and purchased a new 800W powersource, installed it and had initially noticed the same lines and the same voltage HOWEVER the computer does not restart under the same circumstances (More testing on my part needed).

I then thought to change the display cable (since i was using a VGA cable with a DVI adaptor) to a DVI to DVI cable and lo-and-behold the lines are also gone.



I still can't figure out why the voltage is lower, but the computer seems to be working fine now so i'm not sure i should pursue this further.

Thank you for all the help!
Sam
