Computer reboots under load

[David Barishev]

Hello all !

Around a year and a half ago, i upgraded my system from gtx 550 ti , to 970 g1 , and added Samsung 850 evo.

Everything was fine for a year, except couple of crashes hear and there, and sometimes didn't boot and made 3 short beeps, i mostly solved this by removing one ram stick and reinserting.

 

One day when i played my computer crashed, no blue screen, I tried to boot him up, and got short quick beeps when trying to boot. 
I was like , OK this has happened before so I got one ram stick out, and now the computer booted, was stuck on bios , and beeping every 30 seconds. 
I tried to unplug Hard drive , optical drive reader , every external phariperal and still same error- stuck on bios with long beeps every 30 seconds. 
I tried to boot without the GPU , which the computer did , and I was presented with this screen( I was using the onboard graphics),

.
I waited till it finished, and the computer booted up normally.
When I tried to insert the graphics card the computer doesn't want to bot and I'm getting 1 long beep , and 3 short ones. 
 

I sent the card to RMA (stupidly i know), and they returned it to me as the gpu was fine.My friend then tested the card on his system and it worked fine.

 

When i got the card, i inserted it into the pc, booted fine , had a very long bios screen 1-2 minutes, then windows loaded fine.I Fixed this problem by updating my bios version (F5 -> F12),

but now when i try to play a game, my computer just reboot after 20 min or so (depends on the game).

When im not doing anything that requires high gpu usage the computer is stable.

 

I wanted to test my machine to eliminate other problems, so i used a stress test that consisted of Furmark, and prime95, while recording sensors with hwinfo.

My computer rebooted after around 9 minutes.

 

I also did only prime95 for 2 hours, and my computer was fine, cpu peaked at 75c, but average was 65 c, so temperatures are not a problem.

 

Even in my games, and in the benchmark my gpu would work fine, and i got good frame rate.

I attached the stress test log below, and here are my full computer specs : http://speccy.piriform.com/results/d027LREWndsbtpYgHyEv7iT

I'm using Antec 500w 80+ bronze, dont know the exacts model, but here is an image with some data (This might be very useful - it states all the power info):

 

To summarize:

• Computer crashing during gpu load(Games , benchmarks )
• Cpu temperatures are fine(Gpu under full load while i was running the prime95 and furmark test was @ 80)
• Computer stable when not doing anything gpu related
• Gpu is 100% working 
   

 

I speculate the cause of the problem im my psu - its not giving enough power, but i want to be sure, and if so, what psu should i buy for my system ?

 

 

 

Thanks in advanced.

Yes, I'm pretty sure it's your PSU. To recommend what PSU, what is your budget and what is your processor 

[Anghammarad]

For example a Cooler Master V550. Or something similar from Seasonic.

 

How old is your PSU?

 

 

[David Barishev]

I posted full specs list above, but anyway processor is Intel Core i5 3450.

Budget is around 100$ , psu is 4 years old at least.

[budgidiere]

what's your budget?

@budgidiere

Usually a 500 watts PSU should be quite good for your system. But like said in several other posts, PSUs age with time and can't deliver constant power on high usage. 

 

My old Cooler Master 520 started with that after around 7 years of use. But you never know when that will start.

[budgidiere]

i don't think 100 is quite enough if you want a long lasting power supply form a reputable Brand. maybe 115-150

[David Barishev]

Would be great if you guys can pick from here, http://en.ksp.co.il/?select=.1108..140.&list=1&sort=2&glist=0&uin=0&txt_search=&buy=&minprice=0&maxprice=0&intersect=&rintersect=&store_real=

 

My budget is quite flexible , i will be able to invest in a long lasting one.

[budgidiere]

Acutely i found this PSU:  http://www.thermaltake.com/Power_Supply/Smart_Series_/Smart/C_00003005/Smart_Pro_RGB_750W_Bronze/design.htm

 

[budgidiere]

i would look into the PSU Tier List  chose one that is near the top (and the right wattage) from a brand you like.

[David Barishev]

What wattage should i pick to be safe ? 550 ?

[budgidiere]

if you want it to last for upgrades, and you want the most power efficiency i would get around 600-750.

[Anghammarad]

I would stick with 550. Currently the power usage of components go down. A 970 uses quite more power than any 10xx card. And right now the Intel CPUs for example gain only a little speed but power usage goes down.

[budgidiere]

@Anghammarad Fair Point

 

[David Barishev]

What do you guys think about SeaSonic 550W 80+ Gold G-550? Its tier 2 , and at around 121 bucks.

Looks Good
