My brand new computer that i built sometimes freezes at random with a crackling noise through the speakers and the lights on my mouse and keyboard go out. i'm a little worried about it. My system is Core I5 2500k overclocked to 4.3ghz, and it did all this before the OC though,ASUS P8P67 PRO motherboard, GTX 570, EVGA superclocked(bought it on sale), Western Digital Caviar Black 1.5tb, 8 gb RAM Patriot Sector 5, Kingwin Mach 1 1kw PSU. and my case has a dangling USB wire in the case, but i doubt it's making contact with the motherboard, because if it did, it wouldn't reboot, ever again.
I'm fairly certain it's because of your PSU. Kingwin isn't exactly known for their quality. You should've bought something like a 650 watt Corsair HX, instead. -I'm wrong-
[QUOTE=RixxzIV;31029739]I'm fairly certain it's because of your PSU. Kingwin isn't exactly known for their quality. You should've bought something like a 650 watt Corsair HX, instead.[/QUOTE] From first glance inside the PSU, it's a heavily built out PSU: [url]http://www.pcper.com/reviews/Cases-and-Cooling/Kingwin-Mach-1-ABT-1000MA1S-Power-Supply-Review/Under-Hood[/url] It has all of the required stages, plus some extra coils, this is no trash PSU. The load tests prove this: [url]http://www.pcper.com/reviews/Cases-and-Cooling/Kingwin-Mach-1-ABT-1000MA1S-Power-Supply-Review/Load-Regulation-Line-Regul[/url] The Kingwin he has is a fine PSU, as it should be, they cost in the range of $150.
Guess they've improved. OP, does the PC freeze for a couple of seconds, and then come back to life? Or does it freeze permanently, forcing you to reboot?
Forces a reboot, and i have to use the hard reset.
Why would you overclock an unstable system.. Reset everything to stock settings and run [url]www.memtest.org[/url] for 8 hours, or until memory errors show up, if any.
Actually, it happened less often with the overclock, strangely enough, it's at extreme random now. it could happen several times in a row, or i could go a week or longer without seeing anything wrong. strangely =, i was watching a video, it happened, then it unfroze, but the video turned green and it was all slow as shit and crackly with the sound, typical of a serious case of lag.
Sounds like something's wrong with the GPU. It wouldn't surprise me, as I've bought several factory overclocked EVGA Nvidia cards in the past and they would all eventually start screwing up due to being overclocked too far with usually inadequate cooling. You can try setting the core and memory clocks to what they should normally be (check other stock 570 cards for reference) with Rivatuner and see if that solves the problem.
I reset the clocks to normal and then i started getting extreme artifacts that would just annoy me so i set the clocks back to what EVGA set them to.
[QUOTE=zombini;31051228]I reset the clocks to normal and then i started getting extreme artifacts that would just annoy me so i set the clocks back to what EVGA set them to.[/QUOTE] Uh, EVGA clocks are higher than normal clocks. If you set them to default clocks and are getting artifacts, the card is bad. You need to RMA it.
Ok, i just had another incident, i was watching "Meet The Medic" and it happened, so i'm going to apply for an RMA so, i will be contacting EVGA. EDIT: also, i don't know much about the RMA procedure, i just read it on the EVGA site and it says that if i use something like anti-static foam or packing peanuts, they will reject it immediately and sent it back. EDIT2: fuck it, ill sell it as is on Ebay for $275. I'm not gonna fuck with it any more, ill just get a 6970.
Selling on ebay is a much bigger hassle than shipping it back to EVGA. Just put it in an anti-static bag (like the one motherboards come in) and in some small box and ship it back. And assuming you do manage to sell it on Ebay, you have to pay a variable listing fee, and a final value fee of 9%, which would be a $24.75 whammy. Shipping it back to EVGA costs less than half that in shipping only.
Well, i bought my graphics card in late april, do they still take it out of warranty? EDIT: to hell with RMA, since my card is out of warranty, im going on a sales site, Ebay would be faster, but craigslist would work, i think.
Video cards generally have 3-5 year warranties.
[QUOTE=bohb;31082859]Video cards generally have 3-5 year warranties.[/QUOTE] Box for mine said 30 days to register for a 2 year warranty, and i got it in late april. i'm fucked. ill just sell it and buy a 6970, or a 6990, and i've been wanting the latter, but it's rare now. both Tigerdirect AND Newegg are either sold out, ot stopped carrying them.
Send it to me and I'll try to fix it :downs:
My computer did a reset for an update. when it rebooted, after the windows 7 load screen, there was static in the middle of the screen for a second, then it froze, then the speaker on the motherboard let out a Beep that was continuous and didn't stop until i restarted the computer. It's scaring the hell out of me, i have a lot of money in this computer, and i don't want to have to build another using what's left of my bank account.
I still think it's the GPU. Though it wouldn't hurt to try some other tests. You can run a memtest for several hours: [url]www.memtest.org[/url] I'm fairly certain the PSU isn't bad, but if you have a spare that can run the GPU on it, go ahead and try it for grins.
Why haven't you removed this broken GPU yet? I'm guessing your motherboard doesn't have any built-in video otherwise you're being pretty stupid running the thing knowing the GPU is fucked. From what I can tell from the EVGA site the 30 days is "Optional Extended Warranty and Step-Up™". Try to register the thing even if you don't believe you can it's not like it will do anything bad, you only have something to gain from trying.
I'm preparing to run memtest. EDIT: Ran Memtest for 20 minutes, i come back to my computer, it's in windows 7 again. what the fuck happened. EDIT2: i've started the RMA process. I hope it goes through, i really do. My system freezing and the hard resets cannot be good for the rest of my computer.
Could be your power supply, try another power supply see if it fixes that.
I've taken out the 570, rooted through my box of old parts and found an old 8400 gs. not really usable for shit as far as games go, but at least i have a display system. i don't know what the onboard gpu for the mobo is, but ill find out and use it if i can.

Some hardware is known not to run memtest properly, but that's usually pretty rare. Did you actually watch memtest start testing memory, or did you just set it to boot and walk away?

[editline]14th July 2011[/editline] Ok, im going to run a couple videos for a bit, if it freezes, then something else is wrong, and if so, my computer is fucked. i'm out of money. EDIT: i'm going to run a long video over night, and i will be recording the sound of it with my phone, so, if i hear the crackling or a stop in the sound before the video ends, im calling it that my system is junk.
Well you probably don't trust someone over the internet with your computer, but if you ship it to me, I'll diagnose and repair it for free, if it doesn't require replacement parts. You just have to pay shipping back and forth.
Ok, i've done it, i've proven so far that it was my 570 causing the freezing. i ran a long youtube video over night to see if it freezes because it almost always crashes after 20 minuts of videos. no crash.
Good! If the RMA doesn't go through, you can buy a heat gun and try and reflow the GPU, Lol.
[QUOTE=bohb;31108661]Good! If the RMA doesn't go through, you can buy a heat gun and try and reflow the GPU, Lol.[/QUOTE] Reflowing doesn't work that often, i've tried it with my old 8600 gt from my last computer. it made it not even work at all, and i do in fact have a heatgun, and my old computer has a GTS 250 in it that replaced the 8600 gt.
Reflowing with a heat gun is an art that takes lots of practice and skill to get it done right. Throwing it in the oven is pretty much guaranteed to fry the card. Basically you need to take the heatsink and fan off, then clean the thermal compound off. Then you'll need to make some double or quadruple ply aluminum sheets and cover everything near the GPU (with an air gap underneath to avoid making an enclosed furnace.) Then you'll need to use a heat gun to heat the GPU surface directly for about 30-45 seconds. After you're done heating the GPU, you'll want to cool it fairly quickly (use a 80mm computer fan) BUT don't move the card around unless you want tons of melted together solder joints.
EVGA just got back to me with a reply about my question and so far, they think it's a failing card, but now i'm unsure, i checked my PSU and it's fine, but memtest freezes on me. so, bad ram and graphics card? Running an artifact test with OC scanner.
