Computer Randomly Restarts.

April 12, 2013 12:15:02 AM

I would be doing stuff... anything, browsing the web, playing games, etc., and my computer would just randomly turn off... make a *BEEP* and turn back on.

GPU = Radeon R7850 MSI Twin Frozr III
CPU = i5-2500K Sandy Bridge
Mobo = As

--- IT DID IT AS I WAS TYPING THIS RIGHT HERE ---

Mobo = Asrock Z68 Extreme3 Gen3
PSU = Corsair CX600
Case = CM HAF 912
RAM = G-Skills Ripjaws 8GB, 2x4, DDR3-1333
Stock Case Fans, Stock CPU Fan.

I'm not sure what the problem is, I tried defragmenting... I ran Auslogic Boostspeed. I cannot find a pattern either, it does it whenever it feels like it.

The GPU is not overheating, nothing is overheating, I have checked and made sure through the Catalyst Control Center.

Wires are tucked to the side using the little plastic tie thingies... No metals touching weird metals...

OTHER DETAILS
-Never did this at my first home, it was placed on the carpet on the second floor of the house
-Rarely did this at my second home, placed in a carpet over concrete floors
-ALWAYS does this at my current home, placed on a carpet floor, second floor of the house.

Please help, it's driving me nuts, coming to Tomshardware.com should have been my first step... but I ignored it as it wasn't as frequent.

Lots of dust on carpets, always have the PC on a board or raised above the floor. Check the PC for dust in the internal fans and motherboard and also the PSU. Turn off from mains power before blowing out the dust.

As you say, there was no issue when you had it on a concrete floor.

Overheating isn't a problem, I don't think it has ever overheated... Meaning the case has never been hot... GPU at 25 C, (Whenever I actually do check)
How do I check for a defective PSU?

Yes there may be dust on carpets, but I have cleared the insides from dust, it is relatively dust free.
There was no issue when I had it on concrete floor... but the concrete floor was under a carpet ._. so in all 3 scenarios, the rig was on carpet :o

It is best to put some floor tiles under the PC or a length of board to keep the pc off the carpet or floor.
The CM HAF 912 requires the PSU to be placed on the bottom of the case, you should have an internal fan near it to reduce the heat dissipation as it is really close to the video card. The fan on the PSU blows air into the video card and might be causing a heat problem, maybe. Just taking guesses right now as there doesn't seem anything else that might be causing the problem, you might have to get a bigger case. Perhaps you could take a snapshot of the inside of the cse so we can see whether there would be an issue with the video card fan ad the top fan of the PSU.

You don't need 25% free space. I currently have less than 4% and everything's working fine. BTW, I'm planning to buy a new 3 TB drive pretty soon :D  Do you have a reference on that?

As for PSU testing, easiest would be to just try a known, working PSU and see whether that fixes your problem. Ask a friend or take it to a computer store. If that's not possible, you can try the paper clip test with a multimeter (google). That's not conclusive however. Some computer hardware stores also offer PSU tester services.

I have 500GB Seagate baracuda, about 45% free space. I've done the paper clip test before... but how do i verify the fault without taking it to a store...? pretty lazy actually.

I'll try a tile under the tower... see what that does.
Through Bitdefender's quick scans, I have yet to run into viruses, altough Auslogics Boostspeed finds like 70+ daily... Something sound fishy here?

After a round of League of Legends, my GPU was at 31 C, is that a bad temp or is it fine?

EDIT: GPU Temp. check after another round of League of Legends: 35 C.
Bitdefender's full scan has detected 23 "threats" at 57% of the scan.

EDIT: Record breaking 8 hours so far.

It's been a while since last post but how are things now?

You can't manually delete most viruses, they replicate themselves when you do it.
Use Killbox.exe to kill it or install MSE (anit-virus) then scan for it to remove the infectins and clean infected files.

I think that LoL only works well with the 0000' nvidia video cards, like GT 8800 .. rather than the later types of the 000's like GT 650.
It worked fine for me with Windows 7 x32 using GT 8600 video card.

Recommended System Requirements
•3 GHz processor
•2 GB of RAM (Windows Vista and 7 users should use 4 GB of RAM or more.)
•12 GB available hard disk space
•GeForce 8800 or equivalent video card (Dedicated GPU with 512MB+ Video Memory(VRAM))
•Support for DirectX v9.0c or better.
•Windows XP with the latest service pack installed, Windows Vista with the latest service pack installed, or Windows 7
•The latest update to .NET Framework from Microsoft

Appreciate your help, honestly.
'
It wasn't a software issue, it was a hardware issue. The little rubber pads that keep the PSU off of the case was worn down. I replaced them with these suede pads... which shouldn't be a problem. I don't think they're conductive or anything. The pads are sticky on one side, so I attached the sticky part onto the case, and the PSU is just sitting on top. I cut the pads into little nail sized pieces so I don't think it would affect the air flow or anything like that.

It hasn't restarted since. In the end, it was metal on metal action going on. Thanks a lot for your help!

"The little rubber pads that keep the PSU off of the case was worn down" what little rubber pads and why is the PSU even touching the side of the case? Is the PSU even screwed into the case?

Metal on Metal action, isn't the PSU connecting with metal where it is screwed into place?
You might want to consider replacing that PSU if it is causing static electricity.

Little black, circular pads that came with the case. http://www.legitreviews.com/images/reviews/1406/cooler_... You can see the 4 little black dots on the bottom of the case. On the inside, they're little circular things that may be meant to hold the PSU off of the case? I'm not sure.
The PSU is touching the side of the case, I don't know why, I had no choice.
The PSU is definitely screwed in place.

Now that I think about it... it has been touching metal constantly... But the little pads seem to have helped.

Those pads are called "feet", they hold up the PC and stops it from wobbling. They don't do anything other than hold up the PC on a even level.

The PSU fan faces downwards to the floor or desk, there has bee some conjecture as to whether the space between is suffucient for airflow, manufacturers claim that it is enough, I wouldn't concur, it's not even one inch clearance!

30C to 40C temp for a GPU seems to me rather cool, I'd have expected it to be more like around 40C to 50C. The Video card might not be getting its fair share of juice, perhaps the PSU is suffocating? Try adding a block (of wood or a couple of books) at each end of the PC to raise it up so the clearance is more like 4 inches from where it sits.

I would say, overall, that the PSU was not delivering its requirement for the video card.

I know of the "feet" but there is a little outline of an imaginary square where the PSU should sit.

I only have 1 wooden block under my pc, I'll try more.
I was told that the PSU would be good enough to run everything o_o

I've got a Fatal1ty motherboard, it came with a water cooler (and 5 inch radiator). The double hose-pipe radiator wouldn't fit in the case and was affixed to the back of the skeleton PC case. The radiator and was leaking. A neighbour threw it out rig set pu, it looked good, though. I did do a bench test, and the temps were in the range of 50C. The radiator began to leak, I had to remove one pipe to divert the coolant, to stop the leaking. The temps actually dropped to around 35C. Not that that has anything to do with anything, I've just not seen any threads where a Fatal1ty motherboard has been used except this one, if in fact your motherboard is actually a Fatal1ty (Asrock).

I would assume the CX600 would have been more than suited, it just might be something else like some sort of option in the Control Center for the video card, perhaps. Do you use fan control?

I actually have no real clue, am just taking pot shots. :(

Yes I have checked out the fan control, I put it to 70% when I used to think it helped... It didn't...

The only other thing it might be is the Radeon R7850 MSI Twin Frozr III or the 1333mhz ram.

The Radeon R7850 MSI Twin Frozr III is the only model of the 7850 video card range that can actually be overclocked so perhaps you should try a squidgeon of OCing?

The QVL list refers to 4pcs of ram rather than any reference to 2 x 4gb of ram, it might be just saying that it can take 4 pcs but maybe it is really saying that it needs 4 x 4gb... OC is not listed as being available for the ram 1600mhz or lower...
http://www.asrock.com/mb/overview.asp?cat=Memory&Model=... Extreme3 Gen3

Considering all else, you may need to add 2 extra modules of ram.

Why now? Who knows?

If it's none of the above then it is whatever you have recently installed, updated, added, changed or re-configured.

It could also be a hard drive ready for the hdd retirement village especially if you have been gaming for long hours, done any video editing or movie making or compiling programme source code.

:(  It's really weird because when it dies on me, sometimes it doesn't have the power... or connection... or whatever to automatically turn back on. I have to fiddle with the PSU power cord or turn the power switch off and on.

Which part is the most likely to be the problem... if you could take an educated guess?

Any fiddlig with a power cord is actually creating a disjointing of the power, you need to RMA the PSU, I'd say, the fitting of the power cord plug to the PSU should be a firm and secure fit.

You nee to try a different power cord, one that isn''t a thin-looking cable but is more thick. I've found that the thicker power cords fit better in the back of the PSU and the thin cord fit better with the monitor.

Yopu are not supposed to turn off the power to the PC when not in use, you only turn off the power directly when you want to do something inside the PC case like reseating or changing something. The cmos battery relies on the trickle of power through the cord when the PC is shut down otherwise the cmos battery has to be activated to maintain the bios settings.

RMA - Return to Manufacturer Application
It's like a warranty of sorts whereby you can apply online (or by phone or mail) to return the product for replacement or refund

The connection is loose if the power cord is fitting snugly. You need a new or different PSU.

Why is it that you need to even touch the power cord?
Leave the power point turned on, just shut down the PC.
You only need to turn off the power point if you need to access the insides of the PC.

I don't NEED to touch the power cord, but when it does the shit it does... you become eager to try things.

Actually, you did mention it in the opening details, I just forgot it was there - "PSU = Corsair CX600", my bad!
Corsair PSU have a 5 year warranty so I'd send it back for a replacement.

Just unplug the plug the check the fitting of the plug in the back of the PSU, it should not be wobbly or loose fitting.
Check the silver connectors for any discolouration or if they seem to be bent.

Edit - the random restarts is caused by the loose fitting, the power cord may be knocked or being touched by something else.
The power cord should not be tight or taut between the PSU and the power board.

The loose fitting is doubtful, however, I'll organize the cords in the back for good measure. I'll keep you updated, and thanks again, very, very much.
