Wouldn't something that small have trouble handling the load at all?

If it doesn't freeze, sometimes the screen goes on/off. (Windows displays display driver has stopped and restarted) which I guess is due to the Video Card.
I tried several different driver versions.
Same issue.
What I did was set the time display driver would restart from 2 seconds to 1 second. (I added an entry to the registry for TdrDelay and set it to 1.)
This did seem to reduce the amount of hard freezes my computer has gotten from playing games and replaced it with simply the screen going off/on (driver restarting I assume but I never get to see see if there is a message in time). Though even with a 1 second delay, my computer still freezes every other day or so of playing.
Any ideas?
I dusted computer. GPU reaches a max of 85C under load (CPU is relatively cool too).
Due to the display driver restarting issue, it likely a problem with the video card?
I might just try replacing it again but I want to know for sure.
I've had "Display driver has stopped and restarted" even on old games but those happen like once every three months (it's really rare for old games). Also I have never had the computer freeze on me for older games (just display driver has stopped and restarted but never a freeze).
For more modern games, it happens every two-three days (freezes). Also sometimes it happens within 30 minutes of of starting up and playing the game and other times it takes 8 hours of playing. On occasion, sometimes I won't get freezes for several days too (but on average it happens once every two to three days or so).
Also the computer never freezes unless I am playing a game (and only a modern graphical intensive game). So from all this, does it seem the problem is with the video card or could it be due to something else?
What are your specs and driver version?

The key words are "Active PFC" power supply, as I understand it. So yes, you have a power supply that would need the "Smart" line.
Of course, looking at your linked UPS, I see under the Product Overview:
"Pure sine wave output on battery - Simulates utility power to provide the highest degree of compatibility for active PFC (power factor corrected) servers and sensitive electronics."
So that power supply is good from that standpoint, no worries.
The sticker shock though... $462 at Amazon. Wowzers. I have a Cyberpower UPS (at lower rating, because I don't have as heavy a power draw with no overclock, an 4670k, and only a single R9 280x TOP) and it works pretty decently. Of course, in the same range, the price is comparable - they have a 900w rated model at $200 on Amazon. Not sure if the 1000w is a dealbreaker or not - once you get up that far you start looking at more expensive models aimed at commercial/industrial use no matter who is making it.

A few stock bios 780's, a 3770k @~1.3vcore, even with all the bells and whistles at simultaneous 100% load on both CPU's and the CPU's, with a 90% efficient PSU i can't see it drawing 900 from the "wall" (ups)

Your system disk may be capable of scoring higher than 5.9. However, the test to determine this requires 1GB of contiguous free space. Try deleting unused files, then running the Disk Defragmenter before re-running the assessment.
Windows experience index rating my SSD as 5.9 because of this instead of the max rating - it bothers me a lot more than it should. I have 30GB of free space, but apparently not in a single block. I defragmented for a while before (even though i know you're not supposed to..) and it didn't "fix" it. This bothers me way more than it probably should, any ideas?

I'm assuming the hardware most likely to have the problem is the HDD, followed by the powersupply and the motherboard.
Is that assumption correct? What did you do with that HDD shut down setting? Here's a screenshot that shows how it should look: http://superuser.com/questions/146696/disable-turn-off-hard-disk-after-in-windows-7
Yes I did exactly as the picture shows.
The emergency shut down stopped after one time but the sound is still there.
It still freezes during the duration of the restart sound.
Sorry for late reply, was busy with work for the week.
EDIT: it started a day or two after I reinstalled Windows 7 so is that a possible problem? (believe I stated it before but just a reminder)

There is interesting information in that thread. The reason manufacturers recommend it is because APFC supplies are apparently more sensitive to the shift from line sine wave power to square sine wave power and back, and depending on the quality of the line power, UPS, etc, it's possible that you could damage the PSU. (I've also read where it makes the battery backup fail - not that it doesn't turn on, but that the switchover kicks the PSU in the jimmies and it shuts off anyways. It may or may not be that common, but does turn up frequently in UPS reviews.)
It's probably a move by APFC PSU manufacturers to cover themselves - even if it might work, they don't recommend it because they don't test for failure under those conditions as rigorously. I'd have to go read a lot more about the power factor correction to make a better guess.
|
APFC is done to achieve a high power factor, which is the input current to the device more or less following the shape of the input voltage (perfectly in sync is power factor of 1, the max). Current draw needs to be higher when the voltage is higher and lower when the voltage is lower.
For active power factor correction in a computer power supply, there's a controller responsible for a part of the circuit past the bridge rectifier that's pretty much a boost converter (output voltage is higher than input voltage). The key thing is that the controller regulates when the MOSFET switchers turn on and off, allowing current to flow when on and not when off. The controller switches those MOSFETs in such a way that the power supply draws current from the source in a manner that matches the input voltage. So the controller needs to measure the input voltage and so on.
If the input voltage jumps abruptly, this could do weird things to the circuit's operation as sudden jumps in voltage need to be accounted for. A non-sine input makes the problem tougher and less predictable, anyhow.

Hi all,
I've done a search but haven't been able to find that answer -
Can anyone recommend a decent free .pdf editing programme?
Thanks!

Having some issues with my tablet. It's a Samsung Tab 10.1. Always worked fine except there is a crack across the screen but it the screen still functions.
A couple days ago I plugged it into my charger and left it for a couple hours. When I came back it had not charged at all. Now if I plug it in nothing happens. If I connect it to my pc through usb it connects. The usb connect sound will play and then followed by the usb disconnected sound.
The only thing I can imagine is that I bought the tablet in the US and now I'm in Sweden, but it worked fine the first couple times that I charged it.
Any help is appreciated.

Is it the same usb charger cable you are using? If not try a different one - if it works that the cable is kaput, if it doesn't it may be an issue with the tablet. Possibly you pulled it out by the cable (rather than by holding the connector) and broke it when it worked last and now it doesn't.
I assume you dropped it to get the crack - is it still in warranty?

Just a quick thought, the back of the tablet says: Rated 5V;2A. the charger im using only says 5V;0.7A. Is the charger simply to weak?

Driver version: 327.23
Tried 320.49 and also the latest and still same results.
Also it can crash multiple times in a row.
Sometimes freeze 30 mins ago. Then restart then play again. Then freezes within 10 mins  .
On average about once every two days though (computer freezes while playing game, sound still plays and sometimes loops).

Charging behavior can be strange straight from the computer and off of an underpowered charger. I think that's probably it.
What might be different from the previous times you charged it is the current battery level, especially if it's lower. At a lower percentage of full charge, the battery voltage drops, and charging is usually faster and draws more current (lowering the voltage from the charger by more by loading it more, generally).
5V 2A chargers shouldn't be that uncommon and expensive. It's at least worth a shot.

We're on 340 now, 337.5 coming up on 4 months old, so 320 and 327 are probably pretty ancient by now. 337.50+ are pretty important, you should install newest beta or the newest non-beta if you don't want a beta driver (they are mostly fine!) for general use
Aside from that, you could set to use pci-e 2.0 instead of 3.0 in the bios. I don't know if that would do anything.
What's the PSU model exactly?
85c is not a problematic temperature AFAIK, but it's surprising to see it on a 650ti. There must be some bad airflow/cooling there for that to happen

I have tried using the latest version (and with a clean install too) and the problem still happens. I switched back just because I haven't had any problems with the current driver version I have, while I have read some reports of people having problems with the latest drivers on the guru3D forums (though to be fair, most of them seem isolated).
PSU is Corsair HX750 (Modular) 80 PLUS GOLD.
Randomly (sometimes within 10 mins or after 8-10 hours of playing or sometimes it'd take several days before it happens), the computer freezes and the sound loops.
And it only happens during games. Due to that, is it likely the video card that is the problem?
I'm thinking due to the similar problem of "Display driver has stopped responding and has recovered" (which also happened frequently with the game I am playing), it may be the video card (of course both cases could be unrelated).
My computer never freezes when I'm playing an old game or something that isn't graphically intensive.
Since it crashes only during games, is the likely cause of the problem the video card?
I just want to know if I should just try replacing the video card. Outside of that, my computer seems relatively stable (and again, it can play the majority of old games, like 5+ year old games fine without any freezes or anything going on). And I have dusted my computer a week ago too.

Dunno if it is the right thread: Wanted to watch the artosis stream, couldnt do so via firefox so i tried google chrome.It worked out ok but i realzed my fans were going really heavy 5min in, so i checked my graphics card load and it turned out it was going at 70% in contrast to the usual 5%. Did anyone notice the same?
