Has this happened to you ever?

[Anusha]

When you do something that stresses the PC (gaming, rendering, encoding etc.) and when the power goes off, even if you have a UPS, the PC might reset/turn off. Or the PC could reset/turn off when the power comes back on. :angry:

Has this happened to anyone? Have you found a solution for it?

[zerocool]

hmm i never had this kind of a problem with my ups yet...:rolleyes: :rolleyes: :rolleyes: :rolleyes:

This might be a problem in your ups i think...:rolleyes: :rolleyes: :rolleyes: :rolleyes: :confused:

[Anusha]

I replaced the UPS and it didn't go away.

oh i c....now there is a small test you can do....take your ups to one of your friends house and try cutting the main power and see if its happening there also...if yes then you know what to do....:yes: :yes: :yes: :yes:

What should I do if that happens there also? Or if it doesn't happen there?

I know few other people who have this problem.

[Novindu]

hmmm yeah i had dat prob lil bak...but recently i din have it ne:no:

Maybe because you have removed one of your RAMs?

[Novindu]

nooo dis happend ta me lil bak machooo even bfr dat ram thn....i thnk its bcoz da ups is trying ta protect it self from been damaged...or som high voltage comes tada cpu through da ups.........!!!

[zerocool]

What should I do if that happens there also? Or if it doesn't happen there?

I know few other people who have this problem.

im not an expert on these kind of things, this is just my personal exp. :D

as far as i know these kind of things will happen due to three reasons...
bad ups
bad power supply
bad motherboard battery

so if your friend has a good setup which doesn't have this problem then take your ups to that pace and check. so you know if there is a problem in your ups or not.

[Anusha]

Anyway, I had this problem with every UPS I tested on my PC : different brands and capacities. :rolleyes:

I also tested it with two different power supplies too. Same thing.

Now what?

[zerocool]

nooo dis happend ta me lil bak machooo even bfr dat ram thn....i thnk its bcoz da ups is trying ta protect it self from been damaged...or som high voltage comes tada cpu through da ups.........!!!

that is not an option for the ups...if there is a high voltage ups must normalize it and send it to the pc, that's what ups do right..:rolleyes:

oh this is strange...then there must be a problem in your mother board or something or some feature...:rolleyes: :rolleyes: :rolleyes: :rolleyes:

I'm so amazed that there aren't many people in this forum that have experienced this.

[Anusha]

Yes, a good UPS should regulate the power output from it.

[charmer]

Hey mate,

Did you check the fan and heat sink on the processor is fine you might need to give a service, if there's dust.

Next thing is the correct jumper/basic settngs on the mobo for processor (Read the Mobo Manual for more info)
Try Installing drivers for chipset too


I think somethings getting heats up and reset the computer or incorrect hardware configuration (possibly the mother board settings for processor)

good luck anusha mate

It has nothing to do with software or drivers. :no:
It's not a overheating problem. This is a new CPU/motherboard. Same happened with the old PC too.

[sridanu]

well all i can thik of is dat its either somthing wrong with ur UPS inbuilt stabilizer. U might want to check it out.

Also if the power consumption of ur UPS is too high, Then it cant support the power output and will turn off when the power goes off. This is typical if u have a 17" CRT monitor.

[Anusha]

A normal UPS is capable of handling a 17" monitor easily. Just that you shouldn't turn it on if it's already off, while the PC is running on power provided through the UPS' battery. Sure, it will lower the uptime of the PC because of the high power draw, but it should not restart the PC.

But the thing is, this happens with other UPS as well - not even the same brand. I have already changed this UPS telling them that there is such a problem.

My UPS is a PowerTree S600B btw.

[ifadh132]

i think its a power surge...

[ifadh132]

u will need a stabilizer....

[Anusha]

i think its a power surge...

It's not a power surge. This happens every time the power goes on and off - when I'm doing something heavy.

[HishamZz]

This prob is UPS based.. certain UPS produced are based for minimal power specs of a computer and once the computer is under heavy load more power is consumed and thus the UPS cant supply what is required and then the restart as ya say occurs..

My UPS supplies power to 2 computers and yes if the computer load is higher at times it switches off.I had mine replaced with another similiar one though and that gave no problems.. the problem is UPS based and not computer based..

go for a good brand with a good power supply rate... make sure your UPS supports more than what ya require for safety.. constant sudden power off/resets does not make anythin easier on the mobo..

[Anusha]

The UPS has an inbuilt stabilizer. It's not very strong, but OK.

It looks as if the problem is in the UPS. But when I plugged in another UPS from a different brand (this is a brand new UPS), the problem didn't go away.

[HishamZz]

As i mentioned buddy.. to cut down costs dese manufacturers base it on the minimal power spec.. and when ya have a powerful colour card combined with more hardware attached the need for alternative power supply via the UPS grows, and once the limit is reached the UPS resets.. I have experienced the problem.. the only efficient solution would be to have a more powerful UPS in the sense a UPS which supplies more power that what would be required for a single PC..

Else, disconnect the addional hardware such as printers, scanners which might be attached to the UPS and try it out.. but i doubt whether it would work..

[Novindu]

hey anusha....what HishamZz says may be correct...if u wanna test it u can do dis......while da pc is on switch off da pow to da ups...den da pc runs on ups ryt?? den switch off ur monitor for abt1 min and den switch it on!!! da samethn will happen....i thnk dats bcoz of dat what HishamZz is sayin;);)

[zerocool]

ya but inmy case once da whole ups got switched off and restarted.....

then it is problem in your ups..how long have you been using this ups.:confused: :confused:

[Anusha]

Oh ok. Seems like I'm the only one having this problem in this whole community.

I have solved this problem however. Just wanted to know what you thought about it and help others if they have this problem too.

It wasn't the UPS!!! It was the power supply.

Every Power Supply Unit has a thing called hold back time (the terminology may slightly differ however). This shows how long the power supply can hold PC working, even after the power fails. Obviously this is int milliseconds. This is what an UPS exploits when switching to the battery. The Power Supply Unit's hold back time should be longer than the UPS' switching time.

The hold back time is determined by the capacitors inside the Power Supply Unit. When a bigger load current is drawn from the capacitors, they discharge quickly, and the hold back time will dip. That's why it might reset the PC when doing a stressful task, than when lying idle.

The generic power supplies we get in Sri Lanka for around Rs.1,500 or even less are not good. Their hold back time maybe be enough when no so much power is drawn from the power supply, but once a high power is drawn, the hold back time will go down tremendously.

I don't think the UPS we get for around Rs.4,000 are bad. But a faster switching UPS would have been able to cancel the incapabilities of the power supply unit, but by how much?

I had to buy a good power supply to get rid of this ghastly problem. This is a server power supply (well, that's what they call it), and I had to spend Rs.5250 on it. It's still not the best by all means, and enthusiasts will call this a very low end power supply unit. But at least, I got my problem solved by buying this power supply.

[Anusha]

ya but inmy case once da whole ups got switched off and restarted.....

Once? lol

You should not turn on a CRT while running in battery mode!!!!:shocked: :shocked: :shocked:

It's not a problem with the UPS. CRT monitors draw a huge amount power when they are starting. After that, it will come down to around 70-100W.

[Novindu]

then it is problem in your ups..how long have you been using this ups.:confused: :confused:

You know, your UPS may also contribute to this, because of the age. But it's more the power supply than the UPS which is the culprit.

In your case, it could be that the UPS has deteriorated its battery pack. But if you get resets when power goes on or off, then it's related more to the power supply unit.

[HishamZz]

I doubt whether there any inefficiency in the powersupply dude.. i ve swapped ma ups wit a more powerful one and no probz.. though the part bout the ups exploting the switch time is good info, the problem underlying in most scenario is underpowered UPSs.. while ya prob would relate 2 da power supply maybe.. da rest o da guys undergo probz as a result o da number o devices they connect...

ma older UPS when on battery goes on a resetting frenzy just in case I off n on the monitor... it is more about the drawing of power than switching in ma case.. mind ya UPS r way more quicker than home based inverters in the norm.. so switching is extremely fast..

though i stil dont get ya prob bro.. ya mentioned that the computer went off under stress use whilst direct power supply or UPS?

This problem I'm talking about is only related to the switching system. There could be other problems with UPSes.

The PC was under a lot of stress while the power went off/back on. One occasion, I was playing Doom3, once I was encoding a DVD, once I was rendering a Maya animation. That last one is so bad!!! You know how long it takes to render a video a in Maya.

The thing is, the hold off time is related to the load of the system. (because higher the power drain from the capacitors -while the power is already out - lower the hold off time) Most high quality power supply manufacturers put it in their Power Supply Unit's specifications, and this is not the typical hold off time. They put the hold off time at max load. New UPS all have a faster switching time than that hold off time of those power supplies.

[fazaal24]

When you do something that stresses the PC (gaming, rendering, encoding etc.) and when the power goes off, even if you have a UPS, the PC might reset/turn off. Or the PC could reset/turn off when the power comes back on. :angry:

Has this happened to anyone? Have you found a solution for it?
Because it drags more power [more As] it resets.There is no way u can stop it.Or try buying a UPS with LCD,password protection,and other things for about 3 lakhs.This will stand by for about 15-20 hours:lol::lol::lol:

[eranda]

Ya i too fased that problem....itz a problem of ur UPs

[malkavi]

I faced to this prob also...
Its a problem with ups. And also some power sups has this problem. But you cant check this by turning off the main switch. this happened only when power cut occurs.

[zCexVe]

yeah,yeah coz of the too much load.Try to use a 1.2 KVA or higher one.Or just dont use a one like me :lol::lol:

[sridanu]

I disagree with ya.When rendering videos i used to bring in my neighbour frnds ups.with my earlier pc it resetted.But sometimes in my new one too it resets.My new one has a 500W PSU which can hold a Sine curve [approx 1/25 secs].but it still resets:confused: can u have me an answer?

I told ya ayya this isnt both of ours fault,but the connection speeds...:)

[Anusha]

APC UPS's doesn't look that great, at least on the specifications listing. 600VA can only supply a 390W power. PowerTree 600VA's can supply 480W power. And I couldn't find out the switching delay of them. Mine has a maximum of 0.2s (0.1s typcally)

However, I couldn't find much info about your Power Supply; mine neither. :(

I just told you how I got my problem fixed. Maybe that APC UPS doesn't have a low switching delay. Can't say for sure.
