More Problems...

[hackman2007]

Well, I thought everything was fine, but apparently things are definitely not fine .

Everyday, multiple times per day my computer makes a sound similar to a computer that is shutting down but the computer does not shut down. During this last week, my computer has occasionally spontaneously went into sleep mode with no apparent reason.

I looked in Event Viewer and the program responsible was "Kernel - Power".

Anyone know what is going on?

check the system power settings (on the Screen Saver Tab) and make sure that the "turn of power to..." things are set to Never....

if it was any other person, i would say malware. do you have a multimeter handy? might want to get some voltage readings from your power supply

Event 41? I think it's trying to go to sleep, and instantly waking up.

[hackman2007]

Well, since this thread is at the top of the folder, I figure I might as well post in this one.

I'm still having problems, not exactly sleep problems anymore, but now my graphics card has once again started glitching in games .

I bought a multimeter today and tested the +12v rail on the power supply and it came out with 12.34. Seems normal to me. However, when I shut down the computer that number goes WAY up to 27. Is this normal?

This is the first time I've used a multimeter by the way. If there are any other things I should test, let me know.

Some time back I did this little DMM blurb for the forum, it may help a little.

Next, on shutdown I doubt you are seeing 27 Volts. Depending on the meter's autoranging what you may be seeing is something like 27 milli-volts. Meters can be funny as to how they display. The 27 milli-volts would be logical as it is just some noise the meter is seeing. Maybe there is a small mV in the display when you see that?

When the system and PSU shuts down the only active voltage you should be seeing is the 5 Volt SB (Stand By) rail.

Okay, that being said, I understand the working of these devices. So 12.34-12.35 is acceptable for 12v correct?

What component would you suspect next to test? I do have a movie of the sticking/freezing, but it is quite large (from FRAPS and is like 100MB). If you want to see it, let me know and I can get it to you. The movie itself is only like 10-15 seconds.

[Boy'nBlack]

Whoe, big movie! You can email it to me and I can try to compress it or something more friendly. I'd like to see it, and it may be useful to others as describing glitches can be quite hard to get accurate.

ATX allows for 5% (roughly) on each rail to be maintained as "stable". However, power supplies are so variable on how they actually spread the load to leads that the actual rail measurement in the PSU and individual leads can be very different. Note that most of these power supplies are parallel circuits, so Voltage will be common every where you poke; yet Amperage (the part that does the work and matters) won't be...and is indicitive of the load applied (variable while at work).

Where did you measure this from? I've got logs and logs of where to pull readings from for just about any video card so you're not just looking at leads alone...more telling readings if you ask me. I just prefer reading from the load in real time, just don't be loaded up on coffee when you do; believe me, my hands go nutso. Anyway, if from a blank lead to measure voltage, you still see the common parallel reading you should. It's not an indicator of what's happening. How about plugging the PCIe cord into the card and reading off the back of the connector while loaded? Those turned down pins going to the board are pretty easy to hit and will be on an active part...real time. And if you have those little grabby fingers for the leads, it'll be easier to set up and then boot up so you don't have to hold them.

The voltage thing when shutting down may be as simple as where you put the black lead. DMM's measure the difference of the two leads.If you put the red on 12V and black on 5V, the DMM will lead you to think the point you're measuring is 7V. I have to agree here with Ron though, as it's easy to mistake the autorange reading by overlooking the scale it's shifted to. I do it quite often and have to return for the measurement many times...common.

We can get that video up, but discribe your view of your glitch. Is it skipping, or graphical conflict? I'm sure the pretty mandatory "what's your temp" reply is coming up soon, so might as well put that at bay up front too. Power Supplies and temps seem to be the first questions, even if not replied to once given...eh?

BTW, we must be slipping. Two Free Clinic mods asking for help in the same week...in a different forum? I had graphical corruption this week too. The planets must not be aligned.

[hackman2007]

Probably a full moon.

Anyways, my temps look fine actually, around 40-50C for the GPU under load (measured with GPU-Z) and about 60C for the CPU (measure with Core Temp) under load.

The glitching is more like a skipping type thing, like it wants to render, but doesn't and then over-compensates. I'm really not sure how to describe it though.

I tested one of the molex connectors, in particular one that actually plugged into a hard drive. I didn't load the computer though, I wasn't really sure how to get the read anyways.

So do you want me to measure the DC voltage of the graphics card under load? Getting that video uploaded to Rapidshare so I don't to attach the video to your e-mail. Sorry it is so big, I tried to convert to something else, but kept getting errors (I suck at converting lol).

[Boy'nBlack]

It WAS a full moon. Figures.

Ok, shot in the dark, but what I think you describe is how I feel while gaming at work. Stall and then a catch up? If so...

I went from 1G ram to my own 2G ram and it's less common. Still does it in RTS games mainly. I'd blame graphics, but that's not a graphical thing...that's just the symptom we see. I look at the perfmon, and there's disk activity at the same time this occurs. Kind of hand in hand with memory capacity as far as resources go. But something, and I haven't figured out what myself, is taking presidence.

Svchost jumping up? I'm now focused on resouces due only to the way I think we're relating here. I'm not sure of a good way to log this though so you can check it outside of a game. Just feels like some program is loading to check updates, NETBIOS type cycle (network, not my thing) checking connection, or some other type of non-essential app popping it's head up. I love Irony though, and still have that sleep thing in the back of my mind.

I don't think it's a video card issue at all. Not ruling it out, but that's just not typical to skip or stall like that with video alone. Along with that, not a power supply issue right up front. And that's if it's the "stall, catch up" that I'm thinking of sharing here.

If it's a spacial thing, like a FSP mulitplayer jumping from A to B in a split second...might be a different story. I'd still prod you to figure a smart way to log resources and see if any jump up at these times, or even watch the HDD light on the case at these moments. Could be something just taking the drive for a moment. I've fixed that by moving a Creative card one slot upward.

At least send one of us your sig though brosuf. Can't make it out. Hit's good with that too. (I scooted forward, no card listed...this is the 1950 giving you grief?)
