Help with strange problem

post #1 of 9
Thread Starter 
Hello everyone. This is my first post on overclock.net, though I have lurked for a bit of time. I have a problem, and decided to come to this site for help because you guys seem to be hardware geniuses.
Anyway, my problem. Periodically I get strange freezing or choppyness when using my computer. Allow me to clarify. At random times (happens when I'm gaming, browsing internet, or doing anything) the mouse cursor will completely lock up. Sometimes, I can use the keyboard, but sometimes the display locks up as well. During this time, sound will continue to play. Also, every so often when this happens, my cursor will become distorted. It will stretch and become wide, look pixelated, and be colored randomly. In all cases, this lasts for a few seconds. I've tried resetting any and all overclocking I've done on the CPU and graphics card, and still get the same issue. I've tried completely purging my computer of video card drivers and reinstalling, which seemed to temporarily fix my issue.
My specs:
CPU: AMD Phenom II 905e
RAM: 4GB
Graphics card: MSI Cyclone GTX 460 768mb
Motherboard: MSI 770-G45
480W PSU

Thanks in advance!

Troubleshoot step by step-
start by deep virus scanning/cleaning
then if no luck, run a s.m.a.r.t test on your hardrive(s).
if nothing still, i'd definitely check your cables and see if your gpu is connected properly.

This is the deal from NCIX, right?
The 480W PSU you are using may not be enough to run that and a GTX 460 768MB; I'm assuming it is from Logitech, correct? If so it is in reality only a 330W (480W peak) and probably even less. Though I doubt this is causing the freezing, I recommend an immediate replacement.
Is the memory set correctly? What kit are you using?

The motherboard and CPU are a deal from NCIX, but the power supply is a separate one that is actually 480W. I checked to make sure that it had enough power to run all my components, and it did, so I doubt it's that. Not to mention that my problems occur during low-load as well, ruling out the power supply.

Also, I've never heard of having to set my memory. I'm using this memory kit: http://ncix.com/products/?sku=42745&vpn=F3-12800CL9D-4GBRL&manufacture=G%2ESkill&promoid=1275
It would be appreciated if you could point me to a guide that would instruct me on setting my memory.

I did virus scans, a S.M.A.R.T. test, and checked as well as cleaned all my connections, and the problem still persisted. I have also tried completely clearing and reinstalling my drivers, as well as reinstalling the OS. None of those helped.

I have a couple of strange symptoms to add to this problem. The first one is that the problem only persists in Nvidia cards (I tested a different one), and not ATI cards. Additionally, I can reproduce the problem to a certain extent by causing my cursor to rapidly change, such as by quickly moving it across the edge of a window. When this happens, the cursor artifacts very briefly similar to what I occasionally see during freezing. This doesn't happen on other computers.

And the second problem is that after the cursor freezes and unfreezes, for a short time the system performance gets degraded in some ways. First of all, the cursor freezes will happen a lot more frequently for a period of about 10 minutes. Also, during this time, web pages in Google Chrome take a lot more time to load, for no apparent reason, and will sometimes load incompletely or indefinitely. Another evident problem is that my iPod Touch will not immediately mount or charge when I connect it to the computer, but a significant time later. After a random amount of time, as I said, about 10 minutes, all the problems will stop.

The days of generic memory being the huge majority are over. As a result a lot of the time you need to set the memory multiplier to x8 in the BIOS and timings manually to 9-9-9-24 to get the performance you paid for. Refer to your motherboard manual and some guides here on OCN for more info.

What exact power supply do you have?

Aside from that this may actually be a driver problem. If not necessary an nVidia video card, it may be something else in your system; I remember I had a wi-fi card that froze a system of mine no matter what. I blamed the memory at first, but took out the wi-fi card and the problem disappeared.

So you're saying that the problem persists through different OS installs, and that you have tried more than one Nvidia graphics card?

If these are both true, then they both seem to point to driver issues.

If the problem persisted through OS installs, but you had only ever used one graphics card for testing, then I would feel semi-confident that the problem could lie in the graphics card itself. If what you say is true though (i'm not doubting you btw), then this pretty much eliminates this as a possibility.

If the problem was gone after the OS install and fresh drivers, then it would likely have been some sort of driver conflict.

Its always a good idea to actually set the memory to the recommended settings, and if you're really worried that it could be the memory, then I would run Memtest86 through a few times to ensure that the ram is stable.

Here are a few other questions for you.

Have you tried running a linux live CD to see if the problem is still there in a different operating system?

What other graphics cards did you try?

Check in the event viewer, do you see any record of these problems? For instance, if it starts acting crazy, right after that go look in the event viewer at everything recent and see if there are any errors in there.

Also, does the problem appear at random times, or in certain instances? If the problem only appears at certain times that could really help us narrow down what the problem could be. I know that you mentioned that you can kind of reproduce it, but you don't mention if that is what you are doing when it starts happening.

I think those are my only questions for now, but try configuring the ram for now and see if that works. Its too bad that you don't have integrated graphics... it makes testing these things so much easier rolleyes.gif.

Oh, and welcome to OCN, this place is great.

Good luck

My power supply is a Rosewill one, I don't know the exact model. Yes, I know they're crappy, but I don't have the money to replace it yet and will ASAP.

By the way, I forgot to tell you guys that I'm using Windows 7.

Setting my memory timings in the BIOS didn't solve the issue.

On other OSes, the issue doesn't seem to happen. I tried both Linux and osx86.

The other Nvidia card I tried is an 8500 GT. The ATI card is an HD 4850.

I've already tried looking in the event logs after the freezing happens, and didn't notice anything out of the ordinary. Any suggestions as to what to look for and in which log, so that I can know what I'm looking for next time?

No, the cursor movement causing artifacts doesn't cause the freezing. It was just another problem that I noticed and assume is related to the freezing issue, because the artifacting looks similar to what I sometimes notice when the freezing happens. I have noticed, however, that the freezing ONLY begins when I move the cursor. Otherwise, the times it begins are totally random.

In case it helps you guys diagnose my problem, I attached a picture that I took of the cursor when it froze and began to artifact.

Thanks!

So I take it that you're using windows 7 64bit right now?

And when you said that you tried using osx86... does that mean win7 32bit, XP or something else?

If the issue is not there in other installs on the same hardware, then it is almost certainly a driver issue or conflict. You could try going back to an older version of the driver and see if that fixes the issue.

Also, can you recall when this issue started? Meaning, is there anything that you changed that made this happen, or perhaps you noticed it happening after a certain event or something like that?

Good luck

Yes, I'm using Win7 64 bit. By osx86 I meant Mac OS X.

I tried reverting to the earliest driver that supports the GTX 460 and the issue remains.

I didn't notice the problem until a week or two after I bought it, though it was probably present before that without me noticing. The freezing seems to come and go every few days. Sometimes there will be a streak of a few days where it freezes all the time, and sometimes it can go for about a week without freezing.

Also, I should mention that when the drivers are uninstalled, the problem doesn't happen (neither the freezing, nor the reproducible artifacts).
