Just built my first computer (hardware listed at the end of the post). Assembly was fine, but now when I try to use an operating system, the computer will lock up (or freeze, or whatever) seemingly randomly. This has happened when installing Ubuntu 10.10, running it from a flash drive, installing Windows Vista Ultimate. One of my gut reactions was a hard drive issue, so I took the hard drive from my old computer and popped it in, and it locked up on me using Windows 7, on a separate drive. I ran memtest overnight, no errors there, and the CPU temp seems to stay pretty decent (around 35 Celsius). my gut is now saying it may be the GPU. I hope its not, since I didn't have to buy that one (got it, unused, for free), and I REALLY don't want to have to spend more money right now.
Anyone have any ideas at all? This is really getting me discouraged.
UPDATE: Worked most of the day today when being idle. Locked up about 2 hours ago, and then again about 20 minutes ago. I'm completely lost at this point. If I have faulty hardware, I just want to know what it is so I can RMA it. AUGH.
Is it locking up running Ubuntu OR Windows OR it doesn't matter?
What does it do when it locks up? BSOD? Screen freezes? Do you have to cold restart? Does it just freeze no matter what it's doing, or is it only freezing when you do something? Any paticular something?
When it locks up, the screen just freezes. As far as I've noticed, it happens just at random times. Sometimes when installing/downloading something. Other times when its been just idle with few (if any) programs running.
It still might be RAM related even after passing MemTest.
Try giving the RAM a little extra voltage. Like 1.55v up from 1.5v or even 1.6v if 1.55 doesnt change things. .
Suggested mostly because it's an easy thing to change and test over time.
Tried upping the RAM voltage. Went from 1.50 to 1.54, then to 1.56, then to 1.60 and none of them worked. It ran well for a while at 1.54 but then locked up, and did it relatively quicker at 1.56 and 1.60.
Talked with a friend of mine. His best guess is that either the motherboard has some sort of issue, or the heatsink is bad. Recommending I use something other than a stock heatsink. He didn't get a chance to look at it, so that's just a guess, though.
A heat sink issue would show up in high CPU temps and a loud CPU fan.
I think if it was a MB issue it would not run at all.
A GPU problem would be most likely to show up during 3D gaming and less likely during 2D general purpose tasks.
Try booting into Windows Safe Mode (without networking). This will load minimal drivers for the OS and hopefully it will run stable enough to figure out if the problem is with the drivers.
The issue is mostly happening running Ubuntu (though I have a Windows Vista install disc that I've tried, but it keeps locking up upon installation). I have Windows 7 installed on a hard drive from my old computer, I could see if that all works. but is it going to be a driver issue, would it really happen in both Ubuntu and Windows?
Computer just ran very well for a while. Got through the first chunk of Portal with no issue and did some internet browsing. No problems at all. But I kept an eye on the temps, and the GPU, CPU, and MB all got to around 40 celsius and the thing locked up. Hit the reset button on the case, tried again and it locked up almost instantly after I logged into ubuntu (I opened firefox and BOOM!). Rebooted into BIOS mode and the temps are still around 40 for CPU and MB. Don't know how particularly safe or unsafe that is, though.
Had the same problem with my new Gigabyte G31M-ES2L, and I run Ubuntu 10.10. Frankly, I've been struggling with this issue for about a year. But today, while I was searching ( as usual ) for the solution on Google, and I found a thread that maybe useful and worth to try. It said to disable ' smart and quiet ' fan in BIOS. Its how it is in my BIOS setting, and I don't know about your BIOS. But whatever ' smart and quiet ' should be OK. And I've been running Ubuntu 10.10 for five hours without freezing. I really hope that it'll remain as it is. Thanks.
