Please check out this picture I took of my screen:

I keep getting these lockups on my laptop where the screen goes like this. All along the right side are these weird artifacts.

When I feel underneath the laptop, it doesn't feel so hot as if it were overheating. It's felt way hotter before.

A few minutes after another lockup, I check speedfan temps:
HD0: 43
ACPI: 58 (note: this one kinda broken; doesn't change with time)
Core 0: 33
Core 1: 33

I just got a lockup like this twice in the last half hour, both while trying to install XP in a VM. Definately not the most intense operation, (funny I was even watching performance in task manager in the pic!)

Specs are the durabook in sig.

What's wrong with this notebook? :mad: I even got lower temps recently after cleaning off the original thermal pad with ArctiClean and using some MX-2 on the cpu.

I haven't been able to reproduce this lockup until just now with it happening on the VM installation twice.


edit: Just thought I should run memtest. I'll post the results
 
I ran into some weird color changes/artifcating like this on a desktop I was troubleshooting.

It turned out it was the motherboard in my case, I was sure it was the video card but I put in a new one and got even weirder intermittent problems.

I'd look into your warranty/repair options... it's not easy being that it's a laptop.
 
got a couple memtest passes done with no errors

This is frustrating since I built this laptop to replace the last one I had that had a bad motherboard. Right now I just need something that works, but I'll have to see what kind of warranty I got seeing it's a barebones...

Anyone got ideas for tests I could run? Maybe 3dmark or something to stress the graphics chip? Anything else for chipset stress test?
 
Orthos blend test of CPU/RAM for as long as you can.

also leave memtest on for a long time.

try reformatting?

driver cleaners...

spyware scans/virus scans...

that's all i've got for the moment.
 
omg, i just tried the orthos blend test

it did the lockup after like 5 seconds!!

could it be bad cpu? bad motherboard? crap!!

trying again, after 25s it locked up with core temps going from initially 33ish to 50,51
 
More detail:

10 minutes of Small FFTs test went fine,
ACPI temp went up to 86
Core temps maxed at 69
holy shit, this thing is going to catch on fire in the summer

Ran Large, in-place FFTs for ~2min with no problems

Blend lasts about 20 sec before I lockup, temps don't get nearly as hot in that time

StressCPU with Gromacs core, for ~2min shows no problems


What does this point to? Memtest was fine for a few rounds over an hour-ish, and the other CPU tests are seemingly ok. Is the mobo/chipset just screwed up?


EDIT: well Blend is not failing with only 1 stick of RAM. I'll see if it can run for a long time now. Crucial said this stuff was tested for this notebook, but clearly its unstable with 2 sticks, so looks like I'll be contacting them now.
 
memtest checks for errors while orthos will stress your ram/cpu... seems like a temperature issue. maybe try underclocking your cpu/ram in the bios? if it even allows it.

those temps are pretty high :|

it's hard to pinpoint what component if any is malfunctioning...
 
those temps are high I agree, but you can't always trust sensor readings either

keep in mind it is a laptop so hot temps are expected, and mine is barebones with good thermal paste instead of stock thermal pad so stock DURABOOK would normally run hotter

I can pass the Blend test with only 1 stick of ram, but I get the lockup with 2 so I've pinpointed it to that. I've emailed crucial, but I will continue to test.

Unfortunatley the BIOS loaded on this is super crippled with pretty much nothing to adjust except boot order, etc.
 
I think the alarming ACPI temp must be like 30ish degrees too high.
When I do a cold boot if it says something like 58 when the mobo should be colder than everything else at that point.
The core temps should be just about the hottest thing at any point, so 86 degrees is pretty unrealistic when the cores just reach 69 under the most intense load.

Thanks for recommending me that Orthos test. I've never used it before until now. I thought all I had to do to test RAM was run memtest :eek:
