Problem Found

Motherboard was the most likely suspect (swapped everything else out one by one and at the end was still crashing). I have returned and am looking for some other mini-itx board with a different layout.

Problem Found

Begin Update2

Ok, at first I thought it was the Power Draw was exceeding or something, so I set about undervolting, I have managed to reach as low as 0.980 Vcore with Prime95 Stable, still happened, so I raised the vcore upto 1.000 and now, I am Prime95 stable with 94 Watts Max draw (according to the Kill-A-Watt at the wall) and it still happened once. I have no idea what could be wrong.

I do not this it is the temps. Coretemp reports a Max (in the last 12 hours that it has been under Prime95 as 75C, now its at 68C.

End Update 2
-----------------------
Begin Update1

OK, I seem to be having a weird issue. The apparent light flicker is the autofocus trying to keep up with the screen flashing. So no worries there. This just happens all of a sudden. This happened at all stock settings. Nothing was changed. I rebooted in the bios anyway and loaded safe defaults. This seems to happen very randomly. I have windows updated with latest drivers and no programs. This is a bare windows install while I play around with vcore (trying to lower it). No error messages, no response whatsoever. The only thing that works is a full power-off power-on cycle. Any ideas? Please check out the vid I made of the screen going schizophrenic.


I don't know how to embed video into the post.

Edit: When I go close to the Kill-A-Watt near the end of the video, I am trying to show Watts while this is happening. It reads 38 watts (my cellphone is pants at taking video)

End Update 1

------------------------------------------------------

I am preparing a mini-itx system and I now have only the case to decide on. I am most likely going to get the ISK 310-150 for my build. The component list is as follows:

Gigabyte H67N-USB3-B3 mini-itx motherboard (might upgrade later to a Z** mini-itx later)
Core i5 2500k
2x4GB Ripjaws (if they fit, if not then I'll stick with my current 2x2GB XMS3)
1x 64GB SSD (looking to buy the newer 6gbps ones, currently have a 64GB Microcenter rebranded A-Data S599 SSD)
1x 500GB 2.5" platter based
1x 5.25" DVD-RW Notebook drive
Onboard graphic.
Win 7 Pro 64

A home computer mostly for browsing, document work and mp3's, with some HULU and Netflix videos thrown in.

The case I want comes with 150 watt PSU.

I do not know how to read that and was looking around for reviews, but they are very scarce and hardly anything on the PSU. Will this be OK? Is this a proprietary size PSU? Can I look for other ATX Flex PSU's? Is this good enough for my usage and components?

CPU is rated up to 95W, which is most of your 120W available on the 12v rail. Add in video and other sauce, you might want to consider more power.

You probably could get by without too much danger, just refrain from Prime95 on all 4 cores :p

No vid card, Internal is OK for me, 3 peripherals (2x 2.5" and 1x 5.25" slim DVD), nothing else. That is why I want to know if its possible to upgrade the PSU (proprietary?), or get a better quality DC-DC unit.

Its a good sign that the word Antec is on that PSU, but still it seems like too close for comfort. Chances are you could get by with that PSU and have no problems, but yes deffinately no OCing and Prime95/F@H for that box.

I probably may underclock/undervolt.

It should be fine. Buy a new PSU if it dies out of warranty. 150W should be fine for such a setup unless the whole purpose of the computer is to run stress tests 24/7 for the next few years.

O well, ordered the case. I'll check out the dimensions of the psu and see if there is anything with more wattage available.

Specs:
Antec ISK 300-150 mini-itx case
Gigabyte H67N-USB3-B3 ($25 New user newegg coupon)
Intel i5 2500k (from last weeks 1TB HD + i5 2500k deal)
2x4GB Corsair XMS3 (another hot deal)
1x64GB SF-1200 Based SSD (hot deal)
1x500GB 2.5" platter (pending)
1x 5.25" slim DVD-RW (pending)
Internal 150W PSU (included with case)

The motherboard is the worst to pair with this case (all the headers i.e. sata, power, front panel, etc. are right next to the lone exhaust fan in the case), I have yet to play with undervolting the CPU, but stock everything (stock thermal paste with stock HSF and stock single exhaust) my temps reached as high as 80 with Prime95 and power draw never passed the 123 Watts at the wall (using the P3 Kill-A-Watt) and normal usage shows about 40 or so watts with light load (browsers with flash and the like, total idle is about 34 watts. I will get a chance to play with it tomorrow to see if I can bring the VCore down a bit, but the case is tiny, it fits vertically in the CD Tower Rack on my desk. It is very very snappy (even with a lone Kingston SSD, which I will most likely upgrade to an Intel 510 series), and fairly quiet (I do not need extreme silence).

Hi gamefreakcgbm

I have the same problem you reported, same motherboard and proc, GSkill memory, Vertex 2 SSD. The most frustrating is that the system boots normally and the system begins flickering after 1 minute or so...

I have confirmed it with W7 64 bit and Linux (Ubuntu 11.04) 32 bit. Older versions of Ubuntu work, probably because of a less evolved driver. Especially, 10.10 recognizes native monitor reolution (1080p) and does not have the problem.

Have you found a solution ? Or have you changed the motherboard ? if so, which one did you take ?

I think I will try next with discrete graphics...
