Screen goes black after login. Please help.

post #1 of 23
Thread Starter 
So last night I had played a couple of games (Duke Nukem Forever demo for like 20 minutes, then AvP DX11 for like 30-40 minutes) and then after I had finished playing, I started watching a TV show on Hulu and while I was watching my show, all of a sudden my screen goes black and shows no signal on my monitor.

I restart it and it makes 1 long beep then 3 short beeps. I turn it off then turn it back on again and it's fine until I login to windows, then the screen goes black again and the monitor goes into power saving mode. So I open up my pc to see if I can smell anything burnt or feel any hot air coming from the GPU. I can't, so I think the GPU is fine, but I've only had the gpu for about 2-4 weeks, and today was probably my longest gaming session, so I suspect that my gpu is involved in this problem.

Anyways, when I did have it open, I noticed my motherboards heatsync gets VERY hot pretty fast. I suspect that my old-ish motherboard can't handle this newer style graphics card and my gpu is causing my motherboard to overheat, but that's just a working theory, which is why I came here and decided to post and ask you guys.

Here are my specs:

Asus P5N-D 750i SLi motherboard (Socket 775)
EVGA GTX 460 SE
8gb DDR2 RAM
Intel Core 2 Quad Q6600 @ 2.4ghz (stock speeds, hasn't been overclocked)
1tb Samsung Spinpoint (don't think this matters, but I'll post it anyway)

Prior to this I had read something about bottleneck of newer cards on 775 motherboards, so do you think maybe it's my motherboard that's causing my video signal to go out, because my gpu doesn't feel hot when I put my hand under the fan. Or maybe the GPU PCI slot is overheating? Could you guys help me out? I'd really appreciate it. I'm guessing that I'm going to have to RMA my motherboard.

edit: Oh yeah, forgot to mention, I have all the latest drivers, and in fact I updated the driver to the new one after I started having the problem and got a little bit further (was actually able to see my desktop and everything for about 2 minutes before the screen went black again) so I'm fairly sure it's not the drivers.

Have you tried to see the gpu temp by using GPU-Z?
It could also be related to the memory installed. Try to use the pc by using only one stick, if all goes well then repeat that with the other sticks and see what happens.

Okay, I removed all but one stick, and it's on and hasn't shut off yet, but the motherboard heatsync is still pretty hot. Not as hot as before, but still pretty hot. I've opened up CPUID hardware monitor (I think it's similar to what you suggested) and it shows my gpu temperature at the most as 29 degrees celcius... wait, the screen just went black and the computer made a few beeps. 1 long beep and then about 5 short beeps. Okay, so the computer stayed on for about 10-13 minutes with only a 2gb stick in, but still eventually crashed.

The program showed my motherboard temps as being as high as 40 degrees celcius, but I don't think that was correct, as it felt pretty hot to the touch, but then again, I'm not sure what 40 degrees celcius feels like.

Okay, have you tried the same thing with the other memory sticks? If its a ram issue then you will find one or more stick/s which help the system run perfectly.

Which psu/smps are you using?

Okay, I swapped out the stick with a different one and put it in a different slot, and so far it's doing the same thing as the previous ram stick (staying on, but the heatsync on the motherboard is continuing to get hotter). I'll just wait and see if it eventually shuts off like before.

I don't know what "SMP" means, but my PSU is a Corsair TX 750w.

Not SMP, its SMPS which is another name for PSU. Anyway, I asked about the PSU because I thought it might be caused from a poor power supply. TX750 (old version I assume) is a decent PSU. And that heatsink overheating can be the result of high voltage. Can you go to the bios and note all the voltages.

Okay, it's been about 20-24 minutes now and it still hasn't shut off yet, that's like double the time of the previous stick. I did notice something about the stick, you see awhile ago, I only had 4gb of gskill ddr2 pc 6400, but one of them failed, so I sent in for a RMA and got a replacement, only the replacement had a blue circuit board on the pins or w/e, where as the ORIGINAL had a green circuit board. I also ordered some at a later time to upgrade to 8gb, and those newer ones ALSO had a blue circuit board. Obviously the color has nothing to do with it, but it indicated to me that they had maybe made a few revisions to that memory and maybe improved it in some way (that's just a guess, not 100% sure, but it would make sense), so maybe it's the RAM? I'll wait about an hour and if it doesn't shut off, I'll turn it off and stick in each of the other blue sticks one at a time and see if it shuts off after an hour then. And by the way, all of the RAM are the same specs, so it's not like I'm using different ram for each slot.


Just read your most recent comment. Should I check my voltages first or do what I posted in my comment? Also, I have a spare AX750W modular power supply brand new (which I got virtually for free), standing by just in case I NEED to switch them out. Actually, I had planned on doing it this weekend, but got sidetracked by this whole computer crashing issue.

Yeah, sorry, I briefly looked for it when I first signed up, but couldn't find it. I found it now though and have filled it out.

No, keep on with the testing. If it fails and/or you have to restart again, then check the voltages, or you can find them out from any system monitor software like hwmonitor. I just want to see if its overvoltage which is causing the nb chipset to overheat. Lets hope that it was one/two memory sticks which went bad.
OMG!!! you have a spare AX750. Its like saying you have a spare gold mine. That's one of my most favorite PSUs. Its far better than a TX750/850 in ripple suppression and power rating. Dude, try that PSU out the next chance you get.
