I've been having variations of this problem for a while now and to this day the solution eludes me.

It happens a majority of the time- but not always- I boot the system and it runs up to the desktop. After a few seconds, the monitor loses all signal from the computer and my rig starts making horribly loud sounds I can hear from down the hall! No solution after that but force shutdown.

Originally I had a similar problem but the system never even got to the boot stage.

Worst part is, nobody seems to recognise or even know of a similar issue.
 
what have you done to diagnose this?
you say there is a loud noise, from where? does it sound like a fan or something else?
does it give any other errors at all?
on startup after forced shutdown does it come up with the usual repair windows/boot normally screen or just go straight back into loading windows?
has anything been done to the computer around the time the problem occured?
 
It gives no form or option of diagnoses.

When the screen goes black the monitor cuts out completely, there are no beeps or special lights save for the ones that indicate the machine is running. I can only assume the noise is from a fan- but its very hard to tell what. I want to say the case fans though, because it is VERY loud, and I can't imagine the GPU fan could do that (at least I sorely hope not).

When I reload it usually just asks if I want to start windows normally. On occasion, like now, the system has booted and nothing has gone wrong. Most of the time sadly that's not the case.

The only alteration I've made to the computer since having it was using a modded 6950 bios, but that was a long time ago, before this problem started.
 
What Graphics card have u got
what PSU have u got
What ram have u got

Sounds to me like either the psu is not running your graphics card OR the graphics card is failing

Is it on the rig in your sig ?
If so try just one card and see what happens if it happens with one try the other one if it still happens then is it possible to test your cards on another rig to rule out any failuer with them

With ram it either wont give you a screen at all on boot up and would normally give a beep code to let you know its ram OR it would cause BSOD in windows or system lockups

CPU can also stop the monitor coming on at boot but normally fans rev and slow then rev and slow continuasly
but since you get the main screen and then it go's of it sounds like graphics cards to me also that loud noise is most probly the cards fan going 100% when it fails

How do I enter event logs? That's not something I'm familiar with.

Following any kind of system check or hardware inspection I'm getting no errors at all. Not even any abnormal temperatures. Like I said, this one has me stumped...

i take it you flashed the cards bios to unlock them
hhhhm might be a baD BIOS (JUST A THOUGHT)
Click to expand...

he said it was running fine for a while though, so i would say that possibly damage has been done to the card, or maybe bad driver or windows corruption. or the card just isnt getting enough power all the time.
 
yeah defo to do with GPU in my opinion

i would run just one card for a day or two and see if it happens still if it is fine then swap them over and try the other and if that is fine then you know that they are all good and then run them again wwith FRESH drivers and if it happens again put an old hard drive in and install windows on it to rule out the OS then if it still happens i would then TRY a new PSU 1000w +

thats what i would do anyhows
Hope this helps a little

Could be an error with GCards ram etc or your system ram

Have you tried MEMTEST86 at bootup to see if you have ram issues with the system ram ?
 
from that, the kernel-power error is odd as it seems like it mainly relates laptops it seems as there is a lot mentioned about battery. the driverframework user-mode seems to point to an explorer issue or some form of windows error, so could be a simple software glitch. is a reinstall an option?
 
I suppose it could well be, but I'm perplexed that my system would work at all if that was the case. I can only assume the other answer might be a hardware error that just isn't registering under an event diagnosis...
Also seems to happen a lot less when I switch back to standard BIOS I notice, that could well be an indicator. What it has to do with the noise though I have little idea.

And thanks therutz for the advice, I might try a few of those...
 
when it does load normally, can you run things like 3dmark, WEI or something that will stress the cpu and gfx, atleast eliminate them. also if you can take the side of the case off when the noise starts and put your finger on the middle of the fans one by one to stop them for a short time, eliminate those too.
 
Alright I'll certainly give that a try.

I can usually run high end games for long periods without problems, but I'll try 3DMark or Kombuster and see if anything crops up from that.
