Hi all, I'm looking for a bit of advice before I get on to OC customer support just so I have an idea what my problem might be. I hope someone can suggest something...

I have a Battlefield War Rush Intel Core i7 2600K 3.40GHz @ 4.60GHz (bought March). It has Kingston Hyper X memory and a Palit (sold as OCUK) 560ti 2048mb. I also added a SSD (64mb OCZ I believe), and upgraded the motherboard (Asus) and power supply for adding a second card in the future.

Anyway, as of yesterday morning, I have a big problem, in that when using it, I just lose signal to the screen so the screen shuts down and goes into energy saving mode (as it would if I had shut the computer down). The computer just keeps on running, fans etc, so I'm sure it's a problem with the signal.This happened a few times on and off, then last night it happened and a restart wouldn't fix it. At the moment then, the computer doesn't work although when I get home later it may be fine for a while again.

I've checked all cabling etc but haven't had time to open her up and check the gfx card is seated properly - I'm sure it must be, it hasn't been knocked or anything.

One other thing is that when I power the pc down after it's done this, using the on/off swith, and then restart, the screen does come back to show the motherboard splash page and start windows in safe mode page. Then I hear the windows ditty, see the logo form and then the monitor goes off - essentially as Windows kicks in proper.

So, does anybody have any thoughts about what the issue may be? I'm not that technical but am happy to open it up and have a fiddle, but that's the extent of my capability.

Hope somebody can help :)
 
Take the Graphics Card out and try it with a new card to rule out it's not the actual card at fault. If you're using a USB cable for the monitor give it a minute to check that it goes onto the actual windows login screen since then it'll pick up your monitor and not before usually, you can change it for a vga cable if you have one then it should pick it up as you boot.
 
Dont be fooled into thinking this is nessasarily a loss of signal, I has a similar thing a while back with very similar symptoms and spent ages trying different monitors and Gcards and the only reason I realised it was not a loss of signal because I was listening to music when it happened once and it got stuck in a loop when the signal loss happened. Turned out it was a dodgy PSU.

Im not saying its not a signal loss all im saying is it could be your whole system crashing.
Have a look at your event viewer and see what that says, if it does show any errors at the times you get this problem it might be a good idea to get yourself a free blue screen viewer as the windows event viewer is very vauge.
If you do find its a system crash do the normal one stick of ram at a time and component testing
 
Thanks for the replies... it seems to be working tonight. I'm checking temps and it all seems ok. Don't really understand voltages though so that information in CPUID is lost on me - maybe it could help me understand if PSU is ok though? Does anybody know what I should look for?

I'm on a VGA cable but don't have access to another graphics card so can't really do that test I'm afraid.

I'm positive it's not a complete system crash, as the monitor just goes off like it would when I turn the pc off - showing up text saying energy saving mode - this is from the monitor, not the PC. The fans and drives just carry on as normal, no hint of blue screen etc before I lose signal. I will download a blue screen viewer though as I'm sure this problem is going to keep happening.

The only events around the time this was happening last night are ID 3 and 41. iD 3 seems bang on the times I had the problem, but I think it may have something to do with rebooting - which I was doing using the on/off button. My limited knowledge and research doesn't really link these events with the problem.

Just out of interest, I did notice I only have 1.5gb left on the SSD (bloody Armoured Kill). Could that couldn't be a possible cause?

Click to expand...

If you have your page file set high and on that drive I guess it may cause problems, but I would not have thought the problems you are experiencing, I would have thought it would have caused stuttering more than anything else but im guessing tbh
I think a lot of people disable page file swapping nowadays what with systems having loads of ram and fast SSD,s it might worth trying with it disabled as a test and see if it cures your problem, you can always re-enable it and it has not cost you anything
 
Hi all,

I've had to revive this thread as the problem went away but is now back. Boot SSD now has much less on it so I don't see that being a problem.

Just a recap... PC working fine, then at a touch of mouse the screen loses signal and goes to energy saving mode (Dell screen). On reboot (using power button to shut down), it goes as far as forming the windows logo, then loses signal again, but after monitor goes off I still hear the Windows ditty - therefore in my eyes, not a system crash, but a signal or card problem? Especially as fans and lights continue as normal.

Does anybody have further suggestions foron what the problem may be?

I was thinking I might remove the overclock. I remember there being a thread telling you how to remove the OC profile from an ASUS bios, is this a simple job?

Also, last night I was in the bios after it happened (bios works fine), and I click on something called OC [something]. The options were OK and cancel. I hit OK and now whenever I start the computer the fans come on once, then it all goes quiet again before booting again (still not booting to completion though).

Just an additional problem I've caused I expect, I think it may be OC turbo mode, does that sound about right?

Anyway, any help is really appreciated. PC is only 6 months old and I'd really like to get it fixed tonight. Aftermath :D

Thanks
 
Doesn't sound like a problem with your overclock tbh. Normally you'd get crashes or lock-ups if that were the case. What have you tried in the way of troubleshooting?

Have you tried using a VGA cable for the monitor? Reseated the gfx card? Tried a different gfx card?
 
You're most likely right about the OC, I just didn't know what else I could check from the BIOS though.

I haven't tried reseating the GFX card this time although I did last time and it didn't seem to have any affect. I will try tonight.

I have an 8800gt in an old dell (still haven't re-installed Windows and tried to sell it yet!), but I think that's AGP and not sure if my MB has a slot for that. Do modern MBs still have AGP? If so I could try that.

Also, last time it was happening the event viewer turned up nothing of interest.

That's about the extent of my troubleshooting though. It's hard because when it happens I obviously can't trouble shoot from Windows, and working in the BIOS without breaking something is impossible for a novice like myself!

I was wondering if my MB had internal graphics, but I only have the two video slots from the GFX card externally. Perhaps there would be an internal connector that I could plug the monitor into just to take the GFX card out of the equation for a test (rather than faffing with the 8800gt).

Finally, the power supply is a 650w OCZ. Not the top brand but I think it should be alright. Just mentioning that as sometimes power is the cause of all sorts of issues, but not sure if it's the case here.

Does anyone know if there is a way to test integartity of PSU or whether it's delivering enough power for 2 x SSD, 1 x 500gb HDD, 560 ti, 8 gig and i5 2600k.
