Really fed up now....

Sorry to revive a "dead" thread, just thought I'd update.

I took my PC to a local PC repair shop and they tested it overnight and 3 hours in the morning and couldn't replicate the fault, they said it ran perfectly (no bluscreen's or signal loss).

So How can it work fine elsewhere, but not in my home. Tried the PC upstairs and downstairs, with different kettle lead's and monitor leads ETC...

Any idea's? I think I'm going crazy here XD.
 
I wouldnt even normally think along these lines, but having quickly skimmed your last thread and then having a read of this.

Have you tried using a good quality surge protector between your PC / the power? If you dont have one do you have a firends / relatives you can take it to and see if it could, in some rather odd way, be your home power supply?
 
All PC related kit (PC, Monitor, Speakers, Printer ETC...) are usually connected into a surge protector, have also tried the PC and monitor without the surge protector and get the same result.

Not sure on the quality of the surge protector... it has 10 sockets and some other things like ethernet ports etc.. lol :)

Try setting your PC up in another room or taking it to another location. Could easily be power supply related how new is your home/wiring??
 
My home wiring is shockingly bad (bulbs going very often, my dvd tray on my surround sound opens by itself sometimes and a T.V in another room turns itself on sometimes, aswell as the Wii console.

Although saying that, I sometimes have LAN sessions at home (nerdy I know) and during those times there will be 3 other PC's in one room, pulling a total of about 1500W without issue, my PC in the same room on its own will only pull about 400W (using 1 graphics card) and has problems
So it seems my house can supply more than enough power, but the electrics are old and wired by my farther who is not an electrician.

Tried my PC in the living room, in a spare room and in my room, same result in all.
 
I don't mean any offence but in light of all the other electrical problems, money and time you have spent on your rig, might it be worth getting an electrician in just to check the state of the electrics in your home? This might be the problem, because it seems you've tried everything else possible, not to mention how patient you've been throughout the whole process.

No offence taken, its a good idea. I know a guy that lives a few doors down thats an electrician so I could ask him if he minds taking a few minutes to look at the electrics.
 
Dont think a surge protector will be enough, you would ideally need an active ups of some kind to manage power flow to not get issues. To confirm this just try your pc at someone elses house.

Also, if your at the end of an electrical line you will possibly get a lot of problems due to lots of people activating equipment before your home.

Good luck.
 
ive always used crossfire in the past without problems untill last time i tried with a pair of 6850's and everytime i started a game or benchmark i got an instant bsod, i got fed up in the end and sent them back and got a 6970 instead, well now im useing eyefinity i would like to get another 6970 but worried the same thing is going to happen, ive watched a few threads like this with intrest and the power sort of makes sense to me, i live in a 30's house with overhead cables that was rewired sometime in the 70's, got me thinking could this have been my problem

If I had to get an active UPS, how powerful do you think it would have to be?

Not very for a single PC system. http://www.overclockers.co.uk/showproduct.php?prodid=UP-035-AP I imagine this would do the job, along with giving you around 4 minutes of power if you pull the full 400 watts at a guess.

Its probably worth mentioning that I'm not in any way an electrician, given the other problems you mentioned I would get your house electrics inspected before dropping £80 on a UPS.

After all those "maybe it is this" or "try that" ... maybe instead do something completely different. Follow the evidence.

For example, somewhere long ago was mention of a BSOD with one file name. Did you see all those numbers? Facts that tell a fewer (who better know this stuff) what has failed. And where an analysis begins. Swapping parts only on speculation (also called shotgunning) has a nasty habit of exponentially complicating problems. Or cures symptoms – not the problem.

Start first with facts. For example, what was in the event (system) logs? Any problems reported in Device Manager? And what exactly are critical voltages when you have the machine doing as much as possible before crashing. IOW those three digit numbers must be measured with a digital multimeter on 20 VDC scale. Nothing else will do. Measurements are on any one red, orange, yellow, and purple where each wire connects a PSU to motherboard. Also useful would be numbers from gray and green wires.

For example, the purple wire must measure something around 5.0 VDC. But that actual number reports other useful information that many others would not realize.

And finally, better computer manufacturers provide comprehensive diagnostics for free. Windows works around or avoids problems. A diagnostic detects problems that do not or intermittently crash Windows. Diagnostics are mostly for rare events such as yours. All computer manufacturers have them. Only better manufacturers provide them for free.

Again, those numbers on a BSOD screen say almost everything about your problem. Other with least computer knowledge would ignore what they do not understand. Your help will only be as useful as numbers you first provide. Those who better know hardware will remain silent if you do not first provide facts that actually say so much more. Anything that has numbers is essential in order to "Follow the evidence".

If a UPS does anything, it is only curing a problem that still exists elsewhere. The job of a power system (which is more than just a supply) is to make all AC variances irrelevant. And provide rock solid DC voltages. A UPS is most often recommended when one has no idea how electricity or a power system works. Fix the actual problem. That starts with requested numbers.

Seems to all be ok now lads, I think its a dodgy extension cable, probably the CPU 8 pin. Its the only thing I hadn't tried without until yesturday, reason being is that the entension is needed as my case is huge, got my PSU mounted outside the case (on a work surface) and the 8 pin can now reach.
So yeah been working fine for 2 days straight, hours of codbo, metro 2033, unigene, 3dmark11, crysis warhead...
I'll have some cheap almost new HD6950's that have been flashed to 6970's on the bay tomorrow if anyone is in the market for one or two.

I'm gonna keep my GTX570 beasts as I have waterblocks for them already.

Thanks for everyone's help.
