Problem now solved.

Hello . . .
I've got a mining rig set up with the following:

Intel Celeron E3400 1.6Ghz CPU
Gigabyte GA-EP45-DS3R with 4GB RAM
2x7950 HIS IceQ with 3GB RAM running at 1000/500 with fan speed 75%
1x6950 HIS Radeon with 2GB RAM, running at 850/500 with a fan speed of 80%
1xFGPA Butterfly labs bitforce single
1200w Corsair Power Supply

For the bitforce single we use UFA soft and it seems to run fine.
For the GPU's we use Phoenix 2.0 and have tried both autoconfigure and various more specific settings, like packet size 256 and 11-12 in agression.
We've tried each card individually and all together and right now I'm trying to get the two 7950's to work alone, before I attach the bitforce single or the 6950.  
The thing is, it ran for quite some time without problems and now it crashes the computer, sometimes before it even starts mining and windows is still in its start up fase, sometimes without mining after a certain time and sometimes after it has started mining, though mining will crash it faster.
I've had several burned out cards, but it seems that all cards are OK now and that something else is wrong - I doubt it's the mining software, which leads me to believe it might be a MB issue?

ANY and all help will be greatly appreciated...

  Didn't you post this?

  "Please start a new thread or use PMs.

  Stay on topic"

  Yes on Windows and now GPU's are detected, but still on start up 3 of the 4 Phoenix miners close down right away.

 SORRY FOR HIJACKING THREAD

  Despite being rubbish with computers i've been mining for over a year and just replaced 2 of 4 x gpu's, 2 new gpu's dont seem to mine for some reason, Phoenix for 4 devices opens but then all close again.
  Old gpu mines with extender in small slot but nothing mines from pcie slot, and new gpu wont mine from either slot.

   I'm based Suan Luang, any of you able to come out for a look in exchange for cold hard coins or bahts?

  So i'm pretty rubbish with computers and friend of mine help me set up my miner over a year ago

  2 x 6950 (Gigabyte)
  2 x 6950 (H.I.S.)

  1 x BFL Single

   After over a year of mining and hardly any issues, 2 6950's kept dying, so other week upgraded to 2 x 7950's.

   Tried installing the 2 new cards and now no GPU will be detected in the PCIe slots, only detected with the extenders in the small slots but wont mine.

   4 x Phoenix open to mine but all close down even with the 1 x 7950 detected in the slot that old 6950 still mines from.

   And sometime in the past week one of the old 6950 (Gigabyte) cards has stopped mining, still working just Phoenix window wont open and mine.

  Basically after someone who has some experience setting up a miner in BKK and is willing to come out to have a look at it and get it back up and running or suggestions through this forum.

   I'm Suan Luang area and will pay BTC or Baht to get me back up and running.

 Friend of friend says it would be great to be able to trace ip from transactions and claims to know a way to implement it.

  As the title says is it possible to find someone's ip address from block explorer and if not would this be a useful function?

 So i think its the RAM issue, system says running 4GB, 3GB usable. Just checked machine and says online, the minute i click on something i get the "not responding" msg and have to close it down.

   I have an older Armory (0.82.2) running on my laptop which does have 4GB RAM and i used last year. So taking into account i'm pretty computer spaz, to get back my 5 BTC do i copy the Armory.wallet file into Armory on my laptop?

   thanks again.

 Thanks for reassuring news the 5 aren't lost.

   Machine does have 4 Gb of RAM but its a damn slow machine, possibly due to rubbish CPU.

   Armory still showing "scanning block chain" but under that it says "connected 0 blocks".

    I'll get back on it tomorrow, late here and off to bed.

    Thanks for speedy response and your work on Armory.

  So i've been mining for quite some time but still quite rubbish with computers.

 This morning i downloaded Armory to machine and sent 5 BTC, i got the scanning block chain for about 1hr and then a not responding msg, finally synced briefly but no sign of BTC in wallet and then get a Armory not responding msg again.

  When i look in Blockchain.info i can see the 5 BTC transfer with 77 confirmations, but no sign of them in Armory. In other posts i see people mentioning doing a rescan, how do i do that with Windows 7?

  Thanks in advance for help and please bear with me, i'm sure i'll have a question regarding possible fix's.

  P.S. Used Armory last year on my laptop quite a bit and really liked it, bit disappointed its not working so great now and more importantly to have possibly lost 5 BTC.

  Tried placing an order for 2nd batch of batch #2, 15mins after opening, order 312 of 330 and it says "dont have stock, update cart", did this 3 times then received out of stock message. After initial F&%K up with batch #2 seems Avalon aren't prepared to test or use same payment method for all batch's.

   

  My fingers clearly not on the pulse, i was under the impression that they were going to release the bASIC under new management until today. Had it been under new management i would of waited for the bASIC to be released, this clearly changes things.

   How are you guys asking for refunds, direct contact with Tom/Dave or through CC companies?

   My order number: 1254
   Date order placed: 8/10/12
   Outstanding refund for bASIC $1099

   Just emailed Tom and Dave to see whats going on, as in btcFPGA forum, Dave said all CC refunds had been processed as end January.

   Dave if you see this any update would be much appreciated, before i contact CC company about refund.

  UPDATE: Spoken with Bank and refund received. Thanks Dave.

    So seems i'm also a little paranoid, Avalon address is listed as Albany NY and btcFPGA, people should be avoiding were only couple of hundred KMs away in Hannibal, NY.

 I read somewhere that BFL weren't going to mine but make money just from selling their hardware, this seems to prove otherwise:

 Last drop before going on the Bay, 5.5 BTC.

  I live in Bangkok, highest tech glass cleaner here is newspaper. I was thinking new pic looked better do you think still looks dirty?

   Thanks for input though.

 
   More recent photo of screen looking bit cleaner.

   It's either dried soap, limescale or general grime, well done finding my other post on Watchuseek forum.

 BUMP.
