Hi,

The last view months a problem developed on my system, when gaming, i occasionally get a BSOD.. ..but not a normal one, a BSOD wich is made up of blue and black bars and all the letters are white blocks, and sometimes the blue lines are purple!

So obviously i drew the conclusion that my GTX 285 was the problem, The last 2 weeks the problem seems to have worsened, BSODs/PSODs are getting more frequent..

Today however i got a PSOD while i wasnt gaming, i was just browsing the internet while downloading something using Alt.Binz + some mp3s i had playing in the background...

Now for the strange part; after reboot, i see some icons missing tot he right of the taskbar, + the time/date was set for 23:00, Dec 31 2009!

So my quess would be something happened to the CMOS battery, could it be a PSU problem afterall?

What do you guys think?


Thanks in advance.

Artifacts on screen is generally a sign of faulty or overheating graphics card.
The time/date resetting is a sign of failed CMOS battery.
If the CMOS battery has failed then any BIOS settings you may have made to suit your specific requirements may have been lost and reset to default values. This may or may not be a contributing factor to your graphics problem.

Are the system specs listed in your signature space correct and current? If so I would question your decision to run your data storage drives "2x 320GB,16MB"
as a RAID 0 array. Presume this shows as a single 640gb drive?

You do realize that if any problem develops with either of those disks you lose all data.

Why would you suspect the powersupply? It has 6 separate +12V rails each with 20A max output and efficiency rating around 83%.

Have you checked that the load is spread and balanced and that no individual rail is being overworked?

The graphics card seems to be a hungry beast too. The manufacturer's detailed spec lists maximum power @ 640w. That would require 53amps @ 12V
Do you have the supplementary 12V power connected to the graphics card with nothing else hanging off that rail?

Hello Richard59,
thnx for the reply,

The bios settings have remained as i set them, they are fine.. only the time and date seems to have been corrupted...

As for the powersupply, it has 6 individual PCI-E connectors which come straight out of the PSU, i use two of those for the graphicscard, so no other devices are or can be hooked up on those cables, also, it has worked fine before for a long time.

Though since my last post the system crashed 3 more times, at all times i was trying to finish downloading a movie using alt.binz, which utilizes alot of CPU percentage, the CPU is prime stable though...

Oh, and about the raid setup, I use it for installing games on, nothing valuable is on there, but thanks for the warning.

Well.. its not the graphics card...

I swapped my GTX 285 for an 8800 GTX, after 15mins of downloading it crashed again, this time with a red & yellow bsod, which was also common with the 285..

I also noticed that when i run my CPU fan @ lower rpm, it seems to crash much more frequent then when @ high rpm, so could this be a temp issue?
If it is, i dont get it, temp seems fine, i've also monitored it while gaming, videocard temp and chassis airflow are good aswell, when downloading CPU temp does not go over 48c (it gets this high because Alt.Binz decodes & extracts the packages right away while downloading)...
But even if it was overheating, arent Intel cpus not supposed to clock down & eventually shut down when overheating?

So i'm really not sure what is going on here, i ruled out the video card, also tried other memory, so that only leaves the PSU, CPU and mobo as a suspect...

Please help!


thanks.

If those temps are accurate then it shouldn't be the CPU causing your problem.
I would suspect the motherboard. It may have a damaged circuit that opens up under higher temperature causing the crash. Those types of faults are almost impossible to detect and would have been there from manufacture. Only other possibility I would suggest is to look for bulging or leaking capacitors. (in the powersupply as well as the motherboard). A skilled technician may be able to replace any found.
