Hey guys

Let me start out with my specs

MB: ASUS P5N32-E SLI
CPU: Pentium E6600
GPU: EN8800GTX
RAM: Corsair XMS2 6400 2x1GB
PSU: Tagan TG800-U25

I've been having a weird pc freeze as of late.

It all started with this blue screen:

"A problem has been detected and windows has been shut down to prevent damage to your computer.

MACHINE_CHECK.EXCEPTION

If this is the first time you’ve seen this stop error screen, restart your computer. If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any windows updates you might need.

If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use safe mode to remove or disable components, restart your computer, press F8 to select advanced start up options, and then select safe mode.

After this it all went downhill:

I got this screen a couple of times afterwards, and also other stuff seemed to stop working. Mainly my keyboard and mouse. But as you read further this might not be the case because what i saw was maybe just the last image stored in my pc being displayed on screen, so that's why it seemed the keyboard+mouse didn't work any more.
Because after this happening a few times, keyboard+mouse crap out and the blue screens, my pc would start to hang at weird places. In the middle of my MB intro video, at the end (when it says press del to enter bios), sometimes there is no image displayed at all on my monitor, but the system has power. It hangs in the BIOS if i get there, keyboard 'stops' working. I also get a system boot disk failure (whether my HD's are connected or not) if i get passed the MB intro.
Each time i also have to really cut out the power, hold 'on' button for 4 secs, or just flick the switch at the back.

I have tested if my RAM sticks don't work, but the problems don't seem to differ.
As for testing PSU/CPU/MB i have not a clue how...

Does any1 have any insight into what might be the problem here?

thx in advance :)

You can get a thorough system test suite in UBCD (Ultimate Bood CD). The self-booting CD tests multiple system components: memory, CPU, hard drives, peripherals, etc. It does a very thorough job and is extremely easy to use.

Although it's reported version ver4.1.2 is available, the latest version I could obtain was 4.1.1
http://ubcd.sourceforge.net/
http://ubcd.sourceforge.net/download.html
You can download a .iso, .exe self-extracting, or .zip file depending on what connection speed you have. (download filesizes range from 87mb to 115mb) The .iso file is easiest as you just download it and then burn the .iso image to a CD using Nero, or CDburnerXP, or burnatonce, etc.

MD5/SHA-1 Hash Verification
I do recommend performing a hash verification to make sure your downloads aren't corrupted. Long downloads tend to be somewhat vulnerable. Use a program like freeware Fingerprint to calculate the MD5 hash and compare to the value provided by the download site.

I recommend initial testing be conducted with the hard drives disconnected from the system.

I just went through this with an almost EOL machine.

I'm not sure what caused my problem but I narrowed it down to being my IDE devices suddenly causing a problem with Windows. Could have been an update for the OS or the way the OS handles the BIOS. I diagnosed this by pulling all the IDE devices but the OS HDD and the machine booted without problem. So I at least knew where to start looking.

Previously I ran everything configured to CS (Cable Select). My fix was to set each physical device with their jumper as either MA (Master) or SL (Slave). After doing that I still had problems until I connected the MA set device to the connector at the end of the IDE cable and the SL set device to the connector in the middle. I didn't realize before that that it mattered which device went where on the IDE cable but I guess it does.

Anyway all things fixed and no problems since then even after multiple reboots and days of uptime.

I guess this could be OS related as I mentioned or maybe my IDE controller has issues or one maybe more of the devices was not signaling correctly when set to CS mode.

Putting the master drive on the end of the cable is done for electrical engineering reasons in cases when you don't have a second drive connected to the same cable. It has to do with signal quality of the data and control I/O lines. You always want at least one drive at the end of the cable when the IDE port is used. If interested, it comes under the category of transmission line effects.

And yes, the master/slave select can depend on cable position as well. Contrary to what some people say, it can pay to read the instructions.:O

Glad you got things resolved.
