I'm throw my media box through the window.
I've tried to reinstall KnoppMyth with R5A30.1 and an old error re-appeared.
(see this thread)

I've almost disabled everything in the bios. Nothing changed. I used PowerMax from Maxtor to test my drive (Burn In test for 8 hours). I got no error.

to sum up:

MemTest says no errors after 8 hours.
OCCT says no errors after 10 hours.
PowerMax says no errors after 8 hours.
My system does work very well under XP.


What the $%&?# is going on with my system and KnoppMyth?

I have two options in the bios that look like this option
CPU Disconnect
and
CPU thermal Throttling

I've just disabled both to be sure.



My memory is known to be cheap and may make nforce2 mobos crash especially when Dual Channel is on (my case).
The timing are set to optimal. I didn't look what they are.
BUT I ran MemTest for more than 8 hours and it said everything was OK.
BTW I tried without Dual Channel.



Me neither



Everything is new
Motherboard was used, but I returned to RMA because I thought it was the problem. They returned a new one.
FX 5200 is used, but I don't think it can be a problem.
I want to change the PSU. It's a 350 which came with my HTPC Case. But it's too noisy and I read somewhere that it was just a crap (yeah... for a 170$ case, it was not a good news)
I'm gonna try to change RAM by another. But $$$$$$ ...

You say your system works fine under XP, but is it running a a PVR server with clients attached as the same system is under KnoppMyth ?

What I mean is, it sounds like you have a myth client connecting to a myth server and the server is crashing ? Or locking up forcing hard boot ?

Can you try not having ANY clients connect to it, just let the Myth Server run for a bit. Maybe a week or two. No clients. See how that works and report back.

WantPVR, yes it's a client/server machine. I have no other client which connects to this server. I could stop the front-end on it if only I could reinstall the system.
For now, I'm stuck at the installation. (I can't reinstall the system because it says root has illegal blocks and askes me to repair manually, but partitions have just been formatted. Look at my other thread).

I guess there is something broken or not supported under Linux on my system but I don't know what.

I did not see the full specs for your machine in either thread. What exactly do you have in your box?

my config:
motherboard : Abit AN7 v1 Bios 19
RAM : 2*512 Elixir RAM DDR400 (dual channel enabled)
Sempron 2800+ OEM (2.0 Ghz, 333Mhz , 256 Kb)
HDD : Maxtor DM10 250 GB PATA133 16MB cache (Primary Master)
Optical Drive : Pioneer DVR-110D
TV Card : Hauppage WinTV 150 non MCE with transmitter and receiver
Case : Ahanix D.Vine 4 (PSU ahanix 350W)
Nvidia FX 5200

I'm gonna try to change RAM to Kingston. I'd like to buy a phantom PSU from Antec. (mine makes too much noise because there is lots of heat in the case about 55°C).

I can't see a problem with any of the components offhand other than perhaps the pata drive. It just seems like I recently saw another thread about problems with a pata. But I can't remember what it was about. You may want to run a search of the forums with pata as your keyword to see if that tells you anything.

why pata could be a problem? it's ata133. I had a sata before which gave me headaches.

Anyway thanks for the tip. I'm gonna search.

Well the search may yield you insight into various hard drive difficulties, but my post was based on a brain fart - thinking sata while seeing and typing pata. Sorry on that one.

I'm gonna try another cable to my drive.

I tried another IDE cable (attached to the hard drive) and the installation was ok. I was so happy.
Just to be sure. I restarted the installation , and everything was ok again.
So I tried to reinstall with my first cable and I got the error of "bad blocks" in Root.
Then I reinstalled with the new cable and you know WHAT? The installation failed. I got the same error "bad blocks". I gave up.

Check for physical contamination. Get a strong light, preferably a flash light, and possibly a maginifying glass. Unplug the cable and check the connector on the motherboard. Look for bent pins, debris, dirt, flecks of metal, ... Also check the card edge connector on the drive, you can clean it with a soft pencil eraser (pink pearl or white draftsmans) if it's dirty. Finally check the interior of that connector on the cable for any crud. The last couple really bizarre problems I had were from a nicked drive cable and a fleck of aluminum in a DIMM socket respectively...

Are these "cloop errors"? If so, bad burn.

cesman : I've tested the CD with testcd command and I looked at the checksum. Everything was OK. And I burnt the iso on two differents CDs. Same problems. (Besides, I don't what are "cloop errors" )

tjc : I have a pressurized duster, I'm gonna use it on connectors (motherboard and cable).

Ok, I'm not sure I found the problem but it seems that I'm not far.
I remembered my first installation was OK and I remembered that I used an old IDE cable to connect my DVD drive to the mobo. I didn't have a 80 pin ata133 cable at this moment, but I wanted a round cable and I wanted to use the full speed of my DVD drive (for burning and importing music). Then I bought a round ata133 cable and used it for the DVD drive. But I changed the CPU and the motherboard in the same time when my problems began.

To sum up. I removed the new IDE cable and reused the old ata33 one.
I could go through the installation without problems. To be sure, I tried 3 installations in a row and all of them were OK.

Now, I'm trying to test the stability of the system by encoding music and recording TV in the same time.

My DVD drive is a Pioneer DVR-110R and its firmware is old. (v 1.08 ). It seems that this drive is known to have problems to read some burnt CDs or DVDs (even its own burnt CDs and DVDs). Now the newest version is 1.37.



Maybe it can be the cause of all my problems. Because it doesn't install the system very well, my system can crash and it can cause my installation problem as well. is it correct? Is it possible?

Maybe it can't read well at full speed.
I don't think my round cable is bad because it's new.

Later I will retry to reinstall with my new cable to see what happens
