Hello, Thanks in advance for any wisdom or suggestions - I am sorry for such
a long post.
I own (2) K7S5A (Rev 3.1) based systems that have performed very well for a
couple of years now, yes of course both boards had to be re-capped about 6
months ago - but I have to say they have both been VERY stable.
I decided it was time to see how I liked Windows XP Media Center Edition
2005, so here is what I did:
I took my exisiting VERY STABLE "poor mans" Multimedia system running
Windows XP Pro - and removed the TV Wonder VE card.
Here is the system configuration.
ECS K7S5A Revision 3.1 - Last Official BIOS (030811) Stable - (Re-capped),
suing on board LAN.
384MB of Generic PC2100 RAM
MSI/NVIDIA MX4000 128MB Graphics card.
Seagate 40Gig 7200 RPM HD ST340016A (Primary - Master)
Artec DHM-G48RC 16x DVD ROM (Secondary - Master)
1.44 Floppy drive
Antec SL300S Power Supply.
Creative Soundblaster Live 5.1 Sound Card.
I installed Windows XP Media Center Edition 2005, installed latest updates,
latest MCE compatible video drivers, WInDVD 6 DVD Codec - Decoder. Ran the
system for about 2 weeks, very stable.
Purchase a brand new retail EVGA NVTV Single Tuner card.
HERE IS THE PROBLEM
With the NVTV installed in ANY PCI slot, the SECONDARY IDE controller won't
detect any devices if the system is first powered on.
I disabled just about everything in setup, both serial ports, the parallel
port, the midi controller, one board sound had been disabled. Pulled the
Sound Blaster - tried every slot - still would not detect the devices on the
secondary IDE controller.
Tried changing RAM settings to safe, tried the bus speed at 100 Mhz, still
no luck. I disabled the 2nd IDE channel - moved the NVTV card to the
secondary on the primary controller. Disabled the
Installed the drivers for the NVTV card, the system locked up within 5
minutes - even when not running Media Center - it will lock up in IE or even
just idle. Almost everything has its own IRQ, the video card is on 11 and
the NVTV is 3 - moved the NVTV to other slots, still the PC locks up.
I disabled the on board IDE and used a Promise PCI IDE controller - detects
drives on both IDE channels as it should - system still locks up.
IF I DISABLE THE NVTV CARD in Device manager - the system is stable.
I removed the Promise card and put the drives back to hard drive as primary
master, and DVD secondary master. I noticed that if I disabled the the NVTV
card in device manager and rebooted - the motherboard would detect the DVD
drive on the secondary IDE controller at POST!
I updated more drivers, tried older drivers for the video card, tried almost
every hacked K7S5A BIOS - the system still locks up!
I don' recommend this for kids but if I boot the system and simply start
explorer and the NVTV card is enabled - the system will lock is anywhere
between 5 and 15 minutes - IF I PULL THE NVTV CARD OUT QUICKLY AND
STRAIGHT - THE SYSTEM WILL NO LONGER BE LOCKED UP. I have only done this
twice and realize its risky.
This same issues happens with my another K7S5A (3.1) system also - does
anyone have a K7S5A with this tuner - is this an issue between the NVTV and
the SIS 735 chipset - I have seen issues with the NVTV and VIA chipsets?
I have tried even more things than I can post here, I won't say I have
"tried everything" because if I did - it would obiously be working.
HELP - Dave
