653976 2008-03-29 07:05:00 Hello,

I went to upgrade my video card from an MSI NX6600Le to Asus EN8500GT Silent/* 512 today. Here was my procedure:

1) uninstalled video card Nvidia drivers
2) replaced card with new model
3) booted up but no video signal
4) reinstalled original card & booted up fine
5) reinstalled new card: same issue
6) refit original card again but now no video signal with this card

I then started getting constant reboots using case switch; had to turn off at PSU. All chassis, CPU, PSU fans working. HDD drives spinning up. Upon firat boot in (6) it booted up to full login as I heard my startup audio -no video. I tried clearing CMOS but then unable to boot up as probably booting into CMOS.

I removed the mobo from the case, setup on a cardboard platform, connected PSU & video card with connection to CRT TV composite, then VGA to projector. When I first turned on the PSU it began booting instantly without bridging the power terminals. Still no video.

What now! Thanks. Could the mobo somehow be shorted as I heard a slight crack (no worse than has happened on various boards I have worked in the past) when completing (5)? I believe the constant reboots were present before the crack; I think.

Here is my config:

AMD643000+ CPU (not O/Ced)
Zalman 7000B-ALCu CPU cooler
MSI K8N NEO4-F mobo 22/6/06 1D BIOS
MSINX6600LE video card
2X Hauppauge 150MCE tuner cards
Winfast TV2000XP Deluxe tuner card (no drivers installed)
1GB DDR400 Ram
1X SATA 500GB HDD-3X partitions incl. 16GB boot
1X SATA 110 HDD -single partition for TV records
1X SATA 160GB HDD -2X partitions
Silverstone SST-ST400 PSU (new)
Benq DW1640 DVD-RW
Asus E616 DVD Rom
Silverstone LC14 HTPC case
Win MCE2005

653978 2008-03-29 07:34:00 The Winfast tuner, wont work with Windows MCE.

I would unplug some of those for now and then see if it boots

The system has worked fine for over two years. The mobo setup on the cardboard was with no PCI slots used. Same issue. Thanks.

Yes it is. But why the issue with the original card? & how to fix it? Thanks.

653982 2008-03-29 09:11:00 Also, The card is advertised on the Asus website as compatible with both XP & 2000. And, the PC should as least get throught POST even if the new card is not compatible with the OS. gkar (5215)

Ooooh . Have you answer the question yourself?, check the board .
I'm a bit confused with where you are at now, on cardboard, psu and cpu installed, is the board booting? . . .

I have to say, I dont tend to get any boards making cracks when working on them, your comment about normal sounds of cracking when working on mobo is concerning . . . .

How? As I'm not a technician . What next for a logical test?


I'm a bit confused with where you are at now, on cardboard, psu and cpu installed, is the board booting? . . . A while back I was informed one test method was to remove the mobo from the case, install only PSU & video card . Use a screwdriver to bridge the power switch terminals . This is used to determine if the mobo is shorting on its risers inside the case . [/QUOTE]


I have to say, I dont tend to get any boards making cracks when working on them, your comment about normal sounds of cracking when working on mobo is concerning . . . .

Maybe 'cracks' is slightly over-emphasised . I mean I have struck the odd board which has more resistance to insert the cards into PCI, AGP slots -and no, the cards are not misaligned . But I did hear a slight noise (crack was the simplest, if misleading, way to describe it) . As stated, there is no visible, physical damage .

And I do believe it worked with the original video card after I heard the noise . Thanks .

653985 2008-03-30 06:08:00 When u cleared the BIOS/CMOS did you remove a jumper?

If you did, did you put it back on the right set of pins?

And when you took it out of the case, did u put the ATX 12v plug in, if it uses it?
