help: monitor blank after disk checking

Hi, I have a really strange problem.

My pc starts up normally, until after disk checking....

right after disk checking is done, the monitor is just blank!

We brought it to the repair shop but when they hooked it up, it was perfectly fine. They even accessed device manager and saw no error icons.

But when I brought it home and hooked it up, ... same problem!

MSI K8M Neo-V, VIA K8M800 + 8237 chipset
Sapphire Atlantis Radeon 9600 256MB

forgot to say - to get into safe mode keep pressing F8 just after all the initial POST information (memory test etc).

You should get a menu pop up offering safe mode as an option.

Voltmodded Sapphire 9800Pro @ 450/350 w/ modded VGA silencer 3.

oh, and I forgot to mention that I just reformatted that pc.

After the reformat, everything is fine. I am able to get to my desktop.

The trouble begins once I restart.

hmm... come to think of it maybe it's because I used my special winxp installer, one that installs unattended and has a slipstreamed SP2. But the thing is, I created that cd based on my OTHER pc, which uses a much newer monitor. (maybe the settings of the newer monitor got "imprinted" on the unattended installer?)

aaaahhhhh........

it was the monitor all along .... (my 9 year old monitor)

(What a damn coincidence ... my monitor breaks down the same time my LAN goes awry hehe)
