PC Hanging on BOOTUP or maybe a TFT problem

I previously added this post as an add-on to another post but have decided to make it a stand alone post... here it is ................

Re: Philips 170B4 TFT Monitor stays in sleep mode after rest

I too am having a boot up problem and / or tft problem.

When i boot up pc the first screen showing all the Dos lines of info re pc info and hardware shows on TFT ok
And then before the next screen ( which should be the WINDOWS XP LOGO and blue loading sybols ) the pc either appears to hang or the screen is just blank and i cant change the blank screen image.
So because the screen is blank i dont know if it because the PHILIPS TFT 170B4 is at fault or if the boot up is just hanging after the initial first screen.
So i have to power off and try again ....
The problem is only intermittent and probably happening 20% of bootups. I have not had the hang up / blank screen problem wheni boot up in safe mode.
The TFT screen has never blanked out ever apart from during the boot up as detailed above... So come on guys do i have some sort of mother board/ or bios/ or TFT problems.
Your comments greatly appreciated.
Many thanks
Ken uk.

That seems to be the point at which

the system checks the DMI data [checks that the hardware is working]. Are you using the correct drivers for your LCD monitor??? Could be caused by any flaky hardware.

Also, try going up in Safe Mode and make sure that Device Manager doesn't have more than one driver for the monitor or video adapter. If there are multiple entries, delete ALL of them, reboot and install the correct drivers when Windows detects new hardware.

Interesting..... I have recently been into Device Manager and i did notice that there is an exact double entry there for my Philips 170b4 TFT.
Could this be the cause ?
If so should i just delete one of them ? Or do i delete both and then let PC find drivers on reboot?
Just a thought my TFT has the DVI connected , that wouldnt give the double entry would it ?
Thanks for your reply

ANY TIME one sees multiple entries in Device manager
by Ray Harinec / October 26, 2004 11:57 AM PDT

there can be more than two. ALWAYS remove them all [takes multiple steps, can't delete them all with one click].

If you leave one Windows will simply get confused again during the next boot.

Be certain to do this in Safe Mode. That is the only way to see all of the entries.

Remove both entries from there and reboot. When

Windows finds the "new" hardware, install the drivers that came with the monitor.

Sorry Ray not sure if you have mis understood me ??
I was trying to remove the items from device manager whilst in SAFE MODE as you originally advised .... but when i went to search for them in safe mode they were NOT LISTED in device manager.
So i booted up in full mode and there the two listings sit under MONITOR in DEVICE MANAGER...
Why dont they show in Safe Mode ??

I fully understood. I simply have no idea
by Ray Harinec / October 29, 2004 6:34 AM PDT

why it didn't show in Safe Mode, but ***-u-me that fact is related to the problem. Hopefully when you remove them in normal mode and get to install the drivers things will start working.

All this time I have been thinking that you are using the analog video connection. If you are using the DVI connection that may be different re the safe mode bit, I am not certain..

Further to my intial query.
I did not tidy up the device manager etc as an answer to the possible "fault".
I remembered that about a week before the problem i had removed the annoying "welcome" screen on WINDOWS XP. Obviously it was the new boot up sequence that was causing the TFT to hang up.... i reinstated the original welcome screen and after about a week and approx 20-30 boot-ups the TFT problem is non existant.
Hopefully this was the problem... and also hopefully query closed... I thank all who offered constructive advice . Excellent forum . bye.
