no signal on monitor, the computer boots up no problem

July 3, 2012 at 04:50:10
Specs: Windows Vista
no signal on monitor, monitor works with other computers. Computer boots up well and works well on safe mode only with the same monitor.

Anything to do with my children playing video games on the computer ? if so, any way to fix via software reload/drivers or is the physical graphics card destroyed/fried ???

Looked up under Device Manager and this is what I found:
1. yellow marker on isatap and yellow marker on Consumer IR Devices
2. for both items, it says, the driver for the item (isatap/consumer IR Devices) cannot be loaded.
3. when searched the net to look for the respective drivers, the computer says, it HAS latest drivers already...!!!
4. the locations for items : isatap and Consumer IR Devices are:
a. isatap : windows\system32\DRIVERS\tunnel.sys
b. Consumer IR Devices: windows\system32\DRIVERS\circlass.sys

appreciate your solutions.

Sounds like they have messed with the resolution. Start the computer in VGA mode (one of the F8 options) and then change it to the correct resolution.

Your video card must be working or it wouldn't display in safe mode. The other driver messages have nothing to do with your display; if everything else is working OK then I wouldn't worry about them.

You can not change the resolution in safe mode. If it were only a resolution problem wouldn't something still show up on the monitor? Wouldn't you still get the windows logo at startup? With this problem we don't get that far. It all starts up up to that process and then stops. No logo screen or anything, just a black screen. Sometimes the windows startup repair works and sometimes it doesn't. Very frustrating.
