    Perhaps that is why it blue screened.
    Read the 0x21 dump output, and find IRQ=5 in the cause field.
    Attempting to read 0x000 is in the protected IRQ offset tables in base ram.

    Again, this is a stupid coder problem.
    More than likely a local variable overflow such as sticking a 64 bit value into a 32 bit variable, and overwriting the executing code.

The easiest way to see is to check your CPU usage while you're watching live HD. If it's super low (~3% for me) then you know your graphics card is doing most of the work.
        Hi! I am not able to test my card with live HD TV because we don't have any HD shows here yet.

        Most dvb-t channels here broadcast MPEG-4 H.264, but SD resolution.

        The total CPU usage varies between 50% and 60%. I don't know what service belongs to the dvb-t decoder, so I attach 2 screenshots of the task manager.

        Given that this is a slow computer (Athlon XP 2200+, 1GB DDR 355MHZ, ATI HD4650 AGP) and I am running Windows 7, do you think hardware acceleration is enabled?

            i doubt it. hauppauge hvr 1250-1300 series all use soft-drivers for the mpeg encoder feed. even on my modern system its roughly 10% for qam, so with hd dvb-t i would expect even more.

                Denon Mc6000 channel 1 completely non-functional
                by falcontech
                Hello
                I need your help with a non-functioning channel on this Denon controller. I noticed the problem because, with the mixing software, the channel appears completely off and none of its controls work. At the top of the channel, like the others, there's a selector switch that moves between MIDI and external audio inputs. I also tried connecting an audio source (since it's also a standalone mixer) and I got no input. The flat cable connecting this panel to the sound card is fine. I'm attaching a photo and the service manual. I hope someone can help me resolve the issue. Thanks....

                Dell E6540 laptop completely dead after dssasembly
                by max-power
                Hi, I disassemble my laptop to replace the speakers, to access them, you have to remove everything including the heat sink and fan, unscrew the motherboard, lift it up a bit to access the speaker wire.
                that was not the first time I dissasemble it, i did replace the same speaker a few year ago and I repaste it last year, so I had nothing to worry about. but when I put everything back together, its completely dead.

                After a bit of investigating, i found one pin of the status led ribbon cable that was unglued from the cable and bend touching another pin, I bend it back at his place...

                RX570 dies completely, then recovers.
                by fiveseventy
                Hello all,

                I have a Sapphire Radeon RX 570 Pulse ITX 4GB (single fan) which has started misbehaving recently.
                The card was bought used maybe 5 years ago and has worked without issue until recently.
                I have no reason to believe it has been worked on or physically damaged.


                For periods of time it will be 100% perfect.
                Perfect temperatures, no glitches or artefacts, solid FPS.
                I can game, run benchmarks, do whatever without any problem.
                I can reboot the machine as many times as I like and nothing changes

                however, most times...

                Completely dead MSI z490 tomahawk
                by pavski
                Trying to troubleshoot MSI z490 tomahawk board and would appreciate your help. The board is completely dead and shows no activity when the power button is pressed.

                I have tried to look at the Superio, the PSIN signal seems to be correct (goes from 3.3V to 0 on button press) but the voltage on PSOUT pin is quite low. I

                t is only 0.8V which seems to be incorrect but goes to 0 when the button is pressed.

                Can you please let me know if this is indeed incorrect and what else should I look at next?

                Thanks!
