OK, this is a strange one...
Shuttle SK41 motherboard with on-board graphics, plus an old Radeon 8500 AGP card (64mb I think). The PC is used for basic kids internet, hotmail and watching DVDs. Has been working just fine for ages. I recently swapped out the desktop athlon 2400 for a mobile 2500. Cooler, quieter etc. Just got a new HD1080 TV in the living room and it is connected to that, but had a post last week about it not managing 1080 from the DVI to HDMI lead (720 is fine). I mention it again now simply as it might be related... The PC shut down as normal and refused to come on again. Stripped it right back to Power + Motherboard + either/both of my 2 sticks of DDR + CPU. With on-board graphics or with the AGP 8500 card the PC Posts just fine. no problems reports, but when I press Del for the BIOS, or press f1 to continue to a boot screen, the screen goes blank and doesn't come back. Machine sometimes responds to ctrl-alt-del, so its not dead. I've tried both processors I've swapped the ram sticks over and tried them each on their own I've tried with on-board GPU only. With AGP, but using on-board GPU and through the AGP card. I've reset the bios I've removed the CMOS battery and started it up Nothing makes any difference - same results every time - no video signal after a healthy post. I have not yet crawled round the back to disconnect the cables to try it on my monitor upstairs. Any ideas before I try this? |

It could be a bad power supply they are *usually* either good or bad... but I've seen a few that would allow the machine to post but do little else |

It sounds like you are saying that you are getting the text display, from post, while the card is operating in the default VGA mode. The description you provide seems to be saying that your HD TV is providing that from an HDMI input, and with it set to display at 720p. Is this correct? Now while still in VGA mode you lose the display when going to the BIOS screen or the boot options screen? You talk of an on board "GPU" and making changes in your use of that and an AGP card. How are you doing this without access to your BIOS settings? MB Jumpers? It would be of some help if you would provide the make and model of your "new HD 1080 TV", that you are trying to use as a monitor. Could you tell us if you still have these problems when using a PC monitor? Luck; Ken |

The description you provide seems to be saying that your HD TV is providing that from an HDMI input, and with it set to display at 720p. Is this correct? Sorry - a rushed post from me. I'm using a VGA cable to test this at present. It is connected to the TV right now, which can handle up to 1300x720 resolution. Until the failure, I could see the post information, boot screen, complete XP loading screens and then XP desktop. I included the information about not getting the 1080 signal over the DVI-HDMI cable just in case it was relevant. I have not been testing using the HDMI cable. Now while still in VGA mode you lose the display when going to the BIOS screen or the boot options screen? This is correct. You talk of an on board "GPU" and making changes in your use of that and an AGP card. How are you doing this without access to your BIOS settings? MB Jumpers? I can't get into the BIOS settings, but have reset the BIOS to defaults using a jumper. I assume the on-board GPU is the default. When I connect the VGA cable to the onboard connector the PC uses it. When I connect the VGA cable to the AGP card, the PC seems to switch to it automatically. I can't get to any settings to see what is default/auto etc. It would be of some help if you would provide the make and model of your "new HD 1080 TV", that you are trying to use as a monitor. Could you tell us if you still have these problems when using a PC monitor? Yes this would have been handy! Its a new Toshiba Regza 40". Full HD 1080p. Manual lists the resolutions accepted and over the VGA cable it can handle just about any resolution up to 1360x768. I will test the computer on a normal monitor as soon as I get a chance.

Luck; Ken OK, until we can rule out the video interface as a source of the problem, (by trying it on a normal monitor) there are a few other things to rule out. The first I would normally advise would be trying it with all USB devices disconnected, then with no hard drives connected (a bad hard drive can throw in unexpected problems during post as well as boot), but it appears that you already tried that. I bring it up again just in case you missed something the first time. The "Shuttle", being a proprietary system, may have "features" that don't follow the normal practices for PCs in general. I can't think of anything that would blank the screen or crash the video display when going from a good display of the post data, to the display of the BIOS screen or Boot screen. There should be no change in display mode. The one logical potential culprit might be the keyboard. You mentioned that the "machine 'sometimes' responds" to a keyboard input, you could try a different keyboard and try changing from PS2 to USB or vis versa. Luck; Ken |

Either the cable I have downstairs has magically broken, or the TV is not working as a monitor properly... At least the PC is OK! |
