    Bummer

    I stumbled upon this post. The board here has a wealth of info about troubleshooting problems (Guides & solved issues). Some of my posts show my interest in recovering dead machines.

    Graphic cards (video) and power supply units (psu) are high on the suspect list.

    Check the cable and connectors for the monitor. Is the video intergrated into the motherboard? Does the monitor work in another computer? Is this no longer a problem?

    Is the problem now reduced to 'cannot boot into safe mode nor normal' ? Is it a rolling boot or a hard shutdown?

    See ya.

    Thanks for your reply

    I took the Graphics card to a PC repair store and got it checked, and it is the card. I have a Medion PC with a Radeon 9800 XXL card this is the second card in 3 yrs. What could be the problem? I thought Radeon was a good card.
    Now what card do i replace it with? Can i put any card in?

    heat & transients

    Serious gamers post in this forum quite often. I think I have detected that driving machines to the edge is quite exciting. Most take precautions against heat by installing more and/or larger fans. Placement of the card (if pci) is also considered, as well as, going to round cables versus the standard ribbon cables for the drives with the understanding it makes for better air movement.

    Also, postings in several forums are fussy about power supply units (psu's). If the graphics card is receiving inadequate power, it can be damaged. Inferior psu's also generate voltage transients which are harmful to all electronics.

    One thread I participated in, solved a problem with the graphics card by blowing away the accumulated crud. I assume precautions were followed to avoid esd (electostatic discharge).

    Other threads cover overclocking and the potential to damage memory and cpu. Others should be able to contribute here to advise you if graphics cards can be tweaked to avoid undue stress.

    No, it is not a PCI card it is an AGP card can i still put any card in, and what would anyone recommend? I am not a big gamer.

    known conditions

    Based on posted info, your computer supports AGP 4x or 8x. Your defunct Radeon 9800 xxl used a direct connection to the power supply and it had an on-board fan. Most computers support PCI graphics cards, as well. Any card needs to fit the space inside your computer.

    All PCI slots are not considered equal. Documentation for the motherboard may cover this aspect. In general, closest to the agp slot usually works best.

    A familiar catchphrase often posted here: RTFM - meaning that documentation supplied with your computer should be consulted.

    Remember, sometimes graphics card failures cause failures of the power supply unit that do not give convincing symptoms. With a new graphics card you advance to the next step and, hopefully it means you are in the clear - up & running.

    Good luck.

    hallmark signs of a failing PSU.
