    Hey guys, I'm currently troubleshooting a friends PC which has display issues directly after rebooting from an Avast AV update. Like so many similar issues, the pc seems to run fine (HDD spinning & LED light flashing, CPU fan spinning), Although, I've yet to hear mobo beep.
    This is what I've tried already;
    Reseating ram and graphics card. Trying another graphics card, monitor, graphics cable and PSU. After that, I tried scanning the HDD as a secondary drive in my own machine for a virus. It managed to get boot priority in my machine and it actually booted fine so I gathered from that, that it's not a software problem. I've heard people on forums talk about resetting CMOS but there seems to be issues that follow that.

    Not fully sure of his spec, only it's a Packard Bell, OS: Win Vista x64, CPU: Intel Core2 Quad. If you need more info on spec I can boot it in my machine again and get it.

    Merry Christmas :D
