I reloaded AVG 9 yesterday, and it didn't load properly. I rebooted the machine, and now it won't reboot. I get the motherboard flash up, then a quick glance of the windows XP screen, then it goes dark and it won't come back (not for hours, not at all). Tried booting from the install disk (XPSP2), but same result. Tried booting to CMOS/BIOS, and it also flashes on, but then then blinks out and also doesn't come back. Hadn't had any bad issues prior to this, been working fine. Any ideas?

As an update, the software seems to be running in the background. The screen stays back until I shut it down, till you see the "windows is shutting down" blue screen for about a hafl second.

check the monitor cables try a different monitor try a different video card

That's not the problem. Hardware seems to be working fine.

"Tried booting to CMOS/BIOS, and it also flashes on, but then then blinks out and also doesn't come back" The BIOS is unrelated to Windows or any other software. If you can't bring up the BIOS/CMOS screen, you have a hardware porblem.

"Hardware seems to be working fine. " Really? And how did you come to that conclusion given all you have written to the contrary? Hey if you didn't want advice why are you asking for it?

I say that because the screen continues to work, displaying the same images in a predictable sequence, and displaying the no-signal image when you would expect it to. Also, the hard drive seems to be running fine, and acting just as it should, except the Windows screen just doesn't come back as you would expect. The memory doesn't crash, windows continues to load, and shuts itself down after it loads up. It all seems to work exactly as it should, except between the windows XP loading screen, and the shut down screen, the screen goes black. Clearly, there's a problem, but it doesn't seem to be the hard drive function, the motherboard, the memory, the monitor, the power supply, or the CD-ROMs.
