Win XP; system starts, nothng displays


Grumble

I have recently formatted and reinstalled Windows XP so it should be pretty clean. I am using PC Tools AntiVirus and scanned it and nothing was detected. I also installed and used Tweak CoH. The only thing I use the computer for is playing CoH and general internet stuff (no pr0n sites) and don't download a lot of programs. Prior to the recent format, the AV program detected Conficker but I'm pretty sure it wasn't present after the format as I did a full scan after downloading and again after installing each program, updates and drivers.

Now, the system starts but the monitor goes into Power Save mode and displays nothing at all. I have a Sony Vaio Micro PC connected to the monitor with analog and seems fine. This happened once about a week ago but I just restarted the system and it seemed to work fine after that. Yesterday it happened again but now I can't get it to display anything.

On PC: PNY nVidia GeForce 7900GT (overclocked from the factory) using a DVI-I cable. I have checked nVidia site and PNY site but can't find anything to help with troubleshooting the problem. Can anyone suggest a tech site that might be useful? Warranties/customer support has expired on everything so manufacturers are not helping.

Hiya.

Without knowing more about your system I would start here:

1) do you hear the regular beeps associated with the POST test when you start the PC?
2) do you see any of the startup text on the screen before it goes black?
3) does your system have an onboard video processer as well as this nVidia card?
4) if so, can you try starting the computer with the monitor plugged into the onboard video? (Then install the nVidia drivers following the manufacturers instructions)
5) is your video card seated properly in the motherboard? does the cooling fan on the video card spin? is the power cable connected if it has one?


(Please remember to unplug your computer before opening the case or working inside!)

Good luck.

Try this.

1)Open case with the power cable unplugged.

2) Look for a battery on the motherboard, the kind you see in wristwatches and some toys

3) remove battery using this guide http://www.computerhope.com/issues/ch000239.htm
Not the best guide, but it says enough.

Once the battery is no longer in its cradle, plug the power back in and turn the pc on. The PC will start with factory defaults.
