Windows XP won't load
i've had a problem with my other computer for some time now and have tried many things but to no avail, maybe someone can help.
Its an old P3 dell with 256 MB RAM.
When i try to load windows by turning it on, it first does the whole bios thing, checks the ram etc, but no sign of windows loading, it just goes from the bios stuff to a blank, black screen with a horizontal flashing line on the very top left of the screen.
Now i know it detects the drive as it shows up during the first loading.
I know the hard-drive and windows installation on it work as they work on my other computer.
So far ive tried, different hard-drives, re-installing XP many times, changing graphics cards, trying with different ram sticks, taking out the sound card., but im still in the same position.
Could it be the motherboard or bios or something?
Any help is greatly appreciated.
