But given so few details I can't tell which issue is affecting this PC.
Why do you suspect the RAM? Has it failed some test?
I finally got rid of XP Pro x64; and purchased Windows 7!
I performed a "Disk Wipe" with "The Ultimate Boot CD"; which contained a Utility called: "Darik's Boot and Nuke 2.2.6 (Beta), did the task for me.
Here's the problem: When I start the Installation for Win 7 the 1st round is fine and the Computer ReStarts, and it starts to "Start Services",and some Registry Entries...THE SCREEN IMMEDIATELY GOES "BLACK WITH THE DOS PROMPT FLICKERING"? I tried letting it stay there for a while in HOPES that the Continuation of the Installation would continue, but NO LUCK?
Anyone know what's causing this? I've heard it could be a problem with RAM Memory? Not Sure!
