About 2 weeks ago i was playing Warcraft and the screen went black, i was able to hit the windows key and return to the desktop and click on the game and continue. Over the last 2 weeks this has got worse to the point that it would happen whilst on the desktop, if i left it, it would flick back on and then off. Now when i start the computer i can see it loading but then goes black at the point where you would log in. Its not as black as if the monitor was off and there is still power going into it. Tried so far; Opening machine and making sure the graphics card (Nvidia 6800GS) is embedded correctly. Ensured all wires are sucurely in. Hooking the monitor up to a laptop (Still experienced the same problem) I can start the machine in Safe mode and get to the desktop that way, and also in VGA mode...in each ive tried to increase the resolution by 1 incriment and when i click apply it goes off. So, it looks like it is struggling to display other than at the bare resolution. Monitor - Acer AL1916W (18mths old) Pentium P4 HT 1024mb Ram XP Home If i can supply any other information please let me know...any ideas on what is causing this and/or how i can resolve this issue would be greatly appreciated. Thanks in advance.
