My problem is as follows:
When I start it up I sometimes gets the black screen and nothing more, and sometimes it starts perfectly. Today it has been almost a week since I managed to start it up. It started out with a black screen two weeks ago and has gradually moved down to complete darkness as of today. It first seemed like if let it rest for 5 to 6 hours it would boot up normally, but that has changed to the worse too.
What I have done so far, one step at a time:
I replaced the CMOS battery with a fresh one to make sure the BIOS had enough power. I replaced the power supply with a new 450w to make sure the whole system had enough power. I replaced the the Radeon card with a GForce2 card to test if the video card was ok. I have disconnected my DVDplayer/writer. I have tried to disconnect my harddrives, one at a time, nothing happens. I also took the memory sticks and checked the connectors but nothing strange there.
I am pretty much going nuts over this machine. To say the least.
I deeply appreciate all assistance to solve this problem.
