I was working on my PC when the video went out. I wasn't using any graphic intense programs, I was in Visual Stuido.NET. I gave the system the one-finger-salute to power it down. After I tried to reboot the PC, the fans were on full-blast, but no video, and no beeps. The fans never change speed as they usually do once the power has been on for 5 seconds or so.
I have since removed all components and reseated memory and CPU. I even replaced the PSU with new without any success. My latest troubleshooting session had me retracing my steps and I found the only time I was able to get the system to beep was when I removed all the RAM. I received 3 long beeps then, which went away once I replaced the RAM.
All I can think of is a MB or CPU failure. This is a fairly new system and Sony wants about $300 to look at it. Brief description below:
Intel p4 3.2 GHz
512 Mb RAM PC3200
Any help is greatly appreciated!
