Blank screen after lightening strike. Works with linux/win2k but not XP.
Posted on 2006-12-01
I'm troubleshooting a desktop computer which stoped working after a lightning strike.
XP home is installed on the computer. When trying to start it the screen goes blank imediately after post. The monitor stays on and does not show a "no signal" message, so it looks like there is still a signal from the PC. Pressing F8 to show the menu has no effect. When booting from an XP installation CD the screen goes blank after the "Setups is inspecting your computer's hardware configuration" screen.
It will start and I can enter bios setup. Booting from Xubuntu live cd works fine. MemtestX86+ finds no problem. Hitachi Drive Fitness Test find no problem. The PSU is working. I have replaced two visibly damaged caps on the motherboard. I have tried a different graphics card, PSU and CPU.
Any options besides replacing the motherboard? Also very curious why this problem affects XP only.
