No Post. Athlon 500 system with SD11 MB DEAD. Was working fine before lockup.
Did reset and got a Hangup, both the power and IDE LED,s
came on and stayd on but with no post... Fans (including CPU fan) would power up.
After second power down and reset, LED,s would no longer come on,
but the fans still power up after I
push the power switch. The switch will not do a power off so I
have to turn off the main switch on the back of the power supply .
Things tried; 1. reset cmos 2. replaced cmos battery 3.reseated all cards , memory , & CPU.
4. Removed all cards and tried a known good video card and monitor. 5. unplugged all extra
fans & drives from power supply. Could flaky +5 voltage output cause this problem?
I don't have any extra power supplies but did check to make sure I at least had +5v & +12v dc,
. Would like to avoid purchasing parts
without first solving this if posible.
Could someone tell me if these symptomes most likely indicate a bad main board,
CPU , or power supply? Or am I over looking somthing here? A reply
BEFORE I break somthing would be greatly apreciated...
