I've had this WinFast K7nCR18D PRO since January this year. All has been well since about 8 weeks back when occassionally the PC would fail to boot. It would -
Base Unit Green LED on
Base Unit Red LED on
CD ROM LED would flash 1-3 times and go off
My Iiyama CRT Monitor LED would go green and display a white screen.
System does NOT beep
Resetting the PC 1-6 times solves the problem. The PC WILL power up and everything works.
In the last week, I powered up and got a CMOS Checksum failed, default page loaded. I reset the CMOS and resaved my settings and it went away. For some reason though a later reset, it did power up with 100FSB rather than my set 133FSB resulting in a lesser clock speed in XP.
Is this my PSU? Or could it be my motherboard? I don't understand why it powers up sometimes and not others.
FURTHER INFORMATION -
PSU is 350 Watt peak power PSU, ATX 12V standard with AUX connection P4 (came with case and has worked with setup perfectly for 10+ months). - "Eagle power PSU" and offers 28A on the +3.3V, +35A on +5V and 16A on +12V
PSU specifications - http://www.deer-group.com/products/active/DR-B350ATX.pdf
- Getting new CMOS battery tomorrow even though existing one still provides 3.3V (tested).
- I am beginning to think this is a 'cold boot' issue. This problem only occurs in the morning when PC has been off for a while.
