Abit BX133-RAID problem

[Guest]

I am having a strange problem when trying to go into the bios on the BX133-RAID board. I bought 2 for testing, and both have the same problem. The system hangs when going into the bios. I get a black screen with a blue line across the bottom of the screen. Sometimes after two to three reboots I can get in, but sometimes I have to reset the CMOS then try again and I it will work. Sometimes it happens even after I reset. I have tried flashing the latest bios, with no change. Other motherboards have had no problems. The only two things that I can think of that may be causing this are:
1- System Monitor tells me that the +5 voltage from the power supply is 5.5 v.
2- I have too many components and cards in the system and the 250 W supply cannot handle it. I would appreciate any input I can get on this.

I would suspect door number 2.

I had the same problem with my BX133, I called Abit and they said it could be case fan? Sure enough when ever I plug in my Sunon 80mm fan I can't get into BIOS. I stopped using the one of the fan headers by the CPU and have not had the problem anymore. I have both case fans running off of the other fan header using Y connector. I hope this helps.
