Asrock X48TurboTwins WiFi BIOS freeze

[edepsiz]

Greetings all,

I bought this board in combination with a Visiontek HD4870, 2x2GB OCZ Intel Extreme DDR3 1600, and Intel Q9550 CPU. The system is attached to a PC
Power and Cooling 750W PSU. I assembled it last night, but unfortunately, soon after in enters BIOS it freezes up and then won't POST for a while. After 5 minutes or so, I can enter BIOS
again but it will freeze up again within 20-30 seconds. I am thinking it's some heat issue which freezes up the board and then once it cools down, I can
POST again.

Within the brief period of time before the BIOS freezes, I can see that it recognizes the memory and the CPU correctly but that's about it. Any ideas what the problem could be? Unfortunately I can't test any of the components on another board since my other system is an MSI 865PE AGP DDR board. So, I can't say for sure it's the board but if feels like it. Any helpful advice would be appreciated it. I have built three systems before using Asus and MSI board and this is the first (and possibly) last time I got a Asrock :/

Thanks

Ed, first, try clearing the CMOS. If that doesn't work, then try reseating the cpu heatsink (clean & reapply thermal goop first). Also, try testing the memory one stick at a time...mem could be defective, or a bad dimm slot.

Make sure nothing is shorting out the system (motherboard not grounded properly, etc.)

Can you try a different keyboard? I recall someone on this forum having weird issues that seemed to be power supply related, but actually ended up being a bad keyboard.

Good luck..

Thanks for the suggestions OH, I tried them all but unfortunately none of them helped. I did notice one thing about the keyboard though, the KB stays powered on even when the computer is shut down (it's a PS2 KB). For example the CAPS LOCK light will come on when I hit the switch. I have not seen this with my other systems using this KB. It's as if the board is still
supplying power to the KB even when the PSU is shut off. Maybe there's some faulty wiring?
