P5B Checksum Error

post #1 of 19
Thread Starter 
I have just finished putting together a comp and it won't power on. I took it apart and tried to run it out of case, but still nothing.

The ASUS name on the bottom is blue, which means the mobo is getting power. We've tried to use another PSU but still no power on.

I have tried to use two power switches, and still nothing.

Suggestions?

Just tested PSU, works fine. Can only the power switch be messed up? And if it is...is there any way to fix it?

I have a P5B-Deluxe and I recently built my computer no more than 4 or 5 days ago, I had a similar issue, but my fix was just double checking the connections. After a quick change of a connection, it booted up fine and all devices were recognized instantly. So my only advice would be to double check the connections. I've known of MBs being faulty too though, so who knows. What else is your rig made out of?

Have the extra 4 pin power connected? My ASUS has the full 24 pin board connector and even the additional 4 pin beside the CPU.. I'll check your manuals and see but I'm sure they support it.

I forgot to pug in the 4pin cpu power cable when I got P5B Deluxe. I was to used to taking apart computers that didn't have that cable, so I forgot about it.

Have you reseated your CPU? Made sure it was installed just right, and checked for any bent pins in the socket?

Also, if you remove the ram, do you get any beeps?

another thing, make sure the "clr cmos" jumper is on 1-2 for not clear. most motherboards wont boot in the clear cmos position.

for some reason some manufacturs ship it like that
