GA-H57M-USB3 will not boot up

[yashoshah]

I already connected hard drive outside the computer case while mobo on the cardboard but the same problem encountered. System boots when the windows logo pops up and goes in loop of OS loading and rebooting.

So i don't think that there is short in computer case, as the similar problem is outside the computer case.

Well, i would definitely buy a buzzer but now what else remains to be done??

I removed the motherboard from the chasis but with Processor/heatsink/fan/one correct memory stick on it, laid it on cardboard, then added the keyboard and connected PSU. Board booted normally, i also added display- everything was just fine- no beeps - though a message was there for connecting hard disk for booting.

Well if everthing was running fine and then you connected the hard drive up and it started looping it must be a problem with the hard drive. Maybe it is faulty. Is it a SATA HDD? What make/model and age?

Everything is fine now. Thanks a lot for your kind help, I learned a lot during this problem.

Actually the problem was not there as such-- Windows was not loading from pre-formatted HDD's  which i used to use on old computer with totally different configuration (Intel mobo and P4 with DDR1 RAM).

I had to reinstall Win 7 and voila. -- It installed smoothly and now system is booting fine and windows running ok.

I think when one changes mobo, the fresh OS install is reqd, and due to some configuration change it may become necessary.

Though one stick of RAM showed errors, i gonna RAM the kit.

Thanks.

You are very welcome.

Definitely you should format the drive and start of with a fresh installation of the OS when you change a lot of hardware like that. I took it for granted that you had ...it wil teach me not to assume things.

Yes RMA all the memory as it is a matched kit and so needs replacing as such.

Have a good New Year.
