First faced problem starting it up. Followed in another thread http://forum.giga-byte.co.uk/index.php/topic,2685.0.html

Got it solved. Was working for 2 days ok with win 7 ultimate. I was not happy with the wiring layout and the case fan controller which is inbuilt in case LCD and decided to set it right. Got it done the way i wanted and started it. And all hell broke loose. First the bios post screen went through and the next command line saying loading operating system but got stuck in the next command which said load from CD/DVD (y/n). I tried entering the bios setup; after a couple of hiccups got the blue screen but got stuck there.......... Next i tried putting the win 7 OS cd and tried starting it but came to the first problem again......... All in all the keyboard was not responding.......... I tried to change the boot sequence but the screen came grayed out; no option was accessible..........

If somebody can throw light on this.......... i would be much obliged!!!!!!!!!!

Using that PSU that came with the case? Theirs your problem.

Either that or you have displaced a wire when you were rewiring it.

[Peteruk]

Or broken something when moving suff around, Or you moved SATA cables from blue to white ports....

I removed all wiring from the psu and kept it only for the mobo, cpu, dvd and hdd. It just hangs in the bios post screen and the keyboard is killed. The lights in keyboard come on for a second and then vanishes........... the same450 watts psu ran all components perfectly before this problem. i reverted to the original layout which worked but the same problem............

[ABully]

nope the sata is in the white port.......... the cpu fan is spinning the phae LED is on.........even the psu fan is spinning.........

As Peteruk said in his first response it is most probably the PSU especially if it came with the case.

I have encountered this problem before and the only solution I found was to replace the PSU with a decent one.

Only other thing to check is that the stock cooler which I take it you still have fitted is firmly fixed down at all four corners.

It was working fine till i reconnected the wires............ the boot is not moving past the bios post............ and the keyboard is killed.........

checked........... i didnt touch the cooler nor the cpu......... i just reconnected the wires from the case lcd to the case fans......... the case fans were earlier connected to the psu directly.......... but you guys are missing the point.......... now the system is almost bare with no extra power connection to anything............. and the keyboard is getting killed at bios post and hangs there.............

I know where you're coming from but as I said I have had this happen to me before.

In fact the system would get all the way into Windows on occasions and then just freeze. This was really frustrating as I had built the machine for a friend and he took a lot of convincing that it was a faulty PSU. However, after  I replaced the PSU with a good spare that I had he has had no further problems.

[ABully]

one other thing is the system was shocking with static electricity badly when i was redoing the fan cable.......... it is now non existent.......... could this be a sign???

[Dark Mantis]

Force majeure!

Thanks guys.......... heading to shop right now......... they have coolermaster 750 watts (overkill) and thermaltake 500 watts (ok).........

Will also check this out if they have  http://www.newegg.com/Product/Product.aspx?Item=N82E16817171046

Personally I wouldn't put the cheapo Coolermaster one in an old machine
