My PC sometime unable to boot and stuck at POST screen like this since end of December 2011. i tried remove all USB devices, remove front panel USB port still not solve the problem.

sometimes i can boot and use normally for 5minutes or more but suddenly it will auto restart and stuck at POST screen..
i must power off and start again

Spec: ASUS M4A88T-M/USB3
AMD Phenom 2 550BE
2X2GB DDR3
1TB samsung F3
550watt CM PSU
Bios Latest 0703

action taken so far:
1- remove all USB devices (mouse, USB modem, USB speaker, USB internal memory card reader,
2- flash to previous bios
3- change Power Supply
4- disable USB legacy in bios
5- try different ram and ram slot

thanks!

erm, i think it's your motherboard problem0z..

Need to rma? Bought on april or june last year cant remember.
If want to rma at asus centre, i need to bring all item or just bring board only? How about box?

I RMAed my asus board through shop with just board and receipt, not sure if you can RMA directly to ASUS...

Bought from thundermatch. I know asus centre. Maybe in 1 or 2 weeks time still gila like this, i will try to rma it

Yup...xperlu pening2...RMA it since u have warranty
Is it possible bad hdd related? Coz your case similar to my brother's lappy...stuck at post screen and after changed new hdd all back to normal

HDD? but it stuck at USB controller...

guess mainboard faulty already.

Suspect it is the motherboard already
Go and RMA

I wonder have u actually play around with the mobo's jumper before.
Whether or not i suggest removing the usb jumpers that are connected to ur front panel.
Try if it helps.
The mobo jumpers looks like lego by the way lol.. Some usb jumpers are imprinted with USB+1 and USB-1. remove those.

nothing done to the mobo before it happened!...

fron panel already remove...

if the above method doesnt works and like what others suggested flashing firmware, i suggest u can try look for Zhen^wei.
PM him. I believe he does rma service even for out of warranty. Though u'll have to check with him the price to repair out of warranty mobo.

On keyboard,.got blink LED or not ? Count how many blink.

normally, if normal boot, all 3 keyboard led wil blink once at post screen and one more at loading windows

but when this happened, keybod led turn off....
