Hello! smart members of Asrock forum. Smile

With your guidance and help I am sure I will be able to solve this problem.

System Configuration:

Motherboard: Asrock Z77 Extreme 4

CPU: Intel 3.4 GHz LGA 1155 Core i5 3570K Processor

RAM: Corsair Vengeance DDR3 8 GB

HDD: Seagate Barracuda 2 TB Desktop Internal Hard Drive

For the last three days, the system does not pass the POST stage. It gives a 9A error(USB Initialization is started). I am not able to enter BIOS even. The LED screen remain switched off.

If I start the system after 1 hour(Clear CMOS, unplug the power cord completely), it successfully pass the POST stage and windows loads, however even the windows got corrupted somehow and gets stuck at recovery options. The Keyboard hangs in recovery stage and cannot select any option.

After this ordeal, I have to restart the system and then again it gives 9A error. I have googled thoroughly for any solution and tried them all(I guess), still no good news. Ouch

Friends, this is frustrating. I request you to provide some ideas to solve this.

Should you require any detail, please ask me.

9A relates to memory. That could lead to HDD corruption too.

Is your Corsair 8GB two 4GB sticks or a single 8GB stick? If it's two sticks I'd say it's time to play swaparoonie using each individual stick and hope you find the one that's gone bad. Assuming this relates to a dead or dying stick.
