Hey guys. I have been having some problems since January of this year and they are yet to be resolved.
Here's a list of problems i am having -
1) System randomly hangs at bootup(at Loading Windows Screen, before POST, during POST)
2) System hangs when i use my front panel USB slots.
3) If i hard reset or reset cleanly (from windows) it hangs either at POST, before it or at the Windows loading screen. Hard resetting after that doesn't work. Everything else works (CPU works, fans work, etc.) but no signal to the monitor (remains blank). I have to shut down using the power button, turn off the power and turn everything back on to get the system to boot in to windows.
ASUS service center in my city couldn't reproduce these problems at their site so they passed the motherboard off as OK.
Here is a long list of what i have tried
1) ran prime95, Intel Burn Test to check if CPU is working fine. It is.
2) got a new 750W power supply thinking maybe the system was underpowered. waste of $90 because the problem still persists
3) ran memtest86, memtest86+, windows 7 memory diagnostic (extended tests). No errors.
4) took the whole system apart keeping only the CPU and 1 stick of 2GB ram in. It would boot after being "Powered ON". But on restarting it would hang at one of the places mentioned above. This implicitly rules out my hard disk, graphics card, WLAN card and my DVD Burner, if i am not wrong.
Tested both the stick of RAM (2GB each) on each of the slots i normally use. Same problems as mentioned above.
5) Enabling Unleashing mode causes problems (Unleashing mode failed error at POST), so running on the stock 2 cores. (Unleashing mode used to work fine before).
6) Removed USB cable connecting the front ports thinking that was the problem, but to no avail.
7) Updated all the damn drivers i could think of including DVD Burner and HDD Firmwares. (BIOS latest, Nvidia Drivers latest, WLAN card drivers latest), but it still hangs.
8) Cleaned all hardware.
9) added 2 more fans thinking system was overheating. one pointed directly at the northbridge cooler which tends to run the hottest on the motherboard and one directly below the graphics card, the second thing to run at comparitively high temps. Put some Cooler Master Fusion 400 thermal goo on the processor too. Left the cabinet open to ensure proper airflow.
10) ran verifier to verify if any drivers were causing the windows to stop from loading. Windows booted up fine.
11) Cleared RTC, tried removing CMOS battery. Everything on stock settings right now.
Now after all this i am obviously led to believe that the motherboard is at fault. But how does the ASUS service center not get these problems ? It's a hell lot of work to do just to get the system to work. Can anyone help ? Any input appreciated.
