[Solved] PC doesn't boot. P8P67 Mobo shows error LEDs lit. What to do? :(

On switching on my PC, I found that it is not going beyond the "checking for disks..." screen (can't remember properly, but I know it's followed by a message saying "Maxwell controller etc etc which didn't appear this time)
The screen froze or never moved beyond this point.
On checking my PC cabinet, everything seems to be working fine. But a red LED was lit. On checking the "manual" it happened to be the BOOT_DEVICE_LED
Motherboard is an Asus P8P67 Pro

I waited for a couple of minutes and then restarted my PC. It took a few seconds to restart, which I felt more than normal. But now, nothing appears on the monitor. There is absolutely no video input. Also the LED that was lit before is off this time. Now a new LED is lit which is the DRAM_LED at the top right corner. The remaining CPU_LED, VGA_LED and the BOOT_DEVICE_LED are not lit.

In short sequence of events.

Switched PC on > No boot > BOOT_DEVICE_LED lit indicating error > Restarted PC > No video to monitor > DRAM_LED lit , error (no other LEDs lit) > No progress for 10mins

Help! :(

BMG ftw!!
Problem is with SATA controller.
You may try to:
1. Clear CMOS.
2. MemOK.
3. Restart.

If nothing happens, then follow the same sequence by plugging out all SATA cables, and then add only HDD.

I have completely turned off the PC and disconnected it from the UPS.

Will Pressing the memOK button work now or should I connect it to the power socket and do it?

Thanks for your responses

Computer turned off and connected to the power socket with power flowing into the motherboard. :)

No. Switch on UPS but not the PC.

Ok I checked online. I pressed the MemOK button till the PC powered up.
It started with the DRAM LEDs flashing but soon powered down.
It restarted itself again and now it is back to how I had described earlier. DRAM led perpetually on and the CPU fan speed increasing and decreasing on its own. Now the fan speed is pretty much stable.

What to do? :|

hmm.

Try shifting the RAM to another slot. Plus, a CMOS reset like d6bmg had suggested.

Thanks for that ico. I had the manual in hand but was stuck at the 3 switches at 2.2.5 section

Still the same. No improvement. I will try changing the RAM into a different slot.

Thanks a lot guys.

I will have to wait for another half hour to do that :| Hope this goes well.

If nothing helps out. Next step would be to get a DDR3 RAM stick from someone and try it out. Plus, also try your RAm stick in someone else's computer.

:D :D :D

It's working.

Solution: Remove the RAM stick and put it back :oops:

Thanks ico and d6bmg for your help.

Congrats!! ;)
Possible reason: problem with BIOS flash memory which is solved via reseting bios+ removing RAM modules.
