Issue: BIOS not reaching POST.

Backstory: Several days ago my slave HD started to lock up the OS with any related programs running from that disk. In an attempt to fix it, I used Hiren's Boot CD and tried to have the HD ignore bad sectors. In the midst of trying this and that, my USB drive in which I was booting from, started appearing twice in the boot menu when pressing (F11?), in addition when posting it was displaying 99, B2, A2 slow enough to where I could see them instead of a rapid number display, at times appearing to hang at B2 and or A2.

Second weird symptom: I noticed was in the BIOS in the Boot Manager, I saw two extra instances of my primary HD (SSD) for a total of 3. I gave one a higher priority, saved then the computer restarted. This is the were I'm currently at, it displays a black screen.

After pressing the Power button, I can feel the fan kick on, the only indication I have of anything to go with is the LED light on the exterior frame, lights the HDD LED for 3 seconds then cuts off.

I've tried so far:

  • Resetting the ECU - Pull battery out, unplug PSU, hold power button down for 30-60 seconds, plug PSU back in, attempt to boot, power off, insert battery back in.

  • Resetting the CMOS - Unplug CMOS battery wire from the motherboard, wait 3 seconds, plug in, attempt to boot, unplug CMOS battery for 30 seconds to 5 minutes.

  • Remove GPU and RAM stick - Removed NVIDIA GPU, and the 12GB RAM stick, attempt to reboot.

I haven't had any issue with my stock cooling fan, and I do not have anything over clocked.

Currently I have the battery out of the laptop, and the CMOS battery unplugged from the motherboard, will attempt to see what happens after 12-18 hours.

  • Please provide a BIOS brand and model. That helps with the POST codes.

    Also try to plug off anything you don't really need (including HDDs) and boot from USB. See if that gets you past the POST process. I had a faulty HDD once, locking everything up in POST. Also: give your POST some minutes to get past timeouts.

  • Currently - created an ISO with proper rom, dos file and compiled into ISO. Mounted to USB as a floppy, inserted into USB 2.0 port, held ctrl-home; power on; released and pressed ctrl-home. Only difference i can tell now, is the fan is pushing out hot air, so maybe the CPU is actually doing some crunching?

  • I'm not getting any video feed, it seems like after it runs for awhile, it doesn't want to power off as quickly compared to if i boot it up for less than a minute, which allows a rapid power off.

Reset to default

If there are multiple RAM slots, try using another slot. Also, try another stick of ram, as this sounds like a memory failure
