ASUS G73JH - CPU Overclocking - Black Screen?

Hey,

I recently donated in order to use SetFSB and had been testing the overclocking limits of my ASUS G73JH this afternoon.

The CPU for my G73JH is the i7-740QM (1.73 GHz stock) running Windows 7 32-bit

I had been testing my PC by overclocking with SetFSB, but taking precautions such as using RW Everything to unlock my fan speed to max RPM.
As I was testing with SetFSB I had found my crash point (ie. BSOD) at around 175-180 (via Slider) which is something like 155-160 FSB (MHz). Specifically, my laptop could run stable from anywhere between 170-179 Slider (ie. ~150-155 FSB).

So, I decided to do some more tests in this neighborhood of 175-180 Slider in SetFSB. Specifically, I downloaded Throttlestop, and noticed the option of being able to set the multiplier (ie. force the laptop to run all four cores at the same speed) as well as the option to disable BD PROCHOT which I read causes the CPU to hang up at 933 MHz. So, I used Throttlestop to force all four cores to run at the max multiplier (13 for my CPU) as well as disabling BD PROCHOT to prevent the CPU from stalling (while monitoring my temps in HWINFO).

During this whole overclocking process I had my temps monitored in HWINFO which hovered for each of the four cores at around 40-60 degrees Celcius (which makes sense since I was not running any programs in the background intended to stress the CPU).

However, upon running Throttlestop and forcing the machine to run all 4 cores at the max multiplier (which I think for four cores is 13 for my CPU) and disabling BD PROCHOT - I noticed that I was stable up to 178 slider (160 FSB) - and as I proceeded to go on to 179 Slider - my computer crashed in to the BSOD.

I thought to myself no big deal; just like the previous tests I found the limit. As I proceeded to restart my laptop I noticed - it wouldn't boot up in to the ASUS logo - specifically, I just got a black screen and after 30 seconds of black screen the fans would spin to max speed. I can't access the BIOS screen via the "F keys" and I tried connecting the laptop to an external monitor seeing if it was the screen, and...no luck.

I think my laptop which is an ASUS G73JH-RBBX05 (I think) which has the latest BIOS and vBIOS on it - it also has a "reset" button on the bottom panel of the laptop - I haven't tried this option.
What does the reset button actually do?

I don't believe I messed up the CPU here since I wasn't overstretching the CPU by very much and I had been stable at 175 Slider, so the jump to 179 Slider I don't believe adversely affected my CPU, but I don't know - what should I do?

Thanks,

I would try and check ram sticks. Just yestrday had laptop with black screen and found that one bad ram stick was culprit.

 

You could try what @Yemon did when he encountered a similar issue on the same model laptop - see G73JH Black screen - Page 2. There's no guarantee you'll see similar results, however...
