Few problems lately... I did alot of diagnostics and methods and apparently it's happening somewhat random. Symptons Boot problems - Whenever I press the power button, with the AC and Battery and the X9000 OCed to 3.4GHz at startup, the 5 LEDs at the right corner light up. Then in less than 3 seconds, the rest of the indicators turned off except the power indicator - and then, it stalls there. Fortunately the Blu-Ray drive is working and "whirring" and can detract when I press the eject button. And sometimes, with a little bit of luck, it boots up successfully (The LEDs, backlit keyboard lights, wing lights) by itself after pressing the power button -and waiting- for a few minutes. And sometimes, it does a frequent freeze after startup. After loading to the desktop, it freezes - and I had to do a force shutdown. It'll be lucky if it doesn't. I did a Windows repair. Still the same. What gives? Things I did beforehand This happens a few times already. I did the usual; I had to remove the battery, AC, and even the RAM sticks, hold the power button for 20 seconds to clear off any static residue in the capacitors - and randomly sometimes it boots, sometimes it doesn't. I've also reset my OC speeds to 2.8GHz stock and tried running on battery. It still doesn't boot. Both on battery and on AC. LEDs comes on, then off. I've even reseated the 2x4GB RAM sticks and ran memtest86, it was completely errorless. I even changed to a 2x2GB kit and it was the same. Ran the inbuilt Dell hardware diagnostics test - all components were all up and running steadily. Viruses? No. Updated, scanned, and rescanned with three different softwares - Clean. It is still happening as of today. Currently, as of writing this thread. I am using the M1730 right now and it is running stable. I don't dare to do a complete restart or a shutdown else it might happen all over again. Gaming performance is excellent. Nothing wrong with the 8800Ms. My temps are like 64*C max while I game on 4 hours straight without coolers. And CPU is around in the 60s max @ 3.4GHz. Startup time is 32.56 seconds I tested just now. Do note that this problem happens randomly (yes randomly) and most of the time majority whenever I start my M1730. Conclusion and suspicion I am suspecting of a bad motherboard from my experience. What'd you guys think it would be?
