I unfortunately have a hp dv6000 series notebook. It would only load maybe 1 outa every 20 restarts, this was related to the defective nvidia gpu that would overheat and burn out. HP's extended warenty replaced the mobo once. About 6 months later video wouldnt appear, but i would get poor output to a external moniter, as long as i did not attempt to change any video settings, if i did it would black out and die. Talked to HP they said its my problem now because even though it was defective, it was past the extended warentee, but they generously offered to replace their defective motherboard again for the price of $277. I opted to buy a refurbished one from hong kong for $70, which claimed to have fixed the issue. 3 weeks later, and 3 hours of motherboard replacement, and i had a working laptop again... for about 6 days, then it died again, this time with the one long beep and 2 short beeps post code and no display. The ebay seller said to send it back and they'd replace it. So $30 in shipping and 5 weeks later i got another motherboard. Since i knew what i was doing this time the install took maybe 1.5 hours. Working laptop, upgraded the bios, and the gpu and first cpu core were running around 110 degrees C, so I bought a notebook cooling unit, dropped both numbers to around 90. 3 days of light use later it starts beeping at me with a dead display again. Coming back to it the next day deciding whether or not to sell it for parts it booted up fine. I'm at a loss, its obviously showing signs of failing again, but should I just use it 'till it dies completely, or tear it out and pay another $30 if the guy will even replace it, and wait another 3 weeks, Or buy some superpowered cooling unit to replace my cheap plastic one? I've even been using the silver thermal compound instead of ceramic, though i doubt it would make a big deal. The only thing that i could think that might be why these new ones don't work for me, other than just the poor quality of the original product, is that its a slightly different mobo than my original, which had a geforce go 6800 and the new one has a 7200, so maybe the shells had different cooling units? but my model is listed under the supported models on the ebay sellers list.
