Hey there guys, i've been having some pretty big issues with my DV7. I do a bit of gaming on my laptop, i have a cooler for it, to prevent overheating. However, lately, it has been randomly shutting down without warning while playing games. So i downloaded a program to see the temperature it is running at. Generally it runs at about 80 Celsius which seems a bit high..Anyways, the big problem is; this morning i was playing and all the sudden it shut down. I then went to turn it back on, and it worked for a few seconds and shut down again. I then turned it back on and realized that the power button was flashing, and that was it. It then shut back down, and now when i press the power button, nothing happens. I've tried the process of removing the battery and power supply and holding down the power button - nothing. I then fiddled around with the RAM and such, the laptop now starts but the screen is still blank. The Num Lock, and CAPS lock lights flash 4 times then pause two seconds and repeat. I read that this is likely a graphics card failure, guys any help would be greatly appreciated. thanks so much
