Suspected Laptop overheating problem

[Glendor]

I have an HP DV7-1245DX (Specs: http://www.cnet.com/products/hp-pavi...-1245dx/specs/ ) that I suspect is overheating and crashing. It worked perfectly for WoW, Netflix, Web, and word processing for a few years, but after I let my wife use it, and she stopped using the elevated cooling pad, it began crashing. I took it apart and cleaned the fan & heatsink and put arctic silver on the chips, but it is still crashing when the temps begin to climb above 68c. I also reloaded the OS on a Seagate Momentus XT 250gb drive. It will boot and idle for hours with temps only in the mid 50's, but when I try to game on it (World of Warcraft) it will BSOD.
A mobo replacement would be over $100 and the battery is shot from sitting fully charged for too long so needs replacement too, so I can't see spending $150 as a wise investment on the laptop.

It was suggested that the GPU may need reballing, but is there anything else I can do to test things before I resort to that or selling as parts?

Any suggestions would be appreciated.

My laptop did this and when I inspected the memory I was as angry as I was laughing and I was so pissed off! My memory got so hot that it was slowly bending from the heat.

So yeah inspect your memory and make sure it is not bent in anyway.

I have worked with a similar model before (it was a little newer than this one, but it had a Turion X2 and the chassis are identical) and I remember that they do get quite hot, even for a laptop.

The crashing doesn't necessarily mean that it is overheating though. I would recommend running something like WhoCrashed http://www.resplendence.com/downloads and see what the minidump files are pointing to, assuming it had time to write some.

I don't believe the RAM is getting too hot, and they certanly looked normal when I dissassembled the laptop for cleaning. I suppose I could test each bank separately, and might even have an extra SODIMM I can test with.

I'll give that a try.

I have a dv7-1769wm or something like that and it too has heating problems. I play it with the top cover off and it still gets hot with a pad under it. I've tried re applying thermal paste and changing the fan out. My only remedy was too power off the computer daily and blow out with compressed air and that didn't even last long. I used a cooling laptop stand as well. Just purchased a desktop
Computer to replace it. Tired of playing wow on low.

I ended up hosing the systemboard when I tried to reflow the GPU solder points. It won't boot now. I'm going to sell it for parts and look for a replacement during Black Friday
