Hello, I have had this issue for a couple months now and I still cannot figure out the cause. I believe it to be hardware related but cannot get error returns from any program I've tested with, so is it software...?
I can play games that run direct x in full screen and never see an issue, never encounter a crash or BSoD, never see artifacts.
If I browse the net I can usually create the issue over some time, using a program such as premiere pro usually causes the issue and BSoD within 20-30 mins especially when rendering. If using vmware machines I can make the issue happen after some time as well. If I continue browsing the net when the issues begin to happen my browser will start to crash for no apparent reason as well. Windows Explorer will also crash randomly once it gets bad enough.
After I began to encounter issues I took the laptop apart and cleaned it out very well, how ever there was very little dust inside it and no vents were even partially clogged. I did do a re paste about 3 weeks ago both cpu and gpu.
Here is system specs:
ASUS G73JH-X2 Laptop
CPU i7-720QM Clarksfield
16GB 4GB*4 - PC3-10600 DDR3 SDRAM - CMSO8GX3M2A1333C9
ATI Mobility Radeon HD 5870 [ASUS] - 1GB DDR5
Hard Drive - Seagate ST9500420AS - 7200 RPM
I have Installed the Latest Bios on the Motherboard, Video Card, Hard drive
I have tried doing a system restore to factory settings, a full format and clean install using a windows 7 disk and all ends up with same issues, which is why I believe it to be a hardware issue. (Sorry I did not make backups of the dump files prior to the formats)
I have ran Memtest86 for over 3 hours, 3 full cycles. Prime95 for 2+ hours. Many hours of other various test programs such as BurnInTest. None have ever failed or returned an error message.
I have also enabled a full dump on BSoD following directions from the sticky, hopefully next time that happens I can supply that as well.
