So I have an HP Pavilion dv6z notebook running 64 bit Windows 7, it originally came with Vista pre-installed but I received an upgrade disc when 7 came out, that I have for about 2 1/4 years now. It was running great until about August or September when I would occasionally get a blue screen when playing Fallout New Vegas, which I had been playing on and off since Christmas 2010 when I got it. This happened once every couple of weeks. Since then slowly more programs things have been tripping the blue screen and the frequency has increased. Now a number of games, though mostly newer 3d games and minecraft, have been setting it off. As well in the few months I have also occasionally had it blue screen when I am just using a web browser or watching a video file.
The notebook is a HP Pavilion dv6z (s/n: CNF9351VRX, p/n: NT594AV), with an AMD Turion x2 Dual-Core Mobile RM-75 cpu, an ATI Mobility Radeon HD 4530 graphics card, an Atheros AR9285 802.11b/g/n WiFi Adapter, a 300 gig hard drive, 4 gigs of ram, and a blu-ray drive. I don't know what the motherboard or sound cards are.
I have been trying to troubleshoot this myself, and with the help of some friends who work in IT and electrical engineering, but at this point I have run out of ideas. I have reset to factory settings in December, though that was due to a virus creeping in and ravaging windows, so reinstalled 7 and it now has a cleaner version on, but the problem persists. I've driver
swept and reinstalled me drivers
with no luck. I have also virus, spyware, trojan, and malware scanned finding nothing. I've torture tested the CPU and it passed with flying colors. I stress tested the memory with much the same result. Yet still I keep getting this blue screen, which is always the same regarding hal.dll +12a3b and ntoskrnl.exe +18d513. I have also taken to leaving HWMonitor open when I am using my pc, baring directx programs, and I have seen multiple instances where the cpu was in the mid 60 degree cetigrade range when it blue screened. Since this has hit me 3 times in the last week (once will playing the mass effect 3 demo, once while watching a video file with no other programs open, and once while using firefox to look up information with only 2 tabs open) I am at my wits end and could really use some help.
