HP dv6 Random 0x124 BSOD While Using Games, Videos, and Internet
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 3 years now. It was running great until about August or September last year when I would occasionally get a blue screen when playing Fallout New Vegas, which I had been playing on and off since Christmas 2010. 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. Then I started having it also occasionally blue screen when 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. It is not being overclocked, I donít even know how to overclock things even if I wanted to. Also it is not a RAID drive as it only has one drive.
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. I replaced the hard drive thinking it could be an issue, and no go there. Then figuring it was a thermal issue I got a friend and we ripped the notebook open and replaced the thermal paste. The fan seems fine and since doing it on the whole it has run quite a bit cooler since the CPU paste was pretty stiff. That seemed to work for about two to three weeks and bam again another blue screen, which is always the same regarding hal.dll and ntoskrnl.exe. I know it is a 0x124 error and as such different to diagnose the issue since it is likely hardware related but I donít know what else to try to test figure out the problem. Any advice on how else I can figure out what is wrong would be welcome since I cannot afford to replace this machine right now.
