HP dv6 random BSOD on games, videos, and internet browser

Hello,

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.

Your .dmp file shows a stop error of 0x124 which is a general hardware error .

A "stop 0x124" is fundamentally different to many other types of bluescreens because it stems from a hardware complaint.

Stop 0x124 minidumps contain very little practical information, and it is therefore necessary to approach the problem as a case of hardware in an unknown state of distress

Some generic advice.

If you are overclocking STOP. Return to the default settings at least for now.
If you are running a RAID update its driver.

I actually already looked at that post when I was trying to diagnose it myself. Plus the nature of the 0x124 is part of the problem. I am not overclocking, heck I don't even know how to overclock nor do I care to. There isn't a raid drive as it is a notebook and such I only 1 hard drive. I've tested the stress tested the memory and the cpu and both passed just fine. Plus a number of the crashes were under 70 degrees centigrade. So I don't know what other possible hardware problems it could be, hence why I posted here hoping that folks who know this stuff better can give me ideas to try. I would have given up and replaced the thing by now if I could afford it but I am hoping someone can help me diagnose the problem so I can hold out until I have a decent job and can buy a cheap but powerful tower.
