After 13 years, can no longer recommend HP - Chronic MB problems on dv6t-7000 unheeded by HP support

Question

I couldn't find anywhere else to voice this - my dv6t-7000 is just out of warranty and thus I don't qualify for email support. I have spent the past year in a back and forth battle with HP customer support and am finally calling it quits after 13 years of exclusively buying from them and recommending them to less tech-savvy friends and family.
I ordered this laptop around July 2012, eager to check out the benefits of Seagate's new 2nd-gen hybrid drives. Laptop arrived and was blazing fast, but starting getting some STOP errors (blue screens) pretty soon. Because this was coupled with hard drive errors, I didn't bother to dig too much into the problem and instead contacted HP, who (very quickly) shipped me a service box. I send them my laptop and get it back a couple of weeks later, but can't figure out what they changed (I later found out they just reflashed the BIOS).
Sure enough, I start getting the same errors again. Contact HP a second time and they recommend a replacement hard drive. Swapped the drives out and started fresh, but within a couple of weeks, the same errors popped up on the new drive. At some point around here, I was told I was being moved up to a Tier 2 support level, which didn't seem to make a difference in how much (or little) support seemed to pay attention to my own observations of the problem. Their process came across as (1) determine if support is needed and warranted (2) ship out prepaid service box (3) let the service department start from scratch to diagnose the issue. 
I ended up sending the laptop to HP a third time, after clarifying the issue with the support reps I spoke with and giving them detailed instructions of the problems I had been observing, which seemed to point to a faulty hard drive cable or a related issue with the motherboard itself. The rep was very friendly and promised to relay this information to support before they got their hands on my laptop. Sent it in and again - no difference except a freshly installed operating system.
Before this third service call, I had freshly installed Windows 8, and if anything, the problem had gotten worse. I had run memtest with no errors on either sticks, ran SeaTools DOS with unspecified corruption errors, cleaned out the insides with compressed air, reinstalled WIndows 8 twice from scratch, ran dskchk and SFC countless times with unrepairable errors, run DISM a couple of times unsuccessfully, swapped out the CMOS battery, and was still basically experiencing a stop error every 1-2 days. I reinstalled Win8 after receiving my laptop back for the third time, and continued to have these problems. At this point I gave up trying to send it in to HP, because school was getting in the way of my ability to be without a laptop for 2 weeks at a time.
Currently, I cannot install Windows 8.1 and still experience KERNEL_DATA_INPAGE_ERROR and CRITICAL_PROCESS_DIED stop errors every 2-3 hours. I had one while writing this post, so hopefully I haven't forgotten to include anything. I don't mean to lay all of the blame on HP, but I don't like not having my input listened to or considered. It seems counterintuitive to me - this process could have taken 2 weeks to resolve instead of multiple months to fail and lose a customer in the process. 
I bought HP knowing fully well that I was paying for high-end parts and not necessarily build quality. That's never been a problem in 13 years of buying laptops and PCs from them, as well as recommending them to friends and family - we know how to take proper care of expensive technology. But I'm realizing now that when you do get a dud, HP support seems to do everything in its power not to have to replace your laptop even when it's warranted. I will use this laptop until it can no longer function (hopefully a couple of months at least) and then consider another company for the first time in a long time. On the desktop end - well, I've been meaning to build a PC for a while now.
