I have a Windows 7 64-bit desktop that has had problems with blue screens. It went about for a few months every few weeks so I never cared to investigate why. Then it started happening with increasing frequency, to the point where the computer had trouble starting. It would hang up before it would hit the Windows logo or oftentimes within ten minutes of booting up. Useless.
The first blue screen of death was
usually IRQL_NOT_LESS_OR_EQUAL.
I thought it might be the RAM (this is important for later) but I ran a memtest and it came up clean. DDR3 4x2GB sticks. Two were installed about nine months ago, the others three years ago. All four are the same.
I went the rounds with my drivers but since I have my programs on my SSD (C:\) and documents and STEAM on my D:\ drive I just went for the nuclear option. I reinstalled Windows 7 and of course, I still had problems. Now, more than ever, the computer wouldn't boot or would get stuck in an infinite booting loop at the start of things before just crapping out. I'm sure stuff like that's great on my hardware.
So in short order I purchased a new power supply for no other reason than I wanted a new one and since it wasn't the RAM I figured what the hell. Hindsight being 20/20 I have no idea why I assumed issues with the PSU. Three days later my PSU is in from Newegg, I do some housecleaning and I'm still smart enough to install a PSU correctly. The computer works for six plus hours straight.
Then I get a new blue screen that says PAGE_FAULT_IN_NONPAGED_AREA. The computer hangs up before the windows logo every time from here on out. The description I found for this is:
Faulty hardware, including RAM (system, video, or L2 cache).
SO, I'm reading up on blue screen problems even more and I'm going to start taking RAM sticks out one at a time and seeing what happens. I'll then double check that I have the PSU in right, though I don't figure how I could have got that wrong if it was running and playing nice for hours otherwise.
I won't be able to work on my computer for another twelve plus hours, but if anyone has any ideas for me I'm open. I'm really hoping it's not a problem with the motherboard. Should I be able to get Windows open I'll try and get a dump file for others to examine.
Perhaps this post will remain a monument to my ignorance as a monkey swinging tools in the general direction of a computer in hopes it'll start working. I haven't tried humping it just yet, but the day is still young. If anyone can illuminate a likely problem or point me in the right direction I would be immensely appreciative.
