Let me start with the system details: Biostar P35D2-A7 mobo, socket 775 Intel Core2 Quad core (Q6300), 8gb DDR2 PC2-8500 RAM, GeForce 210 graphics card, Windows XP professional 64 bit. The mobo uses the P35 northbridge and the ICH9 southbridge. I do not believe the mobo supports AHCI. I can't find any AHCI settings, and frankly I don't care. I'm more concerned with getting it to work than I am with the performance gains of running it in AHCI mode vs. IDE.
Then I cloned the existing HDD onto the SSD using EaseUS disk copy. Everything copied fine and worked great for about 4 days. Just to be clear, by working fine I mean it booted fast, ran a variety of my usual programs very nicely and overall performed fabulously.
Then things started to go downhill. On day 3 it glitched during the boot sequence. It made it to the Windows logo, but then crashed. It automatically went back into the boot sequence and came up all the way like normal, and I brushed it off as a glitch.
Day 4 things got much worse. It now crashes both before and after the windows logo, and is totally unusable. If it makes it all the way to the desktop, it will crash if I ask it do do anything, i.e. launch any program, or even open control panel. When it crashes, there is usually (not always) a blue error screen, but it flashes on screen so rapidly I can't read what it says. At one point it loaded all the way to the desktop and when I tried to open control panel it popped a dialog saying Windows did not have any virtual memory, though it's only done this once.
I've read a ton of forum stuff and nothing has worked yet. I switched it from SATA port 4 to SATA port 1 and there is no difference. I updated the firmware to the latest version 000F, no difference.
I'm desperately trying to avoid reinstalling the OS and consequently everything else.
Apparently I'm a total moron. I had installed some new RAM shortly after the new SSD. I've been so consumed with potential SSD issues I didn't think to remove the new RAM. Well, obviously I remembered it and of course that was the issue. 2 bad sticks out of 4. What were the odds???
