I have a Dell Inspiron 620 that keeps getting random BSOD's x124. The original configuration was an i7-2600, 4GB Ram, 500GB hdd. It has always given me the same BSOD, but I planned on upgrading it anyways and figured the BSOD was hardware related. I added a Gtx 550 ti, OCZ ModXStream 600w PSU, Samsung 830 SSD and 8gb of ram. Along the way, I still have the BSOD problem.
I have reinstalled windows 7 x64 about 5 times, including once from a usb key that dell sent me. I have returned the computer back to stock specs, and still have the BSOD. Dell keeps looking at software, but everything I see online points to a hardware issue.
Bluescreen view shows that the crashes have been caused by hal.dll and ntoskrnl.exe at the below addresses with the original dell configuration.
Unfortunately the 0x124 error is pretty generic, so I would start by running Dell's built-in diagnostics. Press F12 at POST, and then select the diagnostic option, and come back in about 30-45 minutes.
It also wouldn't be a bad idea to let memtest86+ run overnight, since I've been bitten by Dell's PSA+ memory checks not being effective in the past.
I ran the thorough diagnostics and they came out normal. I didn't do a mem test, but i have have had two completely different sets of ram in the computer and it blue screened on all of them. Any other ideas?
