The Speccy profile for my husband's PC is here: http://speccy.pirifo...4Rjj6r5FGf4BEP1
Yesterday, I took all of the RAM out of his machine & reseated it. One of the memory chips wasn't secured on one side & so I thought that was the problem.
However, today when my husband tried to bring his PC out of sleep mode, instead of restarting Windows 7, a red LED light on the front of the PC began blinking & this time, the machine emitted 4 beeps, paused, 4 beeps, paused, etc. My husband shut the machine off, restarted it, & it booted into Windows 7 just fine.
When we bought machine, it DID NOT have the 2TB hard drive or the Turtle Beach Rivera sound card installed. I added those; the hard drive was new & I pulled the sound card from my husband's old PC.
The computer's prior owner said it had always worked fine for him & thought that a loose RAM chip and/or the sound card were causing the problems. He suggested I reseat the RAM, which I did. The next thing I was thinking of trying is to remove the sound card.
I have also gone into the power management in Windows 7 & changed the setting so that the computer can't go into sleep mode since that is when we have the problem, upon trying to wake it out of sleep mode.
The original error message has not appear since I reseated the RAM chips, nor has the the flashing LED light & the three beeps occurred.
Please let me know if you need more information.
