I am running an AMD Phenom 9150e Quad-Core, 1.8 GHz (single hard drive)
4 GB ram
Windows 7 pro 64 bit
Service Pack 1
This machine is about 5 years old and was originally running Windows Vista. It began crashing and freezing a few months ago and I toiled with it for a while, ultimately deciding that it wasn't worth trying to clean and repair my registry. So I opted to wipe it clean and start fresh with Windows 7.
I'm not certain that I successfully wiped it clean. This was the first time I'd ever installed a new OS. I went through the installation process and when it asked me which partition to put it on (I only had 2 available, the primary and secondary. I mistakenly installed the OS on the secondary which didn't have enough space for the OS. My problems persisted and the memory failed the diagnostics test.
I decided to reinstall the OS, this time deleting the secondary drive altogether and wiping the primary. I wanted to ensure that the hard drive was truly wiped clean and I followed a tutorial to wipe the HDD manually, but was unsuccessful. The system came back with an error saying that it couldn't wipe the drive. So I proceeded with the installation and wiped the drive within the installation process.
My problem still persists. On occassion my computer will freeze causing me to hard reboot. Other times it will simply restart on its own, and still other times it will crash altogether (blue screen) and conduct a data dump "to protect from damage".
I've run the hardware diagnostics several times, each passing across the board. I'm tempted to replace my memory, but it only failed that one time. It passess consistently now and I'm wondering if the initial failure was caused by an impropper OS installation.
Regardless, I don't know what to do at this point or what my next troubleshooting step should be. Any guidance is greatly appreciated. Thank you in advance.
