After a few weeks of working well again, the other day my computer wouldn't boot into Windows. I use Win 7 Ultimate 64-bit. Safe mode wouldn't work either. For lack of troubleshooting options, I just re-installed again.
Now, the first time having to start over can be dismissed as a fluke, but after a second time, I'm starting to think something is wrong. How can I determine if my problem is related to the install of the OS iteself, or if there is some hardware failure causing this? Like I said, I have a SSD dedicated to the OS and maybe that contains errors. Also, every now and then, the display driver would crash. Most of the time it recovered but a few times it resulted in a blue screen, even though I had the most updated drivers.
So, I'm torn between thinking the problem is Windows, the SSD or the graphics card. I wanted to check the GPU by removing it and then booting, since I know my motherboard has onboard video. But I couldn't find a port for a monitor plug.
Is there some kind of software that will let me run a diagnostic on my hardware? CHKDSK says there are no errors on the SSD, but I'm not sure I'd trust that. Any help or advice is appreciated.
