Win 7 x64 Freezes on start up
Hello,
I had been running Windows 7 Ultimate x64 for at least 6 months without any problems. The other day while just browsing around on my computer, Windows locked up - no BSOD, mouse doesn't move, keyboard doesn't respond. I did a hard reboot and now Windows continually freezes on start up. Sometimes it freezes on the 'Welcome' screen and other times it will freeze just seconds into loading the desktop.
I went into my BIOS and loaded my defaults. I then went into safemode (which works fine) and downloaded an updated BIOS which I flashed in DOS. This did not help. I backed up everything I needed onto an external hard drive and formatted my hard drive. After a clean install of Windows, everything seemed fine. After installing drivers and Windows updates, my computer randomly froze again and then the boot freezes began again. If I turn off all services, including Windows services, I am able to boot properly, which leads me to believe it may be a Windows service that is causing my system locks.
I have ran chkdisk and WD drive utility which have turned up no problems. I removed and reseated each stick of RAM and tested each one independently. I also ran stress tests on the CPU and memory with no problems. Temperature is not an issue. I checked and reseated all SATA cables. The only thing that I have not checked is that my power supply is giving a constant current.
The nature of how the freezes randomly began screams hardware, but the fresh installations of Windows and repeated boot problems scream software. I am running out of ideas. Any suggestions are greatly appreciated.
Thanks
