If you have run Memtest86+ for 5-6 passes or overnight, the HD makers HD Diagnostic extended CD scan, and Disk Check on all partitions, checked for BIOS update or reset the BIOS
then I would look at the install unless you followed all of the Best Practices given in Clean Reinstall - Factory OEM Windows 7 which are different than installing XP when handling drivers and on what tools and methods work the best.
This is a specialty of these forums so you might as well use us to assure you have a perfect reinstall. Then you can focus again on hardware if necessary.
I just connected to look at a Grandmas PC who was reinstalling and swore she followed all the steps in tutorial, yet the wrong version was installed on the data partition, the old Win7 was still in C, and the boot partition had been cut out of the picture. So we dont just assume anyone gets it done right, much less done perfectly.
If you want to try everything to get it started and perhaps discover the boot problem first then follow these steps for Troubleshooting Windows 7 Failure to Start. You might also have infection which the steps check out first.
Thanks
A little late in posting here. I encountered same problem. Did a factory reset, and that took care of it. My ram was also loose for some reason. Needless to say don't use Windows much anymore, only when the macs are not handy.
Since you're using the bloated factory preinstalled Win7, may I suggest as a project you experience for the first time native perfect Win7 performance by doing a Clean Reinstall - Factory OEM Windows 7.
You may find that without the bloat and duplicate utilities which conflict with better versions built into Win7, Win7 will beat any Apple OS on comparable hardware.
