It looks like you might have some memory corruption. It could also be OS/HDD corruption. I also see that you have an older motherboard and the website doesn't state whether Windows 7 is supported or not, but judging from your chipset
drivers, I don't think it is. This can also cause issues. I would like you to start off by running some tests and report back the results. We can go from there.
Please run these tests and report back the results
1. Memtest86 - Run for 7-8 passes -
RAM - Test with Memtest86+
2. Prime95 - Run all three tests for 3-4 hours each or until fail -
http://www.sevenforums.com/tutorials...t-prime95.html
3. Hard drive scan usings SeaTools -
SeaTools for Windows | Seagate - Both long and short tests
