I would always back up my files during a reinstall, even if I don't delete or format the data partition. The data can still be lost in rare cases.
You must reinstall all programs and games, as explained in Clean Reinstall - Factory OEM Windows 7. Some games like Steam will still run from their Programs File .exe but should be reinstalled eventually.
I scanned the system with malwarebytes and there was no malware. Is myHDD is slow compared to the processor and graphic cards?Do you think the BSOD's could be because of that?
I'm not an expert at anything so this is just one other avenue to explore. A few months ago I began getting BSODs several times a day on my laptop. Each BSOD had a different reason given. Sometimes my lappy would slow to a crawl. Several scans with different antimalware products showed no issues. I finally figured out one of my memory modules went bad (possibly due to some thunderstorms earlier that week.) Once I replaced the memory all was good. Not sure this applies in your case but . . .

I agree with Lee that testing the hardware would be a good idea. I would also test the HD to get that out of the way. These tests as well as others are in the Troubleshooting Steps for Windows 7.
Work through all of the steps as well as any given by the BSOD experts in Crashes forum to get to the problem solution. Once you exhaust all of the troubleshooting steps you can try the Clean Reinstall.
