I would suggest a few things.
First, upgrade to a WD Black, as it is centered around performance and would suit your build better. Second, your power supply should be 600W, even though your build only requires 300W, because this will allow for overclocking, futureproofing, and more efficient power draw. Thirdly, I suggest using Kinguin for windows, as its $20 for a license key, and saves you plenty.

No, laptops generally arent worth the hastle to repair, due to their limited cooling abilities and small form factor.

Clear cmos, if that doesnt work check your power supply, it may have failed.
