my windows pc is not booting,cannot reinstall windows - is this because of mobo or HD

[paglabhola99]

I need help .Since Ten days back one of my windows pc (os 8.1 x64) won't boot. The computer shut down(BSOD occured) suddenly when I was browsing . After that i showed " Reboot And Select Proper Boot Device " . I saw the bios settings whether HDD is set to be the primary boot device but i didn't found it .Also in the bios i saw no hard drive detected .Two days later i cleaned dust inside the CPU , took out my 2 ram sticks and inserted them.After that i started the PC and it worked fine . Some of the files were not backed up.So I started backing up. But i was very busy that day and i shut down my pc and left my room .They next day I switched on the Pc and started acking up . But again BSOD occured . i was unable to see BSOD messages as auto restart was enabled by default.After that i have not been able to start the PC .Every time with normal boot or safe mode BSOD will occur. Still some of my docs and downloads were not backed up. I have decent sort of knowledge in software but i am very bad dealing with hardware faults.I called one of my friends who have repaired a lot of windows pc. We didn't try any linus cd. But we tried to boot from genuine W8.1 and even W7 cd s.Every time during installation the PC froze. During initial attempts the partitions showed but after that it disn't show. We have changed both the ram sticks,tried booting with only one stick ,changed DVD/CD writer but nothing worked . What can be the problem - the mobo or the hard drive .I am very angry with myself. Some files still not backed up.I am cursing myself

I took the drive to another pc and it was not recognised.Should i change the hard drive or the mobo ( power was reaching all components).Is there any great software to recover the HDD

The day before the Pc stopped functioning I was downloading a p2p file(i don't download torrents often) .I was constantly getting "Write to disk error.Access denied". However i scanned it with EIS,mbam and zemana and everything was fine .Please suggest me what to do . Please help me to sort it out

To clarify, does the PC boot fine from Windows installation discs? If so, the motherboard and rest of the system should be fine. Since the drive isn't recognized on another PC, it has likely failed.

If you are installing the operating system on a drive that is failing, that may be the cause of the installation failure. Can you try a different hard drive?

Yeah, it sounds like that HDD is a doorstop.

Easy enough to swap though. And a perfect excuse to upgrade to an SSD if you have the money.

Ditto to all of the above. If the HDD failed, that would cause a BSOD and a subsequent "No boot device found" when re-booting, and if you connected it to another working PC, and it wasn't recognized, then it is likely that the drive is dead.

If so, and the original PC it came out of will boot a Windows install disc (without a HDD attached), then it's fairly likely that the original PC is OK, and you just need to purchase a new HDD, or SSD (preferred).

You can get 120GB TLC SSDs here in the USA for $35 on sale, or 240GB for around $60.
