PC Seems to Randomly Shut Off

Specs: Windows 7
One month ago my PC just shut off. I instantly Press power and it boot right back up with out question. This ruled out overheating in my boot as normally if that is the case it wont bot back up right away. All was fine and I remained confused.

3 Days ago it did it again. All was the same. Booted up. Remained confused.

Last night it did it a third time. This was different though. This time it wanted to run CHKDSK. I said no. It froze. I hard reset and ran Startup Repair. Two hours later it restarted and wanted to again run CHKDSK. I said no. It froze. I hard reset and chose start normally.

This time I let it run CHKDSK. After completely Stage 2 of 3 it would restart and run again. It did this about 6 or 7 times (I stopped watching and played Tomb Raider for 2 hours) before it entered Stage 3 of 3 and actually booted into windows.

The drivers for my wireless keyboard had to be reinstalled, but everything else seemed fine. I Remained confused,

For good measure today I shut down and CanOAired every fan in the the the PC. When It restarted it ran CHKDSK twice and then went into windows. All seems well.

I remain confused. Anyone have any thoughts or help. FYI I am poor.

Run Memtest via bootable CD. No errors are acceptable. Replace memory if needed.
Run hard drive utility from your hard drive manufacture's site (Seatools from Seagate will work on most drives if needed), also via a bootable CD that you burned from ISO image. Use the longest test. Minor errors will be repaired, but too many or major ones will mean you need to replace the hard drive.
Check your real time temperature with HWMonitor, or similar. Idle, general use, and hard use (or gaming) numbers are important. Post them in degrees C.
Post all results and include system information (make and model number or component list with model numbers.

You have to be a little bit crazy to keep you from going insane.

Ran tests. Bad Sectors came up on HDD. Repeatedly. Like 10-15 errors every couple of hours show in Event Log.

Set CHKDSK to find and repair bad sectors. Event log now only shows 1 ever few hours. Will run again tonight.

WD Diagnostics could not retrieve SMART status. Will see if SMART is enable in BIOS.

WIll keep this updated.

After running a second time the PC has been running for 6 hours and not one single Bad Block error has shown up. I, however, am still getting the Following:

The HP Health Check Service service failed to start due to the following error:
The system cannot find the file specified.

The driver \Driver\WUDFRd failed to load for the device WpdBusEnumRoot\UMB\2&37c186b&0&STORAGE#VOLUME#_??_USBSTOR#DISK&VEN_GENERIC-&PROD_COMPACT_FLASH&REV_1.01#058F63626476&1#.

The ScRegSetValueExW call failed for FailureActions with the following error:
Access is denied.

If anyone can provide helpful support for these remaining issues I would be very grateful.
