PC keeps rebooting

PROBLEM: pc keeps rebooting

PC reboots, a while after start up. Rebooted when entering safe mode with networking, rebooted when entering window repair mode. Reboots in safe mode w networking

Managed to get into safe mode w networking, tried to attempt solution from this video: http/YouTube.com/watch?v=6S8bLMfH4Gs

But "choose what power buttons do" only had the first 2 options.

Can't seem to find it within "advanced settings" in "power plan" either.


ERRORS:
"The device, \device\hardisk0\dr0, has a bad block"

Level = critical, source = kernel-power, event ID = 41, task category = 63

Source = Service control manager, event ID = 7001

Source = service control manager, event ID = 7026

Source = distributedCOM, event ID = 10005

Source = Microsoft anti malware, event ID = 3002


PC PARTS:
i7-2600 3.4GHz

cooler master V6 (replaced fan)

MSI P67A-GD65 (B3) ATX LGA1155 Motherboard

Kingston 4GB DDR3-1333

WD 1TB 7200RPM HDD

MSI GTX560ti HAWK
(Arctic accelero twin turbo II)

SeaSonic X Series 760W 80+ gold fully-modular ATX power

Windows 7 home premium (64-bit)

____________________________________________________
GPU temp stayed at 37-40 C
Didn't check CPU temp in normal mode, couldn't check in safe mode.

Cover panel is off, high power external fan.

PC used for 10 hours
Scan took 6 hours, "limit CPU usage to 50%", I changed it to "20%" at the last 1/6 of the bar left.

I was scanning with Microsoft security essentials and doing work (multiple browser windows + PowerPoint) and had video running in the background for 7 hours.

Scanner detected "VirTool:Win32/obfuscator.XZ", I tried to remove it again (apparently I tried to remove it twice, 10 days before) it showed the error code 0x800700df. occured, saying that "the file exceeds the limit allowed and cannot be saved." again.

I permanently deleted the folder in D Drive (no shadow copy) afterwards and conduct a scan on the parent folder (limit CPU usage to 20%). It rebooted in the middle of it. Conducted quick scan, it rebooted in the middle of it again.

Went into programmes to remove the weird software(s) that installed itself somehow. (safe mode w networking)


OTHER INFORMATION: Was on a boot loop the week before until removing the RAM module from one of the slots fixed the problem. 3 faulty slots. I'm now left with 4GB RAM

(Before that) While looking for the problem, I cleaned up messy thermal compound and removed CPU chip several times (because compound went there), reapplied, and reattached.

Replugged:
-plug from the PSU to the mobo.
-plugs on the HDD
-plugs on the GPU

Dust blew the bottom of PSU with mesh filter plate removed, and the plug holes. (Thought it might be dusty and overheating or something due to that)

Everything has been dust blown.

Swapped out the stock cooler from MSI GTX560 Ti HAWK with ARCTIC ACCELERO TWIN TURBO II (250Watts)

Windows updates are up to 2014. Had not done most of the 2015 windows updates.


Would be great if any of you Technology-Gods could diagnose the problem. Thanks

Might want to bench it, have a guide that may help here:

So, in the end.... i reformatted, disk checked, changed the HDD, used an 8 GB RAM for the last working RAM slot.

Finally found out what it was, the Motherboard has overheated, eventually the last RAM slot would be rendered useless. It was a hardware problem.
