Odd stuttering and occasional BSODs

[Erwiiind]

Hey guys,

Over the last few weeks my computer has started stuttering like mad and frequently getting the BSOD. By "stuttering" I mean, my screen freezes, the sound gets stuck and I manually can't do anything for 1-3 seconds. Sometimes, the freezing is prolonged (10s or more) and followed by a BSOD which is usually STOP 0x00000101 . The stuttering happens at random, I cannot force it to happen; it does not happen more frequently when playing GPU/CPU intensive games. BSODs sometimes happen at startup.

My specs:

Windows 7 Professional x64
NVIDIA GeForce GTX 660 Ti
Intel Core i5-3470 @3.20Ghz
Asus P8B75-M LE
Kingston 8GB DDR3
1TB Caviar Green

All drivers are updated. Ran HWMonitor, no overheating at all. Ran Intel Diag Tools and HD Sentinel, nothing found. Have opened up and cleaned my pc. I also sent it to some IT Guys who cleaned it again, reinstalled a fresh Windows 7 since I didn't have an actual disk; but they stress tested it and said nothing had happened.

Some things I haven't tried yet:
Memtest86 since I can't find a secure link to dl it
The desk where my pc is right now, is made of metal, though no metal is touching the cables nor PC.

Someone told me it could be RAM problems.

Please help, I am out of ideas!
Thanks a lot in advance!
(Also excuse my shitty English, second language)

Not sure if this will help but try a program called "WhoCrashed" it might give you some insite.

I ran whocrashed and most BSODs were:

This was probably caused by the following module: ntoskrnl.exe (nt+0x743C0)
Bugcheck code: 0x101 (0x31, 0x0, 0xFFFFF88002FD7180, 0x3)
Error: CLOCK_WATCHDOG_TIMEOUT

Does this mean this is a RAM hardware problem?

Not sure.
Have you tried http://memtest86.com/ thats where i downloaded it from awhile back, should be secure.

Also check this web page http://www.bing.com/search?q=ntoskrnl.exe&form=PRUSEN&mkt=en-us&refig=84dd9106c0074907a30a638c73fd6742 for different ideals.

I've also used "tweeking.com - Windows repair" http://www.tweaking.com/ to help solve some issues. Just used it last night to solve a printer issue my mom was having. Maybe it can help.

Drivers might be the issue. I've used "Driver Booster 3" http://www.iobit.com/en/driver-booster.php its free.

Could also try stress testing it your self with passmarks "burnin test" http://passmark.com/ its free for 30 days. I've used it lots of times.

Thing is you gotta start narrowing it down one by one like your doing. Which is hard if you don't have the hardware parts to do it.

If you just did a fresh install I would think the software part of things would be good (unless it was a bad install) and that would maybe mean hardware issues like the RAM.

If you got the cash you could buy the professional version of WhoCrashed. I do believe it will give more info. (Research that first though)

Sorry I don't have a direct answer for you.
