Random reboots of PC

Ok dunno why since yesterday my PC restarted on its own 4-5 times, 3 times while playing Far Cry 3 and 1-2 times in windows idle! I noticed that the fans of...

What on Earth are you talking about? So you're just replacing the motherboard out of a hunch after its been made clear its simply an overheating issue and you need paste?

Ok but where can I buy a good thermal paste?
I am in between Achrafieh and Metn

I asked Ara about his thermal paste,he has this one: http://joyforevero.en.ec21.com/BN_G450_Thermal_Conductive_Grease--7742870_7742871.html
He claims that it's very good and durable,what do you think?

No,that's generic as they get. You know what? If you could wait a few weeks you could come to my house (It's around Metn) and I'll replace the thermalpaste with Arctic MX-4 (On of the best out there) and clean everything up.

And what the hell are you talking about replacing a motherboard? Do you here yourself? It's like saying you need a heart transplant when you have the flu or something. Stop jumping to conclusions. Computer reboots are usually very simple things to fix. If all this doesn't fix it, it might be from unstable electricity as DNA mentioned.

Buying the paste from amazon would be very expensive?

I hope you are still following this thread guys and that I can help with the random reboots.

My PC had been running fine on Windows 7 SP1 for a long time... until I started experiencing random reboots on a daily basis. It could happen any time, while playing a game, while the PC was idle, etc...

Just like you, at first I started monitoring system temps, checking RAM for faults, wondering if the PSU was dying, etc... everything checked out. All temps were normal, memory diagnostics tests were fine and PSU voltages were stable. I even considered replacing the thermal paste (Arctic Silver)
So I was really frustrated until one day someone (on some forum) mentioned that the error I was reading in the Windows Event Log was related to the graphics card's PCI bus, something faulty in the data flowing between the CPU and the GPU.

I was very skeptical about this assumption but I decided to do a research on the net and found out something very interesting. Just google "nvidia 320.49 crash" and read up.
Interestingly and, upon reading this, I remembered that those problems started right after I updated my drivers to 320.49.

Some articles advise you to revert back to version 314.22. Basically, most, if not all, drivers after 314.22 are known to cause problems for a lot of people. I don't know if the newly released driver has been fixed.

Surprisingly enough, I have been running on 314.22 for more than a week without a single reboot !

After you uninstall the 320.49 drivers and you reboot, make sure you use CCleaner which is a nice free program to remove unneeded files, registry entries, etc...

Good info but I am 99% sure my CPU needs thermal paste,I am waiting for my MX-4 from Amazon,I will post the results once installed,by next week

Make sure to clean the surfaces properly until the paper towel has no grey stuff coming on it anymore. And only use a small size of paste. The size of an uncooked rice, right in the middle of the CPU and click the pins of the heatsink in an X pattern.

It's better not to use paper towel or q-tips as this will most likely leave lint on the processor. Lint residue will interfere with the heat transfer from and to the heatsink. Use something that is lint-free. The cheapest lint-free paper I use is a coffee filter.

Also, check this webpage for the correct method, depending on your CPU type, to apply thermal paste: http://www.arcticsilver.com/methods.html

Multiple methods that achieve ultimately the same results. The vertical line way of application might be the most suited method for Arctic Silver 5, but that's a different compound than MX-4. Radically different, in some ways.

I don't think there was a thermal paste on the first place so I can bypass the cleaning step?

No, you have to clean it with alcohol, with paper towels until nothing comes out on the paper towel. On both CPU and Heatsink.

Just assuming or you actually removed the heatsink and saw that there's no thermal paste present already?
