Random Restarts

[randomwalsh]

If, as you say, it was running fine then two things come to mind.

1. PSU - Dust, especially on the fan fins is a real drag !

2. CPU heatsink - Dust & cohesion. That sticky paste serves a purpose.

If you're offé with PC maintenance, strip and get rid of the dust, don't touch the paste!

Of course if your case vents are clogged with dust, internal temp will increase.

Just a bit of elbow grease.

I clean the pc of dust monthly and the thermal paste is new. Its not overheating as core temp does automatic logging and it never reachers the shutdown temperature.

Other cause is noisy power lines. Check for bulged capacitors on mobo and PSU (or try another PSU). In very rare cases (if not overclocked) faulty CPU.

I have checked mobo and psu and no bulged capacitors and cpu is stock.

Did the OP pull everything out? Just leave your prime HDD in also pull out your GPU and DVD drivers U only need your motherboard,cpu,ram,1xHDD and try again like everybody asked

I run the memtest via ubuntu live usb bootable with everything plugged and no errors came up. What difference would it make if I unplugged everthing and run the test again? Are you talking about another test?

it's as if OP doesn't want to fix the problem.

Not sure what you mean by this as I have done what has been suggested... its considered counter productive for someone to go to the effort of creating a thread and not want to solve the problem that the thread is asking help with.

Why wouldn't I want to fix the problem that is affecting my computer which I use daily?

turn off the computer, unplug all unecessary components internal and external (including HDDs, only leave your boot drive connected). Now see if the problem persists, run a stress test at this stage too. you haven't done this and it has been suggested multiple times.

I have done a stress test, Prime95 which was suggested by halohero and all that did was increase my cpu temps to about 94 degrees. Yes that is hot and near the shut down value of 100 but it wasn't causing the computer to blue screen. I know my cooling is a problem but under normal conditions the pc never goes above 50 degrees...

I have now taken everything out except my boot drive and will see how long my computer runs for before blue screening...

It normally doesn't lead to random restarts, but did you try checkdisk with system area option?

U need to remeber u can hurt your cpu/motherboard with temps like that, small things but ill never let my Cpu come near that temp.

Just checked Intel recommends max temp on that cpu not to go over 56 to 60'c :?

 

[randomwalsh]

ok so i took everything out except the boot drive and the pc run the whole weekend without a bsod.

Just put all the stuff back in and the bsod has returned...

So does that mean the power supply?

please list what you took out. I would put everything back in but the extra harddrives (depending on your list). could be a faulty piece of hardware that is causing it more than the PSU. The ideal is to put one thing back at a time and see when it fails.
