    Processor Intensive Applications Crash PC


    Everytime I run a processor intensive application (Video Compression, Running Market Simulations, etc.) After five to ten minutes my machine crashes.

    If I run the same applications with shorter jobs it completes and the machine doesn't crash.

    This is a hard crash where everything just blanks out.

    I haven't made any hardware changes to the system and this issue is a new issue.

    I ran all my avg anti-virus, ad-aware, and advanced system care and everything is running fine.

    I am stumped.

    What do you mean everything just blanks out?
    It just shuts down? Freezes?

    Welcome to SF, crashy

    On the first view it looks to me like a Thermo problem. Any chance the machine overheats (due to dust build up in the heatsink and/or fan(s)?
    Here are some applications that monitor your thermal diods:

    Core Temp

    Real Temp - CPU temperature monitoring

    SpeedFan - Access temperature sensor in your computer

    see what temps you get under load and get back to us

    I think you may be right. I will try out the apps and report back. I will also try cleaning dust from the cpu area.

    If it is a temp issue how can it be resolved? I have an Antec Sonata 2 case that has three fans. Do CPU's run hotter over time?

    Absolutely...depending on the actual situation/is the pc on the floor or on a desk, are there pets like cats or bunnies around etc the dust build up can be too much in as little as 6 months
    The more dust build up you have, the less effective is your cooling thus the cpu gets hotter and eventually shuts down (or worse gets destroyed in the process)
    I usually just use canned air and a stiff paintbrush/old toothbrush to remove dust from the fan blades and the heatsink "griddle" but in extreme cases I take off the heatsink, clean it out, apply new thermal compound and be good to go for another 6-8 months

    The working for short times but the crashing over longer periods is as good as a dead giveaway

    You might want to also clean the PSU fan aswell. If it gets to hot your PC can also shutdown. BTW what is the wattage of your PSU ? (it's not in your system spec)

    Yeah, I agree. I've had an apparently similar problem with PC before. It seems that sometimes components automatically shutdown the computer when a certain temperature is reached without informing you of any errors. You should clean inside for dust, maintain air circulation, or if its a laptop try one of those fan bases or a lower power setting.

    Just don't try to open the PSU...the capacitors in there hold a nice (un)healthy charge...they have warning labels for a reason
