Computer Crashes When Playing Videos

Usually MY computer Runs fine But Sometimes when playing videos my computer randomly restarts. Through Research I was advised it was more than likely a software issue. I run Win XP and usually run a registry fixer and the problem will disappear for a few days and then return. IT is really random I'm not stressing the CPU or anything really. I'm just watching Videos on Hulu. I also Notice that sometimes the computer restarts if I leave it on for a while. At first I though it was because it was getting hot but it's not. I'm thinking it might be the motherboard. Let me know if you guys need anymore information.

Best solution

You say you rsystem doesn't get hot. Let's make sure. Please download CoreTemp and Prime95 from here:

Run Prime95 on all cores for at least one hour (with "Detect rounding errors" checked) and tell us what CoreTemp says about your temps.

Also provide your complete system specs including psu.

That error usually indicates a memory problem. The issue could be a bad stick, or insufficent voltage to the RAM sticks, or wrong timings, etc.

Stop testing, note the temperature of the core(s).

Remove one stick of memory and repeat the test. The repeat the test with just the other stick. What happens?

Checking BIOS to make sure the PC is using the correct voltage and timings for your memory is also indicated.

Removed one Stick of ram Test are running but not complete. Before the os Loaded I checked the Bios. The Timing Was set to Auto. And the Voltage was set to +100mV. I didn't change anything yet just wanted to rerun the test. Timing for the RAM is 5-6-6-18 and the voltage is 2.1 V. Core temp does not rise above 54 C

Good moves.

You could also download CPUID's CPU-Z and their Hardware Monitor which would tell you what your mobo has chosen for timings and voltage, respectively.

Ran the Test with only the one stick got

Memory Timing is good 5-6-6-18
downloaded the CPU-Z And the Hardware monitor
Voltage is Steady at 2.18 the RAM is Rated at 2.1V

Gonna Take out the other Stick and Rerun Test

Ran the test with the other stick and got

It may be odd that memory was set to +0.1V. Who built this machine? I'm a bit concerned that overvolting memory *could* have led to the otherwise unusual occurrence of a two-stick memory failure.

Let's get memory set to 2.1V. I guess you'd do that by setting that "+100mV" to zero or auto. Then retest with one stick. I'm hoping its "memory heat" lol.

Unfortunately, I am *not* an AMD guy. Maybe one will stop by who can help you more specifically.

If no one comes by soon, I'd suggest you make another thread describing the problem (your original post without the last two sentences), your spec, and that Prime95 fails shortly after starting with the message "FATAL ERROR: Rounding was 0.5, expected less than 0.4 Hardware failure detected, consult stress.txt file. ". Also add here that heat is not the problem since CoreTemp showed max temp of 54C.

I built the system but never had this problem Before. I'll probably REpost tomorrow thanks TwoBoxer

No problem. Truly sorry I can't do more.
