Weird PC lock up ,please help

post #1 of 9
Thread Starter 
A few days ago the sig rig started to lock up. So I thought well maybe the OC went bad or wasn't stable anymore so I went back to stock. The computer still locks up at stock. Not nearly as often but I would say after a good 10 hours of running it does. I don't know what else to check or what might be bad. ANy ideas or suggestions would be great.

Three things I'd check:

1. RAM. Run MemTest86+ and see if it picks up any errors.
2. PSU. Your PSU may not be enough for your powerhouse rig.
3. Software/driver issues. Have you added any new hardware recently or updated any drivers?

Hope this helps!

quick question.

ARE you using windoze?


Seriously - maybe an icky environment?


hardware wise though.
What are your temperatures like?
ARE YOU SURE, EVERYTHING is stock?

Ram is good, PSU meets the requirements, and the drivers are all the latest from NVIDIA, but then again I am running vista so that could be the issue.

i dont think vista is the reason. Boot into safe mode and just do basic maintinace, try reinstalling drivers for your hardware and see if that helps.

If the ram is good, then it's good. I've never had ram burning out.

By saying the "PSU meets the requirements" what do you mean? Does it keep at least 11.6V on the 12V rail? Anandtech has a very interesting testing methodology for PSUs, you should check it out. They've posted a PSU review today, and what I found very interesting was the PSU diminishes its power output with rising ambient temp. The 5V was particularly affected, but the 12V was affected also, dropping further than usual.

You have a HE, aka silent as far as I remember the branding of Antec's. I wonder if it's not a ventilation problem for the PSU, as nothing locks up randomly. With heat building up in the PSU radiators it decreases the output voltage, which in turns leads to a crash. IMO your PSU works at 80%-90%, it's at the limit anyways, a slight drop in output voltage (with a constant wattage demand from the computer) makes it increase the current, thus the heat (W=V*I if W=constant and V falls, I has to increase). This is a cascade effect that may overheat it and subsequently fail.

Vista is imo a stable OS. I never had a lockup in 2 month of use, I just got fed up with it. nVidia drivers were crap for vista, but they always seemed good enough.

To conclude, I would search signs of overheating components, specially the PSU and the NB/SB.

Just as a general comment, wattage ratings by themselves don't tell the whole story when it comes to PSUs. More important are 1) Amperage from your PSU's 12V rail(s); 2) performance under duress (high load + high temps); and 3) actual power draw (Amps) on the individual rails (particularly on multi-12V rail PSUs).

If you have a multi-12V rail PSU, and your graphics card and CPU are sharing the same rail, then it's very likely that there's a shortage of power delivery, which could cause the lock-ups.

Hope this info helps!

Guys I am really confised with this one, my ram passed memtest, and I have done over 8 hours on orthos, so I know my system is stable. I bumped it up a bit with a mild oc and it is also stable on that. It only locks up and crashes when playing WoW.Temps are below 55C also. Here is some pics of my settings:
