Random freezes/lockups

[Lucah4xx]

I've had this system working fine for a year or so bit it is causing problems for a while now and it is getting really on my nerves. So to jump right in these are my specs:

Windows 7 home permium 64bit updated from vista
Intel core i7 920 2.67Ghz
6MB RAM
Nvidia GeForce GTX 275
Gigabyte EX58-UD4P


I have formated it still no luck.
It freezes at startup or later on seems random to me, I have Chrome, Skype/teamspeak and League of Legends running most of the time. When it freezes all sounds will repeat for a short time and then continue for about 5 seconds.

Help would be appriciated!

If formatting didn't do the trick and it's still causing problems for you, then it's most certainly hardware issues. It's just a matter of figuring out exactly what hardware it is.

I am unable to read the syslogs because they're in a different language, but I can use the two crashdumps. One reported your video card drivers (or video card itself) timing out. Note that this doesn't exactly mean there's a problem with it, as something else could've been holding them up. The other crashdump is a bit more interesting. It shows what appears to be a shift of two bytes in one of your CPU's registers. I cannot ascertain how this happened without access to at least a full kernel dump of the scenario. However, it does kinda lead me to believe it's hardware-based.

Here's a battery of tests you can use to try and narrow down cause:


RAM: Memtest86+ - 7+ passes
CPU: Prime95 - Torture Test; Large FFTs; overnight (9+ hours)
GPU: MemtestCL - Run twice (if any of the tests work on your GPU)
Drives: Seatools - All basic tests aside from the Fix all or the advanced ones.

All of these (excluding MemtestCL) are included in the UBCD if you prefer a Live CD environment (which is the best environment to test hardware on). Note that Prime95 currently does not work on the UBCD. Also, please provide us temps/voltages using HWInfo with Sensors only option checked. Log two 30-minute instances: one for idle, and one for high load. Preferably if you can get system to crash in high load let it log until crash.

Thanks for the reply

I asked my brother if I could use his RAM so I'll be testing that tommorow.
As for the temps, SpeedFan gives me: GPU 45C, RAM 36C 31C 45C, all four cores 35C in idle

I'll try to use the tests you gave me tommorow as it is late here now.

Also I suspect this is my GPU's fault do you have any experience with this? Something with corrupt drivers?

I switched my RAM, I now have 8GB.
No freeze at startup I'm keeping my fingers crossed

EDIT: It has been running smoothly for about 5 hours!
I will be updating this thread for atleast 2-3 days.

2nd edit: So far no freezes only 1 sudden lag spike for 1 second.

Hmm, if the lag spike was not a condition that repeats itself it may just be a solitary fluke and is most likely not conducive of any existing problems.

Have you managed to run the hardware tests?
