I am an undergraduate computer science and mathematics student in New Zealand. My fields of interest are computer graphics, in particular the physics of light transport, and to some extent cryptography, as well as programming and software development in general.

comment Delete Remove 0 byte file Windows 7 64 bit
@AnselSimpson just add /F after "del", it'll force the deletion of the file. Like this del /F DOS-FILENAME. Or /f, I forget if it even matters.

Add the /F switch to nuke the file if it doesn't work. That's the only way I managed to get rid of Securom malware a while ago.

comment is there a way to stop mac osx disk encryption in progress?
Whatever you do, let the process finish, backup everything, then tinker with the settings. If you mess up while your files are encrypted, you are royally screwed.

comment Can you disable the GPU on a Macbook Air?
Mechanical hard drive also munch a lot of power (not SSD's though) so set it so the hard drive shuts down after like 5 minutes inactivity.

comment Where does Windows store CPU affinity settings?
Correct. Affinity settings are normally automatically set to the parent process's affinity, and initial system processes always have full affinity whereas initial user processes have affinity depending on the user's quota settings (usually full). There must be a third-party application somewhere modifying the defaults immediately after boot.

comment Display drivers have stopped responding and has recovered
Ah, good old TDR. Well, good luck, I never really solved this issue with my 6950. The only ghetto fix I can recommend is keeping your card's temperature above 55C, I know this sounds weird but the driver reset just stopped occurring above that temperature, and below that, some games and applications would simply instacrash. This is the only reliable fix I found, and it may not work for you, so YMMV.

comment Graphics card fails after ten minutes of gaming
Guys, remember he is probably reading the global thermal sensor, which often isn't representive of the actual thermal state of the card. Other sections of the card - in particular, the shader cores - are likely to be quite a bit higher. 90C is borderline critical temperature, and 60-70C on idle is way too high. Even if this isn't the OP's issue, he really should invest in a better cooling system if he remotely cares about his hardware.

comment Is the performance of a CPU affected as it ages?
I agree - with you - that the relative human perception of what is fast changes - with time as we repeatedly exceed limits - with faster hardware, note that there are ways around this, for instance by using standardized - benchmarks which do not account for software improvements or subjective bias.

@Hand-E-Food Five minutes?!

comment Windows 7 will not boot after sleep
Cannot reproduce on this board, and I also have an Intel SSD (120GB 330). Looks like a motherboard issue, @puttputt is your SSD controller in AHCI mode? Check in your BIOS.

comment Windows 7 will not boot after sleep
@Hand-E-Food could be, if so I apologize. That said, if according to your experience, it is necessary to close all applications before going to sleep, then it sort of defeats the point (booting could actually end up being faster, excluding the boot overhead). I will try to reproduce the OP's issue right now (P67) and investigate.

comment Windows 7 will not boot after sleep
I know this will bring about a lot of hate, but all I can recommend is to stop using sleep mode, it isn't meant for desktops (and if you have an SSD boot time should be a non-issue, right?). Otherwise, if it's the motherboard's fault you'll probably need to update its firmware... be careful there.

comment My computer was turned on in the midst of CPU change
@Synetech Clearly if it turned on by itself it was running in some way. He should have turned off the PSU switch at the back, and kept the plug in for grounding.

comment Will 250 watt be enough for my setup?
Just a quick safety comment, "almost" isn't good enough. The instant you exceed your power supply's rated capacity, you run the risk of it blowing up as well as random failures. PSU's are the worst component to cut corners on. Don't do it.

comment Extended Firefox use causes my sound to cut out
Why tagged firefox? And I think you will need to provide more detail to get a specific answer, this could be anything ranging from a virus to simply overheating.

comment Black screen after installation of graphics card
@DerekTownsend then the BIOS identified the card as functioning. Does a different graphics card (without changing cord and monitor) work? If so, the display connection on the back of your card could be dead and I would RMA.

comment How to force display through PCI video card when onboard graphics is not working?
@DavidSchwartz not always true, if you are doing GPGPU number crunching that doesn't produce realtime output you will want your good card to crunch in the background without interfering with the display, so you let the weak card handle the latter. But I agree this is a rare case.
