My PC freezes for a millisecond every 2-3 seconds and I don't know why! I've replaced the CPU, motherboard, heatsink, fan and main HDD to a SSD (do sig now out of date) and still it is doing it. After replacing the HDD with an SSD it ran really well for a few weeks but it's doing it again now. Maybe it's somethin software related? I did a clean install on the SSD which but when the problem came back I rolled Windows back to that point and it made no difference. I've done lots of searching on Google and there are so many causes. Last night I did a memtest for 16 passes and it came back with no errors. One thing I haven't looked at is the PSU since I don't have a spare but I'm thinking that's less likely seeing as it's relatively new.

SPEC: Intel Q9650 @ 3GHz, XFX Geforce 275GTX, 4GB Corsair XMS2 RAM, Corsair HX 620W, ASRock P43DE.

PLEASE, does anyone have any idea or know of a forum where I might be able to get some help?

I'm wondering about DirectX11 now. Hmmmm, though I suppose the DX11 cards won't be out for some time.

Edit: How much juice would a GTX275 need do you think? I've submitted a support request with XFX now just to see what they say.

I have a Corsair HX620, which isn't enough for the GTX295 but looking at prices I couldn't afford that anyway! Well over £300!! I thought it had been out for a while too. Not really sure how much money I have, will check.

Thanks for all the suggestions. I've tried all of the above and still no joy. I think it's time to face the music. On the up side though I get a new GPU.

So, what would you recommend for my system? I've been looking at some of the newer cards and they need about loads of power cables! Not sure my MOBO can accommodate!

Thanks for all the suggestions. I can't seem to find the SMART setting in the BIOS so haven't done that. The noise has now stopped so I can't work out which one it is. The new HDD is on its way though. I've backed up everything onto the Home Server so I'll have to try and catch it. Might leave the PC on for a while to see if I can get it to moan.

No, the driver is the latest driver from NVIDIA themselves.

Here is a screenshot of the main tab so you can see the stats. All looks Ok to me.

EDIT: Except the GPU and Memory clock!!

[QUOTE="richyroo1"]

[QUOTE="Luminouslight"]What drivers did you download? Do you know what its temps are? Are you running overclocked? It sounds to me that the fan has gone dead and when the temps get to high the card becomes unstable and crashes.Luminouslight

The driver is version 190.62 date 21.08.2009 official drivers from the website. In device properties it reads "Windows has stopped this device because it has reported problems. (Code 43)" I then clicked 'check for solutions' and got "Could not load driver software"

I haven't checked the temps as yet but on turning on the pc the fan did not start for a couple of seconds and then started but isn't going very fast, however, I'm not sure whether this is normal or not. Not sure what else to do at the moment.

The post above about the fan is about the fan on the GPU. When I turn on the PC the GPU fan does not start turning for about 4-5 seconds, then seems slow.

I've just downloaded GPU-Z. For some reason, on the sensors tab, the GPU and Memory clocks are stated as being 0.00MHz, I don't know whether that is significant. The temperatures are 64.8 (GPU) and 60.8 (PCB) and the fan is running at 60% at 1474RPM. Those figures don't seem too bad to me. What do people think??
