Problems

Hi guys, not posted on here much lately, as tbh since I bought my current setup it's been 110% bullet proof and stable.

I currently have:

Q6600
Asus P5Q pro
4gb (2x2gb) Corsair Dominator 1066mhz ram
Corsair H50 water cooler
Corsair HX 850w psu
Corsair Obsidian 800D case
ATI Radeon HD5770 GFX card

Think that is about it.

Anyway since I bought the mobo, cpu and ram, it ran at 3.4ghz on air cooling with no problems, shortly after I upgraded to the H50 cooler, and this allowed me to run at 3.6ghz for the last 18+ months all totally stable with nice sensible temps.

However a couple of nights ago, I had a powercut (no big deal had a few over the last 18 months and I use a surge protector).

Since the powercut, my pc is pretty much unstable now, even at the stock 2.4ghz.

It will crash (BSOD) within 24 hours, atleast once, and if I try and run imageburn even on the standard setting it will either fail on the 2nd attempt (giving incorrect answer) or it will crash the system.

So what I am asking is, what part of my system is most likely to have failed ??

Ok ever since I bought the ram, if I leave it set to AUTO it never runs at 1066mhz.

So at the moment in the bios it is set as it always has been:

Manually set to 1066mhz and the voltage set to 2.10 volts.

I will try pulling 1 stick out, and see if anything changes.

Power supply seems to be the problem. Does the power supply have a built in surge protector or is it in some kind of extension or socket?

Power surges are very well known for causing power supply failures which would greatly explain the unstability of your system.

Maybe the capacitors have fried or something, or the voltage regulators have became damaged in your PSU.

This could easilly result in your system not getting enough power, and thus only being stable at under 2.4GHz.

The unstability is caused when a significant voltage/current drop occurs in the system causing it to well, essentially miss a clock cycle or two. Happens so fast you physically wouldn't notice it, but your PC can... This is for when there is a lack of power anyways.

Try a different PSU.
Hope that helps, Emphacy.

I did wonder about the PSU.

The surge protector is in an extension lead (don't know if the HX850 has a built in 1 too).

Checking the voltage in the bios it is displaying the correct voltages (but I guess that doesn't mean too much in itself).

I don't have another psu here, that will work with my case (the 800D is pretty big and wires on the old psu are quiet short and it doesn't have any sata connections on it).

Ok the last BSOD it gave, it gave a code of:

0x00000050 does that help at all ?

Yeh only updated it last week

If the new driver causes a crash, then data in the BSOD said so. Is it a good driver or the wrong one? Well, things worked fine until you changed something. Another example of hard facts not provided.

With the next BSOD, read what it says. If the video driver is listed as the cause of stop code 50, then you know who created the failure.

Or you can do those other tasks, if for no other reason, to learn how to find before fixing future failures.

In the OP:

a couple of nights ago, I had a powercut (no big deal had a few over the last 18 months and I use a surge protector).

Since the powercut, my pc is pretty much unstable now, even at the stock 2.4ghz.

It's only been unstable since the power cut.

An since I last posted it has BSOD'd again this time the code was 0x00000000
