Quick Question.

Without getting into every part that i have in my pc. Let me just state that its a High End Gaming system with watercooling.

Its been working perfectly fine for about a year now.

Today it i go over to use it and its off. I turn it back on get to the windows login screen and bam it shuts off. No beeps not errors just a cold shut down. So i turn it back on and reboot and bam off again not even at the windows login. This has happened now about 15 times. I have tried different outlets and surge APC's and same issue. My next guess is that the PSU has gone bad. Its a 750 watt Thermaltake its never had an issue before. I also leave my PC on all the time so is it feasible that this PSU has just up and died on my after only a year?

If any more specifics are needed to help me figure this out please let me know.

I don't have another PSU capable of powering this machine otherwise i would have already tried it.
 
Tear it all down, set it up on a piece of wood or a table, and start with the basics. Motherboard, cpu/hsf, one stick of ram, video card, psu and your keyboard, mouse and monitor. See if it will post, and if it does, add one component at a time until you find the culprit. If it won't post, try a different stick of ram. If that doesn't get you anywhere, try booting with no memory installed, and see if you get any beeps, and then do the same with your video card. If the beeps are present and correct, you probably have a dead psu. If there are no beeps, you could have a dead motherboard.... anyhow, try that and report your results back here..
 
Ok will do that.

One more question i work off this computer as well. I took the HD out and put it into another PC i have that was fully working. However i am unable to get past windows boot up now after i swapped HD's is this common did i miss something?

Or could this whole initial problem be based off a bad HD?

The new PC with old HD simply just keeps rebooting itself even if i try to go into safe mode

Yeah, your not going to be able to boot Windows off of that drive in a different machine. You can access the files and data on the drive from another machine, but Windows isn't going to boot......
 
Need help again with this issue.

I have stripped the computer down. Removed all the memory. Removed the HD. The only thing i had connected was the MB, CPU and the water cooling loop to the CPU. The Computer still shuts off randomly. I have also tried with a multiple different power supplies.

I am under the impression its one of 2 things:

1. Its the motherboard

2. Its the watercooling.

I cannot tell if the water is flowing in the loop. It always worked fine but i cannot see motion in the reservoir. If this is the issue wouldn't i get some kind of warning the CPU is overheating and not just shut off within 30 secs or less sometimes of powering on.

If you have any insights please let me know..Thank you
 
Try the stock HSF and see if you have any luck there... and you need to have at least one stick of memory and your video card installed in order for it to post......
 
Yeah i have got it to post. But it will turn off as well right after post. So i tried it this way to see if its just the MB. Funny thing is i have gone through 3 MB in building this thing and this one has been working for nearly a year now.

I will try the stock HS and Fan and see if that is it.

I will be back
