PC keeps reset - help

post #1 of 15
Thread Starter 
My computer suddenly acting strange. It keeps reset so many times today. What I am thinking maybe the DDR3 bad or something. I try to run prime95 test for like 3-4 minutes a the pc shut down then reboot back. it also does that with normal use no load. CPU temp reading around 48C-53C. Any suggestion which component should I replace first ?
system spec.
Asus P6T Deluxe v2 mobo, i7-920, Gskill DDR3 (3x2gb) pc16000, Raptor drive, Radeon 5770 video, 850Wt Antec power supply.

I would start with the PSU. If you have a old spare or know a friend. Or go to best buy And "buy" one, test it out and once you know the results return it and get a quality one online.

As stated above, check the psu. Check your drivers as well, it could possibly be a driver issue. Had a problem similar to this in my parents PC. We think it was drivers after changing the psu, memory, and added hard drives and nothing fixed it.

Again, check the PSU. Also, check to see if your hard drive is failing. I just worked on my aunts computer that kept shutting down due to a bad hard drive. Also, just in case it is the hard drive, I would back up all of your data.

Sounds like data corruption, maybe Virus, Registry errors or a Driver issue.
Perhaps a recent Windows patch download went wrong.
Have you changed anything lately? New components, software, drivers, BIOS Flash or tweak?

Suggestions:
1.Boot in Safe Mode. If random reboots stop, Prime95 Small & Large FFTs while in Safe Mode.
2.Reset BIOS & verify settings for your CPU, RAM, etc. Boot Normally. If good then run Prime.
3.Reformat and fresh install OS.

If the above steps do not help, almost anything could be causing this. A bad USB Port, HD, RAM, MB, etc. I do not envy you. But if it were me I would first rule out corrupted software and then the overclock. I suppose it might be your PSU as others have suggested but Power Supplies don't normally fail in this manner.

I start with the PSU, and aafter the first boot to windows, it did reset once, then I use the back up image that was backed up 3 months ago restored that. it seem working fine now since last nite till now ( 11hrs on). This run without overclock yet. everything at default and the RAM auto detect at 1066Mhz instead of 1600. I will overlock back to it was before (3.8ghz) then will see if still reboot or not.
The antec power supply that was used on the system purchased on 09/2009. it's about more than a year or so. I wonder if it still under warranty from MFG.

Congratulations on apparantly solving the restart issue. But your conclusion is illogical. Please explain how a Restore can compensate for a dodgy Power Supply.

What he figured out is that it wasn't a dodgy psu issue. It was a software issue as mentioned above either with the registry, a virus or corrupted drivers.

I would slowly work on updating anything that you remember upgrading it the past 3 months and check the system one by one to make sure it doesn't mess up again.
If you put in a backup psu into the case, put the original back in there and see if it restarts. If it does, then its for sure the PSU. If not, its just a software issue.

SMOOCHIE :
Here is the quote from OP I was responding to.

"The antec power supply that was used on the system purchased on 09/2009it's about more than a year or so. I wonder if it still under warranty from MFG."

My point is why even begin questioning the power supply RMA if you are fully aware the problem was not a glitchy PSU at all, but instead almost certainly software corruption?
