random restarts on windows 7

[Monty1]

Hi i recently bought a used pc that had random restarts as I thought I could fix it. System is a asus sabertooth 990 fx mb, amd fx 4170 with a Arctic cooler 7 pro rev 2 temp for cpu is 40 degrees was running windows 8 also a corsair 550vx psu. I added a gtx 660 cu gpu and a new sandisk ssd with a new install of windows 7 and 2gb of ram just to install everything and add more ram later also i reset the cmos everything was running fine 134 updates was installed then the restarts started to happen any help thanks.

Any slot you use will be ok. Now since you still get restarts the problem is the psu and in the worst case the motherboard. I hope you have warranty for what you've bought so you can replace them for free

I've changed the dram voltage from under 1.5 to 1.5 pc was running for 4 hrs no probs I'm working at the mo if still running no restarts I'll post back with the results thanks

Pc reboot after over 7 hrs so getting close maybe increase the dram voltage ?

Hi dram voltage went back to auto so must of typed the wrong value which I entered 1.5 so should input 1.50v or 1.500v as in bios dram voltage is running at 1.478v thanks

You don't need to change voltage it is ok as it is. But 1.50 and 1.500 is the same thing. Also try all slots so you can be sure motherboard is not a problem

Hi I've heard the fx 4170 uses more power than other cpu's voltage if it's a faulty psu maybe that's causing the reboot but will find out tomorrow if it's that and then it's prob the cpu or motherboard that's what will be left thanks.

I have changed the psu but still getting the event id 41 i have turned off the automatic restart to stop the computer from rebooting but getting the critical alert log every hr not sure if should of reset the cmos first before installing new psu maybe its windows being over cautious and now only the mb and cpu left any help please and got cpu-z running thanks

With what psu did you replace your old one for?

Hi i will try the performance power option 1st as this is what the original setting was on and reset the cmos hopefully this will finally work and it's prob Microsoft that causes most probs thanks.

Hi just want to thank everybody who contributed to this thread as finally this issue is now solved as mentioned earlier, and it was indeed the power supply thanks.
