Random Reboots Because of PSU?

Dear community. I have found many good solutions to my problems in the past here, and i thought i would try to ask you for some help, now that i seem to be at a loss regarding this pc.

Long story short:

Asrock 970 Pro3
700 Watts Generic Psu with no discernible name (prebuilt pc i got cheap)
QuadCore FX-4300
GTX 550
8 GB Kingston DDR3-1333

So, a month ago, i bought a new cpu. A fx4300, and a r9 280 from Msi.

The R9 280 XT, had a horrible coil whine (atleast i thought it was the card), and i recieved orange/bluescreens when playing games.

I RMA'ed it, and they just reported to me today that they found the Card to be working fine after 7 hours of furmark (dear lord), and 16 hours of unigine loop (poor card.) No noticeable whine was found, and no bsods.

I have a feeling it might be my PSU now. Could the PSU be the cause of the "whine" and bsods?

My cpu temps are low, and i do keep an eye on them.

Today, with the GTX 550, i have these random reboots, and they dont show me any bsods. The reboot is done in a split second, and seem unrelated to any activity i do.

The event log shows nothing but a 6008, and just informs me that windows is sad that it didnt know what hit it.

I guess i am asking if ordering a new PSU is madness.

Thanks for reading!

Also I just saw you had NVidia and amd GPU, so you need use the Driver Sweeper http://www.guru3d.com/content_page/guru3d_driver_sweeper.html to clear the driver then install the new GPU driver.

If you don't have spare gpus, then using the MSI afterburner to underclock the GPU http://event.msi.com/vga/afterburner/download.htm also download and install the HWMonitor http://www.cpuid.com/softwares/hwmonitor.html to reads PC systems main health sensors : voltages, temperatures, fans speed, like the +12V, +5V, or +3.3V.

And don't oc your cpu or gpu yet, you need find out what causes the PC freeze, after you only find out that you can oc, otherwise you will make this more complicated.

It could be the PSU, or something else.

Do you have the newer BIOS for the MB? Usually you don't want to update the BIOS, but if you have problem then you may consider it, also chipset driver http://support.amd.com/en-us/download/chipset?os=Windows+7 or other driver for the hardware.

And after update all the driver, you can test the PSU to see it works on other lower powerful GPU or not if you have one or borrow from your friend. If the PSU works with the lower powerful GPU, and the problem is likely from the Generic psu with no discernible name, because those psu usually is the bad one.

One more thing you should run the MemTest86 to test the RAM, make sure it is not the RAM problem. http://pcsupport.about.com/gi/o.htm?zi=1/XJ&zTi=1&sdn=pcsupport&cdn=compute&tm=7&f=00&su=p284.13.342.ip_&tt=65&bt=6&bts=56&zu=http%3A//www.memtest86.com/download.htm

Thanks for the advice! When i go to the amd driver page, it throws an error at me, and when i chose the "automatic driver finder tool" thing, it says "no supported os or product found".

I do not have any catalyst stuff installed, since i was afraid it might be conflicting with the nvidia gpu. Maybe that is a mistake.

Bios is fully updated before i RMAed the card, just to make sure.

I have tried the memtest, to no avail either. But thanks for the suggestion, i didnt know about it till not too long ago.

Man, i am grasping straws here.

I dont have any spare gpus to test, but it i can try to find one. The reboots are getting worse and worse now. I defaulted back to the original bios settings, i had a slight oc. Did not do anything in the luck departement.

It seems totally random when it happens, and is mostly when idling so far? But not always. If im lucky, my screen freezes for a second, then instant reboot. No bsod, no bccode...

the voltages are at a stable 12.0 odd numbers. I wonder if it is not getting enough power.

thanks for your help, i will stress test the cpu a little, and watch the voltage. If i dont report back, dont shed any tears for me. We had a glorious run, me and bertha.
