Try it with the video card in.
My computer runs fine with the 1 hr test
So then we tried using the Power supply test on OCCT in Windows 8 and it crashed. I was actually happy about that. I thought maybe we found the problem. So we hooked up a new power supply and ran OCCT power suppy test again it crashed too.
I tried running Furmark and after about 4 minutes it crashed too. With the new power supply in (not the old one)
This is with no videocard in, just one stick of RAM, SSD, motherboard and CPU.
Someone told me that OCCT running for an hour should suffice for both CPU and Mem test check to indicate I have no major errors in either area. So where to go next?
Does this seem like it is pushing toward a motherboard problem? What should I try to find out?
