Hi guys, I recently bought a fairly decent PSU, a Cooler Master 550W jobbie. I am very pleased with it. BUT.......
I have done a quite major overhaul of the whole PC since Xmas, including new Graphics card, (changing from nVidia to Ati), new case, new CPU cooler and a new HDD.
I usually use a linux OS, but I have MSWIN 10 tech preview. Since the rebuild I have been having some problems.....
When I use Windows, it often crashes/blue screens with a variety of messages given, none of which are very informative.
OTOH I ran Prime95 at torture settings CPU/RAM for 5 hours yesterday without issue, until I stopped the test. When it promptly crashed.
I have also run a quite intensive game for a couple of hours, which behaved perfectly, until I stopped playing. It then crashed.
All this would not perhaps be surprising, as I am using a beta/pre-release OS, but IF I start my usual OS straight after a Windows crash, it also fails to start. My usual OS (openSuse Linux) is normally rock-solid.
My first guess is that something is getting hot. or is somehow not behaving WHEN IT IS COOLING DOWN (?)
It is not the CPU, I have the new fan running at MAX, the CPU will not go above ~52C even during the stress test.
Temperatures reported from Mainboard and GPU and HDD's are also very cool indeed.
It could be a memory DIMM moved or dislodged whilst rebuilding (I hope it is!) Easy to test and resolve.
I have done the windows memory diagnostic, no problems were found, I also ran MemTest for a while, but have not done a full overnight one dimm-at-a-time stress suite, as we all know that is a quite annoying task (and my PC is quite noisy ATM !)
Also I guess a cable slightly not seated etc. But this would usually show up in normal operation of the openSuse Linux install as well as the Windows one.
The new HDD only has the Windows 10 on it, the Linux install is on a separate SSD.
If it were not for the fact that my linux install also misbehaves AFTER a windows crash, I would put it down to drivers, the Windows install itself etc etc.
So there is a possibility that the new PSU is somehow not working correctly. This would be ENORMOUSLY difficult for me to pin-point...And even if I did decide it was the culprit, it might well behave perfectly on a test bench or in another rig(?) (!!)
Any tips or advice please? How to proceed?
Any other possibilities?
I have the old PSU, but it is a cheapo and underpowered for the new GPU. Are there any ways to test a PSU? I have lm_sensors on Linux and SpeedFan on windows, all voltages are in range. I suppose it is possble to poll/log those voltages using SpeedFan?
FYI, here are some of the Blue-screen messages I have had:
DRIVER_IRQL_LESS_OR_NOT_EQUAL
IRQL_LESS_OR_NOT_EQUAL
KERNEL_SECURITY_CHECK_FAILED
APC_INDEX_MISMATCH
ATTEMPTED_WRITE_TO READ_ONLY_MEMORY
KMODE_EXCEPTION_NOT_HANDLED
I really hope it is NOT the PSU, as I am very pleased with it, and it would be a MAJOR PITA to change it!
