Hello, I´m having a tough time with this issue. 2 year old build boots fine, gets into windows 7 - 64 bit Home Premium and runs low intensity programs (outlook, IE, word, excel etc) no problem.
But if I try gaming (any game) or running Prime95, shutdown occurs (30 secs to 2 mins) and I cannot get it to power back up again unless I flip the on/off switch at the back of the PSU. I can then boot up normally without problems. The shut down is complete - just a black screen and all fans stop working.
Temps are fine using HW monitor, CPU idles at 32C mobo at 27C. Gaming temps before shut down around 46C for the CPU so it doesn't look like a temp issue (I`ve reseated the sink about 5 times, each time wiping off the paste and reapplying). CPU is not Oc´d, runs at 4000 (stock). BIOS reports similar temps even after shutdown.
Thinking it might be RAM, I tried memtest86, after 4 passes, no problems found. Also did the windows memory test, no problems found. Tried booting with 1 stick, then the other, then both again - same issue. Tried different frequencies 1333 (BIOS default) 1600, and 2133. Same issue
Swapped out a corsair CX600 PSU that was showing low voltages on the 3.3v. The new PSU shows all correct voltages. Did a paperclip test on this new psu, case fan spins no problem, psu fan starts up and then stops (apparently the tx650 only runs the fan if its under extreme load so I´m thinking its passing this test). Unplugged all connectors and replugged about 3 times. Plugged into wall socket direct as well, same issue.
Drivers are the latest, though I rolled back the catalyst from 14.12 to 14.9. so is BIOS. Reinstalled sound drivers, lan drivers etc. Same issue.
Ran ESET Antivirus, including online scanner from ESET both in safe mode and normal mode - no virus detected.
I even reinstalled W7 just in case - same problem.
I´m starting to lose my mind lol so any help is appreciated
