Cause for computer freezing and restarts
Posted 23 June 2012 - 09:20 AM
I have a Q9450 2.66ghz
2x2gb + 1x4gb corsair 1333mhz
Corsair HX850 PSU
Nforce sli 790i ultra
Xfi fatality pro sound card
have just recently replaced power supply (almost positive it is not the psu at fault here) and the system boots up fine, however once i get to windows welcome/login, the comp often freezes or more often restarts itself, sometimes it will let me log in to windows and everything will seem fine, can even be using the comp for an hour or 2 (although thats rarely the case) and then it will freeze with a sound loop or just restart. Tried safe mode, once strangely the comp froze loading safe mode files, but outside of that I think loaded up and stayed stable. I ran disk check on a hard drive I thought was causing the trouble and it said it was fine, ran memtest however and every time I ran it the comp froze within 20-30 mins, not sure is that just an indication of a ram stick/ram slot being broken or what. Graphics cards are green lights all the time even during the freeze + sound loop. Not sure if the sound card is at fault or its drivers, have rolled back the drivers on everything and uninstalled almost everything minus speedfan, memtest, ccleaner. Anyway any ideas? I personally think it might be the ram or the slots but im unsure how to check this sue to variability of the freezes and the restarts. One last thing, after about 4/5 restarts that occurred in quick succession i got the POST- the system is now in safe mode, reset cpu or cmos, this went away after I restarted the comp. Appreciate your time guys.

You might need to bump your memory voltage (possibly northbridge too) since you're running mixed densities. 4 GB sticks are sometimes issues on older choosers.

In any case, if Memtest freezes (which it should never do at stocks settings) than you have a memory related problem. high FSB, wrong voltage, from Trims, it could be anything. drop it down to 1 stick and try again after checking the bios

The little bit of extra voltage might be the silver bullet that fixes it.

the power button on my comp which has worked for 3/4 years is now it would appear decided to change its identity!! and its now a reset button, which would be fine, but when I shut down the comp I cant start it back up unless I use the mobo start button, any ideas?
seems your power button simply cant hold the "ON" state as it should, might be broken. it turned out like a buzzer button like the way your reset button does.
