hey guys,
I have a Q9450 2.66ghz
2x2gb + 1x4gb corsair 1333mhz
Corsair HX850 PSU
Nforce sli 790i ultra
Gtx280 sli
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.

I assume everything is stock?

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.

i would start by testing all your ram , individually with mem test then if all pass move onto your temps on your cpu . if the temps are fine then check your hdd with crystaldisk info , on all drives . if that passes move onto the graphics card , check temps again and if need be remove and re-install the card . after that look at the psu , if you can use a replacement as sometimes if they are a bit old they can be unstable , hope it all goes well for you and let us know if anything pops up , ps have a look in event viewer for any clues like system error messages or software errors .

U mean stock drivers? The only thing about the ram is that I already figured the 4gb stick which is new, might be the cause of the problem and so I have already tried removing that 4gb stick, tried individual ram configurations of the 2 2gb sticks and same problem also. Any ideas?

[m89a3]

oh and the hx850 psu is brand new aswell, problem has only been occurring since I installed new psu, new 4 gb ram, which like i said the problem remains without, and since iv also just reinstalled windows 7, iv disconnected and reconnected all the psu wires

[SpikeSoprano]

Just because the psu is new dose not mean it is not faulty, I think the first thing I would do is put in a known good psu especially since the problem started with the new psu.<IMG class=bbc_emoticon alt= src="http://forums.overcl...whistling.gif">

[davemonkey]

did the problem occur after installing the new psu? if so try another psu as that is logically the problem cause !

[hornybluecow]

I'm going to go with Waco and say you just need to bump the voltage up (or down depending on the ram). If it started happening after you got a new PSU than the MB probably reset its bios.

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

Hey guys, I increased the memory voltage to 1.7v which is wat my ram shud be, it was set to auto at 1.5v, running memtest now, 110% coverage and hasnt frozen yet, hopefully that was the issue, time will tell, quick question though like i said I hav 2 x 2gb which are the 1.7v and I have 1 x 4gb which has the same brand, mhz and timing, however the 4gb is 1.5v not 1.7v, is it okay to hav the 4gb installed if my memory is voltaged at 1.7v??

[Waco]

It'll be fine.

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

Appreciate the help, hopefully will stay stable now, one more small problem if you guys wudnt mind helpin me, 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.
