hey, i've got this problem where my computer crashes this is my story

i bought a new computer last month and built it myself, it worked fine untill i bought a new cpu fan which is this one
Canada Computers - Cooling > CPU Cooling : Thermaltake CL-P0466 CPU Cooler for Intel Socket 1366/1156/775 & AMD 64 754/939 & AM2+.

at the same time i installed this fan i also installed a 120mm one... which didn't have enough room to fit so i just pushed it in there as hard as i could... thats when the crashing began.
i cut the 120mm fan so that it would fit in my computer without putting any pressure on my cpu fan, but the crashes continued..

i took out the cpu and found there was too much thermal paste on it. (my stupidity),, so i got both the motherboard and the cpu RMA
after i got both new parts the crashes were less frequent but still occurred. also the computer is running much slower then it was when i first got it, which was before i got the new cpu fan and when everything was running fine with no crashes...

i even tried changing back to stock cpu fan and the crashes continued..
i know its not the motherboard for sure and that its not the cpu cause i already got new ones from RMA

the crashes don't show any blue screen, the computer just freezes where it is without rebooting or anything.. and my sound just keeps repeating the same sound when it stalls.

it stalls whenever it wants to, but sometimes if i really want to try to make it stall i must download torrents, install 2 games at once, and open like 30 websites, thats when it crashes for sure. i know its not my windows or software, cause i installed windows 32x and 64x with vista and windows 7 and i still get the crashes.

i can't find anything wrong with my cpu.. but i was looking up psu voltage recently and my readings from speedfan were kinda weird... i need to know if this is normal

my vcore1 is 0.88V
vcore2 = 1.57v
+3.3v = 3.36v
+5v = 5.08
this is where its kinda weird, not sure if this is normal
+12v = 1.27v ( this one keeps going up and down wildly)
-12v = -0.92v
-5v = -8.67v
+5v = 3.63v
vbat= 3.14v

this is my computer specs

i got a i5
motherboard p55m-ud2 gigabyte
corsair 750w
i have 8 gig of ram 1333 mhz 2x2gb kit patriot dual channel kit two of those...
2x sata lg dvd rw
nvidia gtx 260 geforce
antec 900 case and i added 2 extra 120mm fans as well
seagate 1tb 7200.12
cpu fan is a Canada Computers - Cooling > CPU Cooling : Thermaltake CL-P0466 CPU Cooler for Intel Socket 1366/1156/775 & AMD 64 754/939 & AM2+.

and i also have two extra 120mm fans installed inside.

PSU model? Memory timings and speed set correctly? Temps?

now i just ran the computer on default mode in the bios and still have problems with crashes even with the voltage you suggested.

well i rechecked the cpu fan on the cpu the arctic silver i put is perfect not too much not too little...

these are my readings from bios
vcore= 1.236v
ddr15v= 1.568v
+5v = 5.080v
+12v = 12.365v
system temp 25c
cpu temp 25c

recently a new problem occurred where when i turn off my computer, the next second it will automatically turn back on, this occurred a few times, but now it stopped, i was wondering if it might be a problem with my psu

i ran prime 95 with 1 stick of ram and it continued running for about 12 hours no errors, whenever i have 2 or more sticks of ram it will begin to error. also if i ever use more then 1 stick it will always stall, after i tried more prime 95 tests and agian the errors came up randomly, these errors were never happening at one certain core and always at a different time into the test, one test all three cores had errors at the same time. and prime 95 i noticed is always having trouble maintaining 100% with all cores usually its 1 or 2 cores that don't work and then a minute later its the other two cores that don't work

but i know its not the cpu or the motherboard cause i just got both of them RMA

i ran the ram test and i did it with 1 stick and i passed, then i did it with two and the computer just restarted after 10 secs into the test, i ran it agian and the result was the same.
then i ran it with 4 sticks and the computer just didn't move... never proccessed anything, but i could tell that it didn't stall cause it was still flashing...

these are my ram sticks
patriot g series 4gb pc3 10666 1333

i just realized my ram is made for AMD’s socket AM3

does that matter since im using intel gigabyte?

[Carbon]

Depends. If it's 1.65V+ RAM, it could fry the processor. If not, it shouldn't matter as long as it's set correctly.

[bong]

its 1.5v...
i don't understand whats wrong then... only when i use 1 stick can i pass the ram tests... if i use more then 1 stick then the computer will reset or not even be able to start the ram test.

[Carbon]

Sounds like the RAM isn't actually set at 1.5V in the BIOS, or the timings are wrong.

[bong]

yeah its not... its at 1.58 for some reason... what is timings? how do i set that

[Carbon]

Timings are the latency of the memory, often represented as four numbers with dashes. (5-5-5-15) Should be in your BIOS.

[bong]

i just set all the voltages properly and timings too.. still the same result...
