As title i'll try keep it short, built my pc in 2009 all has been fine until recently when i installed a corsair h100i. All was fine or so i thought first problem was when on the web using chrome if i open 3 or more tabs only the 3rd tab would freeze i could go back and forth between other tabs but the third would not respond.

Secondly when booting up my pc sometimes windows would not run and i would have to reset and then on the second attempt it would be fine these problems appeared to be random. This morning booted up the pc had it running for about 20 mins then all of a sudden i got the blue screen for the first time ever and i'm running everything on stock settings. On the blue screen at the bottom the code reads *** STOP: 0x0000007E along with 3 other similar codes, at the very bottom it says,

collecting data for crash dump ...
initializing disc for crash dump ...
beginning dump of physical memory.
dumping physical memory to disc: 40

I have no idea what the hell is going on but just now got in from work turned the pc on after 15 mins i lost power to all my usb ports??? So i lost use of my mouse and keyboard, rebooted and all is fine for the moment. I have no idea why or what is going on but i do know this is the first time i had problems and im sure its hardware related... Maybe the motherboard has sustained static damage?

Anyone have any clue to what my problems are and how i can fix it?

Have you tried using a different power supply in there? The extra load from the Corsair could have been too much for it....

I haven't, but i have a Cooler Master UCP Ultimate 900W psu. Is that not powerful enough? Specs are, i7 920 D0, 6 sticks of corsair ram each 2gb 8-8-8-24 1600, 1 wd 120GB hdd 10000rpm for OS and 2 hdd at raid 0 for saving files, ASUS P6T se motherboard. I can't work out what is causing these random problems to happen.

Well, that should be enough power for the system....Have you overclocked anything?

No nothing is overclocked everything is at default settings. When I do prime95 I never get errors but it's unstable it's strange... Something is knackered and I still think the motherboard.

Could ram cause these problems? I can't see it causing my usb ports to loose power though.

I dont think ram would cause that issue, but you can eliminate it as a possibility by putting memtest on a flash drive, then booting from the flash drive....Were any Windows updates recently installed? Occasionally, they can cause more issues than they fix....One in particular (2840149) is known to cause issues, and I recently had to uninstall it from my PC to regain my stability. So run memtest (http://www.memtest.org/), and see if there are any ram issues, then uninstall that Windows update.

ok a few things, first off it sounds like you may have damaged your cpu when you were applying the h100i... did you take the cpu out? if you i want to now take out the cpu and check for any bends in the pins on the motherboard(or cpu if your AMD)... if this is not the case then try taking out every piece in your computer and putting it back in... this may sound crazy but it worked for me once so i recommend you at least try it.

a few things to try,

#1 run dsk check
how to,
-click on computer in your start menu
-right click your main harddrive
-properties
-under tools tab hit the error checking
-check both boxes, automatically fix file system errors and scan for and attempt recovery of bad sectors

#3 Run burnintest,

#4 make sure everythign is hooked up right, just in case you might have nocked out some cables when you were changing your cooler

#5 be sure to check the beeps when you boot up your pc

hope that helps! :D 

note: just wanted to say as well that the thing with your hard drive not being able to read windows happens to me too, but it only happens when i completely cut power to my computer... and one big question did you shock anything on your computer when chaning the parts?

just wanted to check as well you said you have updated all your drivers and your bios right?

bios

also it sounds like you are having cpu errors and a lot of them, to test the stability of your cpu run y-cruncher, if your computer crashes as soon as it starts or it is consistent in crashing after yous start it then it is more than likely your cpu...

Thanks for the advice i done what you said.

Disc check ok no errors
burnintest ok
everything connected how it should be
1 beep on power up (normal) no errors

No didn't shock anything to my knowledge, had anti static wristband on case on a antistatic mat latex gloves and rubber sole shoes.

About an hour ago i was watching a video had nothing else going on and the computer froze the mouse lost power the keyboard didn't or appeared to have power but when i tried to put my caps lock on to see if the light would come on it didn't. The whole thing was locked up until i did a rest.

Any kind of test i do comes back ok or with no errors, but at the same time using it normally say on the net it appears to be unstable for some reason. And now my temps have gone from 35 on idle up to 41 on idle with fans and cooler on the same settings.

Stress tested my cpu came back ok no errors. I haven't flashed my bios or had any driver or windows updates but i did roll back to a previous windows update anyway but has made no difference and it would appear that my pc is getting more unstable every day. I'm going to clear my cmos to see if that will do anything, will i loose all my raid settings and data saved on the raided hdd's?
