I always keep upgrading this machine, but it still fails at some point, I also fully wiped hard drive and installed windows 7 few weeks ago, it worked ok (but not great) for thous few weeks and now it's same old story...
*PROBLEM
-random screen freeze for 1-4 sec when I'm typing, playing games (mostly League of Legends) or opening images, documents or audio files.
-screen becomes unclickable for few seconds when surfing internet (I'm using only Firefox)
-movies freeze for short period oftime (always about 8sec freeze 6-9 times in 90minutes movie, video files aren't damaged, it freezes randomly)
-recycle bin doesn't want to open, opens 6-10seconds after clicking on it and deleting 1MB files takes way too long (6-30seconds) same happened with win XP
-TOTAL FREEZE (while gaming only), screen freezes and you can see many red, green and blue dots on it, sound starts to buzz, keyboard and mouse don't respond at all.
*SYSTEM SPECS
Intel Core 2 Quad Q9450
GeForce 8800 GTX
ASUSTek P5G41-M LX Motherboard
Corsair dual ram 2gbx2gb=3.5gb
2 hard drives 250gb and 2000gb (2tb are split to 4 partitions, one is broken)
and XFX Pro 550W PSU
*Sensors from SIW
processor 40-55 C
video card 70-80 C
250GB HDD 40 C
2TB HDD 36 C
*Soft
Windows 7 Home Premium SP 1 32bit
ESET NOD32 Antivirus 6

I also ran Seatools from spunk.funk's signature or 250GB HDD (system hard drive) long and short tests passed.
Thanks.

video card 70-80 C

Freezing is caused by overheating or a failing PSU. Is the Video card temperature taken while under load (game play) or when it's idle? If at game play, that is normal, but if it is taken when the computer is idle, that would be a problem.
Try running the computer in a clean boot and see how that goes.

I wouldn't count the PSU out just yet. XFX makes a fine and strong PSU.

Hi Infernalryo,

Check the EventViewer and see if you get any errors. Try repairing the system files and see if that helps. Open up the command prompt and type in "sfc /scannow" without the quotes.

Hope everything works out well for you.

I took this screenshot at clean boot

I also read this What should average temperatures of an 8800 GTX be @ idle and load? - Yahoo! Answers (should I try that rivatuner or something else to increase fan speed?)

P.S.
yesterday I cleaned my pc from dust and replaced thermal grease on cpu and gpu, cpu temperature dropped from 70C to 46~C; gpu temps dropped about 5 C. Is it possible that I damaged something while running on high temps?


To DBCooper
I tried to write sfc /scannow and sfc, small black window pops for less then a second and disappears.

Your temperatures are now good. But Your +12V line of your PSU is way below where it should be, which should be closer to 12V.
Boot into Setup (Bios) go to PC Health or some such and check the +12V line there. If it if it is below 12V by more then .5 degrees, you have a failing PSU

 

[Infernalryo]

you guys always blame psu... my friend is using same fxf 550W psu with 8.59 V on +12V and her pc works as a charm, what can you say for that?

P.S.
I fixed this freezing problem by simply removing 2TB hard drive, now pc loads least 5 times faster and doesn't lag at all.

The evidence is in your post +12v is running at 10.98 and your friend is going to have a problem if your reporting her 12v as this low but of course you know best, hope you have plenty of cash put away as you will need it to replace the hardware that will get taken out when the psu goes south

Think of it this way. You have an electric dryer that runs on 220v if you try plugging it into a 110 115v outlet (Which in reality would not fit) the dryer will not turn on because there is not enough volts. A CPU if not running off of 11.98v or 12+ will try to suck more power from the PSU so it can run smooth, and sometimes cause the cpu to overheat. Since your 12+ v rail is low that will cause your pc run slow, in the end will damage your CPU and or GPU, and motherboard.


Get the PSU tested at a trusted computer repair shop. If the 12+v does not generate at least 11.90v volts or more get a RTM on the PSU.

a year ago I had cheap 550W psu and I was told to buy top quality psu, so I did, in fact I bought 2 exact same psu. (XFX 550W)
Tyree -
"SeaSonic-XFX-Corsair (not the CX or GS Series) are top quality PSU's."

that's why I don't want to believe they're failing, both computers are running with asus motherboards, maybe thous are failing -.-
but still, Voltages ware only checked on SIW, I should look at bios.

P.S.
both PSU still has warranty, can I replace then if 12V runs lower then it should?

Thanks.

I would you can check with this Speccy - System Information - Free Download and this CPUID - System & hardware benchmark, monitoring, reporting
and of course the bios as it should be the most reliable if it is the same rma
