Hi,
I recently upgraded my pc and those are the changes i made
Core 2 Duo E7400 2.8 -->Core i5 2500 3.3
Ati radeon hd5770 -->Ati radeon hd6870
4gb ram --->8 gb ram
asus p5qld pro --->asus p8h67-M pro
Everything works fine :thumbsup: except that i sometimes get some flashing pixels or sometimes stay still until i put a window over them (different colors) on desktop(NOT in games) only desktop or when i watch a movie or a video on youtube....i asked the shop i bought the things from and
they told me it might be overheating or need a new psu or monitor..i send pc there to check everything but they told me everything is ok....I have done some tests that are on internet like changing background colour but i see those pixels once at an image and i can see that image 200 times and not get pixels...I can't explain it more specifically :confused: ...I hope i made you understand....any help would be appreciated :help:

Hi KostasPAP
Download Speedfan and install it. Once it's installed, run the program and post here the information it shows. The information I want you to post is the stuff that is circled in the example picture I have attached.
If you are running on a vista machine, please go to where you installed the program and run the program as administrator.

Ok you have a couple of high temp readings and the +12V reading is showing as being very low so a further test needs to be done for comparison http://www.cpuid.com.../hwmonitor.html again post a screenshot of the results.

Ok the high temps are still present and there are a lack of power readings so my first suggestion is that you try a known good PSU, it must be capable of providing good clean stable power for all your system.
Provide us with your present PSU details brand and output please, did you apply the correct amount of TIM when you fitted the CPU , heatsink and fan http://www.geekstogo...rface-material/

See posts #12 and #13 @ http://www.geekstogo...7-call-of-duty/ is this a pure coincidence?
TIM is what keeps your CPU cool, please take the time to read the information at the link I provided so you fully understand its use.
I am going offline now until 1700hrs UK time but if you post back meanwhile someone else may assist you.

Yes ensuring the TIM is adequate is very important.
Good brand choice of PSU and the output gives you plenty of headroom should you wish to upgrade further in the future.

No one at GTG can or will answer you with a Yes or a No to your question, to do so would be both unfair and irresponsible, look back over previous assistance offered and you will find a common denominator http://www.geekstogo...7-call-of-duty/ see post #11 of colleague Starjax to see concerns regarding the PSU.

Without a doubt!

But if...i say if that doesn't solve the problem what is the next step???

First step first, ensure that your TIM is applied correctly and only then connect your new Corsair PSU as to do otherwise will start you back at square one.
