Computer Stutter; need help

November 17, 2012 at 16:46:24
Specs: Windows Vista, intel quad 2.5/ 8 gigs of ram
My computer is stuttering in both video/audio(includes mouse movements), so basically the whole computer stutters (it also may just pause but not stutter). This occured after I changed the power supply. Before i had a 400w psu now i have a 500w psu in there as the minimum psu for a gtx 460 is 450w. I have also tried to reapply paste on my cpu but that had no effect on the stutter. Can anyone help me remove this stutter?

" This occured after I changed the power supply. "
So you decided to "fix" the cpu?
put the old PS back in and post back if the problem goes away.

"i had a 400w psu now i have a 500w psu"

Without knowing the make/model or specs to either one, we can't tell you if you upgraded or downgraded. What you should have gotten is a quality name brand unit with a single +12v rail of at least 32A, active PFC, 80 plus certified.

" I have also tried to reapply paste on my cpu but that had no effect on the stutter"

Why would you do that? Did you check the CPU temp & find that it was running too hot? Did the temp change after you applied the paste? Did you apply it correctly? The Quad requires the horizintal line method:

Did you check for infection? Have you managed your background apps by running MSCONFIG?

http://www8.ncix.com/products/?sku=... this is the power supply the other one was jsut the original one that came with my acer computer. I put reapplied thermal paste because i thought i may have messed it up when i took off the heatsink to put the PSU in. I just put a layer of paste on both the heatsink and cpu.

Wrong application method Look up your CPU here for details:
http://www.arcticsilver.com/methods...

You purchased a cheap power supply with 72% efficient, not PFC, two 12Volt rails and an apparent faulty voltage regulator.
Return the power supply immediately and purchase a GOOD one.
Look at these:

http://www.newegg.com/Product/Produ...

As mentioned above, you need to purchase a power supply with 80% or greater certified efficiency, a single 12Volt rail, Active PFC, and these have over 40 Amps on the 12Volt rail which will leave you some upgrade room.

Remove your heat sink, clean off all thermal compound from both surfaces with a quality rubbing alcohol (high 95+% Alcohol, 98% preferred, content), and reapply as per above instructions. Too much thermal compound can be an insulator. Applying like frosting a cake can lead to air bubbles which will act like a thermos bottle (insulate). Anytime you remove the heat sink you must remove the thermal compound and reapply.

You have to be a little bit crazy to keep you from going insane.

Certainly a lot better than your original choice.
Look at the reviews by customers on that same model from Newegg:
http://www.newegg.com/Product/Produ...
It shows that there are more people who have had problems with it than the two I listed. In general the reviews are not bad but the number of those who either received one bad or had a problem after 2 years indicates a possible trend to me. For that reason, I would go with a different one. Your choice, of course.
If you need to use the return credit for a new one, try searching for those models I listed on the site you appear to prefer or need to apply that credit.
