MY computer still runs seemingly fine for all day to day task such as web browsing listening to music and videos. I recently experienced a power outage and computer doesnt run the same anymore. i see it most in high graphical games. i used to get 150 fps in the menus and 100 fps in game now i get 150 in menus and anywhere from 3-60 in game. it seems like it gets worse the more im doing. if im watching a movie it gets lower if im streaming anything it gets lower it almost seems like the more stress on my cpu the worse it gets

5-3570 3.4 GHz
Nvidea 670 GTX
1 TB hard drive
Biostar TZ68K+
2.7 bios
Windows 7
12 Gb RAM
1 32in toshiba hdmi (main)
1 lg 24in dvi (secondary)

i cant for the life of me figure out whats causing this and if its a faulty comp part id like to find out so i can price check it for a new one or see if its still under a warranty

Try Uninstalling the gpu drivers and installing them again to rule out a damaged driver. Run hdtune check your drive smart file for errors.
Run memtest86 from boot disk.



i reformated my comp after i started noticing problems its a reletivly new hard drive and the hdtune found no errors after the reformat i installed the gpu drivers so they should be good memtest had no errors

What psu is currently installed in your system? It could be the psu is damaged and cannot provide stable power under heavy loads

when did you get the bsod? was it when you were gaming? I suspect it could be a faulty psu. do you have another psu to test with?

the only extra psu is like a 250W dinosaur

i was running smite at the time of the second bsod

the first time it was when i tried to switch which moniter was my main sisplay and the second time was when i tried to go from full screen to borderless windowed in Smite

It could also be a gpu problem. Do you have any gpu's laying around?

i had a kinda shitty one but it was starting to give me issues which is why i upgraded and also i couldnt run smite at max settings without getting worse fps then i have now

the only spare part thats even close to on par with my comp is my extra cpu

Can be few reasons (and solutions):

-Driver problem. (Uninstall with DriverSweeper and install latest one)
-Extremely high temps. in GPU or CPU. (Check the fans and remove case side-panel.)
-PSU damaged. (Buy new one with a correct rail wattage)
-GPU damaged. (Warranty or tears.)

I would check in that order.

Hope it helped.

the gpu test showed 40 avg fps and 88 max gpu temp which seems high to me

im prolly gunna go clean out my whole case and posibly turn up my fans

also side note question is upgrading to an i7 gunna be that big of an improvement

if you didnt get any weird artifacts or tears on your screen durirng the test, your gpus okay. No an i7 wouldnt be a big upgrade, especially in games. its only a good upgrade if you do alot o video encoding or work with other specilized softwares. Honestly, just reformat your windows or schdule a chkdsk on your boot drive

¿Did you tried with another PSU and GPU?

All seems a power supply problem with either your GPU or your PSU.
