Computer Became Slow After Upgrading Video Card

banzon666 · Nov 10, 2013

After upgrading my video card and PSU from a generic PSU and palit gt 9500 to aerocool strikeX 600w modular and palit gtx 650ti my computer starts slowing down.

I tried installing windows 7 & 8 and installing the drivers of the video card, at first it is running smoothly but after i tried rebooting my system it is very slow to the point that dota2 is running at 1-10fps

my computer specs:
amd phenom ii x6 1090t
asrock 880gm-le
4gb g.skill ripjaw 1600
500gb hdd

what can i do to fix this problem? thanks

overheating might be the issue here, what case do you have? how many fans? can you monitor your temps idle and on load?

Anas Bashar :

i am using hwmonitor to check my temperature...it my cpu stays at an average of 41 and my gpu at 68 during normal use(watching movies,browsing the net) even watching movies using my browser is lagging

i am using i think a generic case, just 1 fan from the side but i do not close the side panel so air could flow freely

Edit: after using palit thundermaster app i could see that my gpu core usage is 99% is it normal?

is your BIOS up to date?
what is the GPU temp while gaming?

banzon666 · Nov 10, 2013

i dont know my gpu temp while playing because i cannot play any game because my fps is around 10-20.
i just have updated my bios and it didn't make any difference.

Anas Bashar · Nov 10, 2013

neglect the bad performance, we just need to know the temps of the GPU under load.

banzon666 · Nov 10, 2013

i have tried reinstalling my OS and every reinstall my pc works fine until i try rebooting which makes my computer very slow and has very low fps

the temp during normal use with google chrome is 66 celsius

banzon666 · Nov 10, 2013

if you are asking GPU temp after starting my computer...it is around 41 celsius

banzon666 · Nov 10, 2013

oh btw as i can see it has 0% power usage is that also normal?

in the palit thunderbird app it shows

core clock: 927mhz
memory clock: 2700mhz
core temp: 66celsius
fan speed: 41%
core voltage:1.087V Base: 1.087V
Power Usage: 0
Core Usage: 99%
Memory Usage: 9%

Have you tried going to the nVidia website and download the latest drivers??? That could be the most simple solution.....Maybe you should try to uninstall all of the graphical drivers. A program that helped me doing this is guru3d. After uninstalling you need to install the newest drivers.
Good luck.

banzon666 · Nov 10, 2013

i have downloaded the latest drivers in the nvidia website which is the 331.65 and reinstalled my drivers.

after reinstalling my computer was smooth and performs well having 50-60fps max settings in dota2 but after reboot it came back to being slow and i'm back to lower than 20fps...

banzon666 · Nov 10, 2013

the solution i am doing for now is reinstalling my drivers and not rebooting my system...i am still searching for a permanent fix

banzon666 · Nov 10, 2013

now that i am using my pc without rebooting(computer working smoothly) i noticed the temperature of my cpu and gpu decreased...

my cpu at idle is around 33Celsius and my gpu is around 40Celsius

while playing dota2 my cpu is at 36Celsius and my gpu is at 46Celsius...

what could cause my computer to work slower and at higher temperature after rebooting?

Anas Bashar · Nov 11, 2013

from what am seeing, the issue is not physical, since it runs normally after you install the OS. i think it is a software issue.
just to be sure, go to BIOS and restore everything to the default settings.

banzon666 · Nov 11, 2013

i have just restored my BIOS to default settings and nothing happened...am i the only one having this problem?

disable the integrated graphics in your bios and in your device manager

Anas Bashar · Nov 11, 2013

ok lest try to use different parts.
1- use your old card
2- use an old HHD if you have one.

Kari · Nov 11, 2013

scan for malware, you might have got a bitcoin miner that activates at the reboot when the drivers are installed...

edit your old card doesnt support opencl but the new one does so the miner wasnt active when you had the old card installed.

banzon666 · Nov 11, 2013

i have disabled the integrated graphics in the bios and device manager but it didn't help.

i dont think i have that malware because i have just freshly installed windows 7 and also tried a freshly installed windows 8.

@Anas what do i do after putting the old card and another HDD?

Anas Bashar · Nov 12, 2013

put the old HDD, boot from the Windows CD/DVD and install a fresh windows 7/8 on it. see how it goes.

banzon666 · Nov 12, 2013

what i have tried is installing my old video card(gt 9500) and its drivers and it works perfectly with my setup(with my gtx650ti).... even after restart my computer(with gt9500) is working fast

Anas Bashar · Nov 12, 2013

sorry, when you said (with my GTX650ti) you meant (with my aerocool strikeX 600w) right?

banzon666 · Nov 12, 2013

yup with installed aerocool strikeX 600w...what i mean is every hardware that i used with my GTX 650ti is what i tried using with my old gt9500 in this testing....and now my computer is working fast even after restart using my gt9500

Anas Bashar · Nov 12, 2013

ok i can say that it is 95% the card is defected, return it while you can.

banzon666 · Nov 12, 2013

ok i will try to return the card and let them test it. thanks for the help everyone

i will keep this thread open for other suggestions (until the shop replace the card) that might help thanks!
