System is very slow after installing a new graphic card

Hello

Last Friday i installed a new graphic card, Asus EAH4870. Since the system is eratic and one ine a while, very slow

- What can I use to test some parameters?
- Could it be cause by a temperature increase?
- Power supply

_ did test inside temp and voltage with Asus software

I got a guinine version, all upgrade are done on a regular basis
Browser: Chrome
Win 7 64 pro
6 gb memory
Drives has been tested, defragmented

I use
- Iolo System Mechanic
- CCleaner
- Kasperskyt 2011

For an unknown reason, I don't have any restore point

Any help appreciated

Martin

What power supply do you have? Did the new card replace an existing one or is this a completely new addition to your system? You should easily be able to find GPU temperature monitor gadgets for Windows 7, or maybe GPU-Z can help you track down the problem.
Did you also make sure to uninstall existing video drivers and shut the PC down without rebooting before you plugged in the new card?

As Carazon pointed out, it could be your PSU. What is the recommend minimum PSU wattage from vendor. If not enough power from PSU, this will cause problems. Have you downloaded the latest drivers from AMD? Check these out and then will go from there.

It could be an overheating issue too, check the fan area and card in general to make sure it's clean from lent and dust and any debris that might be stuck some where inside. Check with speed-fan or SIW, both are free, to see what temps your card is running at. You can also check with in CCC panel.

Hello Bassfisher

What is a CCC panel ?
- I will clean with a air can my CPU fin
- Power supply suggested: 550W Mine is 600... could be on the limit
- I will re-check for the last updated file. It should be the one since i just installed it

I used them for the last two years. And i never had a system so stabled before my graphic card update. So I would keep an eye, but I suspect other interference somewhere

I too used ccleaner for many years and system mechanic when I had a geforce 3. Dumped them after they proved to be more trouble than they're worth. Hope you find the cause if it is something else.

OK, I will keep that in my mind. Do you use other software to maintain stability or you leave Windows 7 do the job.

I also use CCleaner to cancel or remove installed software

What I have done so far...

I cleaned a bit the CPU heatsink , Removed my PC slide panel and close down my PC for the night. Since this morning, system look OK.

I suspect a limit power supply. My actual one is rated at 600w. Graphic card minimum suggested is 550w. Also, I will try to reduce the heat more efficiently with a dust cleanup and maybe another fan

To be follow....

You should be ok with your current PSU.

When installing a new GPU, you first should un-install current/old graphics driver. The easiest way is to un-install is from the device manager. Here's a link from AMD how to go about it.
20870InstallGuideforATIHardware&Drivers


When you physically install the new GPU and boot up the system, you should have loaded in the cd/dvd bay the provided install disc which has the software (CCC panel) and driver on it. Or go to the vendors website and get the latest version. Just putting the card in and letting windows use the generic drivers is a really bad idea. Here's a link for the latest AMD drivers for your card.

Note: Kaspersky AV is known to cause BSOD's and crashes.
