Windows 7: [PLEASE HELP] Serious problem when switching Graphics Card...

Hello!

I have a big issue and Im in need of your expert help.

I have a gtx 260 graphics card and I just bought my little brother a computer that has a Radeon 5770.

Since Im in much need for the HDMI and some other reasons and he's not, I switched our graphics cards.

Everything seemed to work fine at first, I installed the drivers on his computer and the gtx 260 was working fine there. On other hand, when I tried to install the drivers (the screen was huge) on my computer with the Radeon 5770, the computer suddenly froze (it has never done this before).

When I turned it back on I heard a "peep peep peep" sound from the computer after a few seconds and there was no screen on the display. I could hear the harddrive working etc but no graphics.

I then switched places on the HD 5770 card (There were 2 blue contacts that looked the same) and the computer turned on. This time it worked for aprox 20 minutes (with new drivers installed) until the computer suddenly froze again. When I tried turning it back on, I got the beeping sound again and nothing showed up.



Both of the cards seem to work just fine on my brothers computer and I dont think I have any hardware issues on my either since its a pretty good computer that has never caused me any troubles.

Im wondering now, what the problem can be? Im thinking its some software thing, where I need to uninstall old drivers that are interfeering with the new graphic card, or something like that?

I appreciate every help I can get...

The "beeping" you are hearing is a diagnostic code being produced by your motherboard.. What is the exact make and model of your board?

Hello, thank you for your quick reply.

I opened it now and looked, it says P5E64 WS EVOLUTION.

I was unable to locate the codes for your motherboard... If you have your user manual, check if the codes are listed... if you are over clocking, return all values to their default values.. Please fill out your system specs completely... Completely remove the drivers with DriverSweeper, then reinstall them with the latest version ... let us know how it comes out...

I have putt back the GTX260 now and it seems to work fine.

I wrote PSE64 WS Evolution before, it's supposed to be P5E64 WS Evolution.

Full specs:
*Intel Core Quad Q9550 2,83 GHz
*4 GB DDR3 Ram
*P5E64 WS Evolution
*GTX 260 (which im trying to replace with HD Radeon 5770)
*Velociraptor 300 GB 10 000 RPM & 2 600 GB HD's.
*Windows 7 Ultimate - x64 bit.

I've never overclocked.

I'll try that. Should I uninstall the drivers first then putt in the HD Radeon 5770 card?

Some guy said that this might be a "BIOS" issue. I dont think i've ever updated or touched the bios on this computer nor do I know how to do it lol..

If you are going to try to use the Radeon 5770, then use driver sweeper to remove your current drivers, then install the new card...

To change a video card, particularly if you are changing brands, it is very important to follow proper procedure, as follows:

• Go into Start > Control Panel > Remove a Program and uninstall all nVidia programs for the video card. Do PhysX and Stereoscopic 3D first, then the driver. The control panel will uninstall with the driver.
• Now go into Windows Explorer and in the C: drive find the nVidia folder (inside will be Drivers > your driver version) and delete it (the whole folder).
• Run DriverSweeper to uninstall all video remnants.
• Shut down computer and disconnect power.
• Remove the old nVidia card, install the new ATI card. Make sure all auxiliary power connectors are plugged in. Some cards need 2. Read the manual.
• Reconnect the power and boot the computer.
• When it reaches the desktop Windows will find new hardware and will install it's own WDDM1.1 driver. Let it. You will be asked to restart. Do it.
• Once back on the desktop you can now install the ATI driver package for your card.

Hope that helps.

EDIT: on an ASUS motherboard, one short beep followed by 3 short beeps means "no Video detected".

Thank you, I will try this soon and get back to you. Will I need to do any changes in BIOS or update BIOS or anything like that (that ive been told by someone else)? As I understand it, the BIOS is in the motherboard?

No, you should not need to make any BIOS changes unless:

• You made changes to the BIOS previously
• You have and are currently using on-board graphics (from what you have said, you do not)

I would be more concerned about the issues caused by moving the card around in the different slots if you did not properly uninstall it (them) from Windows first.
But running Driver Sweeper should clean up that mess.

Good Luck.

After following your instructions TVeblen, it seems to be working just fine now!

I want to thank you TVeblen and Tews for your help, you saved me alot of money..

much love to you both.. <3
