Today I bought a CoolMaster Extreme Plus 550watt PSU and a Gigabyte 1gb Graphics Card to stick in my current computer which was running
6GB DDR2 memory and a
9600gt Graphics card.
But when I stuck the new power supply and graphics card into the computer it seems like the graphics card isnt getting sufficient amount of power. I took out the 5770 graphics card and put back in the 9600gt and it seems to kinda work. Surely the 550watt PSU would be enough to power the Graphics card and run the computer right?
Yes it should be.
According to most reviews 1 5770 card at load should at least take 100w.
So i think there is something wrong with your psu.
Did you uninstall the old drivers properly?
Most people dont know how to clear the older gpu drivers properly.
Actually I forgot to uninstall the old drivers, I'm trying that now, but usually that doesn't matter much, your usually able to atleast load into windows with the new graphics card and install/uninstall new/old drivers.
yeah cause I can use the old gpu but when i'm using that it has like pixels missing then the screen goes haywire, so I'm guessing its on its way out. but yeah, when I plug the 5770 and plug the power adaptor in, instead of the CPU fan running at full speed it's like runnin at half speed which is giving me the impression the PSU might not be preforming properly? what do you think.. the Motherboard is a Asus P5LP-LE.. its got a PCIE x16 slot so surely the new GPU should work right?
Step 1: Download newest drivers either from Ati.com (for ATI card users) or Nvidia.com (for Nvidia card users). Both card manufacturers put search engine for drivers on their websites, so You just have to choose the model of Your GPU and OS you are working on right now.
Step 2: After You downloaded the drivers, copy them preferably to desktop, this will ensure You that You will have easy access to them later.
Step 3: Download a program called "Driver Sweeper". Install it and make a shortcut on dekstop.
Step 4: Download a program called "Driver Cleaner" Install and make shortcut on desktop.
Step 5: Reboot the computer and press F8 key when You will see first screen after reboot. Press it few times in order to make sure that You will be able to choose the Safe mode option in next step.
Step 6: If You used F8 key in the right moment than You should see a boot menu. It will ask You if You want to start Windows normally, or in the Safe Mode (there are also Safe mode with command prompt and Safe mode with networking options, but both of them are not needed for this operation).
Step 7: Boot Your computer into Safe Mode by choosing Safe Mode option.
Step 8: You are in Safe Mode now. First go to control panel/uninstall and uninstall all Nvidia or ATI programs and drivers.
Step 9: After deinstallation it may ask You for a reboot, but don't do it yet.
Step 10: Use Driver Sweeper, choose Your card manufacturer and search for all files related to Your GPU drivers or software.
Step 11: Repeat the step 10 using Driver Cleaner. Using two programs will make You sure that nothing is left there. Sometimes Driver Cleaner may not find some files which Driver Sweeper will and sometimes DS can't find what DC can. So use both.
Step 12: Now reboot your computer and start windows normally.
Step 13: Install new drivers and software for Your graphics card. Nvidia Forceware has a possibility to perform a Clean Install. Use it. Again it will make You sure that You're doing it right. I don't know if Ati Catalysts have this option too in their install shield but if they do, USE IT.
Step 14: After the process of installation reboot Your computer. You should have new drivers without any traces of old drivers either on Your computer, nor in registry.
If you want to be 100% sure that there is nothing left in the registry, use Registry Cleaner software to search and delete registry parts which are not used anymore, although I think You should be fine without it.
Any questions? Post them. Hope this will help. Cheers.
So its either your psu or gpu.
Could you try your gpu on another psu or vice versa?
Please let me be clear.
So you have a new 5770 gigabyte 1g model yes?And you want to remove the old 9600gt?
You could try both 6pin pci connector on your gpu to see if they work.One may be faulty.
and I'm currently at my cousins house (his computer having the problems) might have to take his computer back to mine so I can test his GPU in my computer and if it works maybe test my PSU in his computer with his GPU. Like the PSU works, but when I plug the lil adaptor in to get "aditional power" the CPU fan runs at half speed and nothing loads up.. So thats whats got me confused.
Breadboard with just motherboard, CPU & HSF, case speaker, and PSU.
Make sure you plug the CPU power cable in. The system will not boot without it.
I always breadboard a new build. It takes only a few minutes, and you know you are putting good parts in the case once you are finished.
You can turn on the PC by momentarily shorting the two pins that the case power switch goes to. You should hear a series of long, single beeps indicating memory problems. Silence indicates a problem with (in most likely order) the PSU, motherboard, or CPU. Remember, at this time, you do not have a graphics card installed so the load on your PSU will be reduced.
If no beeps: Running fans and drives and motherboard LED's do not necessarily indicate a good PSU. In the absence of a single short beep, they also do not indicate that the system is booting.
At this point, you can sort of check the PSU. Try to borrow a known good PSU of around 550 - 600 watts. That will power just about any system with a single GPU. If you cannot do that, use a DMM to measure the voltages. Measure between the colored wires and either chassis ground or the black wires. Yellow wires should be 12 volts. Red wires: +5 volts, orange wires: +3.3 volts, blue wire : -12 volts, violet wire: 5 volts always on. Tolerances are +/- 5% except for the -12 volts which is +/- 10%.
The gray wire is really important. It should go from 0 to +5 volts when you turn the PSU on with the case switch. CPU needs this signal to boot.
A way that might be easier is to use the main power plug. Working from the back of the plug where the wires come out, use a bare paperclip to short between the green wire and one of the neighboring black wires. That will do the same thing with an installed PSU. It is also an easy way to bypass a questionable case power switch.
This checks the PSU under no load conditions, so it is not completely reliable. But if it can not pass this, it is dead. Then repeat the checks with the PSU plugged into the computer to put a load on the PSU.
If the system beeps:
If it looks like the PSU is good, install a memory stick. Boot. Beep pattern should change to one long and several short beeps indicating a missing graphics card.
Silence, long single beeps, or series of short beeps indicate a problem with the memory. If you get short beeps verify that the memory is in the appropriate motherboard slots.
Insert the video card and connect any necessary PCIe power connectors. Boot. At this point, the system should POST successfully (a single short beep). Notice that you do not need keyboard, mouse, monitor, or drives to successfully POST. At this point, if the system doesn't work, it's either the video card or an inadequate PSU. Or rarely - the motherboard's PCIe interface.
Now start connecting the rest of the devices starting with the monitor, then keyboard and mouse, then the rest of the devices, testing after each step. It's possible that you can pass the POST with a defective video card. The POST routines can only check the video interface. It cannot check the internal parts of the video card.
