Windows xp drivers for R5 230 Graphics card

Firstly, start your pc in safe mode (f8) on boot up. This will start your pc in vga mode, and hopefully the lines are still there, which will indicate a faulty graphics card, if they aren't it may be a problem driver. If no lines, go to Add/remove programmes and uninstal your graphics driver. Re boot pc then when it finds your card make sure you point Windows to the folder in which you have saved the driver files. The driver should then install, see if any change. You may have to try some older drivers, as Nvidia can be awkward at times. I have had varying problems with Nvidia and replaced with ATI cards with no problems.

So basically you cannot get the pc to POST. Meaning you have just a black screen when you power on the pc, right?

First off, did you attempt to update BIOS before this happened. 90% of the time this is caused by a corrupt bios.

If you did not try to update BIOS before the problem started then try these troubleshooting steps.

1. Full power down. Unplug the power cord from the Power supply. Then hold down the pc power button.
Try to boot the pc.

2. Open the case and reseat the graphics card, hard drive, and RAM.

3. Take out one of the RAM sticks if there is 2 or more. Swap the RAM sticks in different RAM slots.

4. Set the Cmos jumper to clear. Power up the pc. Power down the PC. Set the Cmos jumper back to normal position, power up the PC.

5. Unplug and replug all the power supply cables.

6. Check the powersupply function. Either by a powersupply voltage checker, put the powersupply in a different pc, or try a different powersupply in the problem computer.

Could be bad ram, motherboard, cpu, powersupply, videocard.

If the video card is suspected to be damaged, try it in a other pc (friend's, mom's or dad's, pentagons' ).

if it is bad, there is your answer.
