Corsair VX550 with 550 Watt has 41A at 12V.

Try google for Unknown Device Identifier

Try Radeon HD4770 or HD4670.

Try that vga card in other PC, is it still showing that lines? If it is, prepare to dump your card if it's guarantee time is over.

GF9500 has 32 stream processor and 128-bit memory bandwidth, while GF9600GT has 64 sp and 256-bit memory bandwidth and GF9600GSO has 96 sp and 192-bit memory bandwidth. So bigger RAM doesn't always...

Select PCI-E, save BIOS change, and connect your monitor cable to VGA Card Output

An AMD X2 3800+ won't be powerful enough to be paired with GTX 260 and become a bottleneck in overall system. Even X2 6400+ isn't good enough, try upgrade to Phenom II. But pay attention to your...

Problem Solved, changing in msconfig at boot tab and advanced boot option.

I forget, i use Vista Ultimate SP1 and XP Professional SP3

Hi,

I recently upgraded my CPU from Athlon 64 X2 to Phenom II X4. Everything runs fine, except that Windows Vista only recognized 2 cpus instead of 4 cpus. I run dual boot with Windows XP, and...

What kind of motherboard and RAM do you have? If you're planning to upgrade to Phenom II or Phenom, only few AM2 boards can support it. But in gaming, it's better to use dual-core CPU with higher...

Try clearing CMOS or take out the CMOS battery for minutes, then try power on again.

No problem, only it will run at 266 MHz only...

Re-installing Windows may help... but don't forget to back up your data.

I think it support up to 125 Watt CPU, because I don't see support for Phenom 9950 (140 W)

I think NVidia 9400GT from PNY has one card in PCI form.

No, it's not possible.

Sorry, it's sold

I Agree.

Make sure your 12V+ rail exceed 28A.

Your second motherboard need more power than your first motherboard. And it's a common things that you PSU can't give enough power if it's more than 7 years...try to use newer PSU

Look at the sticker at your PSU. GTX 260 needs more than 31A at 12V+ rails. It doesn't matter what PSU you have, but pay attention at 12V+ rail(s). Sometimes cheapo PSU says it can do 600W max, but...

Power Supply Unit. Check the amp in 12V. Read the sticker on PSU. Seems like ypur PSU can't afford any additional card....

4670 VGA card is good enough when you run it at 1024*768. But if you plan to run your game at higher resolution, find better VGA card like HD4830 or 9600GT

Reinstall newest ATI Catalyst Driver

Normally, when you insert add-on vga card, the mainboard will auto configure itself to add-on card. check your PSU first, maybe it's not powerful enough.

For an $80 card, it's good enough. But make sure it has DDR3 not DDR2.

For $100, best card is Radeon 4670, especially in 1024*768. But if you want to run games smoothly in 1440*900, you need better card, Geforce 9600GT is minimum

Try GeForce 9600GT or Radeon HD3850

Reinstall Catalyst Driver.

Your mainboard can handle any PCIe x16 graphic card, VGA memory type (DDR2, DDR3, or even DDR5) doesn't matter with your mainboard.

Buy an add-on graphic card, your PC has an onboard graphic adapter (Intel GMA 900) which perform below average in 3D Games. At least try GeForce 8400GS or something similar in PCI Express form.

Just plug one of them in your card. How much amp does the 12V give in your PSU? Make sure it is over 20 A... Read it on the PSU Sticker below 12V

If the hybrid SLI is enabled in bios, both onboard and external card will be shown on the device manager. But it only work in Vista, not XP..

Maybe you should try to find GeForce 6200 AGP 128-bit, and tweak it with Riva Tuner.

Sorry, it didn't work. Unplugged battery and power cord, and pressing power button for 30 seconds, didn't work. Any other suggestion will be appreciated, thank you...

Sorry, I can't online for days... I've tried pressing power button for 8 seconds and still didn't work.. unplugging battery and just using power cord, still only most left lamp blinking in orange......

Have you try to clear CMOS?

My friend want me to him installing Windows XP SP2 in his old Tecra 8100. Installation going fine, and just after I left it turn on for about 15 minutes (go to bathroom), it went blank and never turn...
