I got the old desktop from my husband after he bought a new gaming pc. He reused the old PSU, so I bought a new Corsair CX600 PSU. After installing the PSU into the desktop, we tested it and every thing went fine, so we brought the desktop upstairs and installed it on its new location. But when we started it up again it went off immediately. We could smell the smell of plastic, but we could not find its source. We got all the components disconnected but not the CPU and CPU fan. We smelled all the components to find the source, but every component smelled about the same. Now the motherboard does not respond on anything anymore and the CR4K2 led is burning. We looked online but we could not find an explaination nor solution. The computer has an Foxconn CS1XEM2AA motherboard a AMD Athlon 6400+ CPU a XFX GeForce 9800+ xxx black edition GPU 2 Team Xtreem DDR2 800 MHz 1 GB RAM 2 HDD in rate0 a DVD player/burner and a new Corsair CX600 PSU (600Watt) I hope someone can help me with this.

Check display without cabinet maybe motherboard getting short with cabinet and try new Power supply check all the power supply connectors connected or not .

Almost any standard ATX psu will fit this model, 86mm x 150 mm x 140 mm I would think. (PSUs come in standard sizes, most are ATX with depths into the case of 140mm upwards. Your old PSU s 140mm deep, so I should get one that also that deep. Higher powered ones can be can be as deep as 180 mm which wouldn't fit in your computer). It would be better if you bought a good brand one such as Antec, Corsair Silverstone, Seasonic, even an a Zalman or Akasa to name but a few, of at least equivalent power (it does not matter if it is a higher rated power, your computer will only take what it needs). Be certain that the PSU has enough of the correct type of connectors for your PC - Molex 4 pin power, minimolex for floppy if you use that, and SATApower if you have those, and 4 pin (I think for your pc) "P4" connector for your mainboard/CPU, and a 20+4 (20 pin with detachable 4 pin section for 24 pin m/b) pin motherboard connector. Be certain that it will accept the correct input voltage for your location (many will accept 90-240V ac now). You might try to get a second hand one.

Try removing the old ones and it should work. The old ram would just slow you new ram down anyways.

***I'm pretty sure your power supply is dead, you will either #1 take to repair shop or #2 replace it yourself.

The Best Value 550W Gold PSU 12cm 24-Pin 550 PSU is compatible.

The Corsair Memory 550W VX PSU is compatible and Corsair is an excellent brand, but you may have an issue locating the excess power connectors inside the case.

The Xilence XP480-12R Power 480W Quiet PSU would be fine, providiing the "hard drive connectors:2', are 4-pin Molex connectors.

you have a board supply wire wrong if getting same messages with the 1000w psu- or a bad board

Faces downwards

check the bios settings...if onboard video is enabled or not....
if this does not solve the problem...try to replace the psu...with a good psu from corsair...
this might help...post your further queries

the 9600GSO uses arounf 250 watts under load. While I cannot fing exact spec for the HP PSU I would be surprised if it were more that 350W. Is there any indication on the case or can you open the case up and look at the PSU?

9600 GSO Power

You need somthing in the order of 450W or greater. Get an Enermax, Corsair or other good quality PSU.

unplug power
re-seat video card
plug power - turn on all
windows comes up - else try another video card.
