Hey all. been awhile since I have been here. I just bought a PNY Verto 6800gs, and a Thermaltake TR2-430w PSU to go with it for my computer. I changed the video card, and no problems. I put in the new PSU, and it only gets to check memory, and then freezes. Anyone know what might be the problem? I did read somehwere about some incompatability with psus and some motherboards. Would a bios change help? I checked the PSU with a tester, and everything checks out. I'm running my rig with AMD Athlon XP 3000+, two DVD burners, floppy, one SATA HDD, and one ATA HDD, and finally an internal Zip drive. It runs fine with my old 350w psu, but with the 430w, it freezes. Help please! It's too much of a hassle for me to return the new PSU to Amazon.
