Hi, after a failure in my power supply my Asus V7100 Geforce 2 MX only works with 2D but freezes in 1 to 60 seconds when I start a 3D game or benchmark. (the power failure also destroyed the scanner adaptercard [see below in the system description] and the quantum bigfoot HDD stopped working until I changed the power supply!) I changed the power supply to a 350W Levicom blackline and the system runs fine with my old 16 MB TNT card at 733 MHz. Before the power supply failure the geforce 2 MX worked in the system for about 2 years and in last january I upgraded my old pentium2 350@392 MHz (112 MHz FSB) with help of a adaptercard to a coppermine celeron with 733 MHz. Even overclocked to 1232 MHz (112 MHz FSB) the celeron system worked without any problems with the geforce 2 MX at about 40°C processor temperature at 100% cpu use. After the power failure: The geforce 2 MX works normally at boot up and under windows until I start any 3D game/benchmark such as 3D Mark 2000. The later benchmark worked without problems before the failure. I also tried my old pentium2 but the problem is the same. Using my old TNT card 3D games/benchmarks run with a processor clock of the original 733 MHz (66 MHz FSB) but also hang up when overclocked to 75, 83, 100, 103 or 112 MHz FSB. The TNT card worked with 112 MHz FSB before I installed the geforce 2 MX Anyone with an idea where the problem/s may be ???? Here's an description of my system as it worked before the power failure: My P2B system: -------------- As you will see the system is full with no more place for anything (6x 5,25"; 2x 3,5" slots und 3 additional place for 3 HDD's; 1x AGP; 4x PCI; 3x ISA - of which 1x PCI/ISA is shared; all slots are used!!!): Bigtower ASUS P2B Board Rev. 1.04 Bios 1014 beta 03 Celeron 733 at 1232 MHz (Coppermine; FCPGA) (before Pentium II 350 at 392 MHz) 256 MB PC133 SD Ram (1x 128 MB; 2x 64 MB; different brands) AGP: Geforce 2 MX PCI1: Tekram SCSI Controller PCI2: Sound Blaster 64 PCI PCI3: Hauppauge Win/TV PCI4: 10/100 MBit Network Card ISA1: (shared mit PCI4) ISA2: Sound Blaster 16 (CT2290 with IDE controller onboard; see IDE3) ISA3: Controller card for ESCOM Scanner 1,44 MB HD Diskdrive 720 KB DD Diskdrive SCSI: Teac CD-532S 32x CD-Rom / Teac CD-R55S 4x/12x CD-Writer (4x CD-R / 12x read; no RW) IDE1: Maxtor 30,7 GB / IBM 6,4 GB HDD's IDE2: Quantum Bigfoot 2,5 GB HDD (!!! 5,25" !!!) / Toshiba SD-M 1502 DVD-Rom IDE3: Maxtor 515 MB or Western Digital 4,3 GB HDD (changable) / Aztech 6x CD-Rom (the 4,3 GB HDD has some strange mechanic error but is still working if not used permanently) Thanks for any suggestions, Free Weasel

Pull your ramstick out and take it to a shop and have it tested. I had the identical problems to you and it drove me crazy, then I discovered that some of the upper address blocks in the memory were bad. Under normal load it didn't show up, only when high stress was put on it (game rendering!) and then when the CPU tried to addess the upper blocks it crashed, froze, etc. Also, if I read your post right, it seems both your video cards give you probs after your PS burnout. The spike may have damaged your RAMstick and/or Video Card as well, since it hurt other things in the box.

Thanks Ranchhand, should have thought of it myself !!! As I have 3 Ram sticks first I try them out seperately and I can also try one stick from my Athlon system. But today I don't think I can steal the time so it takes a day or two. I hope it's only one of my 64 MB sticks !!!!

Run the memtest but everything worked fine! Following an idea I reinstalled the graphiccard and set all RAM and graphic options in the bios to the lowest/slowest settings and then everything worked again. I know it worked at the higher settings before so I still don't know what happened but it's running again and that's the important thing! Thanks for your help !!!
