here it goes. yesterday, i acidentally kicked my pc while standing up. It froze. I uninstalled the nVidia drivers, because i had some optimised ones. Then when trying to install the original ones, it said the software cannot detect correct drivers for this device etc... i tried several versions etc, so i came to the conclusion of reformatting, since i had everything backed up. so i formatted, and i then install the nvidia drivers, they work. there is a catch though after say 20 mins of running, my PC screen doesn't BSoD, it just reboots, i have the correct settings on the System > advanced > etc... it logs it but just reboots. now, it has crashed 2 time(s) since i have been typing this message... i have saved it onto an RTF to stop me retyping... anyway, my specs: (OH yeah, i also re sitted the DIMMS (2x 512) because it wouldn't boot because i changed something on my bios). Processor: AMD Athlon 64 3500+ Motherboard: Nforce 4 ultra nf4uk8aa-8ekrs Memory: 2x DDR, PC3200 (200 MHz), 512 MBytes, Kingston (single channel) Video card: PNY Geforce 7600GT Pci-e 16x Operating system: Windows XP service pack 2 Sound card: Sound Blaster Audigy 4 (Drivers not installed although onboard is disabled).

A dump was saved in: C:\WINDOWS\Minidump\Mini123105-02.dmp. Please, i am in desperate need of advice and hopefully a fix.
