I was experimenting with my brothers desktop. It seemed like it was running well. Still one of his drives an SATA Samsung wasn't displaying it's icon on the my computer screen that shows you which devices are attached. Either he accidently shorted the drive cause he refused to use a surge suppressor. Still the main drive worked o.k. Sadly his desktop was purchased used. So the seller had no recovery disks or an original Vista Pro operating system disk in the event the files became corrupt. I recall his system started having problems after I installed HandBrake to convert video to mp4. I also installed DVD43 to decrypt movie discs. I'm not sure if those warez were compatible with Vista. My brother had installed an EVGA 8800 gtx PCI-e graphics which I updated the drivers for it. He mainly wanted it for gaming and editing video. I had read that updating the bios chipset drivers could increase performance and eliminate hardware incompatibilities. I think his OS was an OEM version which sucks. Finally using my neighbors Wi-Fi I went to the chipset maker to update his motherboard chipset drivers and or bios update or firmware i'm confused. The site had an online updater to assist with the install. The motherboard developer was MSI so I went directly to their site. I knew there was risk updating the firmware, but I decided to take the risk. It started updating it automatically backed up the current bios firmware. Then cautioned to proceed with the install. It then went into a very awkward GUI screen the program initiated. After that happened all functionality was lost no way to exit. Some status bar was filling up. So I let it run it's course for several hours. I noticed on-screen some cheap colored bars, some program text and the status bar seemed like it froze up. I wasn't sure if it was still connected to the wifi network. If my neighbor turned off his router or the adapter was still communicating. Reason why I tried this method of updating. Was because my brothers PC lacked a fully functional floppy drive. There was no floppy drive installed. I somehow felt that if I shutdown the PC it would be bricked. I was right in bricked no video or post messages or DOS like screens. I could turn it on but not shut it down. I had to switch the power supply main switch to off. So then I thought would replacing the mother board with the exact same model and connecting the hard drive and other components allow the PC to boot into Windows Vista? or can the bios chip be reprogrammed? The board no longer is sold by MSI it's a P965 Neo MS 7235 v 1.0 Is it any easy task replacing the seated bios chip? And if I managed to replaced or have installed by a skilled technician would the OS recognize the motherboard and bootup? Since it's an OEM it could detect the chip and unauthorize access unless someone hacked the system. That I could never do myself.
