Question

I pieced together this pc from older ones I upgraded or just generally toyed around with after my last pc got stollen now this mother board seems to have some problems but I dont want to have to pay 30 or 40 bucks for a bios update and theres some drivers that are obviously outa date or bad and I was just thinking with something like this there should be a way to get the bios update and drivers i need for this situation for free am I wrong? Do I absolutely have to subscribe to some company or buy some software that Ill only use this once because Ill be buying a new pc pretty soon or rather building a new one. Any help would be greatly appreciatedHere is the information I have on the system Im running and it has a 20 gig hd and a 512mb ram and cdr/dvd drive:Computer name: HOME Your Ticket #: 37JRJLK BIOS Type: Phoenix BIOS Date: August 12th 2000 BIOS ID: 31511.STD.0000.D.0008121626 BIOS OEM: Unknown Chipset: Intel Whitney 82810 rev 3 SuperIO: ITE 8702F rev 5 at port 002E Manufacturer: Trigem Computer, Inc.
