Is there any problems doing BIOS upgrades? I have a Dell 4600 that is about 2 years old. I was having some problems, and the tech guy told me that I need to update the BIOS. You know, any time I do something like this, I get the heebie jeebies. This is the kind of stuff that is way over my head, and if anything was to happen, I wouldn't even know where to start. There is an upgrade available, and I have downloaded it, just not run it yet. Any thoughts...?? TIA!! Wanna kill these ads? We can help!
