571318 2007-07-22 04:25:00 I just put an athlon XP 2600+ into my computer to replace my 2000+ to make it a bit faster until I get a new computer.

I flashed my BIOS to the latest version (I have a Gigabyte GA-7VA revision 1) but the computer only works when I set the switches to 100 or 133mhz FSB. I don't get any display on my monitor when I use any other setting.

There are 2 switches for the FSB but the manual only tells you about switch 1. On is 100mhz & off is supposed to be auto, but it goes to 133 instead of 166. When I change switch 2 (default is on) my computer doesn't boot.

571319 2007-07-22 04:37:00 Did you try the new CPU before you "flashed the BIOS to the latest version"?

You should install a new version of BIOS code if the new version fixes a problem which occurs on the particular computer.

Why not "flash the BIOS" to the previous version? :D

571320 2007-07-22 04:39:00 Sounds like the other PC here. By default its 266/133.

You can either set it to 266 or 333 (but not 400), I didnt know this till I dl the manual lol. No wonder the mobo was cheap (it was only the mobo, no manual).

But if I set it to 333 and 166 it wont boot either. The same as what youre seeing. I have to take the jumper off the the mobo to get it to boot again.

So, I just left it at 333 and 133. It shows 333 on the post screen.

571321 2007-07-22 04:43:00 the bios my motherboard ships with doesn't support the 2600+ CPU. I checked that before swapping the cpu. If it did, I wouldn't have risked the flash.

Could it be a power problem? I have a 350w PSU, 1 SATA hard drive, 2 IDE hard drives & a Geforce 6600 GT

Edit: probably not a power problem. still does it when I unplug both my IDE hard drives

571322 2007-07-22 05:13:00 I picked up the wrong CPU :blush: It wouldn't work at 166mhz FSB because it is an 1800. I'll probably have more luck with the 2600.

This is what happens when you tidy up spare parts :lol:
