Sometimes different manufacturers have different beep signals.
getting new Motherboard...
Well, I just bought my first one ever. I know, weird. If you're in the market I got mine from clx gaming, they did a great job and their customer service is great. I don't get nothing out of it, just a good company.This afternoon I started it and got one beep then a black screen...the motherboard is gone...can't boot to boot menu or bios/uefi...after 10 years I can't complain.
Well, I'm assuming you didn't lose any data and I guess you can view this as a good excuse to upgrade.
