hi been having this issue for a few days when i turn my computer on most of the time it will power up all the fans, hdd etc. and then beep 20 times in quick succession, this is followed by it rebooting and repeating. it will sometimes boot fine straight into windows. when im in windows it could be fine letting type this out for example but other times it will reboot randomly. A friend of mine told me its likely a problem with the mobo and will need to RMA'd but i dont want to send it back if its another problem
i've ran memtest86+ for 2.5 hours with no problems and im on version f18 (latest bios excluding beta)
hardware been fitted for 8 months with no problems till now, no hardware changes.
ill post my spec below,any help would be appreciated thanks.
