I'm having booting problems with the Asus Radeon 5850. This is the second one I try (RMA'd the original..) I have an M2N-sli with a 750wtt power supply with 2 dedicated 6pin power connectors.
Put the new card in and the system refuses to boot-up. A few hits of the re-set button seem to get the pc up and running. BUT the system will not re-boot in subsequent times.
I've re-seated the card. I've checked the power connectors. No beeps just the fan spin up with a DVD seek of some sort which just loops till I hit the reset a few times.
I even removed power off an extra Hard drive plus the floppy drive in order to remove any extra power drain. No success.
The system is stable using my older vidcard....an Nvidia 9800gtx+ also with a dual six pin power connector.
Strange. Is the mobo incompatible?
My whole sys is this:
Athlon 64 x2 6000+
ATI Radeon HD 5850 (unstable boot ) or Nvidia 9800gtx+ ( stable boot )
Creative X-fi pro
230gb hd, 300gb hd, 80gb hd.
750wtt PSU Thermaltake
Windows XP SP3/ Win7 dual boot
Once the PC boots thru the system seems to work fine, ran some benchmarks wiht no issues. Well I'm about to reboot and change the vidcard.
PS After the vidcard swap the computer boots up fine.... I'm very disappointed.
I can't believe the mobo cant provide sufficient power.
