GA 790XTA-UD4 -> Fail to BOOT 7 times of 10 !

[taz100]

USB keyboard, otherwise I cant be in BIOS.

tried underklock cpu and core volt 1.5v and other things, that didnt do any better either.

Are you sure about the beep codes the machine is producing? It is possible that the keyboard is producing the problem.

[taz100]

The beeep code ONLY shows up at same time as GPU goes  100% and monitor Fails to start in boot.....

not the times when Boot up is normal.

[Dark Mantis]

Just check that your CPU cooler is well seated and firm will you?

[taz100]

its a new installed mugen 2 , screwed tight...

[Dark Mantis]

Please make sure that it is not screwed too tight because there have been instances of people tightening up the location mounts on some of these bigger HSF combos and either distorting or even cracking the motherboard lanes.

[taz100]

well,first I did have it kinda loose for 2 days, so it was same as earlier and when I started this Thread I was On STOCK cooling with AMD standard mounting that cant be too tight...

So this change mado nothing better or worse...

[Dark Mantis]

Fair enough! Just best to be aware of the problems that you can face.
