I got my 5850 yesterday, connected it properly etc. Thing is when i goto boot my machine the lights come on but the monitor doesnt. You can hear the graphics card fan sort of "revving" (like a car revving basically) and each rev seems to restart the machine, after about 6-7 revs the monitor comes on and everythings ok. Just wondering if i can sort out the boot problem, was thinking maybe its struggling to get power at the start?

5850 Boot Problem
- Thread starter runt
- Start date
you have the exact same problem as me, and so far no one has come up with any answers so im leaning more towards its a dodgy card,
- cant be a driver issue
- cant be bios as ive checked all settings and people are getting this problem with different mobos
- cant be power i have 600w psu
i dont have a clue
what specs u running?

From what ive read its either a PSU problem or Ram.
Im thinking it could be my PSU?

This PSU only has 31A combined across the 12V rail. I though the 5850 needed about 35-37A+ so this could be cutting it fine. Some more experienced forum members could advise you further though.
i had to rma one of my 5870s because of this same reason,loads of ppl have had the same issues and nobody seems to have any answers why this happens.
And if definitely wasnt a ram or psu issue as the company accepted my rma and issued a replacement card all is ok now.

I dont think its my RAM since it works fine with my old card. I think its either my CPU (going to reset the cmos when i get home) Or my PSU.
Could you recommend me a PSU that has enough room for crossfired 5850's?
Also what about the adapters (in my previous post)

I have the same problem, had RMA'd my sapphire 5850, but the tests came back fine, it booted up and ran games and the benchemarks on their test system. Got it back now, still doing the same, might have to upgrade PSU, which is corsair 520HX along with msi K9A mainboard with the latest bios (1.8), and looking @ http://ati.amd.com/products/certified/powersupplies.html#pstop think might have to.

Got to be a problem with them, dropping like flies these cards.
Really? I hadn't seen many reports of them dropping like flies. I am aware of their problems (being new tech and such) but have missed reports of them fizzling out
.My asus is doing me quite proud bar the irritating flickering issue with my second monitor when just on the desktop if I overclock it.

Are you meant to connect both the molexs on each adapter (so a total of 4 molexs connected?)
Yes, id plug 2x molex into that.

Theres loads on here, and other forums as well, with this as the main problem, no post screen, fan 100%, and taking about 5-6+ restarts to get them going, luckily mines working fine so far (touches head (for wood
)).

My 5870 worked fine for a week then started giving me boot problems.
