Hi,

My Gigabyte F2A85XM-D3H (Socket FM2) board is occasionally recovering using the dual bios from corruption after a cold power down. Also the computer wont start sometimes after an initial power light from the case comes on, the only way to kick start the machine is to cold boot but only if the mains has been turned off and on again first (discharging for 10 secs or turning off the psu hardly works). Also quite often the system wont boot after post it struggles to see any menu (i run GRUB for dual boot and have tried all UEFI and EFI settings known to man). Some times it boots to the menu i can use the machine fine, even a sleep works but a shutdown almost always kills it. Furthermore its started to fail occasionally after a wall socket off and on again as it trys to auto start (as if awaking from sleep ?) and dies again. The PSU i have is total garbage i know this, and it makes a loud crack noise out of the back when turning it on.. it is a corsair builder 400w and cost $37

its all i had around at the time. Do you think its the PSU being stupid or the motherboard not helping the stupid PSU? perhaps the EFI boot and cold start / shutdown problem are two separate things.. i have noticed that a USB 2.0 boots always works but a USB 3.0 Boot doesnt always.

finally i flashed the bios to the latest firmware and that makes it corrupt more (perhaps placebo)

edit* i have repasted and totally rebuilt the machine and its still the same.

That could be your problem right there man. Why are you running a faulty PSU? Corsair CX PSU's are know as a "last resort" PSU. Replace that with a quality unit or you might just take your whole machine with it.

i have just sold my 5850 from another build and intend to buy one of these http://www.bequiet.com/en/powersupply/283

the psu was the only thing i had lying around and i was itching to play with my components + it has annoying cap whine

im typing this from the machine now, i think i may not boot it again until i get myself a decent new PSU

Well my friend, I'll be honest. If you parts crap out, it's 100% your fault because you decided to run everything on a known bad PSU. Sorry but I can't help you anymore since your the cause of your own issues.

Yes it can actually. Damage to rims and suspension. As well as extreme wear on brake's and damage to under carriage. Not to mention almost zero traction which is very important to your car if you want to keep it straight and not slam into a bus full of kids. Go play GTA IV and drive around with flat tires. Almost the same in real life.

Good luck to you and your rig. I hope your PSU doesn't take your system with it. Don't expect any sympathy from OCN if it does.
