can only boot by pressing mem ok!

i guess so, coz its only 8-9 months old mobo + other bios setting like date/time etc. are stored correctly

took the mobo to repair center with my cpu and ram, and my surprise it booted just fine!!!!!!!!

came back home assembled the pc again and same problem occurs

this time a didnt connect front usb ports, used the stock amd cooler too

also i have one empty standoff slot on my cabby, can it be the reason for this?

test the mobo+cpu+ram+psu by putting those on a table - don't even use the cabinets power button - use mobo's power button/ start pin header instead.

ok, so did what you suggested
but the mobo didnt boot again

man i am fed with this, what to do??????????

^^ have a little more patience.

any chance of testing with some other PSU ?? and did you run the above test without gfx card ??

 

[vishalg]

i have a spare PSU, but thats only 400W

actually my mobo dosent have onboard graphics

^^ so the guys on service center must have tested it some different PSU and gfx card - see if you can borrow a PSu and gfx card from to test and if your bios has some option called video bios / system bios caching disable those.
