After BIOS recovery from usb flash drive, computer doesn't start. No video output and keyboard with mouse doesn't work. Usb stick's LED blinks for a while. The green and blue LEDs are on. CPU fan is rotating. But nothing else happens.
After boot computer beeps 3 times then pause and everything repeats again. I changed the memory cards, but it doesn't solve the problem. I checked this memory with another computer. It works perfectly. Memory with less frequency doesn't fix it also.
I removed all peripheral devices, tried to use PCIe video card.
To recover BIOS I had MK0067.bio on my USB flash (FAT32 16GB) with removed BIOS CFG jumper (yellow).
Can you give me some advice to solve this?
My configuration:
MB: Intel DQ77cp
Proc: Intel i5 3330
Memory: Kingston kvr16n11/4 (2 pcs.)
BIOS before upgrade: MKQ7710H.86A.0048
BIOS tried to install: MKQ7710H.86A.0067
