HI all,

I used to run a 620w modulair coooler master PSU for my i7 ,gigabyte x58 extreme mobo and 4870x2.
but i recently changed to 2 4890 and a new corsair HX1000 mod psu.all well,the system run verry good for a few days but yesterday when i wanted to boot my gpu fans were at max and the 1,3,and 4 diagnose led on both cards were on.also the debug leds on the mobo give me the code 88.
I cleared cmos,tried booting wit just cpu and minimum of ram like te customer service of gigabyte said.but nothing happend.i also removed the bios battery but i diden't help.

I d'ont know what to do next.......completly out of ideas

Dear Sir,

Thank you for contacting GIGABYTE.
The 88 is unused/reserved code.
Please, When there is no display on your system, please follow these steps:
1- Disconnect the CD-Rom and Hard disk from the MB.
2- Check if the devices are inserted very well (Like CPU, Memory and VGA-card).
3- Try "CLEAR CMOS".
4- Try with other CPU, Memory, VGA-card and power supply.
If still not solved, please contact with your dealer for checking and repairing. Thx!

Best Regards,
