Windows 7: Windows 7 blank screen after waking up from sleep mode

Hello,



After putting my computer into sleep mode last night, I was unable to get it to boot into windows this morning. When i pressed the power buttong, everything turn on and working (all fans are functional, gpu power led is on, all hard drives & cd drives are functional. But the problem is, the screen to my monitor is blank. I also noticed that my usb aren't working (mouse connection light isn't on). I tried a soft power off by holding down the power button but no luck. The system does not turn off no matter how long I hold it. The only way to turn it off is by pulling the power supply cord or turning the power supply switch off.

My pc build:

• AMD FX-6300 3.5GHz Socket AM3+ 6 core processor
• ASUS ENGTX 560 DCII OC/2DI/1GD5 Geforce GTX 560
• ASUS M5A97 LE R2.0 Motherboard
• COOLMAX ZU-700B 700W ATX 12V Power Supply
• G.SKILL Ripjaws X Series 8GB (2x4GB) 240-pin DDR 3 SDRAM 2133 (PC3 17000)
• Prolimatech PRO Panther 120mm CPU Cooler
• NZXT Phantom PHAN-001RD case

THE PROBLEM: Computer turn on with everything running as usual, but shows blank screen on monitor. Cannot soft power off by pressing power button.

Things I tried:

• Clear CMOS by removing battery and switching pins
• Running with 1 4GB RAM instead of 2, move the ram around the slots & alternate which Ram is used.
• Check my monitor by testing it with another computer
• Tried pulling the PS plug and holding the computer power button for 1 min
• Test the GPU with another computer & it runs fine
• I tried removing all USB and excess drive and booting up with only the essential (GPU, CPU, 1 HD, 1 Ram)
• Checked all connection between Motherboard and Power supply
• Checked all connection within the PC

From my research, I noticed that many people are saying that there is something to do with the ASUS motherboard bios that need to be updated. And since I cannot even get into the boot screen, I can't update the bios. Please let me know if there is anything I can do/try to troubleshoot the problem.

Thank you so much,

Kevin
