PSU issue?

[v3nes]

My computer had blue screen error with error code 0x0000009F (DRIVER_POWER_STATE_FAILURE). Is it a PSU issue? After blue screen I have turned off my computer then I tried to run it again and I couldn't because CPU LED was red. Then I took all of atx 24-pin connector and 8 pin connector and connected again. I also reconnected pcie connector. After that my GPU LED was red. I did one more restart and my computer finally was running but now I'm having errors many programs won't run after startup.

I have format my computer one week ago so I had only few programs installed. My graphic driver was up to date and bios too.

My psu is corsair tx 850w
mobo : asus crosshair iv formula
cpu: phenom II x6
ram: corsair dominator 2x4GB
gpu: xfx hd 6850

// by the way I have noticed that there is missing one cable from my atx 24 pin connector. I mean there is no pin in the connector coming from power supply

It is pin #20. I found out that it is optional but can i cause some problems?

This error can occur because of a device driver, but it can also occur because of a file system filter driver (for example, a driver that is installed by an antivirus, remote control, or backup program).

To isolate the driver that is causing the error, follow these steps:
1.Check to make sure that your computer and all installed devices are on the Hardware Compatibility List (HCL). You can view the HCL at the following Microsoft Web site:
http://www.microsoft.com/whdc/hcl/default.mspx (http://www.microsoft.com/whdc/hcl/default.mspx)
2.Check for drivers that are not designed for use with Windows. You can use the Sigverif.exe tool to do this. For information about how to use the Sigverif tool, refer to the following article in the Microsoft Knowledge Base:
308514 (http://support.microsoft.com/kb/308514/EN-US/ ) HOW TO: Verify Unsigned Device Drivers in Windows XP
3.Check for driver updates that may be available for your hardware.
4.Update any software that uses filter drivers (for example, antivirus, remote control, and backup software).
5.Remove any non-critical devices and software to help isolate the device or software that is causing the error.
6.Install Windows in a new folder. Add drivers one by one, and restart the computer after each addition, to try to locate the driver that is causing the error.

Pin 20 was the -5V rail required for old AT boards and expansion cards. Nothing your system would ever use.

Reset CMOS for kicks and giggles. 0x9F could be a lot of things, maybe some drivers are going mad.

A minidump of the BSOD could help. Make sure they're enabled (Control Panel -> System -> Advanced System Settings -> Startup and Recovery -> Write Debugging Information -> Small Memory Dump (256kb)) and then, copy the latest one from C:/Windows/Minidump.

seems like a failure somewhere but hard to pin down based on this info. I would unplug your system and let everything drain out, remove the cmos battery and reset, and then do a fresh windows install.
