I'm running my system for almost 3 years, added a ssd about a years ago, everything is good until recently after windows 7 logo blinking then black out, it took my at least 3 minutes for the windows welcome screen show up. during this 3 minutes black out, there is no signal to the monitor. I decided to upgrade my video card from GTX 260 to 2X R9 280X then re-install the OS and trying to solve the problem. However there are more issues coming up and give me tons of headache so I am hopping to get some help:
 
1. after 2 new video card added and with new installed Win7, the system goes to welcome screen fairly quick. however the mouse and keyboard are not responding. I have to stared at the password box for 5 mins then my mouse and keyboard kicked in. It happened every time when I turn on my computer. I can see the system is still working because the mouse on the password box is slashing, but I cant move it. If I reboot , there is no wait time and both mouse and keyboard function right when I see the welcome screen. There is no driver for keyboard and I delete and install mouse driver but no luck.
 
2. After I reinstall win7, system is very unstable, occasionally blue screen when surfing internet and it mention marvel in the BS description. I install the driver for chipsets, marvel controller and usb3 but BS still bother me. I recently updated the BIOS but still no help...
 
3. Also I noticed when system goes into sleep or hibernate, there is no way to wake it up.... No matter I click the mouse or keyboard, only mouse light up but keyboard and monitor kept dark. I have to make sure it do not fall asleep, or ... hit the restart... This is retarded!
 
4. 2 PCIe slots are to close and I can hear the fan on card 1 is rubbing the card 2 back plate.. seems 2 cards are not perfectly parallel to each other... I have to insert some foam to create some space between two cards...
 
 
I have the genuine Win7 and 8 and I have try both of them for multiply times but no progress. then I have try the RAM, SSD, HDD, video card on another system and they work fine. I am guessing next step I will unplug the HDD and wipe out the SSD and put new OS in again and see if any problem solved..
 
Any suggestions? I deeply appreciated!!!  
 

Hi Chris, Thank you for your input, I have tried NO.1 but the problem keep occuring. and I also called the tech support and I got an similiar answer... I know you guys are very helpful but my problem are kinda unique based on research. I have copied a summary from the computer recovered from BS:
problem event name: BlueScreen   OS version: 6.1.7601.2.1.0.256.1   locale ID: 1033
additional infomation about this problem:   BCCode: 3d   BCP1: FFFFF88004B20FF0   BCP2: 0000000000000000   BCP3: 0000000000000000   BCP4: FFFFF880010C9CC1   OS Version: 6_1_7601   Service Pack: 1_0   Product: 256_1
 
I will try to take a picture about the blue screen itself, it is hard because when I got my camera ready the screen gone and reboot!
 
Thanks!

Hello, thanks for all your help, I got another BS and I take a picture this time. Thanks!

Based on the bluescreen you have a marvel error. If you have any sata cables connected to the red ports disconnect them and make sure your system drive is on a black Intel port. Without any hard drives connected to the red ports see if the error goes away. If it goes away then I suspect the problem to be:
 
1: A bad SATA cable
2: Faulty hard drive
3: A problem with the marvel BIOs setup
