The problem:
System keeps turning off randomly after I reassembled it! Had taken it apart to clean it up with an air blower.
The System:
AMD Phenom II X3 720 BE
ECS A790GXM-AD3 (Socket AM3)
Corsair XMS3 DDR3 1333Mhz 4GB Twinkit
HIS Radeon HD 5770 1GB
WD Caviar Green 640GB
ASUS U-65GA 650W PSU
CM690 with three stock fans
GlacialTech F101 CPU Cooler
NoiseBlocker 120mm 2000rpm fan x 2 (on CPU cooler)
NoiseBlocker 140mm 1600rpm fan (exhaust top back CM690)
Stock 120mm CM690 fans on front, side, and rear.
GlacialTech 120mm 900rpm cooler fan being used as a secondary front fan
The Story:
Okay so I'm facing a rather weird problem. I did a thorough cleanup of my desktop which had gathered a lot of dust. I took apart everything from the motherboard, GPU, CPU, Cooler to all the components of the CM690 chassis and used a high pressure air blower to clean everything up! That's pretty much the routine maintenance I do every couple of months.
I also added three new case fans to my CM690 (to work along the stock fans). All three are from Noise Blocker. One is 140mm while the other two were 120mm.
I decided to install the two new 120mm fans on my GlacialTech F101 CPU Cooler and use the stock 120mm fan that came with it as a case fan. So attached the new fans to the cooler rather comfortably and then reassembled my PC. I did have a gut feeling that I may not have applied the the thermal compound correctly because my right hand was shaking too much after prolonged use of that powerful air blower.
Anyways, I assembled everything back like normal and turned on the PC to find that my motherboard's CMOS had been reset. So I go into the BIOS and start to to reconfigure everything when suddenly, the PC turns off. I tried again a couple of times but I couldn't even get it to power on. So I reinserted the RAM modules. The PC did power on now but again shut down when I was about to login into Windows 7.
So then, to trace out the issue, I started taking components out to see what was causing the issue. I removed my discrete HD 5770 and connected the monitor to the integrated HD 3300 on my motherboard. But the system still had the same issue although I was able to get much deep in the OS (was just about to launch coretemp to check if something was overheating).
I tried using one memory module at a time in different slots but that didn't help as well. I disconnected all the fans except one of the CPU cooler's and another on the back of CM690 to see if the fans were somehow causing the issue but the problem still remains.
Now I don't have spare components to try and see what's actually causing the problem and I don't have warranty remaining on anything as well because it has expired on some stuff and void on others due to overclocking.
Can the Issue be related to the power supply? It would be really helpful if someone here can tell me what's wrong with my system because I've given up after trying for hours and am considering throwing away my Computer Engineering degree.
P.S. Sorry if I made any typos cuz I'm posting this from a mobile phone.
