For the past few days, I am facing a strange issue. After keeping the PC turned off for long time say overnight and when I turn on, any one of the below issues occur. 1) No display signal from GPU and I will get display only from onboard. In that case, GPU is not detected in the device manager or in the bios. Restarting the PC won't help. But if I shut down the system and turn it ON again, the system shows the display through GPU. ( I performed some experiments during the issue by disconnecting and connecting the display cords and that is how I got the above results).
2) No display, no fans, no lights except Motherboard LED. If I get this issue, I simply disconnect the power cord to PSU and connect it again. It works as usual.
My system specs
Intel Core i5 2400@3.1Ghz
Intel DH67BL board
4GB DDR3 1333Mhz (2GB Kingston 1333Mhz + 2GB Corsair 1333Mhz)
Sapphire ATI Radeon HD7750 1GB GDDR5
1TB HDD
SONY DVD Writer
Corsair VS350W PSU
Additional info : 1)No overclocking
2)Processor,board,HDD,RAM and DVD Writer are 2 years old and had no complaints.Graphics card and PSU are 1 year old. For the past 1 year , system was perfectly working fine without any issues.
3) To ensure enough power is getting from PSU, I ran Prime95 and Furmark to stress CPU and GPU respectively at the same time and found no issues.
4) The ISSUE comes only if I turn on the PC after a long time, say more than 3 hours ( I experimented it)
5) The PC works fine once the PC is shut down from first try and is started again.
The last 2 points (4) and (5) are the clue to the problem. It seems to be a faulty capacitor somewhere in the PSU/ Board /Graphics card. By the way, I am a physicist and that's how I know some electronics stuff.
