History: Bought tower in 2013. Has worked fine up till end of march 2017.
Noticed PC would not boot. Suspected tv tuner card which only recently installed. Removed and rebooted. System came up OK. Left card out .After a approx a week, went to boot up in the morning- no response. Removed front panel and found broken lead to power LED. Resoldered and tried again. Booted successfully. After approx week died again. Checked front panel connections on case and on Motherboard -all seemed OK. Did PSU test with jumper across 24 pin connector – all voltages seemed in spec.
With 20 pin connector still jumpered left 4 pin in mobo skt and 12v ATX power lead
connected to mobo. Switched on PSU with toggle switch. HDD's initialised , CPU fan and GPU fan fired up + HDD activity LED came on but no boot!
System Specs:
MOBO: Gigabyte GA-B75M-D2v
CPU: Intel i7 – 3770 (LGA-1155)
Ram: 2 banks of Transend 4G 2Rx8 DDR3 1333U
PSU: Widetech Model PS550TM 550W
HDD: Seagate Barracuda 1000Gb SATA . Model No ST1000DM003
GPU: Ge force GT640, 2GB PCI express
Would welcome any other suggestions you can provide.
Thanking You
