    My desktop, assembled back in December 2011, specs are:
    Gigabyte H61M-S2P-B3 rev1.0
    Intel i7 2600 3.4GHz
    Kingston DDR3 4GB 1333MHz
    Seagate Barracuda 500GB 7200RPM
    Windows 10 x64 Pro updated to latest service pack and other updates
    iBall JSW 250W PSU with the i7272 cabinet
    P/S2 Keyboard, USB Mouse
    2.1 Stereo on VIA 1708S
    Dell S2240L 21.4" Full HD display
    RJ-45 wired ethernet

    The problem:
    Over the past week the computer had gone through these stages.

    1.Some lag and frame drops while playing videos then audio video hangs and PC crashes then,
    2.I disconnected the HDD and restarted but the computer boots to bios and crashes within seconds, restarting again crashes then,
    3.After a few attempts when I start it again there is no display and PC is stuck in boot loop i.e. CPU fan starts-no display-crashes and again CPU starts-no display-crashes.

    I have tried cleaning the RAM and reinserting but step-3 occurs, tried resetting bios no effect again step-3

    Oddly enough, when I disconnect the power and leave it idle for a couple of days then the problem starts with step-2. Also, I don't know how but back panel 2 USB ports out of 4 stopped functioning despite limited usage, sane with the 2 front panel ports.

    What could be the problem and what could be the failing component?

    Kindly guide me to pinpoint the problem.

    Also if the motherboard is failing I'd preferably go with H77 or Z77 chipset instead of H61 as an upgrade, thus kindly suggest a few boards.

    Thank you.

    The very first thing I would do would be to swap in a quality pw supply. If you really have a 250W pw supply, you are just asking for a problem. If you reference your mb manual, page 14 states a minimum of 500W is recommended. Note that is the online manual. The paper manual might have the info in a slightly different place.
    When you use a pw supply that cannot adequately pw the system, it [pw supply] works at its maximum output. Using anything at 100% of rated pw all of the time will shorten the life.

    Just think how long the engine in your car would last if you ran it at full throttle ALL of the time??? That is what you are doing.

    That appears to be an iBall JSW 252 250W power supply that sells in India.

    That mother board requires a minimum power supply of 500w:

    "It is recommended that a power supply that can withstand high power consumption be used (500W or greater). If a power supply is used that does not provide the required power, the result can lead to an unstable or unbootable system." That is from the owners manual for that motherboard.
