My computer would not turn on at all the other day, had been having slight issues with it for a while, mainly powering up but once running it was fine. Thought it might have been a psu failure so I swapped my psu and removed my graphics card. I have a dual boot system, both windows 7, on 2 separate SSD drives. It would not touch my ssd drive with my day to day version of windows 7 on it but would boot to my original install on my original ssd drive.
I then reset my BIOS and tried booting as normal & I could then boot to both copies of windows, restart, shutdown and power up as normal.
I then put my graphics card in and nothing. Power on, fans turn but no signal & no power to keyboard or mouse. Removed card and still nothing. Reset BIOS again and then it was running again (without a graphics card & after changing BIOS to AHCI)
I then put my old, but working, graphics card in the same slot and nothing. Removed card & had to reset BIOS to get it to boot up again.
I am assuming my MOBO is playing up as it seems to forget things once you use a PCIe slot. The date & time are correct so it does not seem like the battery is flat. I shall remove the battery to clear the CMOS tonight hopefully (could have done it last night but watched that awful England game instead)
Spec is
GIGABYTE GA-Z77-D3H Intel Z77 (Socket 1155) ATX Motherboard
Intel Core i5-3570K 3.40GHz (Ivy Bridge) Socket LGA1155 Processor
8GB (2x4GB) Corsair Vengeance Jet Black Low Profile 1600MHz CL9 DDR3
240GB Mushkin Chronos 2.5″ SATA 6GB/s (SATA-III) Solid State Drive
MSI HD 7850 Twin Frozr III OC 2048MB GDDR5 PCI-Express Graphics Cards
I shall have another fight with it tonight but if anyone has any ideas then it would be much appreciated. All the components are less than a year old so I could claim on warranty but I need to find out which part (or parts, if any) is faulty.
Many thanks,
Garyb

You don’t need to remove the battery, just use the CLR_CMOS jumper (that’s why it’s there). I’ve seen posts where some people take the battery out & leave it out overnite to make sure the BIOS clears – it only takes a couple of second to clear, not minutes or hours. Just make sure the power cord is unplugged because the PSU standby power can prevent the BIOS from resetting.
From your motherboard manual:
• To clear the CMOS values, use a metal object like a screwdriver to touch the two pins for a few seconds.
• Always turn off your computer and unplug the power cord from the power outlet before clearing the CMOS values.
