Check the RAM. Try removing the power cord from the psu and push the power button to reset.
Hi, I really hope you cnet gurus can help me.
My PC won't start-up correctly. It was fine yesterday then today it just won't start-up - what will happen is it will come on for 1/2 a second then switch off completely. There aren't any unusual noises or beeps. When the PC turns off, the front blue LED light around the power button keeps flashing very slowly.
It got me completely baffled because I have a good Q-TEC 550WP Dual Fan Gold PSU connected to: MSI 6741 motherboard, AMD Athlon 3400+ CPU, AGP nVidia GeForce 6800Ultra, two IDE 200GB Western Digital Caviar hard disk, two NEC 3420 DVD-RWs, two sticks of DDR-SDRAM 512MB 184-pin 2700, Gigabit LAN PCi card, Creative SoundBlaster Audigy 2 Value PCI card, floppy and a external Maxtor 200GB USB2 drive. I'm running Windows XP Pro with Service Pack 2.
I've tried tirelessly to resolve it by trying the following in separate attempts then tried to start the PC without any success: removing the graphics card, removing the LAN card, removing the sound card, unconnected the back case 8" fan, unconnected the front case bottom 8" fan, unconnected the exhaust fan.
I'm open to any suggestions here and need the PC up and running soon, otherwise it's off to a PC repair shop as a last resort - something I can't really afford to do.
