I'm taking a guess here, dimly recall that this combination pointed to issues with the Ram. Suggest you remove each module in turn and reboot with one in at a time.
If that fails, I'd whip out the CMOS battery and replace it after 30 seconds.
Failing that, without any bios beep codes, I can only suggest that you see if the CPU heatink is getting warm, which would indicate at least that the CPU is still active.

My last guess is that there is a failed component on the motherboard

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty

make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty ?

Have you checked the keyboards light? Is it lit? When you press on the CAPSLOCK button, does the light changes in the keyboard?

Try to unplug the hard drive, and DVD from the mobo and see if it goes well.

If no go, try removing the RAM sticks and see what's on the screen when you turn it on. Then put each part back one by one, checking the computer for any change or something like that.

Will not spin


Some of the Wash Progress LEDs flash when the machine stops due to a fault. The 8 Wash Progress LEDs stands for the binary digits and by indicating the digits, the fault code number is determined. The fault code can be shown by activating Diagnostic Mode if none of the Wash Progress LEDs are lit.

Turn machine OFF on the control panel then hold down the Water Temp Down button and press the POWER button until the machine gives 2 short beeps and lights up. Release buttons and you are in Diagnostic mode. Press the Spin Speed Up button 3 times until the Hold and Slow LEDs are lit. Write down the LEDs which are lit across the Wash Progress LEDs and post it back.

When I push button to turn on, the light flashes orange. Nothing happens, no fan, nothing. It worked fine yesterday.


This usually means a failed power supply and/or failed system board. No way to know further without swapping parts. Power supply is cheaper to replace .

Laptop powers on but will not boot. Keyboard lights remain on. Disk light comes on for a second and then goes out.


For all troubleshooting, have the notebook connected to the DC power supply.
Does the power stay on? if the power goes off are you getting any beep codes or do the leds flash in a specific pattern? if no beep/led codes, and system turns off, then it's likely to be a bad system board or cpu. if power stays on, but you see nothing on the display, the lcd could have gone bad. can you connect an external monitor to this unit?

Either the new power supply you purchased is not functioning correctly. But, assuming it is now that you are getting some form of power to your PC, it is very likely the motherboard. Whatever fried your old power supply (or it could have just been the power supply itself) most likely fried your motherboard in the process. Probably not the CPU since the MB can't even post.

Toshiba satellite A60 no boot


We can only assume that because the cd drive operates then the motherboard is operating in part, although, the southbridge chip may be damaged, as the northbridge works memory etc. Maybe it is that the processor is fried as there is no fan and the system then shuts down. Toshiba are probably half way there with the answer, unless; they investigated further and decided it was not the processor but the motherboard.
