Updated with system specs: Expert/Advanced Help needed.
Tried everything? The display was working, until the PW and CMOS were cleared.
I can't get it to post/boot so I cannot verify below, but I believe it to be accurate.
Dell Inspiron 660,64 bit, Intel Core i5, Intel B75 express chioset, with Windows 10, preinstalled with 8
1333/1600 Mhz DDR3
Dell monitor and HP monitors tried,
4 pin USB keyboard, and 4 pin mouse (MSI)
Memory = 2x SK hynix 4gb 1Rx8 PC3-12800U
2,4-pin usb 2.0 and 4, 9-pin USB 3.0
Video=integrated HD Graphics with 64-256mb Video memory (not sure)
HDD= SATA 7200 RPM Seagate Barracuda 1000 GB
MB = E145B3 MS1003
MIB75R/MH_SG MLK MB
11068-1
48.3HD01.011
PS =dell B300NM-00, 300 WATTS
Service Tag= 6kcdny1
No post, no display after clearing CMOS password with jumper and CMOS battery. It powers up, power light on green and steady, keyboard lights up, cd/dvd drive spinning and all fans running, but no post, no video (it should have 1 post beep and then boot). I also tried booting from a recovery disk, repair disk but nothing. Nothing happens with any Fkeys on keyboard. 2 working displays tried. (1 hdmi, 1 regular blue) Still no display, no post. Also, unplugged and reseated all cables to mb and to hdd, and everything else.
This is what else I have checked:
1. 300 watt power supply, with voltmeter. 24 pins good, including the gray "power good". 4 pin mb power, good. CMOS battery 2.5v. Replaced wih new 3.1v.
2. disconnected everything from MB, except power, power on switch, processor fan and processor. Plugged in waited 5 minutes, and turned on. 5 beeps for CMOS battery failure. Power off, grounded self, (reinreinstalled battery). Restart. 2 beeps for memory (as expected)
3. Unplug, ground, reinstall 1 of 2GB memory stick. Plug in, turn on, no post.
4. turn off, Unplug, drain power, disconnect everything from mb. remove mb from case. Checked for loose wires, swollen/leaking transistors, bent pins. On a board, plugged in 24p cable power supply and 4 pin cable to MB. Jump started. all fans running, lights on power supply, but no post.
5. Removed heatsink fan and heatsink to visually check it out. Nothing looked odd.
So, if its the motherboard, why does it power up and give error beeps?
I need the Windows 8 IOS/product key from the motherboard, which is why I keep trying. If I just replace the mother board, I lose the operating system and the other preinstalled programs. Can anyone help? Please, only offer advise, if its something I havent already tried. Thank you in advance.
