The i5-660 is listed but did you notice the minimum BIOS and board revision numbers?
You can imagine the poor soul that got a board that didn't meet the spec.
Started thread on another site, but got no straight answers.
Intel i5 660
Intel DP55WB Mobo
Thermaltake CPU Cooler (Using the stock Intel right now for testing purposes)
G.Skill Ripjaws 8GB DDR3 1333, PC3 10666, CAS Latency 7, 7-7-7-21, 1.5V
Asus GT440 Video Card
WD Caviar Blue 1 TB
Samsung Disc Drive
OCZ ModXStream 700W PSU
Developments from the last thread are that I RMA'd the RAM, Mobo, and PSU, because I thought it'd have to be one of those.
Still getting the same problem (YES I did breadboard it first). This is
NOT my first build. All the connections have been thoroughly checked,
all components properly seated.
Hooked all up on a bench. When the PSU is switched on the system
instantly powers up (fans, drives) but no POST codes (exception below).
Removed ALL but CPU and CPU Fan. Disconnected everything from mobo as
well. When PSU switched on system powers up, gives three long beeps
Added one stick of RAM next, didn't get any POST codes. Tried in all 4
RAM slots, still no POST. (also tried with 2 different sticks). Removed
RAM, reset CMOS. Still same.
I think that the CPU may be bad. Although I shouldn't get a POST code
(without RAM) if the CPU is bad, should I? At this point I've tried 2
video cards, 2 motherboards, 4 sticks of RAM, and 2 CPU fans...
Also, somewhere else it was mentioned that it could be an incompatible RAM timing?
A few years ago we had to pop in another CPU to see what BIOS it was and update that to support the newer CPU.
Fortunately for us we had the CPU in the shop stores and could rectify the issue. For those that don't have access to such you RMA the board and demand it has the support and revision to support your CPU.
What you're getting is a pre-POST error code with the RAM. I'm a bit dubious on the RAM timing idea, but I suppose you can always check it against your motherboard's manual to make sure it seems within spec. Other than that, I would say you've pretty well done everything else I would have suggested for troubleshooting, and left little else it could be than the CPU.
I will also assume that before buying you were sure that this particular CPU and motherboard combo would work.
You might want to look at this page.
Seems to be some differences between proc spec/mobo rev/bios.
You've got the parts....maybe you can make sense of it.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
