1391015	2014-12-27 02:08:00	I just installed a Cooler Master Hyper 212 EVO - CPU Cooler with 120mm PWM Fan. I believe I followed all the directions and the fan works fine. The problem is the computer now does not send a signal to my monitor. I think something happened to the CPU. I have left the computer running for an hour and fins are all cool to the touch. When I removed the old CPU fan assembly the CPU came out also. I had quite a bit of trouble getting the CPU to come free of the fan assembly. The paste seemed to become like glue. I finally got it to come apart. I inspected the connections on the CPU and I think they all looked fine. I put the CPU back in the motherboard and spent quite a bit of time cleaning the top of the CPU of all the old hard paste. I then attached the CPU Cooler to the CPU and turned on the computer. Then the monitor gave me the message - no signal. So I am assuming I somehow messed up the CPU since after more than an hour if it was working I should be able to feel some heat from the cooler, but I don't. Any suggestions on how to fix the problem? Thanks	Columbuslee (16989)
1391016	2014-12-27 02:42:00	Some questions just to rule out something not so obvious: When you put the Cooler on, did you re apply heatsink Paste and make sure its seated fully ? Did you try the original Heatsink ? I had quite a bit of trouble getting the CPU to come free of the fan assemblyHow did you take it off eventually, (just in case something you used caused damage) Along those lines, what type of CPU is it ? Some its impossible to remove the CPU from the board without the heatsink being off first. Did you disconnect the Monitor cable ? if so make sure its on the right connection - this applies usually if you have onboard and a graphic Card. If you have both you have to connect to the card, as it will over ride the onboard giving that message.	wainuitech (129)
1391017	2014-12-27 05:59:00	When you put the Cooler on, did you re apply heatsink Paste and make sure its seated fully ? I used new paste (Arctic Siliver) Yes I believe it was fully seated. Did you try the original Heatsink ? The original heatsink used a different bracket. I had to remove it to use the bigger heatsink. I had quite a bit of trouble getting the CPU to come free of the heatsink fan assembly How did you take it off eventually, (just in case something you used caused damage) Along those lines, what type of CPU is it ? Some its impossible to remove the CPU from the board without the heatsink being off first. I called a computer repair facility and was told that the paste was not glue and I should be able to separate the CPU from the heatsink. I used a craft knife and kept working at the edges of the CPU. It finally came loose. What was strange when I lifted the heatsink assembly out of the motherboard the CPU came with it. The CPU isa AMD PHENOM II X6 1090T BE AM3. The motherboard is a ASUS M4A88TD-V EVO/U3 AM3 ATX. To clean the CPU I used pre moistened lens cleaning tissues that contained alcohol. Did you disconnect the Monitor cable ? if so make sure its on the right connection - this applies usually if you have onboard and a graphic Card. If you have both you have to connect to the card, as it will over ride the onboard giving that message. I used an HDMI connection from the graphics card (EVGA GTS450 1GB DDM FPB PCIE). I also tried to connect it to the HDMI connection on the motherboard and that did not work either.	Columbuslee (16989)

1391019	2014-12-27 09:27:00	Few things to check. Did you reconnect the cpu power to the motherboard. Assuming you removed the board to do this, is it now sitting correctly on the case standoffs. Must have taken a fair wrench to remove the cpu without releasing the locking lever. Could have damaged something there.	Driftwood (5551)
1391020	2014-12-28 17:16:00	[QUOTE=Driftwood;1213322]Few things to check. "Did you reconnect the cpu power to the motherboard." I did not remove the motherboard to install the new heatsink. I have looked all over the motherboard for connections that are not plugged in and I have not found any. The fan on the heatsink runs and it is connected to the motherboard and it is working. "Assuming you removed the board to do this, is it now sitting correctly on the case standoffs." Everything looks the same. "Must have taken a fair wrench to remove the cpu without releasing the locking lever. Could have damaged something there." It seemed to me that the cpu came out quite easily. But, the cpu and heatsink were stuck together to the point I felt it was glued on. All the fans and power supply are working. The hard drive and cpu are not. (If the cpu was working it would start to warm the heatsink and it has not) I do not know what to do or what steps I should take to get it to work. Other than just buy another cpu.

Any suggestions on how to fix the problem? Sure you put it back in the right way round? I saw one once that someone had managed to insert turned at 90 degrees. It killed the CPU of course, the pins don't line up and he'd mashed some. Anyway if the CPU is damaged, you can't fix it, you'd have to find another....	pctek (84)
1391022	2014-12-28 22:02:00	The one thing I am sure of it that I put the cpu back in correctly. If there is a problem with the cpu how do you check it out to see if it is the problem?	Columbuslee (16989)
1391023	2014-12-28 22:26:00	Try it in another (compatible) machine. Try another CPU in your board. Yes, that means buying more bits just to test, if you don't otherwise have access to them.	fred_fish (15241)
1391024	2014-12-28 22:36:00	Were any of the motherboard led's coming on when you fired it up?	Driftwood (5551)
