Question My pc do not start untill I reset my ram...

[Usghani]

I turned on my pc after a month it did't show any thing on screen, I checked everything it was fine , both CPU and PSU fans were working but pc didn't show any thing on screen after one minute PSU fans start spinning at very high speed so I cut off power.
Than I reset my ram , pc boot up normally , after 3 hours working fine I shutdown my pc and after a day when I tried to turn it on again it didn't show any thing on screen while everything is going fine. Again after resetting my ram it boot up.
I cleaned my ram sticks , checked them one by one, test them with windows memory diagnosis tool no errors were found.
Even I reset my bios but problem is same, when I restart my pc it works fine but when I shutdown my pc it won't turn on until I reset my ram.
Please help me.

Think I also have the same problem. Will re-plug my RAMs and see if it works.

After shuting down my pc when I try to start it again it doesn't show anything on screen, no beaps while all the fans are running and after 1 minute PSU fan start running at full speed.

1. I assume you're using 2 2GB RAM modules. How are they seated (X - X - X - X)?

2. My initial reaction is that the CPU needs new thermal paste. Something is building up, and after a few hours the fans go crazy: Could be the CPU overheating because of old and ineffective thermal paste.

3. When was the last time you cleaned your PC?

I clean my pc after every month.
