Hello everyone,
As your forums here at VOGONS never failed to provide me with valuable advice as well as others, and as someone who is far from being an expert, I would like to request your help one more time:
Basically, I bought a Celeron PC in a yard sale, and at the time I cleaned it the best that I could, and I proceeded to format it and use it for about 3 years. I can't remember why, but I installed a power supply that came from a Pentium IV at the time.
Given that the PC was always loud and had a slight old cupboard type smell, even after the cleaning, last week I decided to change the heatsink and cooler, and took the opportunity to change from this Celeron 600mhz to a Pentium III 866mhz.
I couldn't confirm what my motherboard was, I'm 90% sure it is this obscure model: http://www.motherboard.cz/mb/sg/SG-APP133AB3.htm
I got the new CPU today, so I dismantled the case and gave a deep clean to the power supply, case and components, removed the heatsink, cooler and Celeron CPU, and put the new CPU in. As I am still waiting for the heatsink, cooler and thermal paste to arrive, I just wanted to do a quick boot with only the CPU in the socket to confirm that the Pentium III 866mhz was recognised, and turn off the PC immediately.
Unfortunately, the computer turns on but I got no image, and it's almost as if the motherboard is underpowered, the front panel lights of the case don't even turn on, and the power supply is very "chill" and quiet in its activity.
Later I switched to the Celeron again, with only the CPU in the socket as well, and got the same thing.
Did I:
1. Fry the CPU by turning the PC on without thermal paste and heatsink?
2. Did something to the power supply when I cleaned it?
Do you think you can help me with this? Thank you so much for your time and your attention.
Best regards,
André
