Hello,

Check this question out, I am VERY confused.

I am a student at Michigan Technological University. I have my computer up here and about 2 days before I went home for Christmas break, it stopped working. I can boot up the computer but I get no video on the motherboard, my mouse does not turn on, and my keyboard does not work. I tried everything possible including taking everything out of the case and just running the computer with the mobo, processor, and video card; still did not work. I brought this home for the break so I could look it over even more. When I decided to look it over, EVERYTHING worked just fine. Computer booted up, video card worked just fine, keyboard turned on, mouse turned on, everything. I have no clue what the problem could be and am very confused.

If anyone has a clue as to what could be happening, I'd love any suggestions.

Thank you,
Blake Carlson

sometimes the BIOS or CMOS configuration can prevent comp from booting. by taking out battery & putting it back ; you reset the BIOS. that might have solved the problem
I have tried this several times and still no result. Thanks for the help though.

Is your comp fixed or not working?
It still is not working. I was thinking that it could possibly be a motherboard issue, but why would it not work at school, work just fine at home, and then not work at school again?

Then try this:

1) Check that the exhaust areas are completely uncovered and that there is enough air for ventilation

2) Try vacuum cleaning the fans. Dirt, dust and even cobwebs may cause problems. Clean the inside as well as the outside. This is also a possible soln for other hardware problems

3) Maybe the input voltage is too low(or too high); so check the socket too.

4) Check the internal wiring(remove and re-insert all loose connections); and also the USB ports. If the pins there are bent, comp wont work properly
