When I try to turn on my computer, it turns on, but the
monitor screen stays black, and the littl light of the
monitor is yellow. All the cables are connected, also the
computer seems to freeze instantly when I turn it on.
What could cause that?
It means you have hardware problems. The video card could be bad, it
could be the monitor, the processor, the motherboard. There's no way to
tell from your post. Here are general hardware troubleshooting steps,
but I do think you should just take it to a good local repair shop for
fixing:
For hardware issues - 1) open the computer and run it open, cleaning out
all dust bunnies and observing all fans (overheating will cause system
freezing); 2) test the RAM - I like Memtest86 from
www.memtest86.com -
let the test run for an extended (like overnight) period of time -
unless errors are seen immediately; 3) test the hard drive with a
diagnostic utility from the mftr.; 4) the power supply may be going bad
or be inadequate for the devices you have in the system; 5) test the
motherboard with something like TuffTest from
www.tufftest.com. Testing
hardware failures often involves swapping out suspected parts with
known-good parts. If you can't do the testing yourself and/or are
uncomfortable opening your computer, take the machine to a good local
computer repair shop (not a CompUSA or Best Buy type of store).
