Loss of Graphics - need information
by: Anonymous

I have a Hewlett Packard Compac desktop computer and the problem I have is a regular loss of graphics for no particular (or apparent) reason.

I regularly have to use a windows repair disc, which leads me to conclude I have a faulty computer.

From: Kris at Build Your Own Computer:
What's the age of your pc? Have you replaced computer components recently? Or changed software? I need some more information from you before I can provide assistance or help.

Building My Own Computer - Next Step
by: Ryan

Thanks, Kris. You may have just identified my problem, as I do not have a CPU cooler installed. The mobo and processor are new, and on startup the processor and RAM were detected. I'll get a fan and install that to see if it works.

Thanks again,

Ryan

Build Your Own Computer
by: Kris

Hi Ryan,
Sounds like a bad CPU pin connection between the new motherboard and the CPU/Package from the old machine.

Often when transferring components back & forth like a CPU, the pins are not seated or aligned properly in the MOBO socket receptacle. Even if they are the pins from a used component or CPU may have slightly altered, 'corroded' or tarnished over time. Gently remove CPU & observe the pins, re-seat or lower back in the new socket, close & lock the gate lever. Re-install CPU Fan/Cooler assembly - most new Mobo's will shut down if there is NO CPU FAN attached - its should have a three pin connector, (the 3rd wire is for speed sensor).

Try to re-assemble system in strong daylight, use only the minimal components, only (one stick of ram, 1 H.D. etc) also whenever a new or different CPU is installed in a compatible motherboard, the
MOBO and bios has to identify that CPU correctly, and make ready its operating parameters like a clock multiplier etc. (look in bios menu/the CPU
feature section)

Also a reminder, brand new power supply connectors and others,are quite stiff and sometimes fit very tight to the sockets, this can generate and transmit shocks throughout the MOBO when inserted and removed, nice & steady push, & small rocking & wiggle pulls should minimize this ...
hope this helps isolate the trouble.
regards, Kris
