Hello

Having a bit of a problem with my pc. Basically, my computer turns on but there is no display on the monitor. I fixed this by replacing the CMOS battery and this went good for like 2 months or so. The problem started when it happened again so I again replaced the battery. This fix only lasted like 2 weeks and now it's happened again. What I do at the moment to access my computer is take out the CMOS for like 5 mins and put it again. This seems to fix the problem but after a day the problem shows up again. I'm getting sick of doing this process every single day so I would like to know what is happening with my pc. Do you guys think this is due to a faulty mobo? Any help w...

Hello,

Yesterday, I was thinking of upgrading my RAM. I bought 512 MB SD RAM, but when I opened my CPU I realized that I am not sure if my machine has SD RAM in it. So, I didn't put the new RAM. I then tried to switch on the machine to run some utility for checking my RAM type.

Unfortunately, when I switched on my machine, my display didn't come up. Now, I am having no clue what went wrong as everything looks fine but there is no display.

When I disconnected my monitor from the CPU, I get a test message as no signal. My monitor looks fine. Please help in sorting the issue out.

Thanks in advance.

Regards,
Syste...
