There was a lightning strike very close to my home. My desktop was off at that time, but was connected to the power supply and the internet cable. When I switched on the PC after the strike, the PC's clock had been reset and showed 12 AM 1st January 2005. The PC's USB ports are no longer working and everytime I start the PC, it takes 2-3 minutes to start. What could be the problem?
hands off, think it was affected by lightning. with lightning power, you never know what damage it can cause even you're directly affected. trying out other psu would be a good start to isolate problems.
First, test your PSU with a multimeter to make sure it's producing the correct voltage without flucuating. If it is not, you need to replace it because it could mess up other components of your computer. After you've done that and have verified that you are using a good PSU, look for a button to press for "Setup" when the computer boots. It will probably be F2, F12, or something like that. Hit that, then look for diagnostics. Run the diagnostics if you have them to check for errors. If you don't have diagnostics on your computer or can't find them, you might be able to find a free program online to check your computer's components.
Hey, The posters are right. You should test your PSU. The problem is either a bad motherboard, bad power supply, or bad both. My friend had a similar experience, except his PC would just not turn on. He got a quote of $1100 fro a PC repair shop. I opened up the PSU and replaced a $.037 fuse. I saved him a few bucks.
I had the same problem few years back and it had damaged my SMPS (PSU) and on board LAN card. Your slow start is probably due to the damaged LAN card. Have it checked or replaced and you would be fine. Regards, RightMan
I agree with above posters first of all open your (PSU) power supply unit check it if you don't know how to check pm i will brief you in detail if it is working properly then check you BIOS chip on your mother board go into setup option reset the date and related if it doesn't work replace the chip.
Update: The PC is working fine now. The motherboard had been damaged, but as the PC was under warranty period, it was repaired by the company at no cost. .
