Hello Experts, I have IE5.5SP1 on Win98SE. Serious problem and the story would be L O N G. I use iMesh file sharing program. Last night I was downloading a very large file (about 17 MB). I set my PC to disconnect internet at 8:00 AM. At about 7:30 AM, power supply of our area of the city failed. Then it came back after 2 to 3 minutes. My PC doesn't start automatically in this situation. When I pressed the button to start it, it ran scan disk (blue environment with yellow progress bar). After completing it, the whole screen turned blue and further functions ceased. I pressed restart button. PC tried to access hardware, hard drive ran for some time and then everything hung. No beep or no appearance on monitor! Everything black! I turned off power supply (my British friends can understand that how), I tried to start it after half an hour. But same situation. I tried to start it after one hour but no response. I turned on air conditioner to cool down the PC hardware (in case its problem was hardware heating up). But all in vain! I called my friend who has a bachelors degree in Computer Sciences. He came and started the PC but no beep and no appearance on screen. I told him whole of the previous story. He said "some time bomb virus has activated and it has burnt PC's BIOS. Maybe, you'll not be able to recover your C drive data at all". I keep my system always armed with all kinds of anti-virus weaponry (imported from USA) (I mean Norton antivirus and its fortnight upgrade via internet.) I told him about my security settings. He said that such viruses can dodge security settings and perhaps this was a new one. He told that we needed to take the PC to some repair shop. I planned to go to for repairing it tomorrow. After my friend's departure, I tried to start the PC again. I pressed the power button many times instead of one. It tried to start and then turned off (it never turned off before automatically; I had to cut off power manually.) I pressed the power button again. Surprisingly, system turned on normally. I immediately launched AV, and ran full system scan. After 20 minutes, while AV was scanning PC, screen saver (setting: Blank Screen) appeared and PC became stuck. I restarted PC by pressing Restart button but same problem; no response, beep etc. I pressed the button repeatedly. Computer turned off. I pressed power button and computer turned on normally. (Phew!) And now I am mailing you. Can you help me in diagnosing the problem? Any ideas will be highly appreciated.
