hi all i'm having some serious trouble with my PC i got my Lite-On combo drive that i ordered from digit on the 6th. after surfing the net for some time, i turned off the pc and got to installing the drive. i fitted the drive as secondary slave, connected all the cables and the turned on the pc but it didnt boot. instead i got the beeep sound that is heard when the ram is badly conncted/not installed/bad. i thot the jerks on handling the cabinet mite have loosend the slot. so, i opened the cabinet again and double checked if the ram was loose i also checked for ANY faulty connections and found none. so i again turned on the pc but no luck again, after checking for ANY sort of faults for over 2 hrs, the pc seemed to boot normally(the single beep and all). it showed the lite-on drive at startup but stopped just afer that showing this msg: IDE 80 cable is not connected (or something like that) i tried a few more times and then it seemed alright when i got into GRUB. i logged into windows xp (sp2 installed) and everything seemed smooth, Lite-On drive was detected and i put in the digit DVD...the drive was working like a charm....but after 5 minz, the pc froze(i cant find a more suitable word). yeah it just froze - no error messages, no BSOD, even the mouse pointer wasnt moving. i cold rebooted and this time things seemed worse. the pc froze on the GRUB screen with 7 seconds remaining. i cold rebooted again and this time, tried to log in win 98. but the pc froze at the windows 98 startup spash screen. i then tried logging in fedora core 2...this time the pc froze when i got into GNOME.i checked for all the fans(the proc and smps) and found that they were working even when the pc was frozen. i thot maybe my hdd is faulty and so, i put in SLAX LIVE BOOT in the new dvd drive and booted...i was able to use SLAX for abt half an hr, when that froze too, when i was listening to mp3s. this assured me that it was a h/w fault. and after that, when i start the pc, sometimes, it just freezes AT THE START UP PROCESS. it sometimes shows : Intel pentium 4 2 GHz and thats it....sometimes, the screen just doesnt even turn on at startup. and all the time when the pc freezes, the tiny red light on the cabinet never glows(the light that shows if the pc is busy or not) i called up a service guy and after checking he said that the smps was faulty and that was the reason. i somehow found that reply unsatisfactory. now, i logged in win xp for a last time to post this, but, when i tried to connect to the net, i got a msg that Modem was not found. i checked in the device manager and then found that the Modem and TV capture card was missing. i tried to add them thru the device manager, but no luck....it seems like the pci slots r missing. and the hardware doesnt get detected in any OS. (FC2 warned me abt modem not being detected at startup). and its not the driver fault. NOW, i wanna know why my pc is FREEZING like this. SOMEONE PLEASE HELP ME WITH THIS!!! my configuration: Intel P4 2 Ghz Intel 845 chipset mobo 256 mb sdram (single stick) 60 gb samsung hdd samsung 52x cd rom liteon 52x32x52 combo conexant chipset 56 kbps modem frontech tv capture card (actually rebadged lifeview prime 30 card) OSes installed: Win xp home sp2 win 98 fedora core 2 PLEASE HELP!!!
