Replace the CMOS battery? That's what keeps time.
That STM380215A is very old. You can get an 120GB SSD for cheap and it would help the overall speed. https://www.google.com/#q=fry%27s+120gb+ssd
I don't see anything wrong with old PCs except folk tend to think they are slow.
So my computer used to run like a beauty, but as of late it's slow, laggy, keeps cutting off from internet, sometimes can barely run internet (slow, laggy), the time & date keep reverting to 2007 every time it's started, usb ports sometimes disconnect & once or twice it's frozen & I've had to restart.. I've tried wiping it clean & reinstalling all software but this doesn't seem to help. Not sure if my system itself is just bust or if this can be sorted. I haven't installed/downloaded anything new that could be causing it, it just started randomly happening. Also, I know it seriously needs an upgrade but I'm keeping it as is as I'm currently building a second computer with better specs & keeping this one for older games.
Not sure which specs you'll need to help me figure this out but I've listed the ones I know off hand below.
MB - Gigabyte M61PM-S2
CPU - AMD Athlon 64 X2 Dual Core 4200+ 2200MHz
GFX - Nvidia GeForce 7300 GT
HD - Seagate ST380811 0AS SCSI & Maxtor STM380215A
OS - Windows XP/7 (Dual Boot)
Thanks in advance!
